“AHAs and BHAs can certainly be combined. For example, for oily skin, a salicylic-based cleanser can be used followed by a glycolic acid toner. Generally, a glycolic acid is great for dry, dehydrated or combination skin, whereas salicylic acid would be perfect for oily/spot-prone/acne skin.
Salicylic acid can be paired with popular ingredients like hyaluronic acid and niacinamide if you want to decongest your pores and avoid dryness.
GOOD: AHAs (Glycolic Acid) + BHAs (Salicylic Acid)
Dr. Shainhouse says to use a mix of glycolic acid, salicylic acid and benzoyl peroxide to get the job done. “The acids exfoliate the skin, enabling the benzoyl peroxide to penetrate deeper for improved anti-inflammatory and antibacterial effect,” she explains.
Luckily for us, yes, niacinamide is perfectly safe to use with salicylic acid due to the fact it contains humectant properties. This allows the ingredient to absorb moisture from the surrounding atmosphere and other product formulas and locking them into the different layers of 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.
Niacinamide tends to work best in an environment with a neutral pH and because salicylic acid is, well, an acid it does not have a netural pH – it has an acidic one. If you want to use them both one after the other, the best thing to do is apply your salicylic acid, wait 10-30 minutes then apply your niacinamide.
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.
Do you apply salicylic acid before or after moisturiser? Generally speaking, the most potent skin products containing salicylic acid are those such as serums, spot treatments and cleansers, all of which are applied before moisturisers.
Salicylic acid and vitamin C are both effective products on their own but, when combined, they can be even more beneficial.

The best time to apply toner is right after cleansing your skin. You don't need to wash toner off after applying it to your skin. Toner with salicylic acid is one of the best ways to fight acne. Toner can be drying, so start by applying it a few times a week to see how your skin reacts.
You want to make sure that you're not using a product that has too high of a concentration of salicylic acid. Gels should have no more than 5% acid. Lotions that are applied once or twice a day should have 1–2% salicylic acid, and solutions like cleansers or toners should have 0.5–2% salicylic acid.
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.
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.
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.

To fight the good fight against acne, you may also use salicylic acid, a beta hydroxy acid (BHA) that increases skin cell turnover, to keep pores clear. But on its own, each can dry out the skin, so together they should be combined with caution.
Generally, it is not recommended to use a Salicylic Acid cleanser or leave-on exfoliant with Retinol since it can lead to dry skin, leading to other irritation. However, for people with oily acne-prone skin or oily mature skin, the combination can be beneficial.
“You can use a salicylic acid–based cleanser in the morning to unclog pores and avoid acne and a glycolic acid–based cleanser at night to exfoliate your skin and get rid of dead skin cells,” notes Jailman.
