Brown Spots After Summer? What They Are—and What You Can Do About Them

Summer may be over, but for many people, it leaves something behind: new brown spots on the face, chest, shoulders, and hands. If you’ve noticed extra freckling or darker patches since your last beach trip, you’re not imagining it—and you’re not alone.

Many causes of brown spots are harmless, but not every new or changing spot is simply sun damage. The more important news is that they’re not all the same thing and figuring out which type you have is the first step to treating it safely and effectively.

What’s Actually Causing Those Brown Spots?

“Brown spot” is a catch-all term. Dermatologists actually distinguish between several different types of pigmentation, each with its own cause and treatment path.

Freckles (Ephelides)

Freckles are small, flat, light-to-medium brown spots that tend to run in families and show up most in people with fair skin. They darken with sun exposure and often fade on their own once summer ends. Freckles themselves aren’t harmful, but sun exposure can make them darker or more noticeable—another reason consistent sun protection matters.

Sunspots (Solar Lentigines)

Sometimes called age spots or liver spots, solar lentigines are larger, flatter, and more persistent than freckles. They’re caused by cumulative sun exposure over years, not just one summer, and they typically don’t fade with the seasons the way freckles do. These are the spots patients usually mean when they say a new mark “just showed up and won’t go away.” They’re most common on the face, backs of the hands, shoulders, and chest.

Melasma

Melasma tends to appear as larger, symmetrical, blotchy patches—often across the cheeks, forehead, upper lip, or jawline. Sun and visible-light exposure can trigger or worsen melasma, and hormonal factors such as pregnancy, oral contraceptives, or hormone therapy may also play a role. This distinction matters because melasma responds differently to treatment than sunspots, and some procedures can worsen pigmentation if they aren’t selected and performed appropriately.

Other Causes of Pigmentation

Brown marks can also result from post-inflammatory hyperpigmentation (dark marks left behind after acne, a bug bite, or a skin injury). Certain medications, or, less commonly, be an early sign of something that needs closer attention.

Why an Accurate Diagnosis Matters

It’s tempting to treat every new brown spot the same way—especially with so many over-the-counter serums and DIY spot treatments on the market. But that approach can backfire:

• Melasma treated like a sunspot can become more irritated and more resistant to treatment.
• A changing or irregular spot could be something other than sun damage, including a pigmented lesion that warrants a biopsy. Any spot that is new, growing, changing color or shape, or bleeding should always be evaluated by a board-certified dermatologist before any cosmetic treatment is considered.
• Skin tone matters. Certain treatments carry a higher risk of rebound pigmentation in darker skin tones if not selected and calibrated correctly.

A dermatology evaluation typically starts with an examination of the area and a conversation about how long the spot has been there, whether it has changed, and what may have triggered it. That’s what determines the right treatment plan—and rules out anything that needs more than a cosmetic fix.

Treatment Options for Brown Spots and Pigmentation

Once a diagnosis is confirmed, your dermatologist may recommend one or more approaches based on the type of pigmentation, your skin tone, medical history, and treatment goals.

Topical Therapies

Topical treatments are often an important part of managing pigmentation, particularly melasma and some forms of sun-related discoloration. Depending on the diagnosis, your dermatologist may recommend prescription or over-the-counter options such as:

• Hydroquinone — a depigmenting agent that helps reduce excess pigment production, typically used in short, monitored courses
• Retinoids — increase skin cell turnover and help fade discoloration over time while improving overall texture
• Vitamin C and azelaic acid — antioxidant and brightening ingredients that can be used alongside prescription treatments or as gentler maintenance options
• Daily sun protection — Broad-spectrum SPF 30+ is an essential part of managing pigmentation and helping prevent recurrence. For melasma, your dermatologist may also recommend a tinted sunscreen containing iron oxides, which can help protect against visible light that may worsen melasma.

Chemical Peels

Chemical peels use a controlled exfoliating solution to remove the outer, pigmented layers of skin, encouraging fresher, more evenly toned skin underneath. Superficial and medium-depth peels are commonly used for sunspots and mild-to-moderate discoloration, and are often done in a series for gradual, controlled improvement. Peel type, strength, and frequency should be carefully selected based on your skin type and pigmentation concerns, as overly aggressive treatment can sometimes trigger post-inflammatory hyperpigmentation or worsen existing discoloration.

Laser and Light-Based Treatments

For sunspots and freckling that haven’t responded to topicals, laser and light treatments can target pigment more directly:

• IPL (intense pulsed light) — may help address diffuse sun-related pigmentation and freckling in appropriately selected patients
• Q-switched and picosecond lasers — target concentrated pigment in solar lentigines
• Fractional lasers — may be considered when pigmentation occurs alongside concerns such as uneven texture or signs of photoaging

Laser treatment for melasma is more nuanced; some laser and light-based treatments can worsen melasma or contribute to post-inflammatory hyperpigmentation. This is a case where working with a provider who can distinguish melasma from sun damage isn’t just about better results—it’s about avoiding a setback.

The Bottom Line

Not every brown spot is created equal, and not every treatment is right for every type. The right approach starts with an accurate diagnosis from a board-certified dermatologist, followed by a treatment plan tailored to your specific type of pigmentation, skin tone, and goals.

If summer left its mark on your skin, fall can be a convenient time to talk with a dermatologist about your options. Depending on your diagnosis, skin type, and goals, your dermatologist can determine whether topical treatments, chemical peels, laser or light-based treatments, or another approach may be appropriate. Consistent sun protection remains essential year-round.
