sk2 light bulb ingredients list

1. Hydrating and moisturizing ingredients

(1) Butylene glycol and glycerin: Butylene glycol and glycerin are a perfect combination for hydrating and moisturizing. They both have good hygroscopicity. Glycerin replenishes moisture by absorbing moisture from the air, while butylene glycol locks moisture in the stratum corneum. The combination of the two improves the moisturizing effect. However, glycerin will absorb water from the skin in dry air, so pure glycerin skin care products should not be used. (2) Panthenol Inositol: Inositol is a plant extract with the same effect as VB. It has a moisturizing and conditioning effect on the skin. Panthenol can increase the content of hyaluronic acid in the skin and promote the metabolism rate through interaction with VB. Compared with glycerin, it is a non-sticky moisturizing ingredient. The interaction between these two moisturizers can improve the skin's ability to absorb and penetrate.

2. Whitening ingredients

(1) Galactomyces fermentation filtrate: This is a natural yeast extract that is often added to high-end skin care products. It is a small molecule ingredient that can produce VB and amino acids to help improve skin care effects. Its most obvious effect is to condition the skin, improve oil balance and brighten the skin. (2) Niacinamide: Niacinamide is a medicinal ingredient with high safety. Research in recent years has found that it can effectively inhibit the deposition of melanin. In addition to the most traditional whitening effect, niacinamide also has the effect of clearing melanin that has already been deposited. (3) Undecylenoyl phenylalanine: This is a melanocyte-stimulating hormone receptor antagonist. In layman's terms, it can bind to the melanocyte-stimulating hormone receptor but is inactive. It can effectively reduce the production of melanin and play a whitening role. However, due to its poor permeability, the whitening effect is not very obvious.

3. Instant brightening ingredients

(1) Mica: Mica is a mineral ingredient that is not absorbed by the skin and does not cause damage to the skin. It is mainly used to enhance the instant brightening effect of cosmetics. Mica acts like a small mirror, increasing brightness and improving skin texture. (2) Boron nitride: Boron nitride is non-toxic and has a lubricating effect. It can make the texture of cosmetics smooth and easy to apply. Its effect is similar to talcum powder and has a certain concealing ability. At the same time, boron nitride is white in color and can instantly whiten and brighten the skin.
