How much does daily sunscreen use help with melanin deposition?

Generally speaking, daily sun protection has a significant effect in preventing melanin deposition and is an important measure for preventing hyperpigmentation. The analysis is as follows:

Ultraviolet (UV) radiation is the primary cause of melanin deposition. When the skin is exposed to UV light, melanocytes become overly active, producing large amounts of melanin to protect the skin from damage. Prolonged UV exposure can lead to melanin deposition, causing skin problems such as pigmentation spots and sunspots. Therefore, sun protection can reduce UV-induced skin damage, thereby lowering the risk of melanin hyperpigmentation.

Using sunscreen, umbrellas, sunglasses, and other sun protection measures can effectively block the harmful effects of UVA and UVB rays on the skin, thus reducing the risk of melanin deposition. Additionally, long-term sun protection helps maintain healthy skin and reduces UV-induced skin aging, wrinkles, and other issues.

Besides daily sun protection, maintaining skin hydration is also important. Adequate moisture helps reduce melanin production. It is recommended to drink plenty of water and use moisturizing lotions and creams to maintain skin hydration. If necessary, you can also visit a hospital for improvement through photorejuvenation treatments. This method uses light of specific wavelengths to act on the skin, stimulating collagen regeneration and improving skin texture.The general reference price for photorejuvenation is 2000-4000 yuan per session, with noticeable improvement typically seen after 3-5 sessions, although mild discomfort may occur.
