Dermalogica's #1 serum worldwide now comes in a larger size with an added saving!Your skin endures a lot. Every day, natural and environmental triggers work to change skin from inside and out - speeding up the ageing process and resulting in hyperpigmentation, fine lines, wrinkles and a loss of elasticity. Skin can fight back against these processes, but it needs help. Antioxidants like Vitamin C help the skin defend itself against stressors by neutralising damaging molecules. However,Vitamin C can actually enhance the skin's natural defense system, enabling it to defend itself from oxidative stress. Many topical Vitamin C products contain unstable ingredients that lose efficacy before they've been applied to the skin.BioLumin-C Serum combines an ultra-stable Vitamin C complex with advanced bio-technology to deliver the natural power of Vitamin C where it's needed most. BioLumin-C does more than simply brighten, firm and reduce the appearance of fine lines; it works with skin's own defenses, giving you brighter skin from within.
