Vitamin C is a popular antioxidant ingredient used to help protect the skin from oxidative stress caused by environmental factors such as UV exposure and pollution.
One of the most researched forms is L-ascorbic acid, also known as pure vitamin C. When properly formulated, topical vitamin C can help support collagen production and improve the appearance of uneven pigmentation.
With regular use, a vitamin C serum may help make dull skin appear brighter and reduce the appearance of certain dark spots and post-acne marks.
Vitamin C is commonly used during the morning because its antioxidant properties complement daily sun protection.
A simple routine is:
Cleanser → Vitamin C Serum → Moisturizer → Sunscreen
Remember that vitamin C provides antioxidant support, but it does not replace sunscreen.
