Eye Massagers & Under-Eye Care

Not reliably, and it depends entirely on the cause. Dark circles from thin skin showing the blood vessels beneath sometimes look better with improved skin quality over months. Dark circles from bone structure, from pigmentation, or from a shadow cast by the orbital rim will not change, because there is nothing there for a device to act on. Look at your own under eye area in flat lighting first. If the darkness disappears, it is shadow, and no device fixes shadow.

No. Keep your eyes closed for the whole session, every time. These devices sit close to the eye and there is no benefit to exposing the eye itself to the light. If a device is designed to be worn over both eyes, closed eyes are assumed in the design. Anyone with an existing eye condition should speak to an ophthalmologist before using one at all.

A few hours, typically. That immediate result comes from the microcurrent and the massage rather than the light, and it is temporary by nature, which is why people use these before going out. The light component works on a completely different timescale, over months, and you will not feel it. Both are happening, they just do not share a schedule.

A light cream or gel is usually recommended, particularly for microcurrent devices, which need a conductive layer to work properly. Avoid heavy creams and anything oily, since they block light and make the device unpleasant to clean. Do not use it over makeup. Cleanse, apply a thin layer, run the session, then apply your usual products afterwards.

Take them out first. It is a simple precaution and costs you nothing. Lenses can dry out under warmth and there is no reason to leave them in for a ten minute session. If you have had any recent eye procedure, including laser correction, wait until your surgeon says you are clear before adding any device around the eye.
