Acne & Blemish Care
Blue light therapy for acne works at around 460nm, right at the surface of the skin where blemishes form.
Most devices here pair blue with red, so one LED face mask covers congestion and skin texture in the same session.
General wellness devices, not acne treatment, and the difference matters if your skin is more than mildly congested.

Frequently Asked Questions
Blue light at around 460nm is the wavelength associated with blemish prone skin, and that is the reason it appears on these devices. We are not going to claim it clears acne, because these are general wellness devices and that would be a medical claim. What we can tell you is that it works at the surface rather than deeper in tissue, and that people typically use it alongside a simple skincare routine rather than instead of one.
Eight to twelve weeks of consistent use before you draw a conclusion, and photograph your skin at the start in the same light so you have something to compare against. Skin cycles take weeks, so shorter windows tell you very little. If nothing has changed by then, the honest answer is that this is not the right tool for your skin.
Not in the same session. Both leave skin more reactive, and retinoids specifically increase light sensitivity. Use them at a different time of day, and never run a session with product still sitting on the skin. If you are on isotretinoin, speak to your prescriber before using any light device at all.
Both, in practice. Blue works at the surface where blemishes form and red works on texture and tone slightly deeper, so a device running both covers more ground than one running either alone. Almost everything here includes both, which is why colour count beyond that is not worth paying extra for.
On mild congestion, generally yes, on clean dry skin. On skin that is raw, freshly exfoliated, or reacting to a new product, wait until it settles. Anything cystic or painful is a dermatology question rather than a device question, and delaying treatment for something that scars is not a trade worth making.
