UVA rays are the primary cause of UV induced premature skin ageing, and penetrate deep beneath the skin\'s surface, reaching the dermis. The elastin fibre network, the skin\'s \"springs\", begins to weaken. Skin becomes less firm and wrinkles appear more pronounced. UVA rays can also travel through glass, so even when you are indoors, your skin is likely to be exposed to the premature ageing effects of UVA rays. The L\'Oréal Paris Expertise: Advanced protection against ageing: Elast-flex: an exclusive technology stimulates and reinforces the elastin support network. The formula improves skin firmness and the ability to bounce back. Pro-Retinol A: a powerful anti-wrinkle ingredient known to stimulate skin cell renewal*. Wrinkles are visibly reduced and skin texture appears more even and refined. SPF30: broad spectrum filter system to protect against harmful UVB rays, and from UVA rays responsible for premature skin ageing and dark spots. The light non-greasy texture absorbs easily leaving your skin beautifully moisturised and hydrated. Used daily, the broad spectrum UV protection helps guard your skin against then sun\'s most damaging rays. Reveal firmer, more refined, younger looking skin.
