Everyone knows that niacinamide has a whitening effect. After using niacinamide for a period of time, the skin becomes visibly whiter. It is an indispensable skin care product for many whitening enthusiasts. Many body lotions containing niacinamide are whitening magic tools. So, how do you use niacinamide body lotion? Can I see the light? Why? Let’s introduce it in detail below!

Why can't niacinamide body lotion be exposed to light?

Many girls have doubts about whether niacinamide products can be exposed to sunlight when using them. In fact, niacinamide can be exposed to light. After using it during the day, you only need to do a good job of sun protection and anti-oxidation, because niacinamide skin care products can delay skin aging, and the effect is better when combined with sun protection. If used normally at night, there will be no adverse reactions.

Which skin care ingredients need to be protected from light?

Kojic acid: We recommend that you only use skin care products containing kojic acid at night. Because kojic acid is very unstable and easily decomposed by light. Many products under the Japanese Kose Group contain kojic acid, so please pay more attention when purchasing.

VC: Some are easily inactivated by light, such as VC, so they should be used away from light. If you want to use it to enhance sun protection and anti-oxidation, you can also use it during the day while strictly wearing sun protection.

Fruit acid and salicylic acid: The second type is relatively safe, but may aggravate UV damage. Fruit acid and salicylic acid are better and more effective when used at night. Because both fruit acid and salicylic acid have certain exfoliating functions, they will cause temporary damage to the skin's barrier function for a period of time, reducing the skin's ability to defend against the sun. In this case, everyone must strengthen sun protection, or simply not use it during the day. If you have had an acid peel or used a product with a relatively high concentration of acid, it is certain! want! Implement the principle of "avoiding light".
