Moxi is a fractional laser skin treatment designed to improve tone, texture, and pigmentation with minimal downtime. It uses a 1927nm wavelength that targets water in the skin to create tiny columns of controlled damage, triggering the body’s natural healing response. Unlike aggressive ablative lasers that remove entire layers of skin, Moxi leaves most of the skin’s surface intact, which is why recovery takes days rather than weeks.
How the Moxi Laser Works
Moxi delivers laser energy in a fractionated pattern, meaning it treats a grid of microscopic zones rather than the entire skin surface at once. Each of these tiny columns of thermal energy is about one-tenth the size of a hair follicle. The laser targets water in the upper layers of skin, heating it enough to cause controlled damage in precise, evenly spaced columns. The untreated skin between these columns acts as a reservoir for healing, allowing the epidermis to recover quickly while the deeper layers rebuild.
This controlled injury sets off a cascade of repair. The body clears out damaged pigment, generates fresh skin cells, and produces new collagen and elastin in the treated areas. The result is a gradual improvement in skin quality that continues for weeks after each session. Because the 1927nm wavelength penetrates into the superficial dermis, it can reach pigment deposits that sit deeper than what topical treatments typically address, breaking down excess melanin and promoting more even skin tone over time.
What Moxi Treats
Moxi is most commonly used for sun damage, uneven pigmentation, and early signs of aging. It’s particularly effective for brown spots, freckles, and blotchy discoloration caused by UV exposure. Fine lines, enlarged pores, and dull skin texture also respond well to treatment. The term “pre-juvenation” comes up frequently in the context of Moxi because younger patients in their 20s and 30s use it to address early sun damage and maintain skin quality before more significant aging sets in.
For melasma, a stubborn form of hyperpigmentation that often worsens with aggressive laser treatments, Moxi carries a lower risk of triggering a flare compared to ablative lasers. It increases cell turnover, clears excess pigment, and regenerates healthier skin cells. Three to four sessions spaced four to six weeks apart is a typical starting series for melasma, with results lasting roughly 6 to 12 months when combined with sun protection.
What the Treatment Feels Like
A topical numbing cream is applied 30 to 45 minutes before the procedure. The laser portion itself takes just 10 to 15 minutes for a full face. Most people describe the sensation as a warm prickling or light stinging. The short treatment time is one of the reasons Moxi is sometimes called a “lunchtime laser,” though you’ll leave the office with noticeable redness.
Recovery Day by Day
The hallmark of Moxi recovery is something called “mends,” short for microscopic epidermal necrotic debris. These are tiny dark specks that appear on the skin’s surface within the first day or two. They feel slightly sandpaper-like to the touch and look similar to finely ground coffee sprinkled across the skin.
During days one and two, expect redness and the appearance of these mends. The skin may feel warm and tight, similar to a sunburn. By days three through five, the mends begin to slough off naturally as new skin pushes up from below. This is the phase where the skin looks its worst, and it’s important not to pick or scrub. By day seven and beyond, the old debris has cleared and the initial results become visible: smoother texture, reduced pigment, and a more even tone. Most people feel comfortable returning to normal activities and wearing makeup within three to five days.
How Many Sessions You’ll Need
The number of sessions depends on the concern being treated. Mild sun damage and uneven tone typically respond to two or three sessions. Moderate photoaging, established sun spots, melasma, and fine lines generally require three to four sessions. Post-inflammatory hyperpigmentation from acne or injury can take two sessions for recent, superficial marks, or up to four for older, deeper discoloration.
Sessions are spaced four to six weeks apart, and that interval is deliberate. It corresponds to the collagen remodeling cycle, the period during which the body is actively building new structural proteins in response to the previous session’s thermal stimulus. Going sooner doesn’t speed up results and can actually interfere with healing.
Combining Moxi With BBL
One of the most popular treatment pairings is Moxi with BroadBand Light (BBL), a type of intense pulsed light therapy. The two technologies target different layers of pigment. BBL uses a 515nm filter that is absorbed primarily by melanin sitting in the epidermis, the outermost skin layer. Moxi’s fractionated channels penetrate deeper into the superficial dermis, where they can damage pigment-laden cells that BBL can’t reach. A study published in The Journal of Clinical and Aesthetic Dermatology found that combining both treatments reduced sun-induced dark spots significantly more than either treatment alone, even after a single session.
Safety Across Skin Tones
Moxi is considered safe for all skin types, including darker skin tones. This is a meaningful distinction because many laser treatments carry a high risk of post-inflammatory hyperpigmentation in people with more melanin. Moxi’s fractionated, non-ablative approach minimizes that risk, though it isn’t zero. Post-inflammatory hyperpigmentation remains a rare but possible side effect.
People with a history of cold sores should mention it before treatment. The thermal energy from the laser can reactivate the herpes simplex virus in rare cases, so a preventive antiviral may be prescribed beforehand.
Cost per Session
In 2025, a single Moxi session in the United States typically costs between $700 and $900. A full treatment series of three to four sessions runs $2,100 to $3,600 before any package discounts. Pricing varies by geographic area, provider expertise, and whether Moxi is combined with BBL or other treatments in the same appointment. Most practices offer bundled pricing that reduces the per-session cost when you commit to a full series upfront.
