This overnight treatment gel targets the hyperpigmentation (pink/red marks) due to an overproduction of melanin following skin inflammation, scarring, hormonal imbalances or exposure to the sun, otherwise known as 'post-inflammatory hyperpigmentation'. The advanced formula contains: Azeloglicina® (5%), a combination of azelaic acid and glycine which inhibits the synthesis of melanin; niacinamide (5%) and tranexamic acid (5%), which fight hyperpigmentation; kojic acid (1%), a safe and effective skin brightener that absorbs into the skin and stops melanin production; and Luminia Granatum (0.3%), an advanced multi-step active ingredient derived from pomegranate that fights against pigmentation imperfections.
