P Serum + Kojic Acid (KOJ)

P Serum + Kojic Acid (KOJ) is a personalized serum by Universkin that targets stubborn dark spots, sun damage, and post-inflammatory hyperpigmentation with provider-selected kojic acid concentration. Kojic acid is a powerful tyrosinase inhibitor—it blocks the enzyme responsible for melanin production, making it one of the most effective non-hydroquinone brightening agents available. Available exclusively at RELUXE Med Spa in Westfield and Carmel, Indiana. Dark spots from sun damage, acne scars, and hormonal changes are among the most common complaints our Hamilton County patients bring to RELUXE. Kojic acid provides targeted, measurable lightening of these discolorations without the risks associated with hydroquinone (which can cause paradoxical darkening with long-term use). Your RELUXE provider selects the optimal concentration based on your pigmentation severity and skin sensitivity. For maximum results, kojic acid is often combined with tranexamic acid in the same Universkin serum—creating a dual-pathway formula that addresses pigmentation from two different angles simultaneously.
