All laser skin resurfacing involves two techniques: Ablative lasers and Non-ablative lasers. Ablative lasers cause the top skin layer to peel off while non-ablative lasers boost collagen production without harming the skin surface. The non-ablative lasers deliver heat deep into the skin through microthermal treatment zones. The heat helps eliminate the old, epidermal pigmented cells and tighten/firm the skin.
For under-eye rejuvenation with lasers, a laser light beam from lasers like CO2 or Q-switched is focussed onto the under-eye area. It is preferred for reducing dark circles, under-eye bags, and under-eye wrinkles. Once the skin heals from the ablative laser treatment, the under-eye skin looks refreshing and less wrinkled. The results last for years. When non-ablative lasers are used, the results are gradual and progressive. They help improve skin texture and pigment.
