    Diminished pigmentation spots, restored skin integrity and suppleness, and hydration are some benefits provided by the vitamin C serum containing 10% ethyl ascorbic acid and 0.5% ferulic acid. By obstructing tyrosinase enzyme activity and hindering melanogenesis, Ethyl ascorbic acid brightens pigmentation spots, prevents their formation, and repairs UV-induced damage. [1] The suppression of cytotoxic and inflammation-related enzyme production, such as cyclooxygenase, is one of how ferulic acid helps achieve its anti-inflammatory and antioxidant effects [2]. The signs of aging are reduced by Arginine's synthesis stimulation and its ability to moisturize the skin, as stated in [4]. For all skin types, particularly those that are mature, pigmented, or dull, this serum is a great choice due to its unique and simple composition. This exceptional product will undoubtedly leave an impression.

    Scientific validity

    To promote collagen synthesis, prevent DNA damage and provide exceptional skin brightening and pigment spot reduction, the product contains ethyl ascorbic acid, a novel form of vitamin C.

    The hydrophilic and lipophilic properties of ethyl ascorbic acid make it a stable form of vitamin C that metabolizes into pure vitamin C. This ingredient has superior penetration abilities, compared to other forms of vitamin C, and is stable in a wide range of temperatures, remaining photostable. Over time, the color and scent of products including ethyl ascorbic acid remain unaltered.

    Ethyl ascorbic acid's skin benefits consist of safeguarding DNA from free radical injury, serving as an antioxidant, shielding from photoaging, and restricting tyrosinase enzyme activity. Additionally, it is capable of stimulating collagen production and reducing pigmentation spots.

    The multi-functional Ferulic acid possesses anti-inflammatory, antioxidant, and antimicrobial properties. By effectively neutralizing free radicals and blocking enzyme activity related to their formation, ferulic acid protects important skin structures, such as keratinocytes, fibroblasts, collagen, and elastin. Moreover, ferulic acid obstructs melanogenesis, augments angiogenesis, and hastens wound healing, establishing it as an efficient photoprotective and skin-whitening agent.

    Amino acids

    Conditioning hair and moisturizing skin are two benefits that come from amino acids, commonly used in skincare products. The presence of arginine in the human body is responsible for moisturizing skin and increasing collagen synthesis. Its ability to reduce signs of aging makes it a valuable addition to skincare formulas.
