After the summer months, especially during a high-heat year like this one, hyperpigmentation issues like dark spots, age spots and melasma show up more prominently in the fall than in any other season. Even if you’ve done your due diligence shielding your skin from UV rays, hyperpigmentation can ramp up from being outdoors, in front of screens, relaxing in saunas, and even taking long, hot showers. Before throwing in the towel on brighter, eventoned skin, try these expert-approved solutions.
Mischievous Melanocytes
“There are many causes of hyperpigmentation,” says Aventura, FL dermatologist Dr. Bertha Baum. “Melanin production can be overstimulated by exposure to UV radiation, as well as genetics, hormonal changes and any inflammatory condition.” While overactive melanocytes are the widely known culprits for increased darkening, there is also a vascular component, adds New York dermatologist Orit Markowitz, MD. “Recent studies have shown that hyperpigmentation is very much associated with an increase in vasculature. In terms of treatment, we’re not only treating the pigment; we’re also targeting swollen blood vessels. Therefore, it’s not unreasonable to think that long, hot showers and other types of heat exposure can exacerbate hyperpigmentation, but again, the biggest factor is UV exposure.”
01: Protection Correction
Celebrity aesthetician Tammy Fender says the best offense is a good defense. Even though summer is over, protecting your skin from further damage is the best thing you can do to decrease the appearance of dark spots. “The more physical blocks the better,” she notes. “Any SPF that has some form of a mineral, physical block will work, but to be doubly sure, add a little bit of micronized zinc oxide to your daily cream.” After treating her own hyperpigmentation issues for years, Fender’s first recommendation to clients is to choose a mineral, not chemical, sunblock. “I follow this with treatments that remineralize the skin and slough off dead surface cells in order to constantly create new cell renewal.”
02: Cysteamine Cream
While vitamin C, arbutin, hydroquinone and acid-based products are known dark spot correctors, cysteamine has become a superstar ingredient for safe, effective brightening on all skin types. “It inhibits the enzyme pathway responsible for melanin production,” explains Denver dermatologist Joel Cohen, MD. Cysteamine can target dark spots and patches without the potential carcinogenic risks associated with hydroquinone. “Senté’s Cysteamine Corrector has a more stable form of vitamin C called THD ascorbate, as well as niacinamide and Heparan Sulfate Analog to increase moisture and reduce inflammation and redness,” he adds. Other options featuring the lightening ingredient include the Cyspera Intensive System by Scientis ($299) and Urban Skin Rx Hypercorrect Intense Fading Cream ($48).

Using Senté’s Cysteamine HSA Pigment & Tone Corrector for 15 minutes a day over 16 weeks, this 53-year-old woman saw stubborn dark spots on her face lighten and she achieved a more even-toned complexion.
03: Tranexamic Acid
One derm-approved approach is using compounded, medicated creams that contain tranexamic acid, which also slows the production of melanin, to boost results. “Its anti-melanogenic properties target hyperpigmenation, which helps reduce symptoms,” says Dr. Markowitz. Dr. Baum says she uses the powerful ingredient three different ways: “Injected via AquaGold microinfusions; topically in compounded creams I prepare; or taken orally for severe melasma cases that are hard to treat.”
