The application of topical ascorbic acid preparations, commonly known as vitamin C serums, to the face before sleep involves a specific process to maximize its potential benefits and minimize potential irritation. This process generally includes cleansing the skin, applying the serum, and subsequently moisturizing. The timing of this application, specifically at night, is often recommended due to considerations regarding sunlight exposure and potential interactions with other skincare ingredients.
Employing a vitamin C serum as part of a nighttime skincare regimen can offer several advantages. Vitamin C is known for its antioxidant properties, which can aid in neutralizing free radicals accumulated throughout the day. Furthermore, it plays a role in collagen synthesis, potentially contributing to skin firmness and elasticity over time. Historically, vitamin C’s role in maintaining skin health has been recognized, though its widespread incorporation into skincare products is a more recent development.
