Key Ingredients & Benefits

This brightening serum harnesses the power of two key ingredients: 25% pure Vitamin C and 1,000ppm Glutathione. The high concentration of Vitamin C helps brighten skin and fade dark spots, while Glutathione acts as a potent antioxidant that protects the skin from oxidative damage. Additionally, the serum contains 0.1% PHA, a mild exfoliant that removes dead skin cells, enhancing texture and radiance. Together, these ingredients work synergistically to improve skin elasticity and hydration, leaving you with smoother, more youthful-looking skin.

Best For

This skincare treatment is ideal for those struggling with uneven skin tone or persistent dark spots. It is also a great choice for individuals seeking an anti-aging serum to help with fine lines and improve overall skin texture. People with combination, dry, or normal skin types will benefit the most from this serum, as it hydrates while gently exfoliating. Additionally, if you're a fan of Korean skincare or prefer products from reputable brands, this serum offers both efficacy and trustworthiness for your skincare routine.
