If you live in Florida long enough, your skin keeps a record of it. Brown spots on the cheeks, a dusty patch across the forehead, a freckle that used to be one and is now a cluster. Most of it traces back to one thing: light. This guide from Olympia Aesthetics & Wellness walks through what pigmentation actually is, the main types we see, why the Palm Harbor sun accelerates all of them, and the treatment paths that genuinely help.

What Hyperpigmentation Actually Is
Your skin color comes from melanin, a pigment made by cells called melanocytes. When those cells get triggered, they produce extra melanin and hand it off to the surrounding skin cells. That surplus pigment shows up as a spot, a patch, or an overall unevenness. The trigger matters, because it changes both the pattern you see and the treatment that works.
The big three triggers are ultraviolet light, inflammation, and hormones. Often more than one is at play at the same time, which is part of why discoloration can be stubborn.
The Main Types of Pigmentation
Not all brown spots are the same, and calling everything a “sun spot” leads to the wrong treatment. Here’s how we sort them.
Sun Spots (Solar Lentigines)
These are the flat, well-defined brown spots that collect on the face, chest, shoulders, and backs of the hands. They’re a direct signature of cumulative sun exposure. Research points to a chain reaction where UVB light prompts skin cells to release growth signals that ramp up pigment production over time [1]. Sun spots tend to respond well to light-based and laser treatments.
Melasma
Melasma shows up as larger, blotchy patches, usually symmetric across the cheeks, forehead, and upper lip. It’s driven by a mix of sun, hormones, and inflammation, often with a genetic tendency behind it [2]. Pregnancy, birth control, and hormone shifts are common triggers. Melasma is the most temperamental type. It can flare with heat and light, and aggressive lasers can actually make it worse, so it needs a careful, conservative plan.
Post-Inflammatory Hyperpigmentation (PIH)
This is the mark left behind after the skin has been inflamed. Acne, a bug bite, a scratch, a burn, even a too-aggressive cosmetic treatment can leave a flat brown or tan spot once the original problem heals. PIH is more common and more persistent in deeper skin tones, and it can take months to fade on its own [3]. Because inflammation is the root cause, calming the skin is as important as treating the pigment.
Freckles (Ephelides)
Freckles are small, tan spots that show up in sun-exposed areas and tend to darken in summer and fade in winter. They’re largely genetic and generally harmless. Many people like them. When freckles bother someone cosmetically, they respond to the same light-based approaches used for sun spots.
Comparison at a Glance
| Type | What it looks like | Main drivers | Where it shows | Treatment note |
|---|---|---|---|---|
| Sun spots (lentigines) | Flat, defined brown spots | Cumulative UV | Face, chest, hands | Responds well to IPL and laser |
| Melasma | Blotchy symmetric patches | UV, hormones, inflammation, genetics | Cheeks, forehead, lip | Needs conservative, layered care |
| PIH | Flat brown or tan marks after inflammation | Prior acne, injury, irritation | Anywhere skin was inflamed | Calm the skin first, treat gently |
| Freckles | Small tan spots, seasonal | Genetics plus UV | Sun-exposed areas | Optional, treats like sun spots |
If you’re not sure which one you’re dealing with, that’s normal. Telling them apart is one of the first things we do at a consultation, and it changes everything about the plan.
Why Florida Sun Makes It Worse
Palm Harbor, Clearwater, Dunedin, Tarpon Springs, and the rest of Tampa Bay sit under strong, year-round sun. That matters for pigmentation in a few specific ways.
Ultraviolet light directly stimulates melanocytes to make more pigment, which is the core mechanism behind sun spots and a major aggravator of the other types [1]. It’s not only UVB, the burning wavelength. Longer-wavelength UVA and even visible light penetrate deeper and can drive melasma, which is why ordinary sunscreen sometimes isn’t enough for pigment-prone skin [2][4].
There’s also a compounding effect. Chronic exposure feeds low-grade inflammation and oxidative stress in the skin, and that inflammatory background keeps the pigment machinery switched on [3]. In a place where you’re getting incidental sun most days of the year, driving, walking to the car, at the beach, that low simmer never really stops. This is why sun protection isn’t an add-on to pigment treatment. It’s the foundation the rest is built on.
Overview of Treatment Options
There’s no single fix for pigmentation. The right plan depends on which type you have, your skin tone, and how deep the pigment sits. Here are the main categories we work with.
IPL and photofacials. Intense pulsed light targets the brown pigment in sun spots and freckles, breaking it up so the skin clears it. It’s a strong first choice for classic sun damage on lighter skin. It is not the right tool for melasma, where it can backfire.
BBL BroadBand Light. BBL is a refined, medical-grade form of pulsed light. At Olympia we use the Sciton BBL platform to address sun spots and overall tone across the face, chest, and hands. Learn more on our BBL page.
HALO and MOXI laser. These are fractional lasers that resurface the skin and improve pigment along with texture and tone. HALO is a stronger treatment for more advanced sun damage, while MOXI is a gentler option that suits a wider range of skin tones and works well as maintenance.
Chemical peels. Peels exfoliate pigmented surface cells and can be tuned in strength. They’re useful for PIH and general dullness, and they’re often a safer starting point than laser for melasma-prone or deeper skin. See our VI Peel and laser peel options.
Topicals. Prescription and cosmeceutical ingredients that slow pigment production or speed cell turnover do real work, especially for melasma and PIH. They’re frequently the backbone of a melasma plan and a maintenance layer after any in-office treatment.
Sun protection. Daily broad-spectrum SPF, and for melasma a tinted mineral sunscreen that also blocks visible light, protects your results and prevents new spots [4]. Nothing else on this list holds up without it.

When to See a Provider
A lot of mild discoloration can be managed with good sunscreen and a solid skincare routine. It’s worth booking a professional evaluation when:
- A spot is changing in size, shape, or color, or looks different from your others. That’s a dermatology and skin-cancer question first, and we’ll refer appropriately.
- Over-the-counter products haven’t moved the needle after a few months.
- You have melasma, which rarely responds well to guesswork and can worsen with the wrong treatment.
- The discoloration is affecting how you feel about your skin and you want a real plan.
The value of a consultation is getting the diagnosis right before spending money on treatment. Sun spots, melasma, and PIH can look similar and need different approaches.

Frequently Asked Questions
What’s the difference between sun spots and melasma?
They look related but behave like different conditions. Sun spots, medically called solar lentigines, are flat, sharply bordered individual brown spots caused by cumulative UV exposure. They sit near the surface and respond very well to light-based treatments like BBL, often clearing within a couple of sessions. Melasma shows up as larger, blotchy patches, usually symmetric across the cheeks, forehead, or upper lip, and it is driven by a mix of sun, hormones, and inflammation, often with a genetic tendency behind it. That difference changes everything about treatment: the aggressive heat and light that clears sun spots can actually make melasma worse. Telling the two apart is one of the first things we do at a consultation, because getting the diagnosis right protects you from paying for the wrong treatment.
Can hyperpigmentation be cured permanently?
Most pigmentation can be improved substantially, but permanent is the wrong promise for skin that still lives under Florida sun. The realistic picture varies by type. Sun spots respond well to light-based treatment and can stay clear for years with daily sun protection and occasional maintenance sessions. Post-inflammatory hyperpigmentation usually fades fully once the pigment is cleared and the underlying inflammation is controlled. Melasma is different: the pigment cells stay primed to overreact to sun, heat, and hormones, so it behaves like a condition you manage rather than a problem you erase, and anyone promising a permanent melasma cure is overselling. What we can honestly offer is significant, visible fading and a maintenance routine that keeps it faint, which for most patients is the difference that matters.
Does sunscreen really matter if the damage is already done?
Yes, and arguably it matters more once you are treating existing damage. UV and even visible light keep stimulating your melanocytes every single day, so without daily broad-spectrum protection, new spots keep forming and the ones you paid to treat come back. Research on melasma in particular shows visible light contributes to pigment, which is why we often recommend a tinted mineral sunscreen with iron oxide for pigment-prone skin. The tint blocks visible wavelengths that plain sunscreen misses. Think of it this way: treatments clear the pigment record your skin has already written, and sunscreen stops it from writing a new one. Every result we produce, whether from BBL, MOXI, HALO, or a peel, holds up dramatically better in patients who protect their skin daily.
Why does my discoloration get worse in summer?
Because ultraviolet light is the main fuel for pigment production. More sun means more melanin, and summer brings more of everything that drives discoloration: stronger UV, more time outdoors, and more heat, which is a trigger of its own for melasma. Freckles and melasma in particular darken noticeably in the warmer months and fade somewhat in winter. Florida barely gives pigment-prone skin an off-season, since the UV index around Palm Harbor and Clearwater stays high most of the year. That is why we treat sun protection as the foundation of every pigment plan: daily broad-spectrum sunscreen, reapplied when you are outdoors, plus hats and shade during peak hours. Consistent protection through every season, not just summer, is what keeps July from undoing your progress.
Is laser safe for darker skin tones?
It can be, but device choice and settings matter far more than they do for lighter skin. Some lasers and IPL deposit enough heat that deeper skin tones face a higher risk of post-inflammatory hyperpigmentation, the very problem you came in to fix. Non-ablative options like MOXI at conservative settings have published support for use in medium and darker skin, and carefully chosen chemical peels are often a safer starting point than light-based treatments. The honest answer is that candidacy gets decided face to face, not from a website. We assess your skin tone, history, and goals before recommending any device, and we would rather steer you to a gentler plan than risk trading brown spots for new ones.
How long until I see results?
It depends on the treatment and the type of pigment. Sun spots treated with BBL or IPL usually darken into small coffee-ground specks within a day or two, then flake away over the following week, so visible clearing often shows within two weeks. Fractional lasers like MOXI and HALO reveal brighter skin after a short shedding phase, with continued improvement over one to three months as collagen rebuilds. Melasma and post-inflammatory hyperpigmentation move on a slower clock. Those respond to a layered plan of topicals, sun protection, and gentle in-office care, and meaningful fading typically takes weeks to months of consistency. At Olympia Aesthetics in Palm Harbor we map out the expected timeline at your consultation, so you know what to watch for at each stage instead of guessing.
