1. You can use whitening skin care products, enhance skin antioxidant capacity, adjust diet, sunscreen and other measures to reduce facial spots.
 2. Stains are caused by melanin deposition. The following measures can be taken to reduce the spots:
 3. 1. Use whitening skin care products. The main effective ingredients in commonly used whitening skin care products are nicotinamide, vitamin C, arbutin, etc. They can play a role in inhibiting the production of melanin, enhancing the skin's metabolic function, accelerating the elimination of melanin, so as to fade the spots and whiten the skin.
 4. 2. Adjust diet. Reduce the intake of fat and sugar in diet, which will lead to oxidation on the skin surface, resulting in poor water retention function of the skin, and the skin is more prone to aging symptoms. Eat more fresh fruits and vegetables, supplement vitamins, and enhance the antioxidant capacity of skin.
 5. 3. Sun protection. The generation of color spots is closely related to ultraviolet rays. Ultraviolet rays destroy epidermal cells, activate tyrosinase, and promote pigment cells to synthesize and secrete melanin. Excess melanin cannot be metabolized, resulting in color spots. Strictly carry out sunscreen work, combine soft sunscreen with hard sunscreen, and reduce the negative impact of ultraviolet rays on the skin.
 6. 4. Adjust work and rest. Good work and rest is conducive to the metabolic function of the skin. Go to bed early and get up early, do not stay up late or stay up late, and ensure adequate sleep.
