ISNTREE Hyper Vitamin C 23 Serum is a Korean skincare brightening serum formulated with 23% Pure Vitamin C, Vitamin E, and Panthenol to visibly improve skin tone, enhance radiance, and provide antioxidant protection.

It helps reduce the appearance of dark spots, post-acne marks, hyperpigmentation, and dullness while supporting collagen production and strengthening the skin's moisture barrier. Panthenol helps soothe and hydrate the skin, making the formula more comfortable for regular use.

This lightweight serum absorbs quickly into the skin, leaving it smoother, brighter, and more even-looking without a greasy finish. With consistent use, skin appears healthier, firmer, and naturally glowing.
