Hyperpigmentation and uneven skin tone are most often the result of cumulative sun exposure, though acne, injury, and hormonal changes can contribute too. Years of UV exposure trigger the skin to overproduce melanin in some areas more than others, leaving behind dark spots, patches, or an overall tone that looks blotchy rather than even.
Addressing it usually means combining a professional treatment that targets the pigment directly with daily sun protection that keeps new damage from forming. No single at-home product undoes years of sun exposure on its own. That's the gap in-office treatments are built to close.
Hyperpigmentation happens when skin produces excess melanin, the pigment responsible for skin color, in response to a trigger. UV exposure is the most common trigger by far: ultraviolet light stimulates melanin-producing cells (melanocytes) to work harder, and over years of repeated exposure, that overproduction shows up as sun spots, patches of darker skin, or an uneven tone across the face.
Sun exposure isn't the only cause, but it's the dominant one. Post-inflammatory hyperpigmentation develops after the skin experiences inflammation or injury: acne breakouts, cuts, burns, or aggressive extractions can all leave behind a dark mark once the original irritation has healed.
Hormonal changes, including pregnancy and certain medications, can also trigger a related pattern of pigmentation known as melasma, which tends to appear as larger, symmetrical patches rather than isolated spots.
These causes of hyperpigmentation and uneven skin tone can overlap. A patient with years of sun exposure and a history of acne may be dealing with both sun-triggered pigment and post-inflammatory marks at the same time, which is part of why an individualized treatment plan matters more than a single fix. What looks like one uneven-tone concern often has more than one contributing cause, and the treatment approach that works best depends on which cause is doing the most damage.
Regardless of the trigger, the underlying mechanism is the same: melanocytes deposit pigment unevenly, and that pigment sits in the skin until something either breaks it down or the skin sheds it away naturally over time. Professional treatments work by speeding up that process in a way at-home products generally can't replicate.
Anne Therese Aesthetic Medicine offers three in-office treatments that address hyperpigmentation and uneven skin tone, each working through a different mechanism. A licensed medical professional determines which one, or which combination, fits a patient's skin during a consultation.
IPL/BBL photofacial is a light-based treatment that targets pigmented lesions and redness beneath the skin's surface. The device delivers broad-spectrum light that's absorbed by excess pigment and blood vessels, causing the treated areas to darken slightly and then fade as the body clears them over the following days to weeks.
This mechanism makes IPL/BBL a fit for sun-triggered pigmentation specifically: sun spots, areas of broad discoloration, and redness that shows up alongside uneven tone. Because the light targets pigment sitting at a specific depth, it works on the surface-level discoloration that years of sun exposure typically produce, without requiring the skin's surface layer to be removed the way a resurfacing treatment does.
Fraxel laser is a fractional laser resurfacing treatment, performed by a licensed medical professional, meaning it treats the skin in a pattern of microscopic columns rather than the entire surface at once. Each column of treated tissue prompts the surrounding, untreated skin to support faster healing and cell turnover, which brings fresher, more evenly pigmented skin to the surface over time.
Because Fraxel works at a different depth and through a different mechanism than a light-based treatment, it tends to suit uneven tone that involves texture changes alongside pigment, not just discoloration on its own. The fractional approach also means the skin heals in sections, which is part of why recovery differs from a full-surface resurfacing treatment. A provider can speak to what recovery looks like for your specific plan during a consultation. Timing also matters for Fraxel specifically: fall is generally the best time to start a Fraxel laser series after summer sun exposure.
A chemical peel uses a controlled chemical exfoliation to remove the outermost layers of pigmented, sun-damaged skin, encouraging fresher skin to surface underneath. The strength and depth of a peel can be adjusted to the concern being treated, which gives a provider flexibility in matching the treatment to how much pigment needs to be addressed and how much recovery time a patient can accommodate.
Peels tend to work well for more superficial pigmentation and for patients looking for a treatment that can be layered into a broader skincare routine over time. Because a chemical peel works through exfoliation, it's often considered alongside IPL/BBL or Fraxel rather than as a replacement for either, depending on how deep the pigmentation sits. Peel timing also carries its own seasonal considerations, with fall and winter generally preferred.
Severity and depth of the pigmentation matter most: broad, surface-level discoloration responds differently than pigment that's set in more deeply or comes with textural changes. A provider weighs this, along with other factors, during a consultation rather than applying a fixed rule to every patient.
Skin type is a second factor. Certain treatments carry different considerations for deeper skin tones, since higher-energy light and laser treatments can affect melanin-rich skin differently than lighter skin. A licensed medical professional evaluates skin type as part of determining which treatment, intensity, and settings are appropriate before recommending a plan.
Downtime tolerance also factors into the decision. IPL/BBL, Fraxel, and chemical peels differ in how much visible recovery they involve and how long it takes, and a patient's schedule and comfort with visible healing time are part of what a provider considers. Someone who needs to return to normal activity quickly may be steered toward a different starting point than someone who can accommodate a longer recovery window for a more resurfacing-focused result.
Finally, whether the concern is isolated pigmentation or involves multiple contributing causes (sun damage and post-inflammatory marks together, for example) can point toward combining treatments. A provider builds an individualized treatment plan around these factors rather than defaulting to a single treatment for every patient.
Daily sun protection is necessary as part of any hyperpigmentation treatment plan because UV exposure is the primary driver behind most hyperpigmentation. Continued exposure without protection can trigger new pigment production in the same areas a treatment just addressed, working against results before they've had a chance to develop.
Sunscreen also supports the skin while it heals. Treated skin is often more sensitive to UV exposure immediately following a session, which makes consistent daily sunscreen use part of protecting the investment already made in a treatment, not just a preventive habit for the future. Providers generally recommend broad-spectrum sun protection as a daily habit, reapplied through the day, for any patient being treated for pigmentation or uneven tone.
Sun protection doesn't replace professional treatment for pigmentation that's already present: it's what keeps existing treatment results from being undone by the same trigger that caused the original discoloration. Patients who pair a treatment plan with consistent daily sunscreen tend to see results hold longer than those who treat the sunscreen step as optional.
Patients dealing with sun-related dark spots, post-inflammatory marks, or broader uneven tone are generally good candidates for one or more of these treatments. Good candidates typically:
Skin type, medical history, and current medications are all reviewed during a consultation, since some of these treatments carry additional considerations for certain skin tones or for patients on medications that increase sun sensitivity.
Anne Therese Aesthetic Medicine, with locations in Lewis Center and Gahanna, Ohio, and Cape Coral and Bonita Springs, Florida, offers IPL/BBL photofacial, Fraxel laser, and chemical peels to address hyperpigmentation and uneven skin tone.
During a consultation, a licensed medical professional or licensed esthetician evaluates your skin, discusses your goals, and builds an individualized treatment plan around which of these options (alone or in combination) fits your specific concern.
This overview is educational and doesn't replace an in-person skin evaluation. Your specific treatment plan is determined by your provider during a consultation.

Treatments are designed to fade and improve the appearance of hyperpigmentation, not erase it, and results vary based on the cause, depth, and individual skin. Continued sun protection helps preserve improvement over time.
Timelines vary by treatment and by how the skin responds, since pigment fades gradually as the body clears it rather than disappearing immediately. A provider can outline a general timeline specific to the treatment recommended during your consultation.
Melasma, which is often hormonally triggered, can be more stubborn to treat than sun-related pigmentation and may respond more slowly or require a combination approach. A provider evaluates whether your pigmentation pattern is consistent with melasma during a consultation, since it can call for a different plan than isolated sun damage.
Yes. Patients addressing pigmentation alongside a separate concern, like texture or radiance, sometimes pair these treatments with something like PRX Derm Perfexion, which works on skin quality through a different mechanism. A provider determines whether combining treatments fits your specific plan during a consultation.
