The masks
What's the difference between the C16 and the K11?
The C16 is wireless, face-only, six wavelengths, four modes. The K11 is corded, has seven wavelengths (including 520nm green), and comes in face-only or face+neck. Pick C16 for portability; pick K11 for the extra wavelength or neck coverage.
How long is a session?
10 minutes. The session auto-ends.
How often should I use it?
4–5 times a week for everyday use. Daily during the first 4 weeks if you're targeting a specific concern (acne flare, post-procedure recovery).
Can I use it more than once a day?
You don't need to. The published research on the wavelengths Cloakla masks use doesn't show added benefit from longer or more frequent sessions.
Do I apply serums during the session?
No. Light needs to reach skin, not be absorbed by product. Apply serums, moisturizers, and SPF after the session.
Will it hurt my eyes?
The mask includes opaque eye shields that sit over closed eyes. The mask is designed to be used with eyes closed throughout. Do not stare directly into the LEDs without the shields.
Skin & safety
Is LED light therapy safe for sensitive skin or rosacea?
LED light at the wavelengths Cloakla uses is generally well tolerated. The Calm mode (near-infrared, 830/850nm) is the one most associated with redness-prone skin in published research. Start with shorter sessions (5 minutes) for the first week if you're sensitive. If you're under dermatologist care for a specific condition, ask them first.
Pregnant or breastfeeding?
There is no published evidence of harm from cosmetic LED light therapy during pregnancy. We recommend asking your OB/GYN before starting any new device.
Children?
Cloakla masks are designed for adult skin. We don't have research to support pediatric use.
How quickly will I see results?
Most users report a glow or smoothing in 2–3 weeks of consistent use (4 sessions per week). Concerns like uneven tone, fine lines, or texture respond on a longer timeline — give it a full 8 weeks before you judge.
Wavelengths & modes
What does each wavelength do?
- 415nm blue — most studied for acne-associated bacteria (Clear mode)
- 520nm green — surface pigment, tone evenness (Recover mode; K11 only)
- 590nm amber — uneven tone, surface texture (Recover mode)
- 633nm / 660nm red — skin renewal (Glow mode)
- 830nm / 850nm near-infrared — soothing, deeper penetration (Calm mode)
