Fractional laser skin resurfacing is a medical-grade cosmetic treatment designed to address a variety of skin concerns, from acne scarring and pigmentation to fine lines and overall skin texture. While this therapy offers noticeable results for many, it’s not suitable for everyone.
In this comprehensive guide, we’ll explore what fractional laser resurfacing is, how it works, who is likely to benefit, and when to consider alternatives, so you can make an informed decision in consultation with a qualified professional.
Common Skin Concerns Treated with Fractional Laser
Fractional laser resurfacing may help improve the following conditions:
- Acne scars
- Surgical or traumatic scars
- Stretch marks
- Fine lines and wrinkles
- Sun damage and age spots
- Uneven skin tone and texture
- Large pores
- Pigmentation irregularities (melasma, post-inflammatory hyperpigmentation)
Treatment outcomes vary based on the condition being treated, the laser used, the number of sessions, and your skin’s healing response.
Am I a Candidate for Fractional Laser Skin Resurfacing?
Fractional laser skin resurfacing can offer visible improvements for a variety of skin concerns, but it’s not suitable for everyone. Understanding whether this treatment aligns with your skin type, medical history, and cosmetic goals is essential before proceeding.
You may be a good candidate for fractional laser resurfacing if:
You have mild to moderate skin concerns
Fractional lasers are commonly used to treat acne scars, fine lines, uneven skin tone, enlarged pores, sun damage, and pigmentation irregularities. They work by creating controlled micro-injuries in the skin, which stimulate collagen production and promote smoother, clearer skin over time.
You are in good overall health
General health plays an important role in how your skin heals post-treatment. Individuals with a healthy immune system are less likely to experience complications or delayed healing.
Your skin is free of active infections or inflammation
Laser treatment is not recommended if you have open wounds, cold sores, or active acne. These should be resolved before undergoing resurfacing to reduce the risk of post-procedure irritation or infection.
You are not prone to keloid or hypertrophic scarring
People with a known history of raised or thickened scars may be advised to avoid laser resurfacing or consider alternative options, as lasers can sometimes trigger abnormal healing responses in susceptible skin.
You have realistic expectations
Fractional lasers provide gradual, cumulative improvements. While many patients notice a visible difference after a few sessions, results vary depending on the condition being treated, skin type, and adherence to aftercare. A clear understanding of what laser resurfacing can (and cannot) achieve is essential for satisfaction.
You are not pregnant or breastfeeding
Although no serious complications have been directly linked to fractional lasers in pregnancy or breastfeeding, most practitioners recommend postponing treatment until after this period as a precaution.
Your skin tone is within a safe treatment range
Modern fractional laser systems can be used on a broader range of skin tones, including darker complexions. However, the risk of hyperpigmentation or hypopigmentation can be higher in Fitzpatrick skin types IV to VI. A qualified provider will evaluate your skin type and customise the laser settings accordingly.
When Treatment May Not Be Suitable
Fractional laser resurfacing may not be appropriate if:
- You’ve recently taken isotretinoin (Roaccutane) within the past 6–12 months
- You have an autoimmune skin condition such as lupus or vitiligo
- You are on medications that cause increased sensitivity to light
- You have very deep wrinkles or significant skin laxity that may respond better to other treatment options, such as surgery or radiofrequency-based therapies
A thorough consultation with a qualified skin doctor or trained laser practitioner is essential before undergoing any laser treatment. Your provider will assess your medical history, skin type, and individual concerns to determine whether fractional resurfacing is the safest and most effective approach for you.
What to Expect: Before, During, and After Fractional Laser Treatment
Fractional laser treatments are designed to improve skin texture, tone, and overall appearance. Understanding what happens before, during, and after treatment can help you feel more confident and informed.
Before the Procedure
Before your treatment, your provider will perform a detailed skin assessment and discuss your medical history to determine if fractional laser therapy is appropriate for you.
You may be advised to:
- Discontinue the use of retinoids, exfoliants, or other active skin products several days prior to treatment
- Avoid certain medications that can affect healing or increase sensitivity to light
- Protect your skin from sun exposure and apply broad-spectrum sunscreen daily
- Ensure your skin is free of infections, cold sores, or active acne
Preparation helps reduce the risk of complications and supports optimal results.
During the Procedure
To minimise discomfort, a topical anaesthetic cream is usually applied before treatment begins.
- You may feel a warm, tingling, or prickling sensation as the laser is applied to the skin
- The procedure typically lasts between 20 and 45 minutes, depending on the treatment area
- Protective eyewear may be provided during the session to shield your eyes from laser light
Most patients tolerate the procedure well, and any discomfort is usually mild and temporary.
After the Procedure
Following treatment, it’s normal to experience temporary skin reactions as part of the healing process.
Common side effects include:
- Redness and swelling, often resembling a sunburn
- Tightness, dryness, or mild irritation
- Peeling or flaking of the skin over several days
Number of Sessions Required
The number of treatments needed depends on your skin condition, treatment goals, and how your skin responds.
- Mild skin concerns may improve with 1 to 2 sessions
- Moderate to more persistent issues often benefit from 3 to 5 sessions, spaced 4 to 6 weeks apart
Your clinician will develop a personalised treatment plan based on your skin type and individual needs.
Are There Any Risks or Side Effects?
While fractional lasers are considered safe when performed by trained professionals, some potential side effects include:
- Redness and swelling (temporary)
- Itching, dryness, or peeling
- Pigment changes (darkening or lightening)
- Infection (rare)
- Scarring (very rare)
Following post-care instructions closely such as using a gentle cleanser, avoiding direct sun, and applying healing ointments is crucial to achieving the best results.
Is fractional laser safe for darker skin tones?
Yes, with newer technologies and experienced providers, treatment can be safe, though there’s a slightly higher risk of pigment changes. Your provider will assess your Fitzpatrick skin type.
Can I get fractional laser if I’ve had fillers or anti-wrinkle injections?
Yes, but it’s best to space treatments appropriately. Most practitioners recommend waiting 2–4 weeks between cosmetic injections and laser.
Can it treat active acne?
No, fractional lasers are not suitable for active acne lesions. However, they can effectively treat acne scars once the acne is under control.
Will one treatment be enough?
Some mild concerns may improve with one session, but most people need a series of treatments for optimal results.
