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.
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.
Niacinamide and Salicylic Acid
Salicylic acid works more effectively when layered with niacinamide. Niacinamide is an antioxidant that reduces inflammation and helps with acne. It's always good to use salicylic acid in a cleanser or a face mask and layer it with niacinamide.
Can I use salicylic acid and niacinamide together? Believe it or not, you can! Both of these ingredients deliver some similar and complimentary skin benefits and when used correctly can work really well in your daily skincare routine.
Their most important difference is their mechanism of action. Also, salicylic acid doesn't help hydrate the skin whereas niacinamide does. Sure, salicylic acid may help your moisturiser work better but it can't hydrate the skin on its own. The truth is one isn't better than the other.
By using a salicylic acid enriched wash after cleansing the skin of any remaining makeup, you are helping to rid the skin of any dead skin cell build-up allowing any nourishing products applied afterwards to absorb quicker into the lower layers of the skin and show results quicker.
Use Salicylic Acid in the morning and Retinol at night. Those with more sensitive skin may need to use these products on alternate days, or reduce Salicylic Acid use to once a week or as and when needed.
I started applying salicylic acid after the cleansing and toning steps and before moisturising. It is important that you let your skin absorb the product. While applying salicylic acid, I massage the product into my skin in a circular motion. I also make sure to keep the product away from my eyes and mouth.
Products with salicylic acid can be used either morning or night. When using products with salicylic acid during the day, it is recommended to apply a daily SPF as the last step in your skincare regimen.
Actives That Can be Used With Salicylic Acid
She also suggests combining salicylic acid with hyaluronic acid to enhance skin hydration and counteract any dryness resulting from the exfoliation that salicylic acid provides. Another ingredient to use with salicylic acid is vitamin C.
Apply a small amount of medicine to the affected area and rub in gently. If using the pads, wash the affected skin with a mild cleanser, then pat dry. Wipe the pad gently onto the skin to apply the medication, usually 1 to 3 times a day or as directed by your doctor. Wash hands after use.
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. Marchbein.
