Frequently Asked Questions

Using the power of LED technology, this medical-grade device helps target spots, blemishes, lines, and wrinkles over the entire face. It's a wearable, hands-free device using 465nm blue, 633nm red, and 850nm near-infrared wavelengths — delivering clinic-quality results in 10 minutes at home.

Regulatory status varies by exact device, model and market. The US FDA lists the Halo model M-180A under 510(k) K253669 and the Trudermal Pro model ZLD-390 under 510(k) K251012. Ask the seller to confirm the model supplied and provide current documentation for any other device or market.

The Trudermal Glow has 132 LEDs per treatment — engineered for full facial coverage including the upper lip, which many competitor masks omit.

No. Trudermal devices use triple-chip technology, delivering all wavelengths within a given mode simultaneously during each treatment. This maximises the combined therapeutic effect.

The Trudermal Glow has 3 mode settings:

Mode 1 — Anti-Acne: Blue (465nm) + Near-infrared (850nm). Targets bacteria and sebaceous gland activity.

Mode 2 — Acne Repair: Blue (465nm) + Red (633nm). Eliminates bacteria while initiating skin rejuvenation.

Mode 3 — Cell Rejuvenation: Red (633nm) + Near-infrared (850nm). Stimulates collagen and elastin for anti-ageing results.

Anti-Acne mode (Mode 1) is best for pustular, active acne. Acne Repair mode (Mode 2) is better suited for adult or hormonal acne where some skin rejuvenation is also desired.

Cell Rejuvenation mode (Mode 3) uses red and near-infrared light combined to stimulate collagen and elastin production — the key proteins responsible for skin firmness and smoothness.

Cell Rejuvenation mode (Mode 3) is recommended as it aids skin healing by boosting collagen and elastin production while reducing inflammation. Consult your healthcare provider if you have severe or active eczema.

No. Stick with one mode setting for the full 6-week treatment period before switching. This allows your skin to fully respond to a specific wavelength combination rather than receiving mixed signals.

For best results, treat 3–5 times per week for a minimum of 6 weeks. Maintenance treatment should be carried out as required after your initial programme. Consistency is the most important factor — results build cumulatively.

No. Use only 3–5 times weekly. There is no evidence that daily use results in more effective outcomes — the skin needs recovery time between sessions to process the cellular signals and produce new collagen.

You should start to see results from around 4 weeks of consistent use. Taking before-and-after photos every 2–4 weeks helps you track subtle but real changes in skin quality and tone.

Safety depends on the exact device, the user and correct use. Read the supplied instructions and contraindications, use only as directed, and seek professional advice if you use photosensitising medication or have a relevant health condition.

Do not use Trudermal devices if you:

• Are pregnant, planning pregnancy, or breastfeeding
• Have Lupus erythematosus, photosensitive eczema, or Albinism
• Have any photosensitive disorder
• Experience light-induced headaches or epilepsy
• Have a genetic eye condition
• Are taking medications causing photosensitivity (certain antibiotics, chemotherapy drugs, diuretics)
• Are exposed to photosensitising substances (St. John's Wort, coal tar, certain soaps)

If in doubt, consult your healthcare provider before use.

No. Trudermal devices have not been tested on pregnant or breastfeeding women and therefore the risk to the foetus, neonate, or pregnant woman is unknown. Do not use during pregnancy or while breastfeeding.

Prescriptive Retin-A is not recommended for concurrent use. Discontinue Retin-A for 7 days before using Trudermal. For over-the-counter retinol products, check the product label for any light sensitivity warnings before use.

No. Use on clean, bare skin only. Applying serums or creams before treatment creates a barrier that reduces the effectiveness of light penetration. Apply your skincare immediately after treatment instead.

Not recommended during active cancer treatment. Many chemotherapy medications cause photosensitivity. Consult your oncologist or healthcare provider before use.

Yes. The Glow is completely portable and battery-powered. You can move freely, watch TV, read, or go about your routine during the 10-minute session.

The device charges via micro USB and takes approximately 6 hours to fully charge. Each full charge provides approximately 10 treatment sessions. Battery capacity: 3.7v, 2600mAH, 9.62Wh lithium ion polymer.

Approximately 10 treatment sessions per full charge.

Clean the transparent (face-side) of the mask and the rear with a water-based wipe or a damp clean cloth after each use. Store at room temperature in dry conditions. Avoid direct sunlight and high humidity. Do not submerge in water.

First check that the battery is adequately charged and all USB connections are secure. If issues persist within the warranty period, contact us for support. Trudermal devices are covered by a 12-month manufacturer's warranty against manufacturing defects.

Under normal use, Trudermal products are guaranteed for 12 months after the original purchase date against manufacturing defects. This warranty does not cover damage from misuse, accidental damage, or normal wear and tear.
