Vitamin C (L-ascorbic acid) is an effective antioxidant that protects the skin from free radicals and premature ageing. It can reduce pigmentation and dark spots, stimulate collagen production, promote a more even and radiant skin tone, and support the skin against sun damage. For best results, a serum with 15–20% pure L-ascorbic acid and a low pH is recommended, used in the morning under sun protection. With consistent use, vitamin C can contribute to healthier, more youthful-looking skin.

Dry skin occurs when the skin lacks oil and can’t retain enough moisture, which can lead to tightness, itching, redness, and flaking. Causes can include climate, age, harsh cleansing products, hot water, sun damage, or skin conditions. To restore the skin’s balance, a gentle cleanser, a rich moisturizer with ingredients like ceramides or hyaluronic acid, serum, sun protection, and limiting hot water are recommended. A healthy diet with omega-3 and vitamins C and E can also support the skin from within. With the right and consistent care, dry skin can improve significantly.
