Most users should allow at least four weeks of regular use — three to five sessions per week — before expecting noticeable changes. Skin turnover is gradual, and LED therapy works cumulatively rather than acutely.

LED therapy at these wavelengths is generally considered safe across all skin types and tones. Unlike laser or IPL devices, it does not target pigment and carries no risk of thermal damage. If you have a photosensitive condition or take photosensitising medication, check with your doctor before use.

Yes, though it is best applied to cleansed skin without active products on the face during the session. Apply serums or moisturisers after the treatment rather than before, to avoid any occlusion of the light or potential sensitisation.

Red light at 633nm works primarily at the skin surface and is studied for collagen stimulation and improving skin tone and texture. Near-infrared at 830nm penetrates more deeply into the dermis and is associated with cellular repair and reducing inflammation.

Yes — proximity is important in LED therapy. Light intensity follows an inverse-square relationship with distance, so even small gaps reduce efficacy. The flexible silicone construction is specifically designed to minimise this, which is a meaningful practical advantage over rigid mask formats.
