Does niacinamide need to be kept away from light? Niacinamide is not photosensitive and can be used morning and night.

Many fairies have doubts about whether niacinamide needs to be protected from light when using skin care products containing niacinamide. So today let’s take a look at whether niacinamide will “die in the light”?

Does niacinamide need to be protected from light?

There is no need to avoid light when using products containing niacinamide. Just do a good job of sun protection and anti-oxidation during the day. Sun protection is the secret to delaying skin aging and is the most important skin care work. Without sun protection, all your other skin care work will be in vain. Therefore, you must remember to use sunscreen every day. It is not just necessary to use it when using niacinamide products, but you must do a good job of sunscreen care every day for 365 days.

Which skin care ingredients need to be protected from light?

VC

The first type is easily inactivated by light, such as VC, and it is best to use it away from light. If you want to use it to enhance sun protection and anti-oxidation, you can also use it during the day under strict sun protection;

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.

Fruit acid, salicylic acid

The second type is relatively safe in itself, but may aggravate UV damage, such as fruit acid and salicylic acid. It is safer and more effective to use 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".

Vitamin A

It is recommended that you use vitamin A ingredients away from light. Including retinoic acid, retinol and some retinol derivatives. The reasons why they are not recommended for use during the day are: they will decompose quickly when exposed to air and light; they can promote skin cell renewal and metabolism, which may increase some people's sensitivity to light. In general, vitamin A products may have adverse effects on the skin when used during the day, and can only exert their greatest value when used at night.

Phototoxic elements such as furanocoumarins

Furocoumarins are phototoxic ingredients, mainly those plant essential oils containing furanocoumarins. Lemon, sweet orange, grapefruit, bergamot, bitter orange and other Rutaceae plants contain furanocoumarins. So when you use the essential oils of these plants, be especially careful to keep them away from light.

In addition, Umbelliferae plants such as celery, coriander, and angelica that we often eat in daily life also contain furanocoumarins. But there is no need to be afraid, because you have to consume them in very large quantities, such as eating several kilograms, or your skin may come into direct contact with their juice and then be exposed to sunlight, before photosensitivity symptoms may occur.
