EQQUALBERRY Vitamin Illuminating Serum is formulated with 4% Niacinamide and a brightening Vitamin C complex, complemented by Hyaluronic Acid and Vitamin E. This water-light serum targets visible dark spots and uneven skin tone while supporting a more uniform complexion. The inclusion of Hyaluronic Acid aids in maintaining skin hydration levels, while Vitamin E provides additional antioxidant support.

Suitable for daily use on most skin types, including sensitive and combination skin, the serum is designed to layer comfortably under moisturizer or sunscreen without a sticky feel. As a Korean skincare product, it emphasizes a gentle yet effective approach to radiance, relying on ingredients known for their brightening and moisturizing properties. The 1.01 fl. oz (30 ml) bottle is sized for consistent use over several weeks.

The formula is free from artificial fragrances and harsh additives, aligning with clean beauty standards. It can be applied both morning and evening after cleansing and toning, then followed by a suitable moisturizer. Those concerned with pigmentation issues from sun exposure or aging may find this a practical addition to their routine.

The serum works by gradually improving clarity and evenness over time, without immediate drastic changes. It is best suited for individuals seeking a mild, hydrating brightening solution that can be integrated into an existing regimen. The combination of Niacinamide, stabilized Vitamin C, and moisturizing elements makes it a versatile option for daytime protection against environmental stressors and nighttime recovery. No exaggerated claims are made regarding results, as individual experiences vary.
