IR LL Laser Therapy

Low-level laser (light) therapy (LLLT) is a fast-growing technology used to treat a multitude of conditions that require stimulation of healing, relief of pain and inflammation, and restoration of function. The photons are absorbed by mitochondrial chromophores in skin cells. Consequently, electron transport, adenosine triphosphate (ATP) nitric oxide release, blood flow, reactive oxygen species increase and diverse signaling pathways get activated. Stem cells can be activated allowing increased

tissue repair and healing. In dermatology, LLLT has beneficial effects on wrinkles, acne scars, hypertrophic scars, and healing of burns. LLLT can reduce UV damage both as a treatment and as a prophylaxis. In pigmentary disorders such as vitiligo, LLLT can increase pigmentation by stimulating melanocyte proliferation and reduce depigmentation by inhibiting autoimmunity. Inflammatory diseases such as psoriasis and acne can also benefit.

Ablative laser

This is a wounding laser, which removes thin layers of skin. Types of ablative treatments include the carbon dioxide (CO2) laser and the erbium laser.

Nonablative laser

This is a non-wounding laser, which stimulates collagen growth and tightens underlying skin. This includes many types of lasers as well as intense pulsed light (IPL) devices.

Another type of laser resurfacing, fractional photothermolysis (Fraxel), is available in ablative and non-ablative forms. Although non-ablative laser resurfacing is less invasive and requires less recovery time, it’s less effective than is ablative laser resurfacing.
