Its whitening mechanism involves blocking the pro-melanin-producing signals sent by Keratinocytes to Melanocytes, inhibiting melanin production at the upstream source, and simultaneously reducing UV-induced hyperpigmentation. It shows significant improvement in sun spots, post-inflammatory hyperpigmentation (PIH), and overall uneven skin tone, while being much gentler than traditional Kojic Acid.\u003c\/p\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003e\u003cstrong\u003e② Glycolic Acid — Accelerates old pigment metabolism for faster brightening results\u003c\/strong\u003e\u003cbr\u003eGlycolic Acid is the smallest molecular weight AHA (Alpha Hydroxy Acid), effectively promoting stratum corneum renewal, accelerating the metabolism and shedding of dead skin cells containing old pigment, and also speeding up the epidermal cell renewal cycle, allowing the skin to quickly appear renewed and radiant.
