What Is Bio-Oil Skincare Oil and What Does It Do?

 

If you've ever searched for something to help with scars, stretch marks, or persistently dry skin, chances are you've come across Bio-Oil skincare oil. It's one of the most widely recognised topical oils in the UK, and for good reason. Formulated with a blend of plant extracts and vitamins suspended in a lightweight oil base, it's designed to improve the appearance of a range of common skin concerns — without requiring a prescription. You can browse the full range of skin care products at Cured Pharmacy to find the right option for your needs.

Bio-Oil has been clinically tested and is available over the counter across the UK. It's suitable for use on the face and body, and its oil-based formula means it absorbs relatively quickly without leaving a heavy residue. Whether you're dealing with post-surgical scarring, pregnancy-related stretch marks, or simply skin that feels tight and dehydrated, this product is worth understanding properly before you start using it.

 

How Does Bio-Oil Skincare Oil Work?

 

The key to Bio-Oil's formulation is something called PurCellin Oil — a synthetic equivalent of the preen gland oil found in ducks. It acts as a texture modifier, making the overall formula thinner and easier for the skin to absorb. Without it, the vitamins and plant extracts in the product would sit on the surface rather than penetrating the upper layers of the skin.

  • Vitamin A (retinyl palmitate) — supports skin cell turnover and helps improve skin texture over time
  • Vitamin E (tocopheryl acetate) — an antioxidant that helps protect skin cells from oxidative stress and supports moisture retention
  • Calendula oil — known for its soothing properties, particularly on sensitive or irritated skin
  • Lavender oil — traditionally used for its calming effect on the skin
  • Rosemary oil — contains antioxidant compounds that may support skin health
  • Chamomile oil — gentle and soothing, often used in products for reactive skin types

Together, these ingredients work to hydrate, soften, and gradually improve the appearance of scarred or uneven skin. Results aren't instant — consistent use over several weeks is needed before visible changes occur.

 

Who Should Use Bio-Oil Skincare Oil?

 

Bio-Oil is suitable for a wide range of people and skin concerns. It's appropriate for most skin types, including sensitive skin, though a patch test is always advisable before applying it to a large area. It is not suitable for use on open wounds or broken skin.

  • People with post-surgical or injury-related scars (once the wound has fully closed)
  • Pregnant women looking to reduce the likelihood or appearance of stretch marks
  • Anyone with dry, dehydrated, or flaky skin on the body or face
  • Those with uneven skin tone or areas of hyperpigmentation

Feature Bio-Oil Skincare Oil Silicone Gel Sheets
Form Topical oil Adhesive sheet
Primary use Scars, stretch marks, dry skin, uneven tone Raised or hypertrophic scars
Ease of use Massage into skin twice daily Apply and leave in place for hours
Suitable for large areas Yes Limited by sheet size

 

Is Bio-Oil Skincare Oil Safe for All Skin Types?

 

Generally speaking, yes — but with some caveats. People with known allergies to any of the plant-based ingredients (such as lavender, chamomile, or calendula) should check the full ingredient list carefully before use. Those with acne-prone skin should be cautious, as oil-based products can occasionally worsen breakouts in some individuals. If you're exploring other topical options alongside this product, you might also find our range of creams and ointments useful for complementary skin treatments.

Store Bio-Oil below 25°C, away from direct sunlight, and keep it out of reach of children. Do not apply near the eyes or on open skin. The NHS advises that any new skincare product should be patch tested on a small area of skin before wider use, particularly if you have a history of skin sensitivity.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Bio-Oil Skincare Oil

 

What Is Bio-Oil Skincare Oil and What Is It Used For?

 

Bio-Oil Skincare Oil is a topical, non-prescription skincare product used to improve the appearance of scars, stretch marks, uneven skin tone, and dry or dehydrated skin. It contains a proprietary blend of plant extracts and vitamins in a lightweight oil base, designed to be massaged into the skin twice daily. It is not a medicine in the traditional sense — it does not treat underlying medical conditions — but it is widely used as part of a skincare routine to address visible skin concerns. The NHS notes that keeping skin well moisturised can support the healing process and improve the appearance of scars over time.

 

What Do You Need to Know Before Using Bio-Oil Skincare Oil?

 

Before you start using Bio-Oil, there are a few important things to be aware of. It is intended for external use only and should never be ingested. Always read the label and, if in doubt, speak to your pharmacist.

Do not use Bio-Oil if:

  • You are allergic to any of the ingredients, including lavender oil, chamomile oil, rosemary oil, or calendula oil
  • You have open wounds, broken skin, or active skin infections in the area you intend to treat
  • You are applying it near the eyes or mucous membranes
  • You are using it on a child under 2 years of age without medical advice

Warnings and precautions:

  • Perform a patch test on a small area of skin 24 hours before first use, particularly if you have sensitive or reactive skin
  • If you develop redness, itching, or swelling after application, discontinue use and consult a pharmacist or GP
  • Pregnant women should consult their midwife or GP before use, even though the product is widely used during pregnancy
  • People with acne-prone skin should use with caution, as oil-based products may not suit all skin types

Known drug interactions:

  • No clinically significant drug interactions have been identified for topical use of Bio-Oil
  • If you are using prescription topical treatments on the same area of skin, speak to your pharmacist before combining products

 

How Should You Use Bio-Oil Skincare Oil?

 

Consistent application is essential. Bio-Oil does not produce overnight results — most users need to commit to at least three months of regular use before seeing a meaningful improvement. Here's how to use it correctly:

  1. Ensure the skin is clean and dry before application
  2. Pour a small amount of Bio-Oil onto your fingertips — a few drops is usually sufficient for a localised area
  3. Massage the oil into the skin using small, circular motions for at least two minutes
  4. Allow the oil to absorb fully before dressing or applying other products on top
  5. Repeat twice daily — morning and evening — for best results
Indication Age Group Dose Frequency
Scars Adults and children over 2 Few drops, massaged in Twice daily
Stretch marks Adults (including pregnant women) Few drops, massaged in Twice daily
Dry skin Adults Few drops or more depending on area Once or twice daily
Uneven skin tone Adults Few drops, massaged in Twice daily

 

What Are the Possible Side Effects of Bio-Oil Skincare Oil?

 

Bio-Oil is generally well tolerated. However, as with any topical product containing plant-derived ingredients, some people may experience a reaction. If you're also managing other skin conditions, you might find it helpful to explore our range of creams and ointments for complementary options.

Common side effects:

  • Mild skin irritation at the site of application
  • Temporary redness or warmth after massage
  • Greasy feeling on the skin if too much product is applied

Less common side effects:

  • Allergic contact dermatitis — characterised by itching, rash, or blistering
  • Worsening of acne or blocked pores in acne-prone individuals
  • Photosensitivity in rare cases due to certain plant extracts — avoid prolonged sun exposure on treated areas

Stop using Bio-Oil immediately and seek advice from a pharmacist or GP if you experience a severe allergic reaction, including significant swelling, difficulty breathing, or widespread rash.

 

How Should You Store Bio-Oil Skincare Oil?

 

Correct storage helps maintain the integrity of the product's ingredients. Follow these guidelines to ensure it remains effective throughout its shelf life. If you're looking for other health and wellness products to store safely at home, our vitamins and supplements range is also worth exploring.

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep the cap tightly closed when not in use
  • Keep out of reach and sight of children
  • Do not use after the expiry date printed on the bottle
  • Do not store in the bathroom, where humidity and temperature fluctuations can affect the product

Frequently Asked Questions

Where can I buy Bio-Oil Skincare Oil online in the UK?

You can buy Bio-Oil Skincare Oil directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, with fast delivery to your door. It is available without a prescription and is classed as a general sale product. No consultation is required to order.

How does Bio-Oil Skincare Oil work on scars?

Bio-Oil contains PurCellin Oil, which reduces the viscosity of the formula so that vitamins A and E, along with plant extracts, can penetrate the upper layers of the skin more effectively. Regular massage during application also helps to soften and flatten scar tissue over time. Results are gradual and typically become visible after consistent use for at least three months.

How do I use Bio-Oil Skincare Oil step by step?

Start with clean, dry skin and apply a few drops of Bio-Oil to the affected area. Massage in small circular motions for at least two minutes to encourage absorption. Use twice daily — morning and evening — for a minimum of three months to see the best results.

When is the best time to apply Bio-Oil?

Bio-Oil works best when applied twice daily — once in the morning and once before bed. Applying it to slightly damp skin after a shower can help the oil absorb more easily. Consistency matters far more than timing, so building it into your daily routine is the most important step.

Can Bio-Oil cause any side effects?

Bio-Oil is generally well tolerated, but some people may experience mild skin irritation, redness, or an allergic reaction to one of its plant-based ingredients such as lavender or chamomile oil. A patch test on a small area of skin 24 hours before first use is strongly recommended. If you notice significant itching, swelling, or a rash, stop using the product and speak to your pharmacist.

Is Bio-Oil safe to use during pregnancy?

Bio-Oil is widely used during pregnancy to help reduce the appearance of stretch marks, and many midwives are familiar with it. However, you should always speak to your midwife or GP before introducing any new skincare product during pregnancy, particularly in the first trimester. The NHS advises keeping skin moisturised during pregnancy, though no topical product can guarantee prevention of stretch marks.

How long does it take for Bio-Oil to work on stretch marks?

Most people begin to notice a visible improvement in stretch marks after around three months of consistent twice-daily use. Newer, red or purple stretch marks tend to respond more quickly than older, silvery-white ones. Patience and regularity are key — skipping applications will slow progress.

What are the alternatives to Bio-Oil for scars and stretch marks?

Alternatives include silicone gel sheets (particularly effective for raised or hypertrophic scars), cocoa butter-based creams, and rosehip oil. You can explore a range of options in our skin care collection at Cured Pharmacy. Your pharmacist can help you decide which product is most appropriate for your specific skin concern.

Is Bio-Oil suitable for use on the face?

Yes, Bio-Oil can be used on the face to address uneven skin tone, dry patches, or facial scarring. However, people with oily or acne-prone skin should use it with caution, as oil-based products can occasionally contribute to blocked pores. Apply a small amount and monitor your skin's response over the first few days.

Can children use Bio-Oil Skincare Oil?

Bio-Oil is generally considered suitable for children over the age of 2, but you should always consult a GP or pharmacist before using it on young children. It should not be applied near the eyes, mouth, or on broken skin. Keep the product out of reach of children at all times.

How long can you use Bio-Oil for?

Bio-Oil can be used long term as part of a regular skincare routine, and there is no defined maximum duration of use. Many people continue using it beyond the initial three-month treatment period to maintain skin hydration and texture. If you have any concerns about prolonged use, speak to your pharmacist or GP.

Does Bio-Oil help with dry heels?

Yes, Bio-Oil can be applied to dry, cracked heels to help soften and hydrate the skin. Massage a few drops into the heel area and cover with socks overnight for a more intensive treatment. For more targeted foot care products, you can also browse our foot care range at Cured Pharmacy.

What does the research say about Bio-Oil for stretch marks?

Clinical studies conducted by the manufacturer have shown improvements in the appearance of stretch marks with consistent use, though independent peer-reviewed evidence is more limited. The NHS acknowledges that no topical treatment can completely remove stretch marks, but moisturising oils and creams may help improve their appearance over time. Always approach marketing claims with a degree of scepticism and set realistic expectations.

Can I use Bio-Oil alongside other skincare products?

In most cases, yes — Bio-Oil can be incorporated into an existing skincare routine. However, if you are using prescription topical treatments such as retinoids or corticosteroids on the same area of skin, speak to your pharmacist before combining products. Applying Bio-Oil after other products have been absorbed is generally the safest approach.

Is Bio-Oil vegan and cruelty-free?

Bio-Oil's standard Skincare Oil formulation contains PurCellin Oil, which is a synthetic ingredient, but the product is not certified vegan by all standards — you should check the current product labelling or the manufacturer's website for the most up-to-date information. Bio-Oil does offer a separate vegan-certified formulation. If vegan skincare is important to you, check our vegan product range for suitable alternatives.

How Should You Use Bio-Oil Skincare Oil?

Using Bio-Oil correctly makes a real difference to the results you'll see. It's not enough to simply apply it and hope for the best — the technique matters. Always start with clean, dry skin to ensure the oil can absorb properly rather than sitting on top of surface dirt or other products.

What Is the Correct Dose of Bio-Oil Skincare Oil?

There is no fixed "dose" for Bio-Oil in the way there is for oral medicines, but the amount you use and how often you apply it does matter. Using too little may reduce effectiveness, while using too much can leave the skin feeling greasy and may not improve results. The table below gives a general guide based on the indication and age group.

When Is the Best Time to Use Bio-Oil Skincare Oil?

The most effective approach is to apply Bio-Oil twice daily — once in the morning and once in the evening before bed. Some people find that applying it to slightly damp skin immediately after a shower helps the oil absorb more readily, as the skin's pores are more open at this point. The key is building it into a routine you can stick to consistently, because regularity matters far more than the precise time of day.

If you're using Bio-Oil on the face, applying it as the last step in your evening skincare routine — after any serums or treatments — tends to work well. In the morning, allow it to absorb fully before applying SPF or makeup on top.

How Long Can You Use Bio-Oil Skincare Oil For?

Bio-Oil can be used long term without a defined maximum duration. For scars and stretch marks, the manufacturer recommends a minimum of three months of consistent use before assessing results. Some people continue using it indefinitely as a daily moisturiser or to maintain improvements already achieved. There is no evidence to suggest that prolonged use causes harm, provided you have no adverse reaction to the ingredients.

If you are using Bio-Oil during pregnancy, continue use throughout the pregnancy and into the postpartum period if you wish to address any stretch marks that have developed. Always speak to your GP or midwife if you have any concerns about long-term use during or after pregnancy.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Bio-Oil Skincare Oil?

Bio-Oil is generally well tolerated by most people, and serious side effects are uncommon. That said, because it contains several plant-derived ingredients, there is always a possibility of a skin reaction — particularly if you have sensitive or reactive skin. The most frequently reported issues are mild and tend to resolve quickly once you stop using the product or reduce the amount applied.

  • Mild skin irritation or redness at the site of application
  • A temporary warm or flushed sensation after massage
  • Greasy or heavy feeling on the skin if too much product is used
  • Slight shininess or residue if not fully absorbed before dressing

What Are the Less Common Side Effects of Bio-Oil Skincare Oil?

Less commonly, some individuals may experience a more pronounced reaction, particularly those with a known sensitivity to fragrance or plant-based ingredients. If you have a history of contact dermatitis or eczema, you should be especially cautious and always perform a patch test before applying Bio-Oil to a larger area of skin.

  • Allergic contact dermatitis — presenting as itching, a raised rash, or blistering
  • Worsening of acne or comedones (blocked pores) in acne-prone individuals
  • Photosensitivity in rare cases — some plant extracts can increase the skin's sensitivity to UV light
  • Stinging or burning sensation, particularly on skin that is thin or recently healed

What Are the Serious Side Effects of Bio-Oil Skincare Oil?

Serious side effects from topical use of Bio-Oil are rare but not impossible. A severe allergic reaction (anaphylaxis) is extremely unlikely with a topical product, but localised severe reactions can occur. If you notice significant swelling, widespread hives, difficulty breathing, or a rapidly spreading rash after applying Bio-Oil, stop use immediately and seek urgent medical attention. Do not wait to see if the reaction settles on its own in these circumstances.

What Should You Do If You Experience Side Effects of Bio-Oil Skincare Oil?

For mild reactions such as redness or irritation, simply stop applying Bio-Oil to the affected area and allow the skin to settle. Rinsing the area with cool water may help. If the reaction is more significant — such as a spreading rash, blistering, or persistent swelling — contact your GP or pharmacist promptly. They can advise whether you need further treatment and whether an alternative product might be more suitable for your skin type.

Always mention any new skincare products you are using when speaking to a healthcare professional about a skin reaction, as this helps them identify the likely cause more quickly.

Can Bio-Oil Skincare Oil Interact With Other Medicines?

No clinically significant drug interactions have been identified for Bio-Oil when used topically as directed. However, if you are currently using prescription topical treatments — such as corticosteroids, retinoids, or antibiotic creams — on the same area of skin, it is worth speaking to your pharmacist before combining products. Layering multiple topical products can sometimes affect absorption or increase the risk of irritation, particularly on sensitive or compromised skin.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
