There are many ways to lighten melanin spots. Here are some suggestions:

1. Sun protection: Use sunscreen daily, choose products with high SPF values, and avoid sun exposure. Stimulates the skin and prevents melanin production. Especially within 15 minutes before going out, apply sunscreen evenly to exposed skin and reapply regularly.

2. Spot lightening products: Choose products that can effectively lighten melanin, such as vitamin C, enzymes, fruit acids, etc. These ingredients can inhibit the activity of tyrosinase, reduce the synthesis of melanin, and achieve the effect of lightening spots.

3. Exfoliation: Regular and appropriate exfoliation care can remove aged cuticles and accumulations on the skin surface, promote metabolism and cell regeneration, and help fade spots.

4. Whitening mask: Using a mask with whitening effect, such as a mask containing arbutin, glycyrrhizic acid and other ingredients, can help reduce melanin deposition and make the skin more even.

5. Cosmetic concealer: Choose a concealer product suitable for your skin tone, which can temporarily cover spots during the makeup process and make the skin look more even.

6. Pay attention to skin care: Maintaining good skin care habits, such as regular cleansing, hydration, moisturizing, etc., can help improve skin condition and reduce the possibility of melanin pigmentation. Also avoid using irritating skin care products.

It should be noted that spot lightening is a long-term process, and you need to insist on using products and methods suitable for your skin condition to achieve results. If the spots are severe or cannot fade on their own, it is recommended to seek advice from a professional dermatologist or beautician.
