Essence for whitening and moisturizing and preparation method thereof

Abstract

The invention belongs to the technical field of cosmetics, and particularly relates to essence for whitening and moisturizing. The essence is prepared from the following components in parts by mass: askincare composition, di (lauramidoglutamine) lysine sodium, carbomer, cetostearyl alcohol, cetostearyl glucoside, polydimethylsiloxane, a polydimethylsiloxane cross-linked polymer, titanium dioxide,hydrogenated lecithin, phenoxyethanol, benzoic acid, ethylene glycol and deionized water. The skincare composition is prepared from the following components in parts by weight: 20 to 35 parts of cyanotis arachnoidea extract, 5 to 22 parts of chondrus crispus extract, 1 to 5 parts of crithmum maritimum extract and 3 to 12 parts of sea buckthorn fruit extract. The essence disclosed by the inventionachieves the purpose of effectively relieving pigmentation after facial inflammation by repairing skin internal inflammation and fading dermis pigment, and can prevent skin aging and enable the skinto be white and fine.

Description

technical field [0001] The invention belongs to the technical field of cosmetics. More specifically, it relates to an essence for whitening and moisturizing and a preparation method thereof. Background technique [0002] The water content of the skin in the human body is 15-20% of the body weight, and if the water content of the skin decreases, the skin will be dry, dull, low in elasticity, and wrinkled. At present, moisturizers commonly used in cosmetics are mainly divided into occlusive moisturizers, hygroscopic moisturizers, and hydrating moisturizers. The former achieves moisturizing effect by preventing the moisture in the skin from evaporating, and hygroscopic moisturizers mainly absorb moisture from the external environment. Supplement into the stratum corneum to achieve moisturizing effect; while hydrating moisturizers need to combine with water molecules in the environment to form a network structure to replenish moisture for the skin. However, when the human body...

Problems solved by technology

Therefore, in a dry environment, the moisture content of the skin will be significantly reduced, and the skin will become dry. The closed moisturizer cannot effectively prevent the evaporation of skin moisture, and because there is less moisture in the dry environment, it cannot absorb moisture from the external environment or communicate with the outside world. The moisture in the environment is hydrated to achieve the effect of moisturizing, and because most people have the problem of damaged stratum corneum, they cannot effectively prevent the loss of moisture, which is especially obvious in dry environments

Therefore, the current moisturizing cosmetics cannot guarantee effective moisturizing in a dry environment

[0003] Post-inflammatory hyperpigmentation is a rare disease state of hyperpigmentation of the skin, which is mainly related to the invasion of mediators and cytokines of oxidative stress and inflammation. To inhibit the further deposition of melanin, but the course of treatment is longer; secondly, azelaic acid, kojic acid and other inhibitors that inhibit tyrosinase activity are often used to treat post-inflammatory pigmentation, but most clinical application tests show that it can significantly increase The visual difference between the post-inflammatory hyperpigmentation site and other parts has no significant effect on the removal of melanin in the pigmentation site. This is because the action site is different. Tyrosinase inhibitors generally act on the surface of the skin, so they have a greater effect on conventional melanin. Good clearing effect, whitening effect is obvious, but the melanin produced after inflammation is mainly deposited in the dermis, the above-mentioned inhibitors cannot work in a short time, and the skin side effects caused by such inhibitors are relatively common
