Comparing Dermabrasion and Laser Skin Resurfacing
For those seeking to improve age lines, acne scarring, sun damage and other skin concerns, resurfacing treatments offer a proven way to revitalize facial skin and achieve a more youthful, even tone and texture.
Two common approaches are dermabrasion and laser resurfacing. But what exactly is the difference between these two skin rejuvenation techniques? Understanding the pros and cons of each can help you make an informed choice for your specific needs.
Overview of Dermabrasion
Dermabrasion uses a handheld instrument to mechanically "sand" off the upper layers of damaged skin. This allows new skin to regenerate in its place. It has traditionally been performed with a wire brush or rotating wheel covered in a diamond fraise or other abrasive.
The abrasion removes surface irregularities and impaired outer skin to reveal the healthier tissue below. Controlled wounding kickstarts the body's natural healing abilities to create fresher, smoother skin.
Typically performed under local anesthesia, dermabrasion can treat issues like:
Fine lines and wrinkles
Acne scars
Sun spots
Age spots
Some types of superficial skin lesions
Dermabrasion provides excellent results when performed properly. However, it does carry some potential side effects to consider including:
Redness
Swelling
Skin discoloration
Infection
Scarring
How Laser Skin Resurfacing Works
Laser skin resurfacing also removes outer layers of skin to stimulate new collagen growth and skin cell regeneration. But rather than physical abrasion, lasers use targeted beams of light energy directed at the skin.
Pulses of laser light precisely vaporize thin sections of skin tissue without excess burning or injury to surrounding areas. This "laser ablation" takes off damaged surfaces to uncover healthy new skin.
Like dermabrasion, laser resurfacing prompts increased collagen production over the following months as the treatment zone heals. This results in improved elasticity and firmness.
Lasers suitable for skin rejuvenation include:
CO2 lasers
Erbium lasers
Nd:YAG lasers
Pulsed-dye lasers
When performed by an experienced provider, laser resurfacing improves pore size, wrinkles, scars, pigmentation, and overall skin quality. Potential side effects can include:
Temporary redness
Swelling
Blistering
Changes in skin color
Infection
Scarring
Key Differences Between Dermabrasion and Lasers
While dermabrasion and laser treatments both work by removing damaged outer skin, there are several key distinctions between these two resurfacing techniques:
Precision
The laser's focused energy offers more precise control than the manual abrasion of dermabrasion. Lasers can be carefully targeted to treat only very specific areas.
Depth of Resurfacing
Lasers penetrate below the epidermis to various depths depending on settings used. Dermabrasion is limited to more superficial resurfacing.
Healing Time
Lasers usually require 3-21 days of downtime for the treatment zone to heal. Dermabrasion involves longer recovery, typically 10-21 days.
Results
Both improve skin texture, but lasers also tighten skin by stimulating collagen. Dermabrasion does not address loss of elasticity.
Cost
Multi-session laser resurfacing is often more expensive due to equipment costs. Single dermabrasion treatments tend to be relatively affordable.
Technique
Lasers are automated, while dermabrasion relies fully on the provider's skill in controlling the abrasion tool.
Patient Comfort
Topical anesthetics are used for both procedures, but patients sometimes report laser resurfacing as slightly more comfortable.
Ideal Candidates for Dermabrasion
Certain skin conditions respond particularly well to dermabrasion. Ideal candidates for dermabrasion include those with:
Mild to moderate wrinkles
Focused dermabrasion can smooth out fine lines and creases on areas like the mouth, eyes or cheeks.
Superficial acne scars
Scarring limited to the uppermost layers of skin can be diminished through gentle abrasion resurfacing.
Dull, uneven complexion
Dermabrasion retextures the skin surface to improve tone and radiance.
Actinic keratoses
Sanding off precancerous skin growths prevents progression into more serious squamous cell carcinoma.
Some raised scars
Dermabrasion can carefully "sand down" certain elevated, hypertrophic scars.
Best Uses for Laser Skin Resurfacing
Laser skin resurfacing works well for patients seeking to treat:
Deeper wrinkles and creases
Lasers can penetrate below the epidermis to improve more pronounced signs of aging.
Severe acne scarring
Deep laser ablation excises pitted or thick surgical scars from severe acne.
Redness and vascular lesions
Certain lasers target blood vessels to reduce facial redness and spider veins.
Sun spots and pigmentation
Age spots, melasma and other discoloration can be lightened significantly with lasers.
Precancerous growths
Lasers safely eliminate actinic keratoses and precancerous lesions on the face and scalp.
Combining Dermabrasion and Laser for Optimal Results
For some patients, the best results come from combining both dermabrasion and laser skin resurfacing into a dual treatment plan. Benefits of the combined approach include:
Enhanced Wrinkle Reduction
Dermabrasion smooths fine lines, while lasers rebuild collagen for tighter skin.
Better Scar Improvement
Dermabrasion evens out the skin's surface, then lasers remodel scar tissue beneath.
Improved Skin Texture
Removing damaged outer skin with dermabrasion preps for lasers to stimulate smoother new skin growth below.
Shorter Recovery
Gentler dermabrasion means less laser intensity is required, speeding healing.
Reduced Risk of Side Effects
Minimizing laser exposure lowers chances of prolonged redness, scarring or discoloration.
A customized skin rejuvenation plan incorporating both modalities takes advantage of their respective strengths while mitigating limitations of either approach alone.
The Takeaway
While dermabrasion and lasers are both proven techniques for facial rejuvenation, important differences exist between these two modalities. Lasers offer greater precision and collagen renewal abilities, while dermabrasion provides more budget-friendly superficial resurfacing.
Consulting with an experienced cosmetic dermatologist can help identify whether medical dermabrasion, laser skin resurfacing, or a combined approach is best suited for your particular skin concerns and desired outcome.
FAQs
Which is more effective at reducing wrinkles, dermabrasion or lasers?
Lasers typically provide better wrinkle improvement by stimulating new collagen production beneath the skin's surface. Dermabrasion only smooths fine lines on a superficial level.
Does dermabrasion or laser resurfacing have a shorter recovery time?
Laser resurfacing generally requires less downtime, with healing taking 3-21 days versus 10-21 days for dermabrasion procedures.
Which treatment works best for deep acne scars?
The ability of lasers to penetrate beneath the top layer of skin makes them more effective for significantly improving pitted or thick acne scarring.
Is dermabrasion or laser resurfacing less expensive?
Single dermabrasion sessions tend to cost less than a series of laser treatments. The expensive laser equipment and multiple required sessions increase costs.
Can I get both dermabrasion and laser skin resurfacing?
Yes, combining both modalities is a great option for optimal rejuvenation. The two treatments can complement each other for better overall results.
