Ablative Non-fractional Lasers

Compare To Other Treatments

What Is It?

Ablative lasers shine an intense beam of light at the skin. The light completely removes (ablates) the entire epidermis. It also stimulates the underlying dermis to produce more collagen and elastin over time.

Good or Excellent Response

Strength of Evidence
81% of patients achieved a good (>50%) or excellent (>75%) improvement in scarring after 1 - 2 sessions

Moderate Response

Strength of Evidence
97% of patients achieved at least a moderate (>25%) improvement in scarring after 1 - 2 sessions
