Both glycolic acid and niacinamide are effective ingredients for acne, but they work in different ways.
-
Glycolic acid is an alpha hydroxy acid (AHA) that exfoliates the skin, removing dead skin cells and unclogging pores. This helps to prevent breakouts and reduce the appearance of acne scars.
-
Niacinamide is a form of vitamin B3 that reduces inflammation and controls oil production. It also helps to improve the skin barrier, which can help to prevent acne.
The best ingredient for you will depend on your individual skin type and concerns.
-
If you have oily skin and are prone to breakouts, niacinamide may be a better choice.
-
If you have acne scars or hyperpigmentation, glycolic acid may be more effective.
You can also use both glycolic acid and niacinamide together in your skincare routine. However, it is important to start with low concentrations and gradually increase them as your skin becomes accustomed to the ingredients.
