The most common reason an LED mask doesn't work isn't the mask itself—it's what's on the skin during the session.
One Rule
Light must reach the skin. Everything else follows from this.
Thick creams, mineral filters with zinc oxide or titanium dioxide, full-coverage makeup—all reflect or scatter light before it reaches the cells.
Before the procedure
| Allowed | Not allowed |
|---|---|
| Cleansing and drying | Creams and oils |
| Toner without active acids | SPF with mineral filters |
| Thin layer of watery serum (optional) | Makeup |
| Nothing—dry, clean skin | Fresh retinoids or AHA/BHA |
The simplest option is the best: clean and dry skin, with nothing on top.
After the procedure
After the session, the skin is at a good moment for active ingredients. Microcirculation is improved and there is no barrier to interfere.
- Hyaluronic acid or peptide serum.
- Moisturizer.
- In the morning – SPF as the last step.
If you use a retinoid, apply it after LED, not before—and wait about 20 minutes.
Irritating combinations
- Fresh retinoid before a session — increases sensitivity and chance of irritation.
- Glycolic or salicylic acid immediately before — same effect.
- Photosensitizing ingredients — some essential oils, e.g., citrus.
- Actives after procedure for rosacea — see separate article.
Sample routine
Evening: cleansing → drying → LED (10–20 min.) → serum → moisturizer.
Morning: cleansing → LED → serum → moisturizer → SPF.
Which time to choose—see morning or evening.
Frequently Asked Questions
Can I use a sheet mask under LED? No. The fabric blocks the light almost completely.
What about conductive gel? Not necessary—that's for ultrasound and RF, not for light.
Do I need to wash my face after a session? No. There's nothing to wash off.
