This overnight treatment gel targets the hyperpigmentation (pink/red marks) left behind after inflammatory acne, otherwise known as 'post-inflammatory erythema'. The advanced formula contains: glycolic acid (5%) and salyclic acid (2%), which dissolve the cells on the skin's surface, artificially speeding up cell turnover to reveal the fresh new layers underneath, unifying the skin's tone and smoothing its surface; niacinamide (5%), which is famed for its hyperpigmentation-fighting properties; ectoine (1%), an amino acid that boosts the skin's hydration levels and elasticity, and stenghtens the skin's barrier; and Luminia Granatum (0.3%), an advanced multi-step active ingredient derived from pomegranate that fights against pigmentation imperfections.
