Traditional Chinese medicine composition having sunscreen synergistic and anti-aging functions, and preparation method and application of same

Abstract

The invention relates to a traditional Chinese medicine composition, a preparation method and an application thereof. The traditional Chinese medicine composition is composed of, by weight, 20-30 parts of sunflower, 15-25 parts of chamomile, 15-25 parts of aloe, 5-15 parts of rosemary, 5-10 parts of mint, and 5-15 parts of melissa officinalis. The traditional Chinese medicine composition has reasonable formula and allows synergistic effect, not only can delay the inflammation on skin due to ultraviolet irradiation and has significant sunscreen effect, but also can remove hydroxyl free radicalsand has significant anti-aging function. By applying the composition to cosmetics, a product has stable property, has higher SPF and PFA value than conventional sunscreen products and is better in tenderness.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicines, and relates to a traditional Chinese medicine composition and its preparation method and application, in particular to a traditional Chinese medicine composition with sunscreen synergistic and anti-aging effects, its preparation method and its application. Background technique [0002] Skin aging is an irreversible natural phenomenon of the human body. There are many external and internal factors. Among them, ultraviolet rays are one of the main factors that cause dark aging of the skin and the formation of spots on the skin surface. Only good ultraviolet protection can effectively prevent melanin. Excessive production can keep youthful and moist at all times. The ultraviolet spectrum in sunlight is in the 200-400nm wavelength range, which can be divided into three bands, namely short-wave ultraviolet (UVC) with a wavelength of 200-290nm, medium-wave ultraviolet (UVB) with a wavelengt...

AI Technical Summary

Problems solved by technology

The principle of physical protection is to reflect and scatter ultraviolet rays. Its advantages are light stability, wide protection range, large molecular weight, and not absorbed by the skin. It is relatively safe for sensitive skin. The disadvantage is that the texture is generally thick and heavy, and it is easy to turn white after application. And the protection ability is relatively weak; chemical protection converts light energy into heat energy, fluorescence or phosphorescence by absorbing ultraviolet rays. Its advantages are strong ultraviolet protection ability in a certain wavelength range, light and thin texture, and partially soluble in water. Small molecular weight, can penetrate into the skin, potentially dangerous to the skin, may cause many skin problems such as free radicals, photosensitivity, contact dermatitis, cancer cell proliferation, etc., and is prone to photodegradation, reducing the absorption effect of chemical sunscreens on ultraviolet rays

In addition to the above deficiencies, the current sunscreen products on the market are less concerned about the damage of free radicals to the skin, while anti-aging products often ignore the protection against ultraviolet rays.
