5 big white must read common sense together to see

There are many kinds of whitening products on the market. Each product has different whitening effects. For example, some are designed for even skin tone, and some are specially designed for freckles. Before buying, you should understand the ingredients and characteristics of the product, and prescribe the right medicine.

Whitening can only restore the original skin tone

To be deeper, the black and white of the skin is not the standard for judging perfect skin. Perfect skin depends on the uniformity and luster of the skin. If your skin is naturally dark, the purpose of using a whitening product is to remove dull skin and restore even and transparent skin tone, instead of changing the skin tone from natural black to white. The skin will not be whiter than the original skin color due to the whitening product. It is a waste of money to misrepresent the whitening product advertisement.

Sun protection does not leave

Most of the melanin is caused by ultraviolet rays in the sun. If you don't develop the habit of sunscreen, even if you paint a lot of whitening products, it will not help. At least eight days of exposure to sunlight per day, at least apply sunscreen with spf24pa++ or above. But do not greedy the sunscreen too high, the higher the spf degree, the easier it is to block the pores, so the high-degree sunscreen such as spf50pa+++ is only suitable for exposure and long-term outdoor use. Also, don't forget that the eye is thinner than the facial skin, and sun protection is more important.

Moisturize and then whiten

If it is sensitive or dry skin, moisturize the skin before using whitening products, which can improve the moisture of the skin's stratum corneum, healthy skin cell tissue, and reduce the sensitive symptoms produced when using whitening products. Before using whitening products, apply a moisturizing essence to make a base.

Mask should not be applied overnight

Generally whitening mask, unless otherwise specified, usually only 15 minutes is enough. Do not think that the longer the mask is applied, the more effective it will be. Applying mask for too long, facial cells are prone to lack of oxygen, affecting the normal breathing of the skin, the nutrients in the mask can not effectively penetrate into the skin, reducing the effectiveness of the mask.
