Can glycolic acid be mixed with salicylic acid? You can certainly use glycolic acid and salicylic acid together, but we would suggest avoiding mixing them together. This is because combining such potent ingredients will cause a severe reaction to the skin, as well as potentially damaging the skin barrier.
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.
Having two different cleansers for morning and night sounds unnecessary, but Jaliman says it's good to mix it up. “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.
One ingredient that can be layered with glycolic acid with no worry of irritation is hyaluronic acid as this humectant can instantly hydrate the skin and aid replenishment, this is an ideal teammate for glycolic acid as it avoids any chances of the skin feeling tight, dry or irritated.
But in general, salicylic acid is the better choice. Unlike glycolic acid, salicylic acid decreases sebum in the skin. This is important because sebum can clog pores, which increases your risk of an acne breakout. Excess sebum also promotes the growth of bacteria that can cause acne.
“A cleanser with a light salicylic acid coupled with a 10 percent glycolic toner works well to unclog pores, decrease acne breakouts, and mattify the skin,” she notes. Pigmented and aging skin also fare especially well when combining chemical exfoliators.
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.
Don't use with: Although salicylic acid can be combined with other exfoliating ingredients, Mudgil says that in order to avoid irritation, it's best to stick to only one exfoliant at a time.
A salicylic acid cleanser can be combined with a serum for oily skin and acne-prone skin, but people with dry skin should not go overboard. Salicylic acid lotion and serum should not be used together for any skin type as too much of anything can be destructive.
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.
Even though niacinamide and glycolic acid are both natural and have similar benefits, it is not advisable to use them together because of their pH levels. While niacinamide has a much higher pH level than glycolic acid, it won't get completely absorbed into the skin.
Niacinamide and salicylic acid are both great ingredients for treating acne and have a variety of other benefits as well. Salicylic acid is the better option for treating acne, while niacinamide is great for fading scarring and hyperpigmentation.
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 glycolic acid are both common ingredients in exfoliating products. Glycolic acid helps to break down the top layer of dead skin cells to encourage a smoother complexion. Niacinamide increases the skin's elasticity to help improve the appearance of fine wrinkles and lines.
If you want, you can also use a toner, such as Bye Bye Pores Leave-On Solution Pore-Refining Toner, which has a mattifying effect. In the evenings, we recommend using your glycolic acid product followed by a moisturizer.
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.
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.
Using both together will however can become too much for the skin and lead to irritation, rashes, redness, flakiness and all-round discomfort. Much like vitamin C and niacinamide, if you are wanting to use both separate the products completely and apply salicylic acid in the morning and retinol for the evening.
"If salicylic acid is an ingredient in your cleanser, it is fine to use it every day." However, if you are using an exfoliant that salicylic acid in the formula, Dr. Hu advises only using the product three times per week, to avoid over-exfoliating the skin and drying it out.
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.
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.
You can actually layer your glycolic acid and niacinamide together, at the same time of day—just 30 minutes apart. When layering products, start with the one that has the lowest pH first. This will be your glycolic acid, which you'll apply straight after cleansing.
The variance of pH between glycolic acid and niacinamide products can make the products less effective when used together. If you apply niacinamide directly after glycolic acid, it may potentially raise your skin's pH. Unfortunately, it has been shown that AHAs (i.e., glycolic acid) don't absorb as well at higher pHs.
Don't use it daily otherwise you risk damaging your skin barrier by over-exfoliating. Do not apply it on damp skin! Glycolic Acid increases sensitivity towards the sun so a good sunscreen is mandatory.
Glycolic acid should always be applied in the evening, as it makes your skin sensitive to sunlight. Applying it at night gives ample time for it to do its magic without a higher risk or damaging your skin in the sun.
