Sun Spots, Dark Spots, and Hyperpigmentation: What Are They? And How to Protect Your Skin.

Sun Spots, Dark Spots, and Hyperpigmentation: What Are They? And How to Protect Your Skin.

Summer is when your skin gets to show off. Longer days, more time outdoors, that natural glow starting to peek through. But there's one thing that can throw off an otherwise gorgeous summer complexion: pigmentation.

At Skin & Tonic Raleigh, we love this time of year because it's actually the best window to get ahead of sun spots, dark marks, and uneven tone before they have a chance to set in. The clients who understand what's driving their pigmentation, and treat it strategically, are the ones who walk into fall with the clearest, brightest skin of the year.

So let's talk about what hyperpigmentation is, why summer plays such a big role, and exactly how to keep your skin glowing all season long.

What is Hyperpigmentation?

Hyperpigmentation is a catch-all term for any area of skin that appears darker than the surrounding skin. It happens when melanin (the pigment that gives skin its color) is produced in excess in certain areas.

There are a few different types of hyperpigmentation, and knowing which one you're dealing with makes all the difference when it comes to treating it:

Sun spots (also called solar lentigines or liver spots) are flat, brown or tan patches that appear on areas with repeated sun exposure. Think cheeks, the bridge of the nose, hands, and forearms. They tend to deepen every summer and fade slightly in winter, which is your skin literally showing you the sun's cumulative impact.

Post-inflammatory hyperpigmentation (PIH) is the dark mark left behind after a breakout, a scratch, or any kind of skin trauma. It's especially common in deeper skin tones and can linger for months if not addressed properly.

Melasma is hormonal in origin, often triggered by pregnancy, birth control, or hormonal fluctuations, and made significantly worse by UV exposure. It usually appears as larger, symmetrical patches across the forehead, cheeks, and upper lip.

Did you know that all three can overlap? Many clients have more than one type of hyperpigmentation happening at the same time which is exactly why a one-size-fits-all approach to treating pigmentation rarely works.

Why does summer make hyperpigmentation worse?

Melanin is your skin's built-in defense system. When UV rays hit the skin, melanocytes (the cells responsible for producing melanin) are stimulated to protect you. For most people, that produces a tan. For skin that already has pigmentation concerns, it produces more uneven color, deeper spots, and a patchwork effect that feels impossible to control.

The tricky part is that the damage often isn't visible right away. Unlike sunburn which shows up right away, UV exposure builds up slowly over time, with the damage often going unnoticed for months. By the time you do notice, the melanin has already been stimulated and deposited in the deeper layers of skin. That's why waiting until dark spots appear to start treating them will have you playing catch up.

Summer also brings more heat, and heat independently stimulates melanin production. So even on a cloudy day, even with incidental exposure from driving or sitting near a window, pigmentation can deepen.

What are the best treatments for hyperpigmentation?

Effective hyperpigmentation treatments work on two levels: First, they suppress melanin production at the source. Second, they help clear existing pigment from the skin. When you only do one without the other, results are slow and inconsistent.

Here is what we reach for at Skin & Tonic:

Targeted exfoliation is the foundation. You cannot fade what you cannot resurface. Gentle but consistent exfoliation encourages cell turnover, which helps bring newer, clearer skin to the surface over time. The key word is consistent. Occasional exfoliation doesn't give results. Regular exfoliation is what makes a real difference. The Laser Serum from Lenox and Sixteenth is one of our current favorites for exactly this reason. Its triple acid concentrate (glycolic, lactic, and mandelic) resurfaces and clarifies without aggravating sensitive or reactive skin.

Melanin-inhibiting ingredients go to the source to help minimize the problem. Think Vitamin C, mandelic acid, glycolic acid, and niacinamide. These ingredients interrupt the chain of events that leads to excess melanin production, helping prevent hyperpigmentation.

Sheet masks are massively underrated for pigmentation. Masque PIGM400 from Biologique Recherche is a product we recommend constantly, and it earns that recommendation every time. Easy to use, visible results, and it works for virtually every skin type. It's one of the best ways to give your skin a concentrated dose of brightening actives at home between treatments.

Professional treatments are a game changer. Our DermaSweep Exfoliating Treatment uses the DermaSweep machine to deeply exfoliate and infuse melanin-inhibiting serums directly into the deeper layers of the skin. Paired with professional masking, the results are significantly faster than home care alone. If summer pigmentation is something you deal with year after year, then be sure to bring it up with your esthetician.

The role of SPF in preventing hyperpigmentation

We will say this every month until it sticks: treating pigmentation without daily sun protection is like mopping the floor with the tap still running.

Every brightening serum, every professional treatment, every at-home mask you invest in is going to be far less effective if your skin is getting unprotected UV exposure. SPF is not just prevention. For anyone dealing with active pigmentation, it is part of the treatment.

We recommend a zinc-based mineral sunscreen with SPF 50, used every single morning, reapplied if you're spending time outdoors (including in the car). Look for formulas that also include HEV protection, because high-energy visible light (the kind emitted by screens, not just the sun) can also trigger melanin production.

The good news is that mineral sunscreen has come a long way. The days of white cast and heavy texture are largely behind us. There are beautiful, wearable options that sit well under makeup and feel good on the skin. Our favorites are Solara Suncare and Suntegrity.

When should you start treating hyperpigmentation?

If you want your skin to look noticeably clearer by the end of summer, the time to start is now!

The earlier in the season you can start working on suppressing melanin activity, staying consistent with protection and prioritising targeted home care, and booking a treatment or two before peak summer heat means you're working with the skin's natural cycle rather than chasing it.

One more thing: if you've been dealing with pigmentation for years and feel like nothing has made a real dent, please come in and talk to us. Pigmentation is one of the most treatable skin concerns we see, but it does require a customized plan and consistency. Generic products and inconsistent routines are usually why results stall.

Your skin is capable of so much more than you think. It just needs the right support to look its best all year ‘round.

Stay glowing, Robin & Lori
