Whitening sunscreen + repair It is recommended to eat more vegetables and fruits rich in vitamin C, such as tomatoes, lemons, oranges, and kiwifruit, which are also excellent whitening foods. Vitamin C helps to inhibit the formation of melanin and is effective in antioxidant action, which can improve the dull yellow complexion of the skin due to oxidation. Eat more legumes, because the protein contained in legumes is very helpful for the skin to produce collagen, making the skin more delicate and smooth.

Oh, I forgot to bring sunscreen when I was in high school, and when I came back, it was a briquette, and I also summed up some small experiences, I hope it will be useful to you.

I'm red after the sun, remember not to apply some skin care products to your face during this time, it will be redness and pain. After I got home, I used ice and milk to apply my face, and after a few days, I gradually used some skin care products when I was comfortable, I was a student, and I didn't have much money, so I used Nivea's whitening moisturizer all over my body, and I used a bottle of ** really white, everyone said so. I usually drink more milk, take more baths, and use whitening bath liquid, I think Lux and Olay are very good.

That's still about hydrating. Pay attention to sun protection, and rest well, which is also beneficial to **.

It's okay. Rub off the whitening cream.

If you go out less, you can get over in a week.

Hello, glad to have your question

That's because. You may not be wearing enough sunscreen. And the general sunscreen needs to be applied again after 2-3 hours. Don't think wiped it once. It's no problem to go out and bask for a day.

If it's a sunburn. Don't take spot removal products lightly. It can be repaired with the sun.

If it doesn't work, it's never too late to use a spot removal product. Sun protection. Let's use Anesa.

Shiseido. The word of mouth has been good.

Sunscreen is a skincare product that protects against UV rays. Sunscreens have different SPF (SPF), which means that they can avoid sunburn for a longer period of time in a certain situation.

If you use SPF4 sun oil, if you apply 2 mg of sunscreen per square centimeter (about the size of a 10 yuan coin on your face), you can prolong the sunburn time by 4 times, and you can be protected for up to 4 hours if you would have sunburned in one hour**; It is also able to block 75% of UVB (algorithm: (SPF-1) SPF)[1]. The protection factor for UVA is an index that evaluates the sunscreen ability of a sunscreen against UVA, including the Japanese PA value system and the European PPD value system.

Sunscreens act as sun protection through inorganic or organic active ingredients.

Inorganic sunscreen ingredients are usually inorganic substances such as zinc oxide and titanium oxide, which can reflect and scatter ultraviolet radiation; Organic sunscreen ingredients are usually OMC (Octyl Methoxycinnamate) and Oxybenzone (oxybenzone), which absorb ultraviolet radiation and convert the radiant energy into heat. Many sunscreens protect ** from both ultraviolet rays (UVA, UVB) at the same time. UVA and UVB deal different damage to **.

On the other hand, it works through two mechanisms: reflection and absorption of light. Generally, inorganic matter is reflective, and organic matter is absorption.

The most common chemical absorber of ultraviolet rays is PABA (para-aminobenzoic acid), which absorbs UVB. (Note: If you have **sensitivity, you should be cautious about using sunscreens that contain PABA, as PABA can easily cause redness and irritation in sensitive skin.)

Other organic substances that absorb UV rays include:

cinnamic acid (cinnamates), which absorbs UVB;

benzophenones, which absorb UVA;

Proaminobenzoic acid or anthranilates, which absorb both UVA and UVB.

Using sunscreen is not a guarantee that you will not get a tan, so you need to be skillful in applying sunscreen, and remember that sunscreen is not just applied once, and it is generally necessary to reapply sunscreen every 4 hours.

Hello, Know Me Cosmeceutical Skin Consultant is happy to help you.

Ultraviolet rays are divided into long-wave ultraviolet rays, medium-wave ultraviolet rays, short-wave ultraviolet rays, that is, UVA wavelengths 320-400nm, UVB wavelengths 290-320nm, UVC wavelengths 200-290, of which UVC can not reach the ground can be ignored, UVB mainly causes sunburn, UVA mainly causes sunburn and photoaging.

The labeling of sunscreen cosmetics is divided into SPF and PA+, of which the SPF value mainly reflects the blocking of UVB, and the PA+ mainly reflects the blocking of UVA. Therefore, when choosing sunscreens, it is necessary to choose those that have both SPF logo and PA+ logo.

Proper use of sunscreen can effectively prevent damage caused by ultraviolet rays. Generally, it is used 20 minutes before sun exposure, and the amount used must be sufficient, when detecting the SPF value of sunscreen, the amount used is 2mg cm, and in addition, attention should be paid to the loss of sunscreen in time during use, because sun exposure, sweat washing and bathing can cause changes and loss of cosmetics. It is generally accepted that it should be supplemented and updated every 20-30 hours.

It should be applied every two hours and should reach a certain amount.

And if you just put on sunscreen, it won't work right away, so it will take 20 minutes

That's because --- this sunscreen doesn't protect against the sun.

Sunscreen products are generally wiped 30 minutes before going out, and if you just finish wiping and going out, it is equivalent to being exposed to the sun.

Sunscreen only keeps you from getting sunburned, it doesn't prevent you from tanning! No matter what sunscreen you wear, you can't put it in the sun!

The reason why sunscreen gets darker the more you apply it is because you apply sunscreen during these three time periods.

It may be that the amount of coating is not enough, some sunscreen bottles will have a coin-sized circle is the amount of each time, the whole face is a coin size, it is recommended that Bi-soft sunscreen is not oily and moisturizing, and Anexa, KOSE sunscreen spray spray on the limbs and hair, spray 4-5 on one part, and 1-2 hours for recoating when sweating or direct sunlight, and 2-3 hours for recoating indoors.

That's a leak in the sun, the general chemical sunscreen is to achieve sunscreen by decomposing UV, so when the effective substances are used up, naturally there is no sunscreen, so if it has been leaking in the sun, one is to choose PA plus sign more, and the other is to need to reapply once every two hours. Instead of one time in the morning you can manage the whole day.

In the evening, you can use some vitamin A alcohol essence to help with antioxidants (provided you don't have allergies to vitamin A alcohol tolerance).

It needs to be applied evenly, and it may be that there is a problem with the brand.

You use the OLAY Multi-Care Sunscreen, which not only brightens the complexion, but also works with SPF 24-hour dual UVA and UVB protection
