What 660 nm and 850 nm actually do.

These two wavelengths sit deep in the warm half of the visible spectrum (660 nm) and just past it, into near-infrared (850 nm). They penetrate the upper layers of skin without heating tissue meaningfully. The cosmetic LED literature focuses on these two more than any others.

Independent peer-reviewed work on low-level light at 660 nm and near-infrared has investigated effects on collagen-related markers, fibroblast activity in vitro, and the appearance of skin in clinical photographs. Findings vary by study; effects are typically modest and gradual, observed over multiple weeks of consistent use.

We do not say Albelys is medical. We do not say it treats acne, rosacea, melasma, or wrinkles. We do not invent statistics. What we do have: Albelys is CE marked, and we hold third-party test reports for electrical safety, electromagnetic compatibility and restricted substances. That is the documentation a cosmetic device carries, and we will send you any of it on request. What that is not: a medical device. Those are assessed by a notified body under the EU Medical Device Regulation and registered with Swissmedic before anyone may make a therapeutic claim about them. If you want medical-grade efficacy claims, that is the category to look in, and a dermatologist is the person to ask.

The eye openings are left clear, so you can keep your eyes open during a session — just avoid staring directly into the lit panel. The light is non-ionising and produces no UV. We recommend pausing use during pregnancy or when taking photosensitising medication; consult a healthcare professional in any uncertainty.

If you use the device twice and put it back in the drawer, nothing will happen. The literature describes effects after weeks of consistent, repeated sessions. We designed Albelys for ten minutes, so the threshold to keep going is low.
