Sun protection tips to help you say goodbye to freckles: Apply sunscreen at the right time

There are many reasons for the formation of freckles, some are caused by genetic genes, hormonal imbalance, slow metabolism, and some are caused by external factors. Ultraviolet rays, stress and poor cleaning habits can all cause freckles.

Sun protection tips to help you say goodbye to freckles

(1) Freckles are inherited genes. Hereditary freckles are divided into dominant and recessive freckles. Dominant freckles begin to appear around the age of 6 to 12 and reach their peak around the age of 18. Most of the hidden spots appear on the face after pregnancy reactions.

(2) Freckles can also be passed down from one generation to the next, which is one of the reasons why some parents do not have freckles but their children have freckles.

(3) Endocrine disorders in pregnant women. After pregnancy, the endocrine system of pregnant women will undergo great changes, which will stimulate hidden freckles to break out.

(4) Emotional instability causes freckles, and the formation of freckles is also closely related to endocrine disorders. For example, bad emotions or feelings, coupled with blood loss caused by monthly menstruation, can easily cause endocrine disorders. Insomnia, irregular diet, and fatigue in life can also cause endocrine disorders.

(5) Frequent exposure to strong sunlight and ultraviolet rays not only accelerates skin aging, but also causes the occurrence of pigmentation such as dark spots and freckles.

(6) Bad cleaning habits can also lead to the formation of freckles. Such as excessive cleaning habits and not paying attention to skin moisturizing.

1. Choose the right sunscreen product

What do SPF and PA stand for? Which degree of sunscreen should I buy?

To put it simply, remember this sentence: "SPF prevents sunburn, PA prevents tanning." SPF can block "UVB" and prevent sunburn and redness, but it cannot prevent tanning. The PA value can effectively protect against "UVA" and prevent skin aging. Many sisters only look at SPF when choosing sunscreen products, but forget the importance of PA value. The more “+” signs there are in PA, the higher its protection against UVA. Generally speaking, PA+ provides protection for about 2 to 4 hours, PA++ provides protection for about 4 to 8 hours, and PA+++ provides protection for more than 8 hours. Therefore, even if you buy SPF50 but it is PA+, you will still get sunburned after three or four hours.

2. Apply sunscreen at the right time

Applying sunscreen is like taking medicine. It will only be effective after it is absorbed by the body. Therefore, the best time to apply sunscreen is 20-30 minutes before going out. And to be effective, you must use enough sunscreen. Don't be stingy, otherwise it will not be worth it. The amount of liquid sunscreen used each time is the size of a dollar, while the amount of cream sunscreen used each time is the size of a soybean.

3. Blind spots cannot be ignored

Think sunscreen only needs to be applied on the face? This is not enough! To achieve the best whitening effect, we need to take 360-degree care of our skin. Certain parts of the body are often neglected, such as the lips, ears, and hairline.

4. Bring all sunscreen products with you when you go outdoors

If you plan to be outdoors for a long time, you must have a sun hat, sunglasses and a parasol. If you want to better block strong ultraviolet rays, you must know how to use these sunscreen products to block a large amount of direct sunlight.

5. Avoid exposure to the sun during the strongest periods of ultraviolet rays

The cooler the place, the lower the ultraviolet rays. For example, at the beach, when you feel the cool sea breeze, the intensity of the ultraviolet rays also reaches its peak. From 11 a.m. to 3 p.m. every day is the time when the ultraviolet rays are the strongest and most lethal. You must avoid outdoor activities at this time.

6. Wash off sunscreen thoroughly

Always wash thoroughly after applying sunscreen! Not washing or not washing thoroughly after applying sunscreen will cause yellowing and spots on the skin! Generally, facial cleansers with strong cleaning properties can clean chemical or physical sunscreens, but facial cleansers with makeup removal function will have a more thorough cleaning effect.

7. Perform post-sun repair in time

The 72 hours after sun exposure is the golden recovery period. The skin becomes fragile after being exposed to ultraviolet rays and needs to be cooled, calmed, hydrated and moisturized. First apply a cold compress to lower the local temperature, and then use an after-sun repair product with anti-inflammatory effects. Skin that has just been sunburned is more fragile, so do not use irritating skin care products in the next few days. Wait until the skin stabilizes before using whitening products. This not only reduces the degree of redness of the skin, but also reduces the formation of melanin.

8. Supplement vitamin C to improve skin quality

In addition to the maintenance of external skin care lotions, healthy skin cells also require internal maintenance. Vitamin C is a natural antioxidant that is essential for creating good skin, because sun exposure will cause cells to produce free radicals and stimulate the formation of melanin. At this time, vitamin C is needed to inhibit melanin and promote the regeneration of collagen. There are many collagen supplements available on the market, but it is recommended to take a small amount first to test the skin reaction. Some people may experience acne-causing side effects, and the effects may vary from person to person depending on their physical condition.

9. Drink tomato juice to prevent freckles

Time magazine in the United States selected tomatoes as one of the "Top 10 Superfoods in the World" because tomatoes are rich in vitamin C. They are known as the warehouse of vitamin C and can effectively reduce the formation of melanin, thereby fading dark spots. Tomatoes have the effect of nourishing the skin and whitening the skin. Drinking a cup of tomato juice at night is very effective in preventing freckles. Since the lycopene in tomatoes will not take effect until 6 to 8 hours after ingestion, it is the perfect time to consume it while you sleep to achieve its excellent whitening effect. However, be careful not to add sugar when eating tomatoes, otherwise the vitamin B in the tomatoes will lose its effectiveness due to the delay in sugar metabolism.

10. Drink lemon juice to whiten and remove spots

Lemon is rich in vitamin C and high concentration of fruit acid, which can whiten, remove spots and anti-aging. Every 100 grams of lemon juice contains 50 mg of vitamin C. In addition, lemon also contains calcium, phosphorus, iron and B vitamins. Drinking lemon juice regularly can not only make your skin white and tender, but also prevent skin blood vessel aging and eliminate facial pigmentation spots.
