Many people think that vitamin C is not safe to use with niacinamide. Some people say that vitamin C and niacinamide are chemicals that cause irritation if used together. Even though vitamin C can be used with niacinamide, you need to pay attention to several things. See the explanation below.
All About Vitamin C and Niacinamide
Niacinamide and ascorbic acid are good skin care ingredients. Vitamin C not only functions as an antioxidant that dissolves in water, but also increases collagen production in the skin which can help reduce some of the adverse effects caused by UV exposure. Niacinamide is an anti-inflammatory agent that is good for treating inflammatory conditions such as acne and is proven to increase natural moisturizers on the skin. Both of these ingredients are very effective for reducing skin hyperpigmentation, it’s no wonder that many products use this ingredient.
Vitamin C and Niacinamide According to Several Researches
Some people are afraid to use vitamin C and niacinamide together because they will collide with each other which make these two ingredients ineffective. Even some studies reveal that vitamin C is a material that is difficult to process, this makes vitamin C must be formulated appropriately.
Many articles claim that niacinamide and vitamin C are indeed difficult to combine. This was revealed by many studies over 40 years ago. Studies show a mismatch between niacinamide and vitamin C because they use a second form of material that is not stabilized, while the two ingredients are usually stabilized when used in modern cosmetic formulas.
Niacinamide is a fairly strong material, light and air do not have the same effect on them as in antioxidants such as vitamin C. Niacinamide is a product that is formulated at near neutral pH. Vitamin C (pure ascorbic acid), on the other hand, is best used in a low pH (acid) environment. However, unwanted by-product nicotinic acid from niacinamide and vitamin C becomes problematic only when niacinamide and vitamin C are combined in a high-temperature environment for a long time.
Vitamin C and Niacinamide Can be Used Together
Using Niacinamide and Vitamin C together is actually safe. These two ingredients used in one product or combined from various products are not a problem. However, if you have sensitive skin and are worried that there will be side effects from these two ingredients, you should consult a doctor or use different times such as vitamin C in the morning and Niacinamide at night.
The benefits of the mixture of these two ingredients are very many. Niacinamide is a skin whitening ingredient that will shrink skin pores, camouflage fine lines and dull skin. Vitamin C is a powerful antioxidant that protects the skin from pollution and brightens the face that can disguise the signs of skin aging.
