Why does skin need oil?

The simple truth is that our skin is made-up mostly of water, and to keep our skin from losing moisture we need oil. Because oil locks in moisture to help skin function. Moisture facilitates enzyme activity in the skin, and enzyme activity is responsible for healthy skin activity – everything from what skin looks and feels like, to how it repairs and regenerates itself, and even to its strength and resilience.

Skin by design loves oil, and has its own natural outer oily layer to lock in moisture; the problem is that everyday exposure to the elements and daily washing strips away skin’s protective oily layer allowing moisture to escape. And because skin’s moisture comes from within, lost moisture simply cannot be replaced by applying moisture onto the skin.

What can I do to care for my skin?

The first step in caring for skin is to stop it losing moisture. And the best way to do this is by supplementing skin’s natural oily layer by using oil in everyday skincare. Oil mimics skin’s natural oils, so when oils are applied to the skin, they are easily absorbed and assist in effectively nourishing, restoring and protecting skin’s own natural outer oily layer.

What products are in the Bio-Oil range?

Rooted in science and inspired by nature, each product in the Bio-Oil range is clinically proven and designed to effectively work with the skin to deliver optimal skin health. The range consists of Bio-Oil Skincare Oil and Bio-Oil Skincare Oil (Natural) for scars and stretch marks and Bio-Oil Body Lotion and Bio-Oil Dry Skin Gel for dry to extremely dry skin.

What products should I use for scars and stretch marks?

Bio-Oil Skincare Oil: The world's leading scar and stretch mark product.

Bio-Oil Skincare Oil (Natural): 100% natural formulation with clinically proven results.

What products should I use for dry to very dry skin?

Bio-Oil Body Lotion: An ultralight high-oil lotion for everyday moisturization.

Bio-Oil Dry Skin Gel: A revolutionary gelled-oil for intense, long lasting moisturization.

Are all products dermatologically tested?

Yes. All Bio-Oil products are dermatologically tested and are suitable for all skin types.

Can Bio-Oil products be used on babies?

Bio-Oil was not originally designed for use on infants and has not been tested on children. As a precautionary measure, we therefore recommend that it is only used on children of two years of age or older. In the first two years after birth, many changes take place in the human body, including the development of the immune system. Even though the fragrance level in Bio-Oil’s products is very low (0.2%) and the essential oils contained in the product are of very low concentration, young babies are very sensitive.

Bio-Oil contains no preservatives, is dermatologically tested, hypo-allergenic, non-acnegenic and suitable for all skin types. However, we always recommend new users do a patch test as results can vary from individual to individual. This means applying a small amount of the product on the inside of your child’s forearm and leaving it for 24 hrs. Should no reaction develop, you can continue to use it. The product should be applied with care and should not be used near the eyes or mouth.

Are Bio-Oil products tested on animals?

No. None of the Bio-Oil products, or any of their ingredients, are tested on animals by either Bio-Oil or any of its raw material suppliers.

Are Bio-Oil products suitable for vegans?

All products are vegan aside from DSG which contains lanolin.

Are Bio-Oil products packaged in recyclable packaging?

Yes. All Bio-Oil products are packaged in recyclable materials.

Are Bio-Oil products Halaal certified?

Yes. Bio‑Oil products are Halaal certified by the South African National Halaal Authority (SANHA).

Are Bio-Oil products Kosher certified?

Yes. Bio‑Oil products are Kosher certified under the supervision of the Cape Beth Din, Cape Town, South Africa.

Why don't Bio-Oil products show an expiry date?

Bio-Oil products comply with the 7th Amendment of the European Cosmetic Directive which specifies that products that last for 36 months or more do not require a best before date. Three-year-retention samples of Bio-Oil products were tested and showed no deterioration in colour, density, clarity, odour or viscosity. A best before date is therefore not needed. However, Bio-Oil products do have a PAO (open jar) symbol on the packaging so that consumers can feel confident that they can continue to use the product after opening: for Bio-Oil Skincare Oil the period is for up to 36 months and for Bio-Oil Skincare Oil (Natural), Bio-Oil Body Lotion and Bio-Oil Dry Skin Gel for up to 12 months.
