How to treat acne dark marks ?
"The discoloration from dark marks will usually fade over time," says dermatologist Sejal Shah, MD, who notes that they tend to take between 3-6 months to go away on their own. "But, there are a number of treatment options to help speed up the process."Sunscreen: "Sun exposure during an active breakout can lead to darkening of inflammatory lesions, prolonging their appearance on your skin and making them harder to fade over time," says Dr. Shereene Idriss from Union Square Dermatology, which means it's important to lather on the sunscreen daily — even when it's cloudy. And don't worry about breaking out from a pore-clogging sunscreen; the latest formulas are more innovative and acne-friendly than ever. Elta MD UV Clear Broad-Spectrum SPF 46 is a top derm-approved favorite. It contains niacinamide, which is an anti-inflammatory that helps reduce redness.
Topical vitamin C serum: "Vitamin C serums block abnormal pigment production and can brighten spots that have already developed," says Dr. Zeichner. "They can be layered underneath your sunscreen in the morning." These serums can also help build collagen and promote healing, says says Dr. Shah, who suggests trying "SkinCeuticals C E Ferulic to do the trick.
Retinoids:
"Retinoids work over time by continuously increasing cell turnover which in turn helps fade hyperpigmentation," says Dr. Idriss. Dr. Shah agrees, noting that Retin-A helps with acne marks by causing your skin cells to "divide more rapidly and pushing out cells with discolored pigments." Since retinoids make your skin super-sensitive to the sun, it's best to not only wear SPF, but to also apply a treatment like RoC Retinol Correxion Sensitive Night Cream before you go to bed.
Chemical peels: "A chemical peel is a treatment that uses the application of mild solutions for skin refinement and regeneration. Products containing glycolic acid promote cell turnover, which is the process where new skin cells form and help even out your skin tone," says Dr. Bowe. You can try an at-home peel like Peter Thomas Roth 40% Triple Acid Peel, which uses both glycolic and salicylic acids to help fade spots by exfoliating dead skin cells and smoothing out skin texture. "Or, your dermatologist can prescribe you a stronger peel based on your skin type and treatment goals," says Dr. Bowe.
Dermarolling: Those little needle rollers you've been seeing all over social media? Turns out, they're good for more than just a cute Instagram video. "Microneedling works by creating a small 'injury' to the skin, which in turn can increase collagen and elastin production, improving scars and fine wrinkles and reducing hyperpigmentation," explains dermatologist and founder of Curology, David Lortscher, MD. Use the microneedler a few times a week as a part of your nighttime routine after cleansing and before toning. "It’s particularly important to pay attention to sterility, and remember that overdoing can damage the skin and incite inflammation, so proceed with caution if you are considering home treatments. Consider a consultation with a dermatologist to explore in-office options,"
