Like glycolic acid, salicylic acid has an exfoliating effect on the skin. It can also remove excess sebum (oil) and reduce sebum production, making it an excellent ingredient for unclogging pores. Plus, salicylic acid has mild anti-inflammatory and antimicrobial properties.
Here's the not-so-great thing about salicylic acid: It takes a minute to see it work. “You'll likely see results in four to six weeks,” says Dr. Nazarian, “after which you should continue to use it for long-term effects.” That means you shouldn't expect any miracles overnight—good skin requires patience, y'all.
Short answer? It's a type of chemical exfoliant. More specifically, it's a beta hydroxy acid (BHA) that's derived from willow tree bark. It's particularly effective at treating blackheads and whiteheads because it's oil-soluble and thus able to penetrate the skin at a deeper level.
It is safe to use products with salicylic acid every day, unless it is specified otherwise on the product usage guidelines or by your health care professional. CeraVe's SA Smoothing Cream and SA Smoothing Cleanser are suitable for daily use.
Salicylic acid penetrates into your skin and works to dissolve the dead skin cells clogging your pores. It can take several weeks of use for you to see its full effect.
Salicylic acid is also an exfoliant.
Salicylic acid is considered a keratolytic medication, which means that it's perfect for supreme exfoliation. "Keratolytic medications cause softening and sloughing of the top layer of skin cells," says Rachel Nazarian, M.D., a board-certified dermatologist in New York City.
Can I use a salicylic acid cleanser and exfoliator? No, avoid using a salicylic acid cleanser and exfoliator as this can cause extreme irritation and dryness.
Salicylic acid is the preferred ingredient for treating blackheads and whiteheads because it breaks down the materials that clog pores: excess oil. dead skin cells.
Can I moisturise after salicylic acid? Absolutely, if anything I strongly suggest moisturising after using salicylic acid. Not only will this soothe and calm the skin after applying the potent BHA to your skin.
Can I apply moisturizer after using salicylic acid? Yes. Moisturizers can help hydrate and repair skin, making it a good step to do after using an exfoliating treatment with salicylic acid.
“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.
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.
A salicylic acid cleanser is a good ally for acne-prone skin types, as it'll help keep pores consistently clear, preventing breakouts before they occur. A serum is another good option, while easily overloaded skin will love a water-weight salicylic acid toner or treatment mist.
Salicylic acid decreases postacne hyperpigmentation by its anti-inflammatory effects. Ahn and Kim[18] found salicylic acid to have a whitening effect on the skin as well. Mandelic acid also has a beneficial effect in improving skin pigmentation.
"Salicylic acid is oil soluble, meaning it's able to get inside pores to gently push out dead skin, bacteria, sebum, and any other pore-clogging debris." By removing that debris from your pores, your pores will appear smaller.
Apply a topical salicylic acid to the spot.
If you find the over-the-counter creams to be too harsh and drying, try a toner with salicylic acid. Salicylic acid works to promote the shedding of the epidermis more readily, open clogged pores and neutralize bacteria within.
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.
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.
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.
Glycolic acid is an effective exfoliant, meaning it can remove dead skin cells. It's well suited to reducing hyperpigmentation, fine lines, and uneven skin tone. If you have acne-prone skin, salicylic acid is usually a better option. It can get rid of excess sebum and prevent or treat acne.
Salicylic acid is a beta-hydroxy acid (BHA), a type of acid that is derived from natural sources such as willow tree bark, wintergreen leaves or sweet birch bark. Although it is the best-known BHA, there are several other, less common BHAs that exert a similar effect on the skin: Betaine salicylate.
Salicylic acid can be useful in helping to even the skin tone and reduce discoloration due to its astringent properties [3].
