Skinstitut's depigmenting serum — combining three evidence-based brightening actives at clinical concentrations. The formula runs stabilized vitamin C (3-O-Ethyl Ascorbic Acid — excellent stability in aqueous formulations), niacinamide (blocks melanosome transfer), and alpha-arbutin (competitive tyrosinase inhibition) for a three-pathway approach to hyperpigmentation. Skinstitut is Australia's professional skincare brand (salon-distributed, aesthetician-recommended) that positions itself at the intersection of clinical efficacy and accessible pricing — think SkinCeuticals philosophy at 1/3 the price. At ~AUD $45 for 30ml, it significantly undercuts comparable multi-active brightening serums from international brands. The brightening serum Australian aestheticians upsell to clients alongside their LED and microneedling treatments.
