The MultiFrax Laser in Denver

Treatment pain varries depending on the laser used but at Core Dermatology, we prioritize your comfort. For lighter treatments like HALO, topical numbing cream is sufficient. For deep resurfacing (TRL), Core Dermatology utilizes advanced pain management, including nerve blocks and cooling air, to make the procedure manageable.

MultiFrax can help improve fine lines and wrinkles, acne scars, surgical scars, enlarged pores, and rough or uneven skin texture. It can also reduce brown spots and sun damage, melasma and other hyperpigmentation, and general dullness or loss of radiance.

Most patients choose the face, but MultiFrax can also be used on the neck, chest, hands, and other areas with sun damage, scars, or texture issues, if appropriate for your skin and goals.

MultiFrax is suitable for most skin types and is often used on fair to medium and darker skin tones, and even in patients with melasma.

Your skin is cleansed, and a topical anesthetic cream may be applied for about 30 minutes, although this is often not necessary. The laser handpiece is then passed over the skin in a series of controlled passes; a full-face treatment usually takes about 30–45 minutes, depending on the settings and areas treated.

Most patients describe a feeling of warmth, prickling, or a rubber-band snap sensation during treatment, but topical numbing (if necessary) and cooling measures make it tolerable for the majority of people. Discomfort usually decreases quickly once the treatment is finished.

Right after treatment, the skin typically appears red and slightly swollen, similar to a moderate sunburn, and may feel warm, tight, or rough to the touch. Over the following days, you may notice bronzing, sandpaper-like texture, or tiny dark dots, followed by flaking or peeling as the skin renews.

Most people can resume light, non-sweaty daily activities within 24–48 hours, but visible redness, swelling, and texture changes may last for several days. Depending on treatment intensity, social downtime (when you feel comfortable being seen without makeup) typically ranges from about 2–7 days for the face, with some residual pinkness possible for longer.

Many patients notice improvement after a single session, especially in tone and texture, but optimal results usually require a series. A common plan averages 3 treatments spaced about 2–6 weeks apart, adjusted based on your skin concerns and how aggressively the laser is used. Once an improved skin baseline is achieved, patients often return every 6-12 months for a maintenance, lighter setting treatment.

Some changes in brightness and texture may be visible within days to weeks, as the outer skin renews. Collagen remodeling is gradual, so improvement in firmness, scars, and wrinkles typically builds over 2–5 months and can last months to years with good sun protection, though natural aging and new sun exposure continue over time.

Short-term side effects can include redness, swelling, mild discomfort, bronzing, and flaking, which are expected parts of healing. Less common risks include infection, acne or milia flares, prolonged redness, changes in skin color (darkening or lightening), scarring, or unsatisfactory cosmetic improvement.

MultiFrax is a non-ablative fractional system that can be used in a wide range of skin types, including some darker complexions, but the risk of pigment changes is higher and requires expert, safe parameter selection.

MultiFrax can often be combined with injectables (such as neuromodulators or fillers), light-based treatments (IPL, BBL), laser (VBeam for redness, Morpheus8 microneedling with radiofrequency), or topical skincare to enhance overall rejuvenation when timed appropriately. Your plan will be individualized to determine the safest and most effective sequence and spacing between procedures.

MultiFrax is highly versatile, allowing your provider to replicate settings of Moxi plus any of the other laser device listed above. This means treatments can be customized to your individual goals, and we are not constrained by the more limited settings of other devices.

Similar to Halo, MultiFrax combines two different wavelengths into one fractionated resurfacing device. Halo combines one non-ablative with one ablative laser, while MultiFrax combines two non-ablative lasers. Both are indicated for the same skin conditions, but Halo treatments tend to be more aggressive and with more prominent skin changes during recovery. This is why Halo is often a “one and done” treatment. MultiFrax is perfect for maintaining results after Halo, or for patients that don’t want Halo downtime. MultiFrax is sometimes referred to as “Halo Light”.

A consultation determines the most effective and safe schedule for each person. Dr. Contreras will customize your treatment using settings appropriate for the degree of sun damage and wrinkling present while taking into consideration the allowable recovery time.
