Laser treatment for hyperpigmentation works by targeting melanin deposits in the skin to reduce dark spots, sun damage, post-inflammatory discoloration, and uneven tone. The key variable is depth: different laser and light-based approaches reach different skin layers, and that determines which type of pigmentation each one is suited to address.
Choosing the right approach requires matching the treatment to the source of the discoloration. Sun damage, hormonal pigmentation, and post-inflammatory marks from acne or injury each have different origins and respond differently to treatment. Understanding how each approach works makes it easier to set accurate expectations for a course of treatment.
Hyperpigmentation is a broad term for areas of skin that appear darker than the surrounding tissue. Excess melanin production is the underlying mechanism in most cases.
Common causes:
The depth of the pigmentation matters. Whether the pigment sits in the epidermis (the surface layer) or has deposited into the dermis (the deeper layer) determines how readily it responds to treatment and which approach is most appropriate.
Laser and light-based treatments reduce hyperpigmentation by targeting melanin deposits and triggering their breakdown and clearance.
Concentrated light energy is absorbed by melanin, heating and fragmenting the pigment. The body clears the fragmented melanin over the days and weeks following treatment. Ablative approaches go further, removing outer skin layers to accelerate cellular renewal alongside pigment clearance.
The right approach depends on the type, depth, and distribution of the pigmentation being treated. Skin tone is also a factor: certain wavelengths and settings carry a higher risk of triggering post-inflammatory hyperpigmentation in darker Fitzpatrick skin types, so provider assessment and the correct device/protocol match matter before any treatment begins.
Broadband light (BBL) is Sciton's branded platform for intense pulsed light (IPL), a high-intensity broad-spectrum light that targets melanin at the epidermal level. The light is selectively absorbed by pigmented areas, heating and breaking down the concentrated melanin deposit without affecting the surrounding tissue.
BBL and IPL are well-suited for:
After treatment, dark spots typically darken before they clear. The pigment rises to the surface, with peeling typically beginning within the first week and shedding completing by around 7 to 14 days. Most patients need a series of treatments to address accumulated damage.
Non-ablative fractional lasers create microscopic treatment zones in the skin without removing the surface layer. The surrounding intact tissue accelerates healing, while the treated zones stimulate collagen production and accelerate cell turnover.
For hyperpigmentation, fractional non-ablative devices address pigment distributed throughout the skin rather than concentrated in discrete spots. They produce less downtime than ablative resurfacing and suit patients with diffuse uneven tone who want improvement without a full resurfacing recovery.
Clear + Brilliant is a fractional non-ablative laser suited for early pigmentation, uneven tone, and skin quality maintenance.
Erbium lasers resurface the skin by removing the outer cellular layers in a precise, controlled pass. That process triggers the body's healing response: new skin cells form, collagen production increases, and the skin renews from within.
For hyperpigmentation, the resurfacing removes the surface layer where melanin deposits sit, while the collagen stimulus supports more even tone development as new skin emerges. Erbium lasers are particularly effective for:
Recovery involves a peeling phase as the treated skin sheds and new skin emerges underneath.
For patients dealing with both pigmentation and texture concerns, pairing broadband light (to target active melanin) with an Erbium micropeel (to resurface the outer skin and accelerate cellular renewal) can address more of the concern in one course than either modality addresses on its own.
The BBL step targets active pigmentation; the resurfacing step accelerates cellular turnover and improves texture. At Anne Therese Aesthetic Medicine, both BBL and Erbium lasers are available through the Spotless Peel, a dual-action treatment that delivers both modalities in a single appointment.
Recovery generally follows this pattern, though individual results and timing vary by treatment type, skin tone, and the specific pigmentation being addressed. Here is what is happening in the skin at each stage and what that looks like from the outside.
Days 1 to 2. The treated area responds with mild redness, warmth, and tightness. This is the inflammatory phase, a normal part of how the skin initiates repair.
Days 3 to 7. Dark spots typically darken before they clear. The fragmented melanin rises to the surface before shedding, a process that is expected and temporary. The skin begins to peel during this phase.
Days 7 to 14. As the skin sheds, a brighter, more even tone becomes visible underneath. This is when most patients notice the first clear signs of improvement.
Weeks 2 to 4. Collagen remodeling continues in the deeper layers. Improvement in tone and texture carries on beyond what was immediately visible at the surface.
Weeks 4 to 6. The skin stabilizes between sessions. For a full course of treatment, this is the window before the next appointment.
Most patients notice some visible change after a single session, though individual results vary. A series produces cumulative improvement, particularly for persistent pigmentation such as melasma or accumulated sun damage.
The number of sessions depends on the type and depth of pigmentation, skin tone, and the specific treatment used.
General ranges:
Between sessions, sun protection is required. UV exposure during a treatment course undermines results and stimulates new pigmentation in treated areas.
The Spotless Peel is a dual-action treatment that combines BBL with an Erbium laser micropeel in a single appointment. The BBL step targets active melanin deposits and sun damage; the Erbium micropeel resurfaces the outer skin and accelerates cellular renewal.
This combination approach addresses both pigmentation and texture in one treatment course rather than requiring separate modalities. Because it treats two concerns at once rather than pigmentation alone, the standard course runs slightly longer than a single-modality pigmentation treatment: 3 to 4 sessions, each approximately 60 to 90 minutes, spaced 4 to 6 weeks apart.
A consultation at Anne Therese Aesthetic Medicine identifies which approach fits your skin. The source of your pigmentation, your skin tone, and your timeline all shape which treatment is appropriate and how many sessions are realistic.
Spotless Peel treatments are performed by licensed medical professionals. Dr. Anne Therese Stubbs, MD, Founder and Medical Director, oversees all treatment protocols at the practice.
Anne Therese Aesthetic Medicine has locations in Lewis Center and Gahanna, Ohio, and Cape Coral and Bonita Springs, Florida.

Laser and light-based treatments for pigmentation vary in suitability across skin tones. Darker Fitzpatrick skin types require careful provider assessment and treatment selection before proceeding. Some wavelengths and device settings carry a higher risk of post-inflammatory hyperpigmentation in deeper skin tones when protocols are not matched appropriately.
Results last longer with consistent sun protection after treatment. UV exposure is the primary driver of new melanin production. Without SPF, improvements fade faster and new pigmentation forms. Most patients maintain results through ongoing sun protection and periodic maintenance sessions, particularly for conditions like melasma or sun spots that are chronic rather than discrete.
Post-inflammatory hyperpigmentation is a possible side effect in some skin tones when treatment parameters are not calibrated to the patient's skin. Provider selection and pre-treatment assessment matter for this reason. At Anne Therese Aesthetic Medicine, a consultation reviews your skin tone and history before any treatment is scheduled, and protocols are adjusted to your baseline.
Yes. The Spotless Peel at Anne Therese Aesthetic Medicine combines BBL (a broadband light treatment) with an Erbium laser micropeel. The mechanism differs from a chemical peel: instead of applying an acid solution to resurface the skin, the treatment delivers light energy to target pigmentation and laser energy to resurface the outer skin layers. The result addresses both active pigmentation and skin texture in the same appointment.
