Can niacinamide be used together with VC? Will niacinamide destroy the VC ingredients?

Niacinamide and VC are both very effective whitening products. Many girls use these two products, and some girls even use them at the same time. So, can niacinamide and VC be used together? You will know after reading this.

Can niacinamide be used together with VC?

Niacinamide can be used together with VC, which also has whitening effects. The whitening effect is even better when the two are used together.

In fact, niacinamide is much more powerful than we think. Although experiments have shown that niacinamide and vitamin C have a chance to synthesize niacinamide ascorbate through electron transfer, many people will be worried. However, don't worry, the synthetic molecular structure is very weak and will fall apart if you are not careful. Moreover, the best synthesis condition for the two is when the pH value is 3.8. However, we should know that in most cases the pH value of our skin care products is only between 5 and 7, which is far from meeting the conditions for the combination of the two.

Does niacinamide destroy the vitamin C component?

Niacinamide and vitamin C can indeed form an acid-base complex that is slightly yellowish in color. However, this complex will not only not make vitamin C inactive, but can protect the activity of vitamin C very well, so that it will not be quickly oxidized and lose its activity.

In addition, this complex is easy to form and also very easy to dissolve. After penetrating into the skin, they will slowly loosen up and play their respective roles. Moreover, as a member of the B vitamins, niacinamide and vitamin C have a very good synergistic effect in the skin, just like vitamin C and vitamin E, a pair of good friends, synergistically improving the skin!

What should not be used with niacinamide?

Niacinamide + alpha alcohol/acid (√)

Effectively reduce the irritation caused by alcohol/acid 1+1>2

Niacinamide + low pH acid, such as salicylic acid (×)

At low pH values, niacinamide will turn into niacin, increasing irritation to the skin and causing intolerance (you can try it at low concentrations)

Nicotinamide + vc (O)

Many cosmetics add these two together, which is feasible, but you have to be careful when stacking them yourself. Low concentrations can be stacked together, but when the concentration is high, the integrity of VC will be destroyed, and niacinamide will also be converted into niacin due to the acidity of high VC, which increases irritation. This is something you need to pay attention to.
