What is the cause of poor skin absorption

The skin is the outermost protective barrier of the organism, preventing water and certain chemicals from entering the organism as well as absorbing substances that are useful or harmful to the organism. What is the cause of poor skin absorption and what can be done if the skin does not absorb skin care products?

What is the cause of poor skin absorption

The main way of skin absorption is through the cell membrane of the stratum corneum, and also through the hair follicles, sebaceous glands and sweat ducts. Factors affecting skin absorption are mainly divided into two categories: internal and external factors, the following are the main reasons why the skin is not absorbed well.

The stratum corneum is too thick

The skin is mainly composed of epidermal cells, dermal cells and subcutaneous tissue, the stratum corneum cells are the main component of the epidermal cells, the stratum corneum is a layer of aging tough cells, the skin oil a certain barrier role, but too thick stratum corneum is easy to affect the skin absorption of nutrients, and the thinner the stratum corneum, the easier it is for external substances to penetrate and be absorbed.

Skin water content is low

The amount of skin sweat is low, the skin is dry, and the oil secretion is insufficient, which can easily cause skin blockage, thus leading to poor absorption ability of the skin; and the more water content of the skin, the stronger the absorption ability.

Pore shrinkage or blockage

Skin pores are the common opening of hair follicles and sebaceous glands, which are the channels for skin to excrete sebum metabolites. If the pores are in a contracted state, or if they are blocked, it will greatly affect the absorption effect of the skin, while when the pores are expanded, the absorption ability is enhanced and the excretion ability is also enhanced, so slightly warm water should be used to clean the face to ensure that the pores are unclogged.

Low local skin temperature

The principle of thermal expansion and contraction also applies to the skin, low skin temperature leads to slow blood circulation of skin end cells, thus the absorption capacity of the skin is correspondingly weaker, while the local skin temperature increases, the absorption capacity of the skin is enhanced, so the use of skin care products in the late winter and early spring cold season should rub hot hands and massage the facial skin, which helps the absorption of the skin.

Skin breakage

When the broken skin is damaged, the barrier role of the skin is destroyed and the absorption capacity is enhanced while harmful substances are more likely to invade the body. The above internal causes of poor skin absorption, the following will introduce the external factors that affect skin absorption.

Type of substance

Skin secretion of oil is rich, fat-soluble substances are more easily absorbed by the skin, while water-soluble substances are more difficult to be absorbed by the skin.

Concentration of substances and contact time with skin

The higher the concentration of the skin care products used, the better the degree of absorption of the skin, and the longer the contact time with the skin, the higher the absorption rate. If you use a mask, the winter temperature is low, the absorption effect of the skin is not good, you can extend the mask time in moderation.

Substance form

Gaseous substances such as oxygen and carbon dioxide can be absorbed by the skin in small amounts, powders and water substances are difficult to be absorbed, ingredients in creams can be absorbed in small amounts, and ingredients within ointments and hard creams (creams) are easily absorbed by the skin.

The best time for skin absorption

The formation of skin tissue components, skin absorption of external nutrients, are closely related to the skin's metabolism, and the skin's metabolic function is most active at 10:00 p.m. to 2:00 a.m., so the use of night cream at night, and maintain a good sleep during this time, the most conducive to skin absorption of nutrients. So the best time for skin absorption is at 10pm~2am.
