Laser procedures have become a cornerstone of modern skincare, using concentrated light energy to treat a wide range of surface and deeper skin issues. By stimulating collagen production and encouraging cell turnover, lasers can improve texture, reduce pigmentation, and refresh the overall appearance of the skin. Below is a clear guide to what laser skin treatments can do, how they differ, what to expect, and how to make a safe, effective choice.

Which skin concerns can laser therapy treat?

Laser treatments are adaptable and can address many common dermatologic and cosmetic complaints. Typical targets include:

1. Fine lines and wrinkles — reducing creases by promoting collagen and elastin formation.

2. Sun damage and age spots — fading hyperpigmentation and evening skin tone.

3. Acne scars and other scarring — softening textures and improving surface irregularities.

4. Uneven skin tone and rough texture — creating a smoother, more uniform appearance.

5. Enlarged pores — shrinking pore appearance by tightening surrounding tissue.

6. Rosacea and persistent facial redness — calming visible blood vessels and diffuse redness.

7. Unwanted hair — long-term hair reduction when properly targeted.

A qualified clinician will evaluate your skin type, concern, and medical history to determine the most suitable approach.

Types of lasers and light-based options

Not all devices are identical. Choosing the right technology depends on the problem being treated and how aggressive the recovery can be.

• Ablative lasers: These remove the top layers of skin and heat the deeper layers to trigger significant collagen remodeling. They are powerful tools for deep wrinkles, severe sun damage, and substantial scarring, but they typically require more downtime.

• Non-ablative lasers: These heat the dermis beneath the surface without stripping the outer skin, stimulating collagen while preserving the epidermis. They are less invasive, with shorter recovery times, but often need multiple sessions to reach peak results.

• Fractional lasers: Instead of treating the entire area, fractional devices treat microscopic columns of skin, leaving surrounding tissue intact. This speeds healing and can be either ablative or non-ablative, depending on the device and settings.

• IPL (Intense Pulsed Light): Technically not a laser, IPL uses a broad spectrum of light wavelengths to target pigmentation, vascular issues, and uneven tone. It’s versatile but distinct from true lasers in mechanism and effect.

What happens during a treatment session?

Appointments usually start with a thorough cleansing and assessment. For more intensive procedures, a topical anesthetic or cooling device may be used to improve comfort. The clinician moves the handpiece over the targeted area, delivering controlled pulses of light. Sessions can range from a few minutes for small spots to an hour for larger areas.

During treatment you may feel warmth, a snapping or prickling sensation, or mild stinging. Most patients find it tolerable, and practitioners will adjust settings for comfort and safety. Immediately afterward, skin commonly looks pink or flushed and may feel sunburned; swelling is possible. Recovery time varies with the intensity of the procedure and your skin’s response.

Potential risks and side effects

---

Potential Risk/Side Effect	Description	Duration
Redness and swelling	Typical immediate response following treatment	A few hours to several days
Temporary skin darkening or lightening	More likely in darker skin tones or with aggressive settings	Usually resolves within a few weeks
Blistering or scabbing	Possible after more intense resurfacing treatments	Typically heals within 1–2 weeks
Scarring	Rare when treatments are performed by experienced professionals	Can be permanent if it occurs
Infection	Uncommon but may occur without proper aftercare	Varies; requires medical attention

It’s essential to choose a reputable clinic with licensed practitioners to reduce complications. Strictly follow post-procedure instructions—such as sun protection, gentle cleansing, and prescribed topical care—to support healing and optimize results.

How many sessions will you need?

Treatment frequency depends on the condition, device, and your skin. Non-ablative therapies commonly require a series—often 3 to 6 treatments spaced 4–6 weeks apart—to build gradual improvement. Fractional approaches may need fewer sessions than low-energy non-ablative courses. Ablative resurfacing is more intensive and can achieve substantial change in fewer treatments, though downtime and aftercare needs are greater.

Your clinician should create a personalized plan that considers your goals, tolerance for downtime, skin type, and budget.

Choosing the right provider and planning for care

Before committing to treatment, verify the provider’s credentials, ask to see before-and-after photos for similar skin types, and discuss realistic outcomes. Ask about device types, expected recovery, pain management options, and backup plans for complications. Confirm pre- and post-treatment instructions, including sun avoidance, topical regimens, and follow-up visits.

Laser therapy can be a transformative option for many skin concerns when performed safely and thoughtfully. By understanding the types of treatments available, realistic expectations for sessions and recovery, and potential risks, you can make an informed decision about whether laser skin rejuvenation aligns with your goals.
