As we age our skin experiences a number of physiological changes such as thinning of the dermis and epidermis as well as a reduction in keratinocytes and collagen production. In addition to natural ageing, the skin is repeatedly exposed to environmental stressors such as UV radiation, pollution etc. Thinning of the dermis and epidermis results in a less effective skin barrier function and in turn leads to higher environmental stressors, higher trans-epidermal water loss and vulnerable skin. Warning – May cause irritation. Skin may also start to shed dead skin cells within the first week and may last a further week. Avoid direct and unprotected exposure to sun. DO NOT use during pregnancy. DIRECTIONS Introduce this serum into a skincare regime gradually. Apply in the evening over serums and under face creams. Keep skin moisturised with hydrating serums or face cream after use.
