1, protect yourself from the sun. 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 apply sunscreen in advance. When the sun is strong, you should take an umbrella to prevent ultraviolet rays, or wear 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 are ready for sun protection, there are always omissions. At this time, you need to go home to repair after drying. 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 shine after makeup, but the price behind this beauty is the decline of skin quality. Infiltrated heavy metals can also induce and aggravate the deposition of melanin in deep skin, making spots more and more obvious. So, try not to wear makeup. When it is unavoidable, you must remember to remove makeup carefully.

4. Eat more beauty food. Many foods are good for nourishing the skin. For example, tomatoes contain glutathione that can inhibit melanin, carrots are rich in carotene that can scavenge free radicals and resist oxidation, and vitamins C and E are 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. Here is a natural and convenient skin care product, which is potato. Slice raw potatoes and apply them to freckled areas to dilute the spots.

6. 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, and give the skin enough time to rest and repair itself.

7. Drink red wine in moderation. Red wine helps to remove free radicals, resist cell oxidation, promote blood circulation, and beauty beauty plays a great role in reducing pigmentation and rejuvenating skin.
