Brief Introduction Of Anti-aging Cosmetic Raw Materials

Anti-aging mainly has the following ways and measures: protect skin cells from external environmental stimuli, such as preventing UV (ultraviolet rays) from harming the skin and protecting the skin; removing excess free radicals in the cells; repairing and replenishing skin cells Nutrition.

1. Scavenging free radicals

The harm of excess free radicals:

1. Excess free radicals in the body will react with the unsaturated fatty acids in the body, reduce the flexibility of the membrane, cause abnormal cell membrane function, and make the body in an abnormal state. The skin is dry and wrinkles appear on the skin;

2. Then it reacts further to produce fluorescent substances, which will appear as senile plaques on the skin after aggregation;

3. In addition, free radicals can also cause the cross-linking of collagen in connective tissues and reduce the solubility of collagen. The manifestation in the body is that the skin is not elastic, dull, the bones become brittle, and the eye lens becomes turbid.

Free radical scavenging raw materials: tocopherol (vitamin E), ascorbic acid (vitamin C), coenzyme Q10 (ubiquinone), lipoic acid, carotenoids, glutathione, astaxanthin, resveratrol, proanthocyanidins, grapes Seed extract, etc.

2. UV absorption

Mainly some sunscreens, by absorbing ultraviolet rays, reduce free radicals generated by light.

UVA absorbers are organic compounds that tend to absorb ultraviolet radiation in the wavelength range of 320-400nm. Commonly used are benzophenones, anthranilates and dibenzoylmethane compounds.

UVB absorbers are organic compounds that tend to absorb ultraviolet radiation in the wavelength range of 290-320nm. Commonly used are derivatives of para-aminobenzoate, salicylate, cinnamate, and camphor.

Three, cell repair

When the collagen of the dermis decreases, the elasticity of the skin decreases and wrinkles are produced. Therefore, promoting the growth of collagen can alleviate the aging of the skin.

Repair materials: Retinol (promote epidermal metabolism, hyperplasia of epidermis and connective tissue), retinol (vitamin A), hydrolyzed collagen (can be absorbed by the skin and filled between the skin matrix, so as to make the skin plump) Wait.

Fourth, moisturizing

Skin moisturizing is the prerequisite for all other functional cosmetics to function.

Moisturizing raw materials are divided into three categories: sealing agents (vaseline, lanolin, mineral oil, etc.), hygroscopic agents (glycerin, butylene glycol, sorbitol, etc.) and biomimetic agents (hyaluronic acid, ceramide, etc.).
