Light is fundamental to life—and increasingly, to skincare. From stimulating collagen production to re-energizing dormant hair follicles, light therapy has become one of the most clinically supported tools in modern dermatology. Here's a breakdown of how it works and which at-home devices are worth considering.
What Is Light Therapy and How Does It Work?
Photobiomodulation Therapy (PBMT)—formerly known as Low-Level Light Therapy—uses wavelengths in the visible and near-infrared spectrum to treat a range of medical and aesthetic conditions. PBMT promotes wound healing, tissue repair, and reduces inflammation, with no reported negative side effects.
When red and near-infrared wavelengths are absorbed by the skin, they trigger a cascade of cellular events that increase tissue repair and healing—making PBMT a versatile tool for both medical and cosmetic applications.
How Is Light Therapy Used in Dermatology?
In a dermatology context, PBMT has demonstrated benefits for wrinkles, acne scars, hypertrophic scars, and burn healing. Clinical trials have also shown positive outcomes for psoriasis, acne, rosacea, and vitiligo. It's used both to prevent UV-induced skin damage and to accelerate healing after laser resurfacing or surgery.
Light-emitting diodes (LEDs) are the most common delivery method in dermatology, as they allow for convenient, consistent treatment of large surface areas.
How Does Light Therapy Work for Skin Rejuvenation?
LED devices used for skin rejuvenation work by stimulating fibroblasts to produce more collagen, increasing microcirculation in the skin, and reducing apoptosis (cell death). The result is firmer, more youthful-looking skin and faster healing. The anti-inflammatory effects of PBMT also make it effective for improving acne and post-acne scarring.
Recommended At-Home Light Therapy for Skin
Our top pick for at-home PBMT is the Omnilux Contour FACE mask. This hands-free, full-face mask features 13 red (633nm) and 100 near-infrared (830nm) LEDs and is designed for 10-minute sessions, three to five times per week.
After a few weeks of consistent use, most people notice improvements in fine lines, pore appearance, and overall skin texture. With continued long-term use, results compound. To maximize your outcomes, pair the mask with a skincare regimen that includes active ingredients like retinol, antioxidants, peptides, growth factors, and hyaluronic acid.
We also carry the full Omnilux lineup for targeted concerns:

The Bottom Line
Light therapy offers a clinically backed, non-invasive path to better skin—with results that build over time. Whether you're targeting fine lines, acne, or uneven texture, there's an Omnilux device designed for your concern.
