Hydrating is the classic topic in skincare, dehydrated skin should not be ignored. Today, let’s talk about the dangers of dehydrated skin and some hydrating ingredients in skin care products.
- The skin becomes rough and tense. The water content of the stratum corneum of the skin is generally 20%-30%. When the water content is less than 10%, the normal metabolism of the stratum corneum cannot be carried out.
- The skin develops fine wrinkles. The ability of the epidermis to retain water is reduced, resulting in dry lines.
- Easily stained. The water in the pigment cells of the skin and the surrounding cell fluid are severely dehydrated, making the pigment aggravated.
- The skin can become sensitive easily. Lack of water will make the skin capillaries dilate, the skin’s resistance will decrease, and it will be vulnerable to external stimuli.
Hydrating ingredients
Ceramide
The content of ceramide affects the degree of skin dryness. It is a lipid present in the skin and plays an important role in the formation of the epidermis stratum corneum. When the skin is dry and dehydrated, skin supplementation with ceramides can quickly restore moisturizing and barrier function.
Centella Asiatica Extract
Madecassoside has a good polymerization effect with phospholipid substances in the stratum corneum. In addition, the extract also contains hydrophilic triterpenoid saponin compounds, which can significantly increase the hydration level of the stratum corneum, replenish skin moisture, and synergistically repair skin barrier function.
Amino Acid
The molecular structure of amino acid components can easily penetrate into our skin, repair the vitality of skin cells, promote skin metabolism, and stimulate cell regeneration. At the same time, amino acids are also highly moisturizing, keeping the skin hydrated and elastic.
Glycerin (Glycerol)
Glycerin is a component present in our skin that fills the intercellular substance and absorbs the right amount of water to maintain cell ability. However, it is not recommended to use glycerin in areas that are too dry, because glycerin will not release moisture after absorption, and will cause the skin to lose more moisture.
