Bio-Oil Natural Skincare Oil - Improve the Appearance of Scars, Stretch Marks and Uneven Skin Tone - 200ml

Is Bio-Oil Good for Scars and Stretch Marks?

Scars and stretch marks are incredibly common. Whether they've appeared after surgery, pregnancy, rapid growth, or weight changes, many people find them a source of self-consciousness. Bio-Oil for scars and stretch marks has been one of the most widely recognised topical skincare oils in the UK for decades, and it's easy to see why. This 200ml bottle gives you a generous supply to use consistently — which, as you'll read below, really does matter when it comes to results. You can explore the full range of topical options in our skin care collection.

Bio-Oil is a non-prescription topical oil containing a blend of plant extracts and vitamins suspended in a lightweight carrier called PurCellin Oil. It's designed to be massaged into the skin twice daily over a sustained period. The NHS notes that keeping skin well moisturised can help improve the appearance of stretch marks over time, and consistent use of a product like this supports that goal.

How Does Bio-Oil Work on Skin?

The key to Bio-Oil's formulation lies in PurCellin Oil, a synthetic analogue of the preening gland oil found in ducks. It acts as a texture modifier — essentially making the overall formula thin enough to absorb into the skin rather than sitting on the surface. This allows the active ingredients to reach the deeper layers of the epidermis where they can have a meaningful effect.

• 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.
• 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 and Chamomile Oils: Plant-derived extracts that contribute to the overall skin-conditioning effect.

Together, these ingredients work to hydrate the skin, support its natural repair processes, and gradually improve the visible appearance of scars, stretch marks, and areas of uneven pigmentation.

Who Should Use Bio-Oil Natural Skincare Oil?

Bio-Oil is suitable for a wide range of people and skin concerns. It's appropriate for use on the body and face, and it's been tested on all skin types. That said, it's worth doing a patch test before applying it to a large area, particularly if you have sensitive skin or a history of allergic reactions to plant-based ingredients.

• People looking to reduce the appearance of surgical or injury-related scars
• Pregnant women wanting to minimise stretch marks (consult your midwife first)
• Those experiencing stretch marks due to rapid growth or weight changes
• Anyone with uneven skin tone, hyperpigmentation, or ageing skin concerns

It is not suitable for use on broken, infected, or inflamed skin. If you have a skin condition such as eczema or psoriasis, speak to your GP or pharmacist before use. You might also find relevant options in our creams and ointments collection if you're managing a diagnosed skin condition alongside your skincare routine.

How Does Bio-Oil Compare to Other Scar Treatments?

Is Bio-Oil Safe to Store and Use Long-Term?

Bio-Oil for scars and stretch marks is generally considered safe for long-term topical use when applied as directed. Store it below 25°C, away from direct sunlight, and keep the cap tightly closed between uses. The 200ml bottle provides a practical supply for a full treatment course — most manufacturers recommend at least three months of twice-daily use to see meaningful results.

Avoid applying near the eyes, mouth, or on broken skin. If you notice any redness, itching, or swelling after application, discontinue use and consult a pharmacist. Vitamin A derivatives are generally considered safe in topical over-the-counter concentrations, but if you are pregnant, it's worth discussing use with your midwife or GP as a precaution.

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

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

Bio-Oil Natural Skincare Oil is a topical cosmetic oil formulated to improve the visible appearance of scars, stretch marks, uneven skin tone, ageing skin, and dehydrated skin. It is not a medicine, but it is a clinically tested skincare product with a long history of use in the UK and internationally. The 200ml size is ideal for those committing to a full treatment course, which typically spans a minimum of three months.

The NHS acknowledges that while no topical product can completely remove stretch marks, keeping skin moisturised and massaging the area regularly may help improve their appearance over time. Bio-Oil supports this approach through its combination of skin-conditioning ingredients and the massage technique recommended during application.

What Do You Need to Know Before Using Bio-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 perform a patch test on a small area of skin 24 hours before first use, particularly if you have sensitive skin or known plant allergies.

Do not use Bio-Oil if:

• You are allergic to any of the listed ingredients, including lavender, chamomile, rosemary, or calendula oils
• The skin in the area is broken, infected, or actively inflamed
• You have an open wound or post-surgical site that has not yet fully healed
• You are applying it near the eyes or mucous membranes

Use with caution if:

• You are pregnant — consult your midwife or GP before use, particularly regarding the Vitamin A content
• You have a diagnosed skin condition such as eczema, psoriasis, or rosacea
• You are using other topical treatments on the same area of skin

Known interactions:

• No clinically significant drug interactions are known for topical use
• Avoid using alongside other retinoid-containing products on the same skin area to prevent potential irritation

How Should You Use Bio-Oil Correctly?

Consistent application is everything with Bio-Oil. Sporadic use is unlikely to produce noticeable results. Follow these steps each time you apply it:

1. Ensure the skin is clean and dry before application.
2. Dispense a small amount of oil onto your fingertips — a few drops is usually sufficient for a localised area.
3. Apply to the affected area and massage in a firm, circular motion for approximately two minutes.
4. Allow the oil to absorb fully before dressing or applying other products.
5. Repeat twice daily — morning and evening — for a minimum of three months.

If you're also managing a skin condition and looking for medicated options, our creams and ointments collection includes a range of clinically appropriate topical treatments.

What Are the Possible Side Effects of Bio-Oil?

Bio-Oil is well tolerated by most people, but as with any product containing plant-derived ingredients, reactions can occasionally occur. Knowing what to look out for helps you use it safely.

Common side effects:

• Mild skin irritation or redness at the application site
• A temporary greasy or oily sensation on the skin
• Mild tingling, particularly on sensitive facial skin

Less common side effects:

• Allergic contact dermatitis — characterised by itching, redness, or a rash
• Photosensitivity in some individuals, particularly with lavender oil content
• Acne flare-ups in those with oily or acne-prone skin, as oils can occasionally block pores

If you experience a severe allergic reaction — including swelling of the face, lips, or throat, or difficulty breathing — seek emergency medical attention immediately. This type of reaction is rare but serious.

How Should You Store Bio-Oil?

Proper storage helps maintain the quality and effectiveness of the product throughout its shelf life. Follow these guidelines:

• Store below 25°C in a cool, dry place
• Keep away from direct sunlight and heat sources
• Always replace the cap tightly after 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 formula
