Why exfoliate? How to judge whether the face needs exfoliation?

We should often hear the word 'exfoliation' in the videos of beauty bloggers, especially for people with oily acne skin, exfoliation is a very important thing. So what is cutin? Why exfoliate? How to judge whether the face should be exfoliated? Let's take a look at this article.

What is cutin

Cuticle is the main component of plant cuticle. It is not a single substance, but a polymer of higher fatty acids (hydroxyc18 fatty acids) with high unsaturation. The composition of cutin can vary greatly depending on the type of plant. Cuticle is the skeleton material of stratum corneum, which generally exists in layers on the surface of stems and leaves. The stratum corneum is the outermost layer of our skin, which is used to protect the skin from light damage of various substances. Generally, the stratum corneum is updated every 14 days. After time, the stratum corneum will fall off from the face, and the new stratum corneum will come to the face to achieve circulation outside.

Why exfoliate

Exfoliation, popularly speaking, is to remove dead skin. The metabolic cycle of human stratum corneum is 28 days, that is, after 28 days, the cells of stratum corneum die and fall off, that is, dead skin is formed. If it does not fall off completely and leave our skin in the normal metabolic period, our stratum corneum will accumulate slowly over time. As the first barrier of the skin, its state directly affects the beauty of the skin.

1. The accumulated cuticle darkens the skin

2. The broken cuticle will form wrinkles

3. Melanin can not be excreted smoothly, and is blocked in the stratum corneum to form color spots

4. The stratum corneum is too thick for nutrients to enter the cells

5. Bacteria will multiply on the stratum corneum, infect hair follicles, grow acne, breed mites and enlarge pores

6. The cuticle is cleaned from time to time. It's useless to apply more skin care products

How to judge whether the face should be exfoliated

1: Look at the absorption of skin care products in the later stage

If the skin care products used want to enter the skin, they first need to pass through the outermost stratum corneum, so the appropriate thickness of stratum corneum will not hinder the skin's absorption of the products. When there is cutin on your face, you will find that you can't absorb it after replacing many products. This is because the aging cutin hinders the absorption of skin care products. Therefore, it is also a way to judge whether there is cutin on the face through the degree and speed of skin absorption of skin care products in the later stage.

2: Frequency of acne and acne

Generally, normal skin will not easily have acne and acne, but when horniness appears on the face, it will make the water and oil in the skin unbalanced, and then there will be too much oil in the skin accumulated in the pores. After the influence of external factors and inadequate cleaning, local acne or acne will appear on the face. When you see the outbreak of acne or acne on a healthy face, it generally proves that there is horniness on the face, so parents can also judge according to the frequency of acne and acne outbreak on the face. 3: Skin peeling

Healthy skin is delicate and smooth, but peeling will make the whole face look bad and unhealthy. But when many people see facial peeling, they feel that the skin is short of water. In fact, in addition to this reason, it is because there is cutin on the face. In this way, the skin can't absorb water and can't supplement it, so the most fundamental reason for peeling on the face is the existence of cutin.

4: Coarse pores, dull

When there is cutin on the face, the overall chromaticity of the skin will be reduced, and the permeability of the skin will be continuously reduced, so the whole face will look dull and dull. With the dull skin, the oil secretion in the skin will be too strong, so the cutin will continue to increase and expand the pores, which will also let everyone see the problem of dull skin and large pores.

5: Greasy face

General skin is also prone to greasy problems, but it is usually caused by facial makeup. But what is the reason why the skin is greasy when it is plain? This is the reason why there is cutin on the face. Once the sebaceous glands of horny skin are strong, the chance of oil will gradually increase. Therefore, it is easy for oily skin to have cutin. After properly cleaning the thick skin, you will find that it is not so easy to oil and much refreshing.
