How to non-ablative lasers work?

Remember – a laser light that penetrates the surface of the skin is ablative while a non-ablative laser does not break the skin’s surface. Non-ablative lasers only heat up the dermis (second layer) beneath the skin to encourage collagen growth. Therefore, these lasers are often used in skin resurfacing to improve firmness and tone. Usually, you will need to undergo more treatments, as non-ablative skin resurfacing is gentler and therefore more gradual.
