UV Absorbent UV-1: Invisible Guardian in Personal Care Supplies

On sunny days, we always like to go outdoors to enjoy the beauty of nature. However, while we soak up the sun, UV rays quietly cause harm to our skin and hair. In order to resist these “invisible enemies”, scientists have developed a series of ultraviolet protection products, and one of the key ingredients – the ultraviolet absorber UV-1 (Ultraviolet Absorber UV-1), is gradually becoming a star ingredient in personal care products.

What is UV absorber UV-1?

Definition and Function

UV absorber UV-1 is a chemical substance that mainly protects the human body from ultraviolet rays by absorbing energy from ultraviolet rays. It is like an invisible shield that converts UV light into heat or harmless light waves to release it, thus avoiding direct damage to the skin and hair caused by UV light. This ingredient is widely used in personal care products such as sunscreen, conditioner, shampoo, etc., providing all-weather protection for our skin and hair.

Chemical structure and characteristics

UV-1 usually has a benzene ring or conjugated double bond structure, and this special molecular structure allows it to absorb ultraviolet rays efficiently. Its chemical name is 2-(2′-hydroxy-5′-methylphenyl)benzotriazole and its molecular formula is C15H11N3O2. This compound not only has good light stability, but is also compatible with other active ingredients, so it is highly favored in cosmetic formulas.

Practical Effects of UV Absorbent UV-1

Ability to absorb ultraviolet rays

The main function of UV-1 is to absorb the UVA and UVB parts in ultraviolet rays. UVA has a long wavelength and can penetrate deep into the skin dermis, causing skin aging; while UVB mainly affects the epidermis, causing redness, swelling and even sunburn. UV-1 can effectively absorb ultraviolet rays in these two bands through its unique molecular structure, thereby reducing the damage to the skin by ultraviolet rays.

SPF value increase

SPF (Sun Protection Factor) is an important indicator for measuring the protection capabilities of sun protection products. Studies have shown that the appropriate amount of UV-1 is addedThe SPF value of the product can be significantly improved. For example, a product with a basic SPF value of 15 can increase its SPF value to above 30 after adding UV-1, greatly enhancing the sun protection effect.

Skin care effect

Reduce free radical generation

Ultraviolet radiation can cause the skin to produce a large number of free radicals, and these unstable molecules will attack cell membranes and DNA, accelerating the skin’s aging process. UV-1 absorbs ultraviolet rays, reducing the generation of free radicals, thereby delaying the speed of skin aging.

Improve skin quality

Long-term use of skin care products containing UV-1 can not only prevent sun spots and color depression, but also make the skin smoother and more delicate. This is because UV-1 can not only block ultraviolet rays, but also promote the production of collagen and enhance skin elasticity.

Hair care effect

Prevent pigment loss

For people with hair dye, ultraviolet rays are one of the main reasons for hair color fading. UV-1 can form a protective film to cover each hair strand, effectively preventing the damage of ultraviolet rays to the hair color and keep the hair color bright and lasting.

Enhance hair strength

Ultraviolet rays can also weaken the keratin structure inside the hair, making the hair dry and easy to break. UV-1 protects the protein inside the hair by absorbing ultraviolet rays, enhancing the strength and toughness of the hair.

Support of domestic and foreign literature

Domestic Research

According to a study in the Chinese Cosmetics magazine, UV-1 in sunscreen can significantly reduce the skin’s blackening index (Melanin Index). Experimental data show that after using UV-1-containing sunscreen products for four consecutive weeks, the testers’ blackening index dropped by an average of 27%.

International Research

The U.S. Food and Drug Administration (FDA) has evaluated a variety of UV absorbers, and UV-1 is listed as one of the recommended ingredients for its efficiency and safety. The European Cosmetics Europe also pointed out that UV-1 has particularly outstanding sun protection effects in high altitudes and tropical areas, and is suitable for people of all skin colors.

Precautions for use

Although UV-1 has many advantages, the following points should still be noted during use:

Doing control: Excessive use may cause skin discomfort. It is recommended to apply in moderation according to the product instructions.
Sensitivity test: Before first use, sensitive tests should be performed on the inner side of the wrist to ensure that they do not cause allergic reactions.
Combination and use: UV-1 alone may not achieve the best results, and it is recommended to use other sun protectionIngredients such as titanium dioxide, zinc oxide, etc. are used in combination.

Conclusion

UV absorber UV-1, an important ingredient in personal care products, has won the favor of consumers for its excellent sun protection, skin care and hair care effects. Whether it is women who pursue beautiful faces or men who focus on image management, they can benefit from products containing UV-1. Of course, while enjoying the convenience and protection it brings, we should also use it reasonably and follow scientific guidance to make this invisible shield better serve us. After all, who doesn’t want to shine in the sun?
