RRP £41 - Broad-spectrum UVA/UVB protection - Diminishes the darkening of existing skin pigmentation - Prevents the occurrence of future pigmentation - Suitable for all skin types experiencing uneven skin tonePROTECT SkinCeuticals Brightening UV Defense SPF 30 PPD 22 (permanent pigment darkening) Also available in an SPF 50 version here Up to 90% of visible aging is caused by sun exposure.* During the pigmentation process, UV radiation upregulates the secretion of calcitonin gene-related peptide (CGRP). An increase in CGRP causes keratinocyte mediators to stimulate the production of tyrosinase, resulting in excess melanin production. Excess melanin forms a protective barrier against solar cellular and DNA damage, resulting in a dull, uneven complexion and unwanted pigmentation in the form of freckles, spots, and melasma. Brightening UV Defense SPF 30 protects skin from the range of UV rays known to cause unwanted pigmentation and accelerated aging. Formulated with HyperBright Complex, a compound targeting hyperpigmentation, this powerful daily-use corrective and protective sunscreen diminishes existing skin discolorations and prevents the occurrence of future pigmentation.
