Short answer: use your LED mask before your skincare, on clean, dry skin. The order is: cleanse, pat dry, LED session, then serum, moisturizer and, in the morning, sunscreen. Products on the skin can get in the way of the light, and tinted sunscreens are specifically designed to block visible light. The one exception: if your mask’s instructions say to apply a particular product first, follow them.
The right order, step by step
- Cleanse. Remove makeup, sunscreen and the day’s oil with your usual cleanser.
- Pat completely dry. Water droplets and damp skin are best avoided under an electronic mask.
- Run your LED session. Eye protection in, eyes closed, and let the timer end it.
- Apply serum. Vitamin C, niacinamide, hyaluronic acid or whatever you use.
- Moisturize.
- Sunscreen (morning only). The American Academy of Dermatology recommends a broad-spectrum SPF 30 or higher.
- Makeup, if you wear it.
At night, retinol and other evening actives go on after the session, in step 4 or 5, following their own instructions.
Why the mask comes first
An LED mask works by shining light onto the skin, so anything sitting on top can get in the way. A widely cited review of light therapy in skin by Avci and colleagues notes that failing to remove makeup and oily debris can interfere with light reaching the skin. It lists poor skin preparation as one reason light therapy may underperform.
Many skincare products leave a film, and some are designed to interact with light:
- Tinted sunscreens often contain iron oxides. The AAD recommends them precisely because they increase protection against visible light. That is the opposite of what you want during a session.
- Mineral sunscreens and makeup contain pigments and particles that reflect or absorb light.
- Heavy creams and oils leave a layer between the LEDs and your skin.
Clean, dry skin means the light reaches your skin as the mask was designed to deliver it.
The exception: masks designed for a pre-treatment product
A few devices are designed to be used with a specific serum or gel applied first. If your mask’s instructions tell you to apply something before the session, follow the device’s guide rather than the general rule. Instructions for your exact mask always come first.
What about actives like retinol and vitamin C?
Apply them after the session, like the rest of your skincare. There is a second reason to keep strong actives off your skin during a session: some make skin more reactive in general, and applying them after keeps things simple.
A separate question is prescription medication. Oral isotretinoin (Accutane), for example, is named by Healthline as a reason to avoid LED treatment. If you use any prescription skin treatment, ask your dermatologist before adding a light device. Our safety checklist has more.
Common mistakes
- Wearing the mask over sunscreen or makeup. Cleanse first, even in the morning.
- Using it on damp skin straight out of the shower. Pat dry and give it a minute.
- Slathering on a sheet mask or oil “to boost it”. Unless your device says to, keep products for afterwards.
- Doubling up sessions. Once a day at most. Our guide to how often to use a red light mask explains why more is not better.
- Skipping the eye protection because you are in a hurry.

Why blue in the morning? Blue light at night suppresses melatonin more powerfully than other colors, according to Harvard Health. Our guide to the best time to use an LED mask explains more.
The Lumina Pro routine
Our instructions for the Rosune Lumina Pro follow exactly this order. Cleanse and dry, and leave vitamin C, niacinamide and retinol for later. Clip in the eye covers, press power, then M to choose your light, and relax for the 10-minute session. Then apply your usual serum and moisturizer. Afterwards, wipe the inside of the mask with a soft, slightly damp cloth.
Lumina Pro is a general-wellness device and is not FDA-cleared. It costs $149 with free US shipping and a 90-day warranty.
Frequently asked questions
Should I use an LED mask before or after serum?
Before. Use the mask on clean, dry skin, then apply serum afterwards, unless your device’s instructions say otherwise.
Can I wear sunscreen under an LED mask?
It is better not to. Sunscreen, especially tinted mineral sunscreen with iron oxides, is designed to block light. Apply it after your session.
Can I use an LED mask after a chemical exfoliant?
Freshly exfoliated skin can be more sensitive. Keep strong exfoliants for a different time from your session, and stop if your skin feels irritated.
Do I need to wash my face after using an LED mask?
No. Go straight on to your serum and moisturizer.
