But overall, stick to using water-based products and serums together. AHAs and BHAs, such as glycolic, salicylic, and lactic acids should never be used with Vitamin C. Vitamin C is an acid, too, and is unstable, so the pH balance will be thrown off by layering these ingredients together and might as well be useless.
Niacinamide & Salicylic Acid
Niacinamide, a water-soluble form of vitamin B3, and salicylic acid, a beta-hydroxy acid, work particularly well when combined together. Both have anti-aging and anti-acne effects and offer some level of UV protection.
Salicylic acid and vitamin C are both effective products on their own but, when combined, they can be even more beneficial. Whether you're looking to brighten your skin, reduce the likelihood of blemishes or just help slow down the skin's natural aging process, these ingredients may be just what you're looking for.
Can niacinamide and salicylic acid be used together? The simple answer is yes. They complement each other well. Being oil soluble, salicylic acid can penetrate deeper into the skin layers, but it can also dehydrate and irritate skin.
Hyaluronic acid is a skin hydrator, not an exfoliant like salicylic acid. You can definitely use both. In fact, applying hyaluronic acid with your salicylic acid is a very good idea. Salicylic acid can be a little drying to the skin because it's job is to absord excess oil.
Can I use salicylic acid, niacinamide, and hyaluronic acid together? You can indeed! The main benefit of using niacinamide and hyaluronic acid together is their ability to provide hydration and protection for the skin.
It is considered the best idea to apply niacinamide before salicylic acid. This is because the humectant traits of niacinamide ensure the natural skin barrier contains the correct levels of water. When the skin barrier is moisturised and healthy it can keep itself protected from exposure to free radical damage.
Salicylic acid is ideally applied to dry skin while hyaluronic acid is ideally applied to damp skin and followed with a heavier moisturizer/occlusive to lock in moisture. Damp skin is more permeable which means that skincare ingredients find it easier to penetrate your skin's barrier.
As for using salicylic acid with hyaluronic acid and niacinamide the best way of applying the all effectively is starting with a exfoliating toner containing salicylic acid, followed with hyaluronic acid to hydrate and prevent skin irritation, then finally niacinamide to regulate the production of sebum of the skin.
These two definitely address a certain skin type: the Niacinamide + Zinc is your best friend if you suffer from oily skin, and combined with the the Salicylic Acid it's perfect to treat blemish- and acne-prone skin.
Don't Mix: Niacinamide and vitamin C. Although they're both antioxidants, vitamin C is one ingredient that's not compatible with niacinamide. "Both are very common antioxidants used in a variety of skincare products, but they should not be used one right after the other," says Dr.
