Using Vitamin C During Winter

Winter presents a unique set of challenges for the surface of the face, primarily due to the drop in ambient humidity and the increased use of indoor heating. While vitamin C remains a cornerstone of morning skincare, the way it interacts with a compromised moisture barrier changes when the air turns cold.

Transitioning your usage requires focusing on delivery vehicles and timing. Instead of layering multiple active products, shift toward supporting the barrier before and after the application of your chosen antioxidant.

1. Cleanse with lukewarm water. Avoid high-temperature water, which strips natural lipids from the surface. Use a mild, non-foaming cleanser to remove debris from the previous night. Pat the skin with a soft towel until it is barely damp but not dripping.
2. Apply serum to dry skin. If you are using a standard l-ascorbic acid formula, ensure the skin is fully dry to prevent irritation. Dispense three drops into your palm. Press the liquid into the face using flat palms, moving from the center of the face outward.
3. Wait for complete absorption. Allow the product to sit undisturbed for at least three minutes. This prevents the serum from pilling when subsequent layers are added. During this time, the product is setting on the top layer of the skin.
4. Layer a humectant-heavy moisturizer. Winter requires a heavier occlusion. Choose a moisturizer containing ceramides or glycerin to seal the antioxidant. Apply a thick layer to the cheeks and forehead, where dryness is most prevalent.
5. Finalize with protection. Even in winter, ultraviolet exposure persists. Apply a physical sunblock over your moisturizer. Ensure even coverage across the ears and neck to maintain the efficacy of your morning regimen.

Winter demands a shift from high-strength frequency to consistent, protective layering.
