There are several active ingredients that can be paired together and are beneficial for your skin. However, glycolic acid and niacinamide cannot be used together at the same time. This is because mixing these two ingredients can make these acids less effective.
It is said that your skin needs some time between each ingredient that you apply to let it completely absorbed into the skin to make it work efficiently. We can safely say that niacinamide and glycolic acid can work if you choose to use these together but after a gap of at least 30 minutes.
What NOT to mix with Glycolic Acid. Retinol, other AHAs/BHAs, Vitamin C: Using these ingredients alongside Glycolic Acid in the same routine could irritate the skin.
Niacinamide generally works well with most products, but it's best not to combine it with vitamin C (ascorbic acid) in the same routine as it can cause irritation. Additionally, avoid using it with strong exfoliants or retinoids in high concentrations to prevent skin sensitivity. For more, check out my Quora Profile.
Glycolic acid works decently with ceramides niacinmide and of course hyaluronic acid for starters you can gradually add other steps to your routine.
Glycolic acid and niacinamide.
Indeed, niacinamide used with AHA's like glycolic acid and lactic acid has no effect and can even cause redness. Since niacinamide has a pH of about 5-7, it can actually increase the lower pH of glycolic acid, which is about 3-4, and negate its properties.
Apply vitamin C in the morning and glycolic acid at night. Glycolic acid and hyaluronic acid: Since hyaluronic acid loads up skin with moisture, it makes for an excellent pairing with glycolic acid. Look for a product that combines both for easiest application, though you can also layer serums.
Niacinamide and vitamin C
This combination sparks a lot of debate among skincare experts. Some say that since both niacinamide and vitamin C contain antioxidants, they cancel each other out and might even lead to irritation.
Niacinamide works well with other skincare ingredients, including retinol and hyaluronic acid. However, some ingredients, like vitamin C, may interact negatively with niacinamide. Therefore, it's recommended to use products containing these ingredients at different times of the day or on alternate days.
Niacinamide + salicylic acid is what you need in your skincare routine. Salicylic acid is best known for its deep-cleansing properties and deep-penetrating action to unclog pores and slough off dead and dry skin. The antibacterial and anti-inflammatory properties of salicylic acid help clear away pustules and papules.
Hydrate and moisturise: Use hydrating products like serums or moisturisers after using glycolic acid. These aid in rehydrating and nourishing the skin. Look for products that contain hydrating ingredients like hyaluronic acid, ceramides, or natural oils to help maintain a healthy skin barrier.
Retinoids and Glycolic Acid
Retinoids (including retinol) are fantastic for boosting cell turnover and fighting aging. However, pairing them with glycolic acid is like inviting two energetic party crashers into a small room—they can overwhelm your skin.
Niacinamide helps strengthen the skin's lipid barrier, which is crucial for maintaining moisture and protecting against environmental aggressors. By supporting the skin's natural content of ceramides and fatty acids, niacinamide helps to prevent transepidermal water loss, keeping the skin hydrated and resilient.
Mistake 2: Pairing Niacinamide With Incompatible Ingredients
While Niacinamide pairs well with most active ingredients, layering it with an unstable form of Vitamin C or acids like AHAs, BHAs may lead to flare-ups – especially for people with sensitive skin.
Acne-Prone Skin: Glycolic acid exfoliates and prevents clogged pores, while niacinamide calms inflammation and regulates oil. Oily Skin: Niacinamide controls oil production, and glycolic acid smooths rough texture. Combination Skin: Use glycolic acid on areas with roughness and niacinamide for hydration and redness.
If you've ever questioned, “Can I use niacinamide with glycolic acid in my skincare regimen,” don't worry—they most definitely can. Both of these can be used in a single skincare routine. You have to choose the right products from the top brands and follow a healthy skin routine.
DON'T MIX: AHA/BHA and niacinamide
Niacinamide is used to treat hyperpigmentation and reduce fine lines and wrinkles, while alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are chemical exfoliants. To understand why niacinamide shouldn't be mixed with AHAs and BHAs, you need to consider pH.
You might be experiencing breakouts if your skin is too sensitive to niacinamide or if you are using it in combination with other irritating products. These breakouts could be new pimples, redness, and inflammation in areas where you do not normally get acne.
You can (and should) consider layering niacinamide and retinol in the same routine, especially if you have sensitive skin. Retinol is a well-known ingredient that helps reduce the appearance of fine lines, wrinkles and other signs of aging.
Overloading on niacinamide can also lead to breakouts. More isn't always merrier, especially if you've got sensitive or acne-prone skin.
Niacin deficiency is more likely to be caused by problems that affect the absorption of niacin or tryptophan. The most common cause is alcoholism. Other possible causes include disorders of the digestive system and prolonged treatment with the tuberculosis drug isoniazid (Laniazid, Nydrazid).
What NOT to mix with Glycolic Acid. Retinol, other AHAs/BHAs, Vitamin C: Using these ingredients alongside Glycolic Acid in the same routine could irritate the skin. However, alternating them between your morning and evening skincare routine means that you can enjoy the benefits without the risk of damaging your skin.
It is not unusual to find a combination of niacinamide and retinol in a single skincare product, but you can use niacinamide and retinol as separate steps in a consistent routine. If you're using separate products, it is recommended that you apply retinol first then move forward with niacinamide application.
