KEYWORD-MATCHED SKIN CONCERNS
Shop by Skin Goal
The most searched LED face mask concerns in Canada — matched to the right mask for each goal.
Anti-aging & fine lines
Red light (630–660nm) stimulates collagen and elastin synthesis, visibly reducing fine lines and improving skin firmness over 4–6 weeks.
→ Best pick: Mask 3 (Mode 3) or Mask 5 (Red mode)
Acne & breakouts
Blue light at 415nm destroys P. acnes bacteria at the skin's surface, reducing active breakouts, minimizing scarring, and regulating sebum.
→ Best pick: Mask 3 (Mode 5) or Mask 5 (Blue mode)
Pigmentation & uneven tone
Amber/yellow light (590nm) enhances local microcirculation and supports skin renewal to brighten dull complexions and even out tone.
→ Best pick: Mask 3 (Mode 2 — Pigmentation)
Deep tissue repair & NIR
Near-infrared (830–1072nm) penetrates beneath the skin surface to stimulate fibroblasts, supporting collagen repair at a deeper tissue level.
→ Best pick: Mask 4 (1072nm) or Mask 5 (NIR mode)
Face + neck treatment
Neck skin ages at the same rate as the face — only Masks 2 and 5 treat both simultaneously, eliminating the need for separate devices.
→ Best pick: Mask 5 (wireless) or Mask 2 (wired, more affordable)
Sensitive skin & redness
Red light at low intensity soothes rosacea-prone skin, calms inflammation, and strengthens the skin's moisture barrier without irritation.
→ Best pick: Mask 3 (Mode 1 - Repairing) at 50% brightness
Advanced pulse therapy
Pulsed light therapy at specific frequencies is shown to enhance cellular stimulation beyond what continuous light achieves at the same intensity.
→ Best pick: Mask 5 (0–10,000Hz, most advanced in range)
Health Canada licensed device
Canadian shoppers seeking a device licensed by Health Canada for added regulatory assurance can choose from 3 options in the byTheia lineup.
→ Best pick: Mask 3 ($229), Mask 4 ($329), or Mask 5 ($399)
Decision guide
Which Mask Is Right for You?
Answer these common questions Canadian shoppers ask before buying their first LED face mask.
I've never tried LED therapy before and just want to test it out.
Start with Mask 1. At $39.99 it's the most accessible entry point, fully wireless, and covers the 7 most common LED wavelengths. No learning curve — one button, 10 minutes.
I want face and neck coverage without spending $400.
Mask 2 is your answer. At $129.99 it treats both face and neck with 192 LEDs and sessions up to 90 minutes. It's wired, but significantly more affordable than Mask 5.
I want a Health Canada licensed device with multiple targeted modes.
Mask 3 is the best value Health Canada licensed pick. 6 smart modes, 186 LEDs, 4 wavelengths including NIR 850nm, and a 5000mAh battery — all at $229.99.
I want the deepest possible NIR penetration and a perfect facial fit.
Mask 4's liquid silicone 5D design conforms precisely to your face, and its unique 1072nm NIR wavelength reaches deeper tissue than any other mask in the range.
I want the most advanced, clinically credible device available.
Mask 5 is the clear choice. FDA 510K cleared, 234 LEDs, face and neck coverage, 0–10,000Hz pulse therapy, wireless remote, and the most certifications of any mask in the range.
I have both acne and anti-aging concerns - which mask handles both?
Mask 5's Pink mode (415nm + 630nm) combines anti-acne blue light with collagen-boosting red light in a single mode. Mask 3's Mode 6 (Intensive Regeneration) also addresses both simultaneously.
