Sun spots
The receipts of cumulative UV exposure: discrete, stable marks on the cheeks, temples, hands, and chest after years of Houston sun. They rarely fade on their own, but they respond well to targeted treatment.
Houston condition plan
Dark Spots, Sun Spots, and Uneven Tone
Dark spots have a way of making skin feel older than it is. They show up after breakouts, summers, pregnancy, or years of Houston sun, then seem to ignore the products that promised to fade them. The reason is usually not the product. It is that nobody diagnosed which kind of pigment you actually have.

The short version
Dark spots is one word for three different problems: sun spots, post-acne marks, and melasma. Each responds to a different plan.
IPL can clear a sun spot quickly and make melasma worse. Diagnosis comes before the device.
Most plans correct the field with ZO home care and peels, then clear stubborn spots with Lumecca IPL when candidacy fits.
Daily SPF is part of the treatment itself. Houston sun will rebuild whatever you correct without it.
What's actually happening
Hyperpigmentation is one word for at least three different problems, and they respond to different treatments. Houston's UV index keeps a thumb on the scale for all of them: a pigment plan here has to treat the existing pigment and interrupt the daily re-tanning of every spot you are trying to fade. That is why prevention is built into the treatment itself, not offered as an afterthought at checkout.
The receipts of cumulative UV exposure: discrete, stable marks on the cheeks, temples, hands, and chest after years of Houston sun. They rarely fade on their own, but they respond well to targeted treatment.
The mark left behind after a breakout, bug bite, or overly aggressive treatment. The injury heals, but the pigment memory lingers, especially in medium and deeper skin tones.
A hormonally driven, trigger-reactive condition that behaves like a chronic process rather than a mark. If this sounds like you, start with the melasma treatment page.
Many patients have two types at once, which is why a single product or single device rarely clears everything and a mapped plan does.
Why the usual fixes fail
The common mistake is treating every brown mark the same. Diagnosis is what prevents wasted months and wasted money, because the best treatment for one pigment type can be useless or harmful for another.
A brightening serum with a real ingredient at a real concentration may help one type of pigment and barely touch another.
IPL can be the perfect tool for a sun spot and the exact wrong tool for melasma, where heat can darken the condition instead of clearing it.
Aggressive exfoliation creates new inflammation, which creates new pigment — the exact cycle the treatment was supposed to break.
A drawer of half-used correctors, each abandoned at week three. Most were not wrong, they were underpowered, unprotected by SPF, or aimed at the wrong pigment type.
How we treat it
The plan starts with pattern recognition: your provider maps where the pigment sits, how it behaves seasonally, and what caused it, because sun spots, PIH, and melasma each get a different protocol. From there, most Brightening Plans run on parallel tracks.
A provider-selected ZO regimen pairs pigment-regulating ingredients with cell-turnover support at physician-grade concentrations, introduced in sequence so the skin adapts without inflaming.
A series of chemical peels speeds the turnover of pigmented cells, spaced four to six weeks apart and timed to Houston's sun calendar.
For confirmed sun damage in qualified patients, Lumecca IPL hits the pigmented lesions directly — spots that ignored years of topicals often respond in one to three sessions.
Advanced, widespread sun damage with texture change may expand the conversation to laser resurfacing or a physician-performed controlled depth peel.
Topical and peel-based correction is measured in weeks, with most patients seeing meaningful brightening across an 8 to 12 week program. IPL results on true sun spots can appear faster, often within a session or two. Either way, the result is protected by daily SPF and pigment-aware maintenance, because Houston will happily rebuild what you just corrected.
"The biggest change was learning which spots were sun damage and which ones needed a different approach."
Go deeper
A sun spot is a stable mark: treat it, protect it, and it tends to stay gone. Melasma is a process: an overactive pigment response that re-darkens with heat, hormones, and light, even after it has been visibly cleared. The treatments that clear sun spots fastest, IPL and lasers, are heat-based, and heat is a melasma trigger. This single fact explains most pigment-treatment regret we see from other clinics.
If your pigment is patchy and symmetric across the cheeks or upper lip, darkens every summer, or appeared with pregnancy or birth control, read the melasma treatment page before booking any light-based treatment. If your spots are discrete, scattered, and stable where the sun hits, you are probably on the right page.
They solve the problem from different directions. Lumecca IPL targets pigmented lesions with light: the spot darkens, lifts, and flakes away over a week or two, which makes it efficient for discrete sun spots on lighter to medium skin tones. Chemical peels work broadly: they accelerate turnover across the whole treated area, improving overall tone, texture, and diffuse pigment rather than sniping individual spots.
Many Houston plans use both: peels and home care to correct the field, IPL to clear the stubborn individual marks. The order and mix depend on your skin tone, pigment type, and season, which is what the consultation is for.
PIH fades on its own schedule, and everything that irritates the skin resets the clock: picking, aggressive scrubs, high-strength acids layered too fast, and unprotected sun exposure. The plan for post-acne pigment is deliberately two-track: calm and control the active breakouts first (see our adult acne treatment page), then correct the marks with pigment-regulating topicals, gentle peels, and disciplined SPF. Patients who try to fade marks while still breaking out are refilling the bucket while draining it.
Medium and deeper skin tones are both more prone to hyperpigmentation and more vulnerable to pigment injury from aggressive treatment. An IPL setting, peel depth, or laser choice that is routine for one skin type can cause new pigment in another. That is not a reason to avoid treatment; it is a reason to sequence it correctly: topical preparation first, conservative peel depths, device settings selected for your skin type, and a provider who will say no to a treatment that carries more pigment risk than pigment benefit.
What it costs
Brightening plans vary by product regimen and whether the series uses peels, IPL, or both. The consultation is complimentary when booked through our Houston clinic booking flow. You leave with a written plan either way.
Book NowWhy ZO Houston
A ZO Skin Centre is different because the visit starts with a plan, not a menu. Your provider reviews skin behavior, tolerance, products, timing, and goals before recommending treatment. We use physician-grade ZO protocols, document the plan clearly, and tell you no when a service is not the best fit.
No, and the difference changes the entire plan. Sun spots, post-acne marks, and melasma can look nearly identical in a bathroom mirror but respond to completely different treatments. Melasma in particular can worsen with heat-based devices that work well on sun spots.
It depends on the type of spot. A true sun spot may respond quickly to Lumecca IPL in a qualified patient, while post-acne marks usually need topical correction and patience. Picking the fast option for the wrong pigment type is how patients lose months.
Post-inflammatory marks can fade over months if nothing keeps re-triggering them, though Houston sun usually slows that down. Sun spots and melasma rarely resolve on their own and typically need active correction.
Not always. Many pigment plans get most of their result from ZO home care, chemical peels, and disciplined SPF. Devices are added when the pigment type, skin tone, and season make them a safe accelerator rather than a gamble.
IPL can be excellent for selected sun damage and uneven tone, and it is one of the most-requested treatments for Houston sun history. It is the wrong tool for melasma in many patients, which is why diagnosis comes before the device.
Yes, with pigment-safe planning. Deeper skin tones carry a higher risk of post-inflammatory pigment from aggressive treatments, so device settings, peel depths, and topical strength are chosen for your skin type rather than copied from a menu.
Daily broad-spectrum SPF, pigment-aware maintenance products, and seasonal planning are the backbone. Correction without prevention is how patients end up repeating the same program every year.
Pricing depends on the product regimen and whether the plan uses peels, IPL, or both. The consultation is complimentary when booked through our Houston clinic booking flow, and you leave with a written plan either way.
