Acne scars are one of the most common and frustrating skin concerns patients bring to medical spas. Even after breakouts are under control, the marks they leave behind — whether dark spots, redness, or textural changes — can linger for months or years without targeted treatment.
Photofacials have become an increasingly popular option for addressing post-acne skin concerns, but there's a lot of confusion about what they can and cannot do. Do they work for all types of acne scarring? Are they suitable for every skin type? And what should you realistically expect from a series of treatments?
This guide answers all of those questions with straightforward, clinically grounded information so you can make an informed decision about whether a photofacial is the right next step for your skin.
A photofacial is a non-invasive, light-based skin treatment that uses laser energy to target specific concerns within the skin. At Evolve Med Spa, photofacials are delivered using the Candela GentleMax Pro — a dual-wavelength laser platform with settings precisely calibrated to target chromophores in the skin, including melanin (responsible for dark spots and discoloration) and oxyhemoglobin (responsible for redness and visible vascular changes).
Unlike broad-spectrum IPL devices, the Candela laser delivers focused, single-wavelength energy that allows for greater precision and customization based on each patient's individual skin tone and concerns.
The treatment is non-ablative, meaning it works beneath the skin's surface without removing or disrupting the outer layer. There is no required downtime, and most patients return to their normal activities the same day.
Before determining whether a photofacial is right for your acne scarring, it's important to understand that "acne scars" is a broad term that encompasses several distinct types of skin changes — each with different underlying causes and different optimal treatments.
PIH refers to the flat, darkened marks that remain after an acne lesion heals. These are not true scars in the clinical sense — they are areas of excess melanin production triggered by inflammation. PIH can range from light brown to deep brown or even grayish in tone, and tends to be more pronounced in medium to deep skin tones.
PIE refers to the flat, reddish or pinkish marks left behind after acne heals. These occur due to residual vascular changes — dilated or damaged capillaries near the skin's surface that linger after inflammation resolves. PIE is more commonly seen in lighter skin tones.
Atrophic scars are true structural scars characterized by a loss of tissue, creating depressions in the skin's surface. The three main subtypes are:
These occur when the body produces excess collagen during healing, resulting in raised scar tissue above the skin's surface. They are less common with acne but can occur, particularly on the jawline, chest, and back.
Photofacials are most effective for post-inflammatory hyperpigmentation (PIH) and post-inflammatory erythema (PIE) — the two most common types of residual acne marks.
The laser energy in a photofacial targets melanin deposits in the skin. When PIH is present, the light energy is absorbed by the excess pigment, breaking it down so it can be gradually cleared by the body's lymphatic system. Over a series of treatments, dark marks caused by previous breakouts become progressively lighter and more even in tone.
For red or pink post-acne marks, the photofacial's ability to target oxyhemoglobin makes it particularly well suited. The laser energy is absorbed by the hemoglobin in the residual blood vessels responsible for the redness, causing them to coagulate and be reabsorbed by the body. This gradually reduces the appearance of red marks and evening out overall skin tone.
This is where it's important to set realistic expectations. Photofacials are light-based treatments — they work on pigment and vascular targets, not on structural tissue changes. For true atrophic scarring (ice pick, boxcar, or rolling scars), a photofacial alone is not typically sufficient to produce meaningful textural improvement.
That said, photofacials can improve the overall appearance of skin affected by atrophic scarring by reducing the discoloration and redness that often make these scars appear more prominent. Many patients find that treating the pigmentary component of their scarring makes the remaining textural irregularities significantly less noticeable.
Some evidence supports the use of laser treatments for reducing redness and improving the appearance of hypertrophic scars over time, though results vary. A consultation with your provider is the best way to assess whether a photofacial is appropriate for your specific scar type.
Setting realistic expectations is one of the most important aspects of any aesthetic treatment plan. Here is an honest overview of what photofacial treatments can deliver for acne-scarred skin.
What photofacials do well:
What photofacials cannot do:
Typical results timeline: Most patients notice visible improvement in pigmentation and redness within 1 to 2 weeks of each session as targeted marks rise to the surface and fade. The most significant and cumulative results are typically seen after a series of 3 to 5 treatments spaced 3 to 4 weeks apart.
Skin tone is an important factor in determining candidacy for photofacial treatments, particularly for patients seeking to address pigmentation concerns.
Because photofacials work by targeting melanin, patients with medium to deep skin tones require careful assessment before treatment. In darker complexions, there is a higher concentration of background melanin throughout the skin, which can increase the risk of the laser energy being absorbed by the surrounding skin rather than solely by the targeted pigment — potentially leading to temporary lightening or post-inflammatory hyperpigmentation.
At Evolve Med Spa, our providers conduct a thorough skin assessment prior to treatment to evaluate your Fitzpatrick skin type and determine the safest and most effective treatment parameters. For patients with deeper skin tones, this step is especially critical to achieving results safely.
During treatment: A photofacial session at Evolve Med Spa typically takes between 20 and 30 minutes depending on the treatment area. The Candela GentleMax Pro's built-in Dynamic Cooling Device (DCD) delivers a burst of cooling mist before each laser pulse, making the treatment comfortable for most patients. Some patients describe a mild snapping or warming sensation during treatment.
Immediately after treatment: Mild redness and warmth are common immediately following a session and typically resolve within a few hours. Dark pigmented marks may appear temporarily darker in the days following treatment — this is a normal and expected part of the process, indicating that the targeted pigment is being broken down and brought to the surface before it fades.
In the days that follow: Darkened spots will gradually lighten and fade over 1 to 2 weeks. Patients are advised to avoid direct sun exposure, use a broad-spectrum SPF of 30 or higher daily, and refrain from using exfoliating actives such as retinoids or AHAs in the days immediately following treatment.
The number of sessions needed depends on the severity and type of post-acne marks being treated. As a general guideline:
Your provider will assess your skin at the time of your consultation and recommend a personalized treatment plan based on your specific concerns and goals.
A photofacial is a highly effective treatment for the pigmentary and vascular aftermath of acne — specifically the dark marks and redness that persist long after breakouts have healed. For patients dealing with post-inflammatory hyperpigmentation and erythema, a series of photofacial treatments can produce a meaningful and visible improvement in skin clarity and evenness.
It is not a treatment for structural, textural scarring on its own — but for many patients, addressing the discoloration component of their acne scarring is a transformative first step toward clearer, more even-toned skin.
If you're unsure whether a photofacial is the right treatment for your specific type of acne scarring, the best next step is a consultation with one of our providers at Evolve Med Spa.
