How It Works

Powered by next-generation brightening actives, Concentrated Brightening Serum targets both the formation and appearance of hyperpigmentation at a cellular level. Actizyme® gently accelerates skin renewal, allowing Brighlette® to work deep within the skin to regulate melanin production and interrupt the overactive pigmentation process. This intelligent marine biotechnology helps normalise skin’s pigment pathway, reducing the appearance of dark spots while preventing new discolouration from forming. Flashwhite Unispheres™ enhance surface luminosity with optical brighteners that instantly revive dull skin, leaving the it smoother, more radiant and beautifully even intone.

FAQs

Pigmentation forms when the skin produces excess melanin often triggered by sun exposure, hormones, heat or inflammation. Over time this creates dark spots, different forms of hyperpigmentation and general unevenness across the complexion.

Brightening serums like Concentrated Brightening Serum use actives such as Brighlette® and Actizyme® to regulate melanin production and accelerate cell renewal. This helps fade visible discolouration while promoting a clearer, more luminous skin tone.

Visible improvement can often be seen within 2–4 weeks, with optimal clarity achieved after consistent use over 8–12 weeks. Remember, hyperpigmentation forms slowly and fading it takes steady, consistent care.
