Ablative vs. Non-Ablative Laser Resurfacing: What’s the Difference?

Sun-damaged skin, wrinkles, and acne scars can make your skin look older or more tired than you feel. If you've started looking into laser treatments, you've probably seen the terms "ablative" and "non-ablative" and wondered what they actually mean for you. 

The main difference comes down to depth and recovery. Ablative lasers remove the outer layers of skin, which can lead to more dramatic results but require about 1 – 3 weeks of healing. Non-ablative lasers heat the deeper layers without removing the surface, so recovery is quicker, but results build more gradually over several sessions.

How laser resurfacing renews skin 

Laser resurfacing uses focused light energy to treat damaged skin and trigger your body's natural healing response. As the skin repairs itself, it produces new collagen, which helps the treated area look smoother, firmer, and more even. 

This makes it a versatile option for skin rejuvenation. Many patients use it to soften fine lines and wrinkles, fade discoloration on sun-damaged skin, and improve acne scars, enlarged pores, and uneven texture. Our office offers both ablative and non-ablative options, and the settings can be adjusted to match your skin type and how much correction you want. 

The difference between ablative and non-ablative lasers 

Both types can improve your skin, but they work differently. Here's how ablative and non-ablative lasers compare:  

• How deep they go: Ablative lasers remove thin layers of the skin's surface, while non-ablative lasers pass through the surface to heat the tissue underneath. 
• Best uses: Ablative lasers are often chosen for deeper wrinkles, significant scarring, and heavily sun-damaged skin. Non-ablative lasers tend to work well for early signs of aging, mild discoloration, and fine lines. 
• Downtime: Recovery from an ablative treatment usually takes 1 – 3 weeks, and sometimes longer. Most people return to their routine within a day or two after a non-ablative session. 
• Number of sessions: Ablative results often come from a single treatment, while non-ablative lasers typically require a series of visits. 

Fractional lasers, which treat tiny columns of skin while leaving the surrounding areas intact, come in both ablative and non-ablative forms. Dr. Bodian often combines different lasers to give patients more natural-looking results. 

Understanding treatment and recovery 

On the day of your skin rejuvenation treatment in Great Neck, NY, a numbing cream may be applied to keep you comfortable. Deeper treatments may also include medication or sedation. Most sessions take less than an hour, depending on the size of the area. Results from non-ablative sessions, like softer fine lines and a brighter tone, tend to appear gradually over a few months. 

After a non-ablative treatment, your skin may look red and slightly swollen for a few hours to a few days. After an ablative treatment, expect redness, swelling, and crusting or peeling as new skin forms. In both cases, avoid picking at flaking skin, keep the area moisturized, and wear sunscreen every day.
