Background technique

The skin is an important barrier for the human body to defend against external damage. However, changes and stimuli in the external climate and environment will lead to abnormal secretion of sebaceous glands and sweat glands in the skin. People's skin will gradually age, sebum secretion will decrease, and the ability of the skin to retain water will decrease, thus making the skin dry and the cuticle of the skin epidermis increased. Thick, resulting in skin keratinization, chapped, rough skin surface and other problems.

In recent years, with the improvement of living standards, people pay more and more attention to skin care. Essence water is an indispensable product for daily beauty and skin care. It can fully replenish the moisture in the stratum corneum of the skin, and can be used to clean the skin and keep the skin healthy. At the same time, essence water also has the effect of adjusting the acid-base value (ie pH value) of the skin.

However, the matrix raw materials of common essence water mostly come from the hydroxyls and alcohols of mineral petroleum, and the matching raw materials are chemical product colorants and fragrances. These raw materials contain ingredients harmful to human skin, and long-term use will be damaged by skin. Different degrees of absorption and penetration into the human body will have adverse effects on human facial skin and mucous membranes. The quality of essence water is mainly determined by the amount of natural ingredients, but the proportion of natural plant ingredients in cosmetics in the Chinese market is relatively small, and the long-term moisturizing ability is weak and the function is relatively single.
