Our skin tissue can be roughly divided into three layers: epidermis, dermis, and subcutaneous tissue.
1 Epidermis: It is the outermost protective film of the skin, protecting the skin against foreign substances.
2 dermis layer: composed of elastic fiber and collagen, tough and very flexible, mainly to manage the elasticity and aging of the skin.
3 subcutaneous tissue: the innermost layer of the skin, composed of fat cells, plays a role in the body’s thermal insulation.
These three layers of skin are very hydrophobic, which is why you don’t get water to become a big fat after swimming.
This layer of skin is your body’s barrier, protecting you from bacteria, viruses and so on.
The skin barrier not only blocks bacteria and viruses, but also blocks the absorption of skin care products.
Therefore, only a small part of the skin care products applied to the face can be absorbed by the skin!
So how are skin care products absorbed?
Our skin absorbs skin care products mainly through the stratum corneum, hair follicles, sebaceous glands, and sweat glands. The stratum corneum is the most important way for skin to absorb skin care products. Hair follicles, sebaceous glands, and sweat glands, these organs absorb very little skin care products.
In general, skin care products are divided into three categories: water-oil mixed type, water-soluble type, and fat-soluble type.
Water-soluble skin care products generally only stay in the stratum corneum and will not be absorbed down. These skin care products will hydrate and moisturize the skin and increase the water content of the stratum corneum. Once the water content of the stratum corneum is increased, the skin can more easily absorb the nutrients of the skin care products.
Other oily skin care products such as creams, creams, masks, etc. are all water-oil mixed cosmetics. Oil-soluble essential oils, etc., are fat-soluble skin care products. The fat-soluble substances in these two types of skin care products will be absorbed by the skin through your keratin in the gap between the cells.
In other words, the lotion can only act on the stratum corneum, giving the stratum corneum a moisturizing and moisturizing effect. Creams, creams, masks, essences and other skin care products can be absorbed by the skin.
Therefore, when we are in skin care, we usually apply lotion first, so that when the cuticle is enough to drink water, we use skin care products such as essence and cream to supplement the skin with nutrients.
