It can take 6-8 weeks of consistent topical use of salicylic acid before you begin to see improvements. Remember - consistency is key for optimal results. Results will not happen overnight.
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 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. Check with your dermatologist if you aren't seeing results after 6 weeks. Your skin is affected by more than what you put on it.
Salicylic acid is also used in higher concentrations as a peeling agent for treating acne, acne scars, melasma, sun damage, and age spots in dermatology clinics. It's so effective that it's used in wart and corn removal solutions, although it's still safe to use in pigmentation-prone dark skin.
How long does it take for hyperpigmentation to fade? Once what's causing the dark spots or patches is found and stopped, fading can take time. A spot that is a few shades darker than your natural skin color will usually fade within 6 to 12 months. If the color lies deep in your skin, however, fading can take years.
Start with topical OTC whitening creams. “Treatments containing ingredients like vitamin C, licorice root, and kojic acid help reduce hyperpigmentation by inhibiting tyrosinase, an enzyme responsible for the formation of skin-darkening melanin," says Ni'Kita Wilson, a cosmetic chemist.
In this case, turning to dermatological procedures will work as the fastest way to get rid of hyperpigmentation. Chemical peels, laser therapy, microdermabrasion, or dermabrasion are all options that work similarly to rid skin of hyperpigmentation.
When using salicylic acid or other acne treatments, it may take 6-8 weeks to start noticing results. Anyone who does not see an improvement in their acne after this time may wish to contact a doctor or dermatologist for advice on alternative treatment options.
Since these spots are caused by melanin production, the affected skin will shed like all skin cells. On its own, PIH will generally resolve within two years. With intervention, patients no longer have to wait. An effective skincare routine and working with a dermatologist can expedite this process and improve results.
Vitamin C is also a potent antioxidant, which means it protects skin cells from further damage either from the sun or outside pollutants. A small 2004 study found that using 5% ascorbic acid cream — a form of vitamin C — for 16 weeks reduced hyperpigmentation for 62.5% of participants.
You get the maximum benefit when you adjust your skin to start using it twice a day. But, if you are sensitive to salicylic acid and using it up regularly left your skin dry, red, and peeling, then use it as a toner and leave it up for up to 30 seconds and then rinse off.
"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.
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.
This increases the concentration of melanin in the epidermis, creating a temporary darkening of the spots. So, the darkening is what you want to see. It means the pigment is coming up and is ready to be shed away. You might be tempted at this point to over-exfoliate in an attempt to speed up the process even more.
Some cases of hyperpigmentation may never go away completely. If hyperpigmentation is caused by injury, then as the skin heals the discoloration will lessen as melanin is absorbed into the tissue surrounding the injury.
Dark spots appear when the skin cells produce too much melanin. Hyperpigmentation acne may fade over time, but if the original spots were deep, it may be permanent. Although some topical and surgical therapies can speed up the fading process, it can take several months to years.
Hyperpigmentation within the dermis has a blue-gray appearance and may either be permanent or resolve over a protracted period of time if left untreated.
No, salicylic acid is not a skin lightening (as in whitening) agent and therefore, it cannot lighten your skin. However, since salicylic acid has the ability to exfoliate your skin's surface and remove dead skin cells, it can help give your skin a brighter more even complexion.
It is usually triggered by active ingredients that are used to treat the acne. It gets worse before it gets better. Some of these ingredients are retinoids, vitamin C, AHAs and BHAs (glycolic, malic, lactic, and salicylic acid).
Products that may cause purging
Retinoids such as Tretinoin, acids such as salicylic, and benzoyl peroxide are just a few of the products that cause purging. These products contain active ingredients that increase the skin cell turnover rate, therefore causing your skin to purge.

Studies have shown that it helps to decrease pigmentation by preventing the transfer of melanin from the pigment cells to the skin cells.
Acne can sometimes leave dark spots, pockmarks, or scarring on the skin. These are also types of blemishes.
As a pimple heals, your body sometimes produces cells with too much melanin in them to replace the damaged skin. This results in post-inflammatory hyperpigmentation, which we sometimes just call a dark spot.
