Ingredients

Vitamin C neutralizes free radicals and inhibits melanin production for brighter, more protected skin. This focused formula puts all its power behind one proven active for maximum impact.

Vitamin C (L-ascorbic acid) donates electrons to neutralize free radicals before they can damage collagen fibers and DNA. It also inhibits tyrosinase, the enzyme responsible for melanin overproduction, which is why it simultaneously brightens existing discoloration and prevents new spots from forming. The antioxidant effect compounds with sunscreen, providing a second line of defense against UV-induced aging.

About the brand

IOPE is a premium Korean skincare brand built around treatment-inspired formulas for firmness, radiance, texture, and overall skin vitality. This collection brings together the brand's strongest live signals at Protoclinical, including retinol serums, high-strength vitamin C care, Stem III recovery formulas, creams, emulsions, softeners, and skincare sets that make it easier to shop the brand by routine.

The assortment leans clinical and performance-led, with concentrated treatment steps alongside richer moisturizing formats and giftable sets. That mix supports shoppers looking for a more targeted routine instead of a single hero product, whether the focus is smoother-looking texture, brighter tone, or daily age-support care.

Protoclinical recommends IOPE as a structured brand-led protocol: start with softener and emulsion, layer in serum or ampoule, and finish with cream for a routine that stays focused on visible skin quality without overclaiming beyond the live assortment.
