The five culprit causing dull skin

1, lack of sleep

Too late to sleep or lack of sleep will cause the metabolism to be no longer smooth, causing the aging cuticle to thicken, the skin loses its transparency, and it has a grayish dark color. Even if it is covered with more vivid makeup, it can't hide the dullness of the complexion. To evenly shine the skin tone, or sleep at 11 o'clock every night.

2, pressure

When you are over-tired, your skin's metabolism is slow, and your complexion becomes darker due to the accumulation of keratin. If the skin is dry, the stratum corneum is not rich in water, and the dark complexion and lack of transparency will be more serious.

3, smoking

Smoking causes the microvessels to contract, which causes the blood circulation to deteriorate, and the skin is therefore in an oxygen-deficient state. The natural color of the face is dim and the cigarettes will destroy vitamin C. Vitamin C has the effect of inhibiting melanin and helping the skin to renew, which is very important for skin health. In addition, smoking smoke can also stain the pores and make the complexion dull.

4, cleansing is not complete

When the foundation stays on the skin for a while, it will mix with sebum and dust to form dirt, which will then oxidize and deteriorate. If the cleansing is not thorough, the dirt will remain on the face and the complexion will be dull. The most secreted nasal position of the cortex is the most important place to pay attention, and the problem is even more serious when the pores on the nose are attached to dirt. On the other hand, when the oxidized foundation continues to contact with ultraviolet rays, it will form lipid peroxides, which will disturb the rhythm of skin metabolism and pay special attention.

5, UV

UVA will penetrate and destroy the dermis layer, invading collagen fibers and elastic fibers, causing it to deteriorate, leaving a block in the dermis layer, leaving the skin feeling translucent and yellowish and dull.
