FAQ | Wellness > Redness or Irritation After Using a Light Therapy Device

WHY THIS CAN HAPPEN

Our light therapy devices do not emit UV light and do not cause sunburn. However, some users may experience redness, warmth, stinging, or a “burning” sensation if their skin is already sensitized.

This reaction is usually caused by over-stimulation of sensitive skin, not a device malfunction.

Common reasons skin may react:

Skin is more likely to feel irritated during or after a session if:

✅ Retinoids or retinol were used recently
✅ AHAs or BHAs (exfoliating acids) were applied before use
✅ Brightening, resurfacing, or exfoliating products were used
✅ Skin is already inflamed, peeling, or compromised
✅ Session intensity or duration was too high for the skin’s current condition

These products and conditions can thin the skin barrier and increase sensitivity to light and heat.

REDNESS, IRRITATION, OR BURNS: WHAT'S THE DIFFERENCE?

Redness, irritation, flushing, or warmth = typically a temporary skin reaction

UV burns = caused by ultraviolet light (not emitted by our devices)

If discomfort occurs, it does not automatically indicate a defect.

What to do if irritation occurs

• Stop using the device and allow skin to fully recover
• Resume only once skin feels calm and normal
• Restart at the lowest intensity and shortest session time
• Use the device on clean, dry skin with no active products applied beforehand

If symptoms persist or worsen, consult a qualified healthcare professional.

How to reduce the risk next time

Before each session:

• Ensure skin is clean and product-free
• Avoid active or exfoliating skincare near treatment time
• Do not use on irritated, broken, or inflamed skin
• Start low and increase gradually as tolerated
