1, do a good job of sun protection. Ultraviolet rays in the sun are one of the causes of freckles, which make the latent melanin active and slowly turn into small spots. Before going out, you should put on sunscreen in advance. When the sun is strong, you should hold an umbrella to prevent ultraviolet rays, or put on a sun hat to block the sun from shining on your face as much as possible.

2. Don't neglect post-sun repair. Although we have made preparations for sun protection, there are always omissions. At this time, we need to go home and repair after sun exposure. In addition to applying repair cream, remember to replenish moisture to facial skin.

3. Use less cosmetics. Cosmetics contain heavy metals such as mercury, lead and arsenic, which can make you dazzling after makeup, but the price behind this beauty is the declining skin quality. Infiltrated heavy metals can also induce and aggravate the deposition of melanin in deep skin, making spots more and more obvious. Therefore, try not to put on makeup. In unavoidable situations, you must remember to remove makeup carefully.

4. Eat more beauty food. Many foods are beneficial for nourishing skin. For example, tomatoes contain glutathione which can inhibit melanin, carrots are rich in carotene which can scavenge free radicals and resist oxidation, and vitamins C and E are all good helpers for beauty.

5. Use natural skin care products. Many industrial elements are added to the freckle products produced by manufacturers, which have many side effects after long-term use. You can choose natural freckle products, which are safer and more effective.

6, potato chips are light spots. Cut raw potatoes into thin slices and apply them to the spots to dilute the spots.

7. Ensure the quality of sleep. Frequent staying up late and lack of sleep will accelerate skin aging and aggravate melanin deposition. Form a scientific and reasonable schedule, ensure eight hours of sleep, so that the skin can have enough time to rest and repair itself.

8. Drink red wine in moderation. Red wine can help remove free radicals, resist cell oxidation, and promote blood circulation and beauty, which plays a great role in reducing pigmentation and rejuvenating skin.
