Since chemical exfoliants aid in the dissolving of dead skin cells to reveal the fresh new skin cells underneath, using salicylic acid on skin regularly can help fade dark spots over time. The key is consistency, so don't be discouraged if you don't see immediate changes.
Does salicylic acid remove dark spots? Yes, but don't expect to see immediate changes. "It can help fade dark spots over time, but it should be used in combination with other ingredients like vitamin C, niacinamide and hydroquinone for best results," says Dr. Shokeen.
Salicylic Acid 2% Anhydrous is a gentle formula that is designed to exfoliate the skin, decongest pores, smooth textural irregularities, and reduce redness and uneven skin tone.
Glycolic acid has now become one of the most recommended skincare ingredients for hyperpigmentation, dark spots, and dullness treatment. If you are in search of the best serum for hyperpigmentation, you can choose the one that comes with glycolic acid.
For milder forms of acne scars, such as superficial scars and post-inflammatory hyperpigmentation (PIH), some people may start noticing subtle improvements within a few weeks of regular use. However, to achieve more significant results, it can take around 2 to 3 months of consistent application.
Can I leave salicylic acid overnight? Yes, you can, but only once you have built the skin's tolerance. For those with a skin type that is oily and prone to acne and breakouts, salicylic acid is the best ingredient to use to combat any concerns.
Specifically for at home use, Reszko suggests people use a selection of hydroquinone, retinoids, vitamin C, and kojic acid. “These active ingredients work by inhibiting melanin production and promoting skin cell turnover.” Sun protection is also key in preventing the production or worsening of dark spots.
Skin concerns: Because of their different modes of action, glycolic acid is generally better suited for addressing surface-level skin concerns such as hyperpigmentation, uneven skin texture, and signs of aging. Salicylic acid is better suited for addressing acne, blackheads, and other types of clogged pores.
Kojic acid
Kojic acid has skin-lightening properties that can help reduce the appearance of dark patches associated with melasma. It inhibits the production of melanin, the pigment responsible for skin color10.
It's fine to use Salicylic Acid as part of your daily skincare routine. Doing so will help to keep your skin clarified and refreshed while limiting excess oil production.
Salicylic Acid is considered to be one of the most effective peeling agents. Using Salicylic Acid with Retinol or Benzoyl Peroxide can dry out the skin, causing flakiness and redness.
Lactic acid treats acne, acne scarring, dark spots, hyperpigmentation, photoaging, and other skin blemishes.
For sensitive skin, start with salicylic acid, since it's less likely to cause irritation. If you're already using an oral or topical treatment for acne, benzoyl peroxide might be a more effective option — but start with a lower concentration and gradually move up from there to see what your skin can tolerate.
After about a month, you should notice clearer skin as glycolic acid works to keep skin clean and decongested. Two months in, you should see that dark spots and pigmentation is reduced as the regular glycolic acid application is melting away old, dead skin cells and increasing cell turnover.
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.
Is skin discoloration reversible? The reversibility of skin discoloration depends on the cause. Dermatologists can recommend treatments such as topical creams, laser therapy, or chemical peels based on the specific condition.
Most people (bar those with super-sensitive skin) should be able to use a Salicylic acid cleanser every day. The other exception is face masks, which are designed to be an added extra when your skin needs a little extra TLC – not a daily part of your routine.
Salicylic acid can be drying to the skin, so it's important to moisturize your skin after using it. Look for a moisturizer that is lightweight, non-comedogenic, and free of fragrances and other irritants. Moisturizing after using salicylic acid can help to soothe the skin and prevent dryness and irritation.
