How long will it take for Cui Shi Park to be effective and will it rebound?

I have used Pu Cui Shi for freckle removal for two years, but it has not rebounded, especially the essence inside. There are two things, one is fading. One brightens the skin tone, and the skin is much better after use.

What women fear most is getting old and fat. Fat can be saved by fitness, but it is really hard to change when you are old! Once a person is old, it is inevitable that there will be all kinds of skin troubles, such as decrees, heads, crow's feet, long spots on his face and dark yellow face.

Today we will talk about the problem of long spots on the face.

Distinguish chloasma from freckles

Female friends will gradually turn yellow and dark with age, and many will have yellowish brown patches on their cheeks or cheekbones. This spot is actually the so-called chloasma.

Freckles are small dark brown spots on the face. They usually have skin lesions around the age of 5, which tend to get worse before and after puberty. It is a light brown or dark brown punctate pigmentation spot, round, oval or irregular, with clear boundaries. There are still some differences between the two.

1, for different reasons.

(Chloasma): genetic susceptibility, sunlight exposure and changes in sex hormone levels are yellow.

(Freckle): The cause of freckles is mainly related to autosomal dominant inheritance. People with freckle genetic factors are also prone to freckles once they are stimulated by the outside world, such as sun exposure and dry skin.

2. The characteristics of skin lesions are different.

(chloasma): Skin lesions exist symmetrically; It is yellow-brown; Most of them exist in flake form.

(Freckles): Skin lesions are mostly located on cheeks and bridge of nose; Brown or light brown; Most of them exist in the form of spots or sesame seeds.

Improper use of sunscreen.

It is easier to grow spots.

As the weather gets hotter, the importance of sun protection becomes more and more prominent! But some "pits" must be avoided. If you don't apply sunscreen in the right way, chloasma may form in the long run.

1, insufficient dose

How many people can't use up the sunscreen in one year, and ask if they can continue to use the expired sunscreen in the second year.

According to the international standards for human testing of sunscreen, the correct dosage is about 2 mg/cm. , applied to the face, with the common mask size of 24cm x 20cm as a reference, you need to apply about 1g sunscreen (coin size) each time.

2. Apply sunscreen before going out.

Why is it recommended to apply sunscreen 0/5 ~ 30 minutes before going out? Because sunscreen needs time to form a film to play the role of sunscreen and waterproof. If you apply sunscreen before going out or after going out, ultraviolet rays can easily penetrate the sunscreen film, and sweating can easily damage the sunscreen film.

If you have the habit of making up, apply sunscreen for 3 to 5 minutes before making up.

3, random smear

Proper application techniques can make the sunscreen film evenly coated on the face, and at the same time, it will improve the bad skin feeling such as greasy and whitening.

Unlike skin care products that need to be massaged back and forth on the face to promote absorption, sunscreen should be gently and evenly applied in one direction, usually using the "four-finger application method". That is to say, use four fingers to straighten and close together, gently and evenly apply in one direction, so that sunscreen products stay more in the elevation of the skin bulge.

4, did not touch up the paint in time

Due to sweating, self-degradation of sunscreen components, continuous reaction with ultraviolet rays and other reasons, the sunscreen effect of sunscreen is getting weaker and weaker with the passage of time, so it is necessary to apply it in time. Like outdoor light intensity, chemical sunscreen generally needs to be replenished every 2 to 3 hours, and physical sunscreen generally needs to be replenished every 3 to 4 hours. If you sweat too much when swimming, you have to apply it immediately.

5. No suitable sunscreen was selected.

Different scenes need to choose different sunscreen signs such as SPF value and PA value. If you use low-magnification sunscreen for daily commuting under long-term exposure, you will naturally get sunburned.

"Ten spots and nine withered spots, long withered spots"?

There is a concept called "ten spots and nine dry spots. If you work for a long time, you will have spots."

Now many girls are talking about their dry skin and oily skin. In fact, friends with dry skin should pay more attention to the usual hydration and sun protection. Long-term drying is easy to form spots.

Dry skin means that the skin is fine and thin, the pores are not obvious, the sebum secretion is small and even, and there is no greasy feeling. The skin is dry and looks clean, delicate and beautiful. The moisture content of cuticle is lower than 10%, and sebum secretion is less, wrinkled and dull. Sensitive to external stimuli, skin is prone to erythema, and its PH value is about 5.5-6.0.

Method of judging skin quality: You can test your face when you get up in the morning. You don't have to wash your face, but touch the skin on your cheeks, forehead, nose and chin with your hands. We can touch different parts with different fingers, such as the forefinger touching the cheek and the middle finger touching the forehead. To feel the state of your face at this time.

One possibility is finger oil (big oil field)-oily skin;

One possibility is that there is a little oil and there is no dry feeling on the face-neutral skin;

Another possibility is that there is no oil at all, but it feels dry, hot and even desquamate (peeling)-dry skin;

Of course, it is also possible that your different fingers have different feelings. Some places may be "big oil fields", and some places are relatively dry. -Mixed skin.
