Bio‑Oil helps to prevent the formation and improve the appearance of existing stretch marks formed during pregnancy, teenage growth spurts or periods of rapid weight gain. Keeping the skin moisturized and ensuring the skin maintains its maximum elasticity is the body's best defence against the formation of stretch marks. This can be achieved by keeping the skin well-hydrated and supple at all times.

Bio-Oil's unique formulation combines Vitamins A and E to promote the formation of new collagen, assisting in skin renewal and increasing elasticity. Vitamin E also increases the moisture content of the epidermis, reduces the itch of stretching skin and improves the skin's overall texture and tone.

Bio-Oil's mixture of plant extracts and oils conditions the skin while providing cell regenerative effects. The breakthrough ingredient, PurCellin Oil™, allows for easy absorption of Bio-Oil making the skin soft, smooth and supple.

Treatment of existing stretch marks is most effective on newer formations, although older stretch marks can also show improvement with regular use of Bio‑Oil. Best results are seen after using Bio-Oil twice daily for 3 months.
