Fractional laser delivers small, pinpoint bursts of light to the skin. This allows more precision and less risk, by keeping patches of untreated skin in between treated areas. Non-ablative fraction laser works by creating microscopic treatment zones of laser energy in your skin dermis to replace damaged skin with healthy, younger looking tissue. The laser energy produces a wound healing response without injuring the skin surface, allowing for a faster recovery time, typically 1-3 days, than ablative lasers.
