Vitamin C is one of the best extracts that everyone loves because it is a powerful antioxidant that helps fight free radicals that damage the skin, restore damaged cells, stimulate collagen production, protect the skin from pollution, and also help the skin look bright and free of dark spots. But for vitamin C, using it with other skin care products requires special care. Although each product has wonderful properties, using the wrong formula can be a disaster for your skin. Let’s see which extracts should not be used with vitamin C.

Effects of using vitamin C in combination with other substances

Vitamin C + Benzoyl peroxide

Benzoyl peroxide is an over-the-counter medication used to treat moderate to inflammatory acne. This medication not only kills the bacteria that causes acne, but it also helps prevent dry, flaky skin. Using benzoyl peroxide together with vitamin C can actually harm your skin, rather than synergizing each other. When applied to the ยูฟ่าเบท skin, benzoyl peroxide reacts with vitamin C, degrading it and reducing the effectiveness of both.

Vitamin C + Retinol

Retinol is a powerful antioxidant that helps reduce the appearance of wrinkles and stimulates collagen production. It may sound like a good match for vitamin C, but the truth is, using retinol with vitamin C can be disastrous for your skin. When used together, the results are flaky, red, and irritated skin, which is no different from what you would expect from a product . It can also make your skin more sensitive to the sun.

So the best way is to use vitamin C in the morning and retinol at night to get both working most effectively.

Vitamin C + AHAs/BHAs 

Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are both powerful chemical exfoliants that help remove dead skin cells and reveal new, brighter, more radiant skin.

• AHA works by exfoliating the outer layer of skin cells, helping to smooth and brighten the skin, and reduce wrinkles.
• BHA penetrates deep into pores, helping to remove dead skin cells, blackheads and excess oil on the skin.

Both AHA, BHA and Vitamin C are acidic substances, so using AHA/BHA together with Vitamin C may cause skin irritation.

Vitamin C + Niacinamide

Niacinamide, or vitamin B3, is an important nutrient that helps build collagen in the skin, helping to smooth out skin tone, tighten pores, reduce the appearance of wrinkles, and give skin a healthy appearance. It may seem like vitamin B3 would be a good partner for vitamin C, but in reality, using the two together can actually have a negative effect on their effectiveness.

Niacinamide is a weak alkaline. When it comes into contact with the acidic vitamin C, the two react, causing vitamin C to lose its antioxidant properties. In addition, niacinamide reacting with vitamin C can also cause irritation and acne.
