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?
Sun spots are flat, individual brown spots from cumulative UV exposure and usually respond well to light and laser treatments. Melasma is a blotchy, symmetric patch driven by a mix of sun, hormones, and inflammation, and it needs a gentler, more layered plan because aggressive treatment can make it worse.
Can hyperpigmentation be cured permanently?
Most pigmentation can be improved significantly, but “permanent” is the wrong word for skin that still lives in the sun. Sun spots can clear well and stay clear with protection. Melasma tends to be a managed condition rather than a one-time fix. Ongoing sun protection is what keeps results.
Does sunscreen really matter if the damage is already done?
Yes. UV and visible light keep stimulating pigment every day, so without daily broad-spectrum protection, new spots form and treated ones return. For pigment-prone skin, a tinted mineral sunscreen adds a layer against the visible light that plain sunscreen misses [4].
Why does my discoloration get worse in summer?
More sun means more melanin. Melasma and freckles in particular darken with increased exposure and heat. Florida’s year-round sun means pigment-prone skin needs consistent protection through every season, not just summer.
Is laser safe for darker skin tones?
It can be, with the right device and settings. Some lasers and IPL carry a higher risk of post-inflammatory hyperpigmentation in deeper skin tones, so treatment selection matters. Gentler options like MOXI and carefully chosen peels are often safer starting points. This is exactly the kind of decision a consultation sorts out.
How long until I see results?
It varies by treatment and pigment type. Sun spots often show visible clearing within a week or two after light-based treatment as the pigment darkens and flakes away. Melasma and PIH improve more gradually over weeks to months, since the goal there is calming the skin, not forcing it.
