If your cesarean scar is red and the skin is flaking, it is likely because the skin is still healing and is more sensitive. Using a fragrance-free moisturizer regularly, about 2-3 times a day for several weeks, should help improve the appearance and feel of the scar. Avoid using scented products and soaps, and gently pat dry the skin after bathing or showering before applying the moisturizer. This should help promote healing and improve the condition of the scar over time.
