Lotus III is a fractional multi-pulsed Er:YAG laser developed by Laseroptek, a South Korean medical laser company founded in 2000. It is notably Korea’s first domestically developed fractional multi-pulse 2940nm Er:YAG laser, cleared by the FDA, CE, and Korea’s MFDS. Laseroptek is also the company behind the PicoLO Premium picosecond laser, giving the brand depth across both ablative and non-ablative laser modalities.

How It Works

Er:YAG lasers operate at a 2940nm wavelength, which is highly absorbed by water in the skin. This allows the laser to precisely remove thin layers of damaged skin tissue while generating heat in the deeper dermis to stimulate collagen production. Because Er:YAG energy is absorbed so efficiently by water, it produces less residual heat than CO2 lasers, which generally means a more controlled treatment with a lower risk of thermal side effects.

What distinguishes Lotus III within the Er:YAG category is its range of pulse modes, spanning from USP (Ultra-Short Pulse) at 40 microseconds all the way to ULP (Ultra-Long Pulse). Shorter pulse modes minimize heat spread to surrounding tissue, while longer pulse modes allow for deeper coagulation and more pronounced collagen stimulation. This flexibility lets practitioners tailor the treatment to the specific indication and patient skin type rather than applying a fixed approach.

Lotus III also incorporates Laseroptek’s proprietary DOE (Diffractive Optical Element) fractional technology, the same beam-shaping approach used in the PicoLO Premium. The DOE handpiece distributes energy uniformly across all fractional beams, reducing the risk of uneven ablation or hot spots that can occur with conventional lens arrays.

What It Treats

Lotus III is used for fine lines and wrinkles, uneven skin texture and tone, enlarged pores, acne scarring, and superficial skin growths. Its adjustable pulse modes make it suitable for treatments ranging from lighter brightening and resurfacing sessions to more intensive scar revision protocols.

What to Expect

Recovery varies depending on treatment intensity. Lighter sessions may involve mild redness and flaking for a few days, while deeper treatments can require one to two weeks of healing. Results develop gradually as the skin heals and new collagen forms, and a series of treatments is often recommended for optimal outcomes. Sun protection after treatment is essential.
