What to Layer With LED Light Therapy: Serums and Products That Help (and What to Skip)

LED light therapy devices are usually used on bare, cleansed skin — but what you put on before and after your session can still make a real difference. Here's a simple layering guide so your skincare and your device work with each other instead of against each other.

Before Your Session: Keep It Simple

Most facial LED devices, including masks and arches like the DermaLux 7-Color LED Therapy Spa, are designed to be used on clean, product-free skin so the light can reach the skin directly rather than through a layer of serum or moisturiser. Cleanse thoroughly and let skin air-dry before starting your session.

Wands and Multi-Function Devices Are the Exception

Devices that combine LED with microcurrent or heat, like the UltraCleanse 6-in-1 or LUMILUX Medicube Age-R Booster Pro, are often designed to be used with a conductive gel or serum, since the added heat and vibration can help improve how well a product moves through the skin's surface. Check your specific device's instructions, since this is one of the bigger differences between device types.

After Your Session: Lock in Hydration

Once your session is done, that's the moment to layer on your regular routine. A hydrating serum followed by a moisturiser is the most commonly recommended follow-up, since skin can be slightly more receptive right after a session and mild post-session dryness is common, especially with infrared-heavy devices.

What to Avoid Right Before or After

• Strong exfoliating acids (AHAs/BHAs) — freshly exfoliated skin is more sensitive, so it's generally better to space these out from your LED sessions rather than stacking them the same day
• Retinoids — similarly, retinol and other retinoids can increase skin sensitivity, so many people use LED sessions on non-retinol nights or in the morning if they use retinol at night
• Photosensitizing ingredients or medications — if you're using a product or medication with a photosensitivity warning, check with a dermatologist before combining it with light-based devices. See our LED light therapy safety guide for more on this

What Pairs Well

Hydrating, barrier-supporting ingredients — think hyaluronic acid, ceramides, and gentle antioxidants like vitamin C in stable formulations — are generally considered safe, complementary choices to use after a session rather than actives that are more likely to cause sensitivity.

Can I use LED light therapy with my regular moisturiser already on?

For most single-purpose LED masks and arches, it's better to wait until after your session. For multi-function wands designed around gel or serum use, follow the specific product's instructions instead.

Do I need special LED-safe skincare products?

No — there's no special "LED-only" product category. The guidance above is really just about timing and sensitivity, not needing to buy anything new.
