Laser procedures have become a cornerstone of modern aesthetic care, offering targeted, non-surgical options to refresh and repair the skin. By delivering controlled bursts of light energy into specific skin layers, lasers stimulate natural healing processes—most notably collagen production—so damaged or aged tissue is gradually replaced by healthier, firmer skin.

How laser treatments work

A laser device emits concentrated pulses of light that penetrate the epidermis and dermis. The energy is absorbed by water, pigment, or blood in the skin depending on the laser type, producing controlled micro-injury or thermal effects. That deliberate damage prompts an inflammatory and reparative cascade: new collagen and elastin fibers form, and surface irregularities are shed and renewed. Over subsequent weeks to months, patients often notice smoother texture, reduced discoloration, and a more even tone.

What skin concerns lasers can improve

Laser therapy is adaptable and can be used for a wide variety of cosmetic issues, including:

• Fine lines and dynamic or static wrinkles
• Sunspots, age spots, and photodamage
• Acne scars and other scar tissue
• Uneven pigmentation and melasma
• Enlarged pores and rough texture
• Facial redness, rosacea, and visible blood vessels

Different devices and settings are selected to suit the specific problem and the patient’s skin type, so a customized plan often targets two or more concerns in one treatment course.

Types of laser and light-based treatments

There are several categories of systems commonly used in clinics:

• Ablative lasers: These remove or vaporize the outer skin layer to treat deeper wrinkles and severe sun damage. CO2 and Erbium lasers are typical examples and usually require more downtime but deliver dramatic results.
• Non-ablative lasers: These heat deeper layers without disrupting the surface, encouraging collagen remodeling with less recovery time. Nd:YAG and certain fractional non-ablative platforms fall into this group.
• Fractional lasers: Fractional devices treat only microscopic columns of skin, leaving surrounding tissue intact to speed healing. Fractional approaches exist as both ablative and non-ablative options.
• IPL (Intense Pulsed Light): Technically not a laser, IPL emits a broad spectrum of light wavelengths and is effective for pigmentation, redness, and general skin tone improvement.

A consultation with a qualified provider will determine which option best balances efficacy, downtime, and safety for your needs.

What happens during a session

Treatment begins with cleansing and, if needed, topical anesthetic to improve comfort for more intensive procedures. Protective eyewear is supplied, and the practitioner glides the device over the treatment area, delivering pulses that many describe as quick snaps or a warm prickling sensation. Sessions typically last from 15 minutes for small areas to an hour for full-face interventions. Aftercare generally includes soothing ointment, sunscreen use, and avoidance of direct sun exposure while the skin heals.

Typical course and expected outcomes

Some patients notice immediate improvements like brighter tone and reduced redness, but the most significant changes—particularly collagen-driven tightening and textural smoothing—develop gradually over weeks to months. Many treatment plans recommend 3–6 sessions spaced several weeks apart, though a single aggressive procedure (like an ablative CO2 resurfacing) can sometimes achieve results in one treatment with longer recovery. Maintenance sessions may be advised annually or semiannually depending on goals and lifestyle factors like sun exposure.

Fractional laser	3–4	Moderate (3–10 days)	$400–$1,500
Ablative laser (CO2/Erbium)	1–2	Significant (1–3+ weeks)	$1,000–$4,000
IPL (broadband light)	3–6	Minimal (days)	$150–$500

Risks, side effects, and safety

When performed by experienced clinicians, laser treatments are generally safe, but potential side effects include transient redness and swelling, temporary lightening or darkening of the skin (hypo- or hyperpigmentation), and a sunburn-like sensation. Infrequent complications such as infection or scarring can occur, particularly if aftercare instructions aren’t followed. Treated skin is more photosensitive during healing, so strict sun protection is essential.

Choosing a practitioner and preparing for treatment

Select a board-certified dermatologist or licensed aesthetic specialist with experience in the specific laser you’re considering. During consultation, discuss your medical history, medications, skin type, and expectations. Follow pre-treatment guidance—avoiding certain topical products, recent tanning, or blood-thinning medications when advised—to minimize risk and optimize outcomes.

Aftercare and maintaining results

Post-treatment care typically involves gentle cleansing, hydrating and reparative creams, and sunscreen with high SPF. Avoiding irritants and direct sun exposure helps reduce complications and extend results. Long-term maintenance—sun protection, healthy lifestyle habits, and occasional touch-ups—will preserve the skin improvements.
