Skin purging occurs because of some ingredients that accelerate your body's natural process of getting rid of dead skin cells. Products that contain certain components—including lactic acid, salicylic acid, glycolic acid, and retinoids—are likely the culprits of your acne breakout.
Salicylic acid penetrates 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 .
Salicylic acid also improves the shape of the pore lining, and once the pore is normalized, the backed-up, smaller clog can more easily come to the surface, appearing as new clogged pores (blackheads or white bumps).
If your skin isn't responding to salicylic acid, you can use a topical application of sulfur in conjunction with the acid. Sulphur removes excess oil and removes congestion by increasing skin cell turnover.
Salicylic acid is the preferred ingredient for treating blackheads and whiteheads because it breaks down the materials that clog pores: excess oil.
Signs that treatment is effective
Wart medications, such as salicylic acid, gradually peel away layers of a wart until it reaches the same level as the skin. People may notice the wart becoming flatter over time.
“Gently press on each side of the blackhead until it begins to release,” she says. “Apply slow and even pressure, and once you are able, lightly pinch the tweezers and pull the blacked out material from the skin to extract it. If the blackhead does not release easily, do not continue to attempt the extraction.”
The simple answer is, no. Your skin doesn't build up an immunity to skincare products over time. They don't just one day decide they aren't going to work anymore. This is because there is no direct mechanism for your skin to become immune to the effects of products.
"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 has 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.
If a blackhead is close to the surface of your skin, it's more likely to go away on its own. However, some blackheads can be deeply embedded in your skin. Deep, embedded blackheads are less likely to go away on their own. If you have embedded blackheads, a dermatologist or medical aesthetician can remove them.
Certain products trigger the process of purging. When changing up your regular skincare routine with new products, it is important to note which products are more likely to cause skin purging. Retinoids such as Tretinoin, acids such as salicylic, and benzoyl peroxide are just a few of the products that cause purging.
Products that contain certain components—including lactic acid, salicylic acid, glycolic acid, and retinoids—are likely the culprits of your acne breakout.
The most common cause is oil gland over-production, which can happen during hormonal shifts, such as puberty, menstruation, and pregnancy. Blackheads can also form when hair follicles are irritated or when dead skin cells do not shed regularly.
Salicylic acid starts working by 2-3 weeks, and takes around 2-3 months to show full effect. This potent antioxidant reduces pigmentation and builds up skin collagen. You will start noticing a brighter complexion in 4-6 weeks but actual improvements, in terms of dark spots reduction, will take around 3-4 months.
The general rule of thumb is three times per week for oily or combination skin, and just once weekly for sensitive skin, Dr. Marchbein says.
Applying salicylic acid on areas of your face that have blackheads will help to remove them. Salicylic acid is the only acid that is oil-soluble, so it really works to break down and dissolve the oil in your clogged pores.
Why it might not be working: There are multiple types and causes of acne — and if your acne is severe, salicylic acid might not be strong enough for you. “Cystic acne will need something stronger than salicylic acid,” says Dr. Debra Jaliman, a dermatologist based in New York City.
Most acne and blackhead treatments require patience. It can take three months to see improvement, and consistency is key. Retinoids: Retinoids can help address the oil production and dead skin buildup that cause blackheads.
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.
Acne products typically last four to six months. Common ingredients like salicylic acid and benzoyl peroxide break down rather quickly once exposed to air and may cause more irritation to the skin.
For warts—Repeat one or two times a day as needed for up to 12 weeks, or as directed by your doctor, until wart is removed. For corns and calluses—Repeat one or two times a day as needed for up to 14 days, or as directed by your doctor, until the corn or callus is removed.
Benzoyl peroxide is an active ingredient that is a little more powerful than salicylic acid, and works to penetrate the pores by breaking down the dead skin cells.
Use Products With Salicylic Acid
One go-to ingredient for eliminating blackheads is salicylic acid, a beta hydroxy acid that increases cell turnover and unclogs pores, says Saedi. Suozzi adds that the acne treatment can help dry active acne lesions because it is a mild chemical irritant.
Exfoliate. Use an exfoliating scrub on the skin once a week to help remove the dead skin cells that contribute to blackheads. A scrub may also improve the overall appearance of the skin. Avoid exfoliating if it irritates the skin, and stop using a scrub if it makes the skin feel dry or sore.
Via Refinery29, Elizabeth Tanzi, M.D., agrees that after the clay mask brings all the junk to the surface, physical massage can "indeed dislodge clogged pores and whatever's inside them."
