Daily Skincare Routine with LED Therapy: The Step-by-Step Protocol
By Tashiro, Founder of Evaly. Based on clinical trial protocols and four years of personal daily use. Updated May 2026.
TL;DR
- LED therapy works best on clean, dry skin with no products applied. Serums and actives go on after, not before.
- The clinical trial protocol was 4 to 5 sessions per week, 15 to 20 minutes per session. Daily use is fine. Less than 3 sessions per week produces significantly slower results.
- Evening is better than morning for most people because you apply retinol and heavier actives after the session, and you don't need to worry about SPF timing.
- Do not apply retinol before LED. Retinol can be photoactivated by red light, increasing its potency unpredictably and potentially causing irritation.
- SPF is non-negotiable on days you use LED therapy. Stimulating collagen production while skipping sun protection is counterproductive.

Where does LED fit in a skincare routine?
The question people get wrong most often is product sequencing. Most guides say "use LED after cleansing." The more important point is what you should NOT have on your skin when you use it.
Light photons need to reach dermal tissue without being absorbed by surface products. Heavy moisturizers, oils, and serums sitting on the skin surface can partially block or scatter light before it reaches the target layer. Some active ingredients, particularly retinoids and AHA acids, may be chemically activated by red light exposure and behave differently than expected (1).
The working rule: LED on clean, dry, product-free skin. Apply everything after.
Morning vs evening: which is better?
Evening is better for most users, for three practical reasons.
First, your post-LED window is best used for your most active skincare products: retinol, peptide serums, and heavier moisturizers. These are all nighttime products. Doing LED in the evening naturally sequences into the most effective product stack.
Second, LED stimulates cellular energy production in the skin. This cellular activity continues for several hours after the session. Applying sun protection in the morning independently of LED use is correct, but the skin's enhanced metabolic state is better supported by the repair-mode environment of sleep than by daytime UV exposure.
Third, morning routines are typically shorter and more constrained by time. A 15-minute LED session in the morning adds friction to a routine that is already competing with work, transit, and breakfast. Consistency is the most important factor in outcomes, and evenings are generally less contested.
Morning use is not harmful. Some users with night routines that already include multiple steps prefer to separate LED into the morning. The biology does not change based on time of day. The argument for evening is about practical consistency and product sequencing, not photobiology.
The full evening protocol step by step
EVENING LED PROTOCOL
- Double cleanse (oil cleanser + water-based cleanser): Remove SPF, makeup, and daily pollution. Clean skin is the foundation. Oil-based residue affects light transmission.
- Pat dry completely: LED works best on completely dry skin. Damp skin is fine but does not improve outcomes. Wait 2 minutes if needed.
- LED session, 15 to 20 minutes: Full session at your device's standard setting. Lie down or sit still. No products on skin. Safety goggles or keep eyes closed throughout if device instructions require it.
- Apply hyaluronic acid or hydrating toner: LED slightly warms the skin and opens capillaries. A hydrating first layer takes advantage of this state. Hyaluronic acid or centella water toner. Wait 30 seconds.
- Active serum (retinol, peptide, niacinamide): Your primary active goes on now. Retinol applied after LED is safe and effective. Never apply retinol before your LED session.
- Moisturizer or barrier cream: Lock in the serum layer with your standard moisturizer. Ceramide-containing formulas support barrier integrity that LED also improves over time.
- Facial oil (optional): If you use facial oil as the final occlusive step, it goes on last.
Total time added to routine: 15 to 20 minutes for the LED session itself. Product application adds 5 minutes.
Morning use: how to make it work
If you prefer mornings, the sequence changes slightly:
- Cleanse (single gentle cleanser or water rinse if skin is clean from the night before)
- Pat dry
- LED session, 15 to 20 minutes
- Antioxidant serum (Vitamin C, niacinamide): both work well in the morning and complement the cellular activation from LED
- Moisturizer
- SPF 30 or higher (non-negotiable, applied last)
The morning version is simpler. The trade-off is that you lose the synergy with retinol and heavier nighttime actives. If your main concern is sun protection and antioxidant defense, the morning slot works fine.
What not to apply before or during LED
These should not be on your skin during an LED session:
- Retinol or retinoids: Can be photoactivated, increasing potency unexpectedly. Always apply after your session, not before.
- AHA/BHA acids: Glycolic acid, lactic acid, salicylic acid. These increase photosensitivity. Use them after, not before or during.
- SPF products: Chemical sunscreen absorbs UV and visible light and can partially block the wavelengths you are trying to deliver. Mineral SPF (zinc oxide) also has some scattering effect. Apply SPF after LED, in the morning step.
- Heavy oils or silicone-based primers: Surface occlusion. Apply after, not before.
- Photosensitizing medications (topical): Doxycycline, certain antibiotics applied topically, and methotrexate-based treatments increase photosensitivity. Consult your prescribing doctor before starting LED therapy if you are on these.
What is fine to have on skin during LED: plain water, micellar water (if cleanser residue is minimal), and aloe vera gel (no active ingredients).
How many sessions per week do you actually need?
The Wunsch and Matuschka 2014 RCT used twice-weekly 20-minute sessions over 12 weeks and showed significant collagen improvement (2). The Avci 2013 review of photobiomodulation protocols found that 3 to 5 sessions per week produced measurable improvement in 8 to 12 weeks across multiple outcome measures (3).
The honest answer on frequency:
- 5 sessions per week: Optimal. Aligns with anagen cycling support and produces the fastest measurable result.
- 3 to 4 sessions per week: Clinical trial range. Produces measurable improvement at 12 weeks.
- 1 to 2 sessions per week: Produces some benefit but significantly slower. Results at 12 weeks will be modest compared to clinical benchmarks.
- Daily: Safe. The skin does not "saturate" with LED photobiomodulation the way it can with certain actives. Daily use is not excessive.
Consistency over intensity. Five 10-minute sessions produces better outcomes than two 25-minute sessions per week at comparable total dose. Frequency drives the accumulated cellular response more effectively than session length within reasonable ranges.
Which wavelength for which concern?
Table 1. LED wavelength guide for consumer masks. Multi-wavelength devices cover multiple concerns simultaneously.
The Evaly LED Nano Therapy Mask uses 7 wavelengths simultaneously. Most consumer concerns are addressed by the 630nm/830nm combination. The blue and yellow channels add acne and redness benefits in a single session without switching settings.
THE DAILY LED ROUTINE AT A GLANCE
1
Cleanse
Double cleanse to remove SPF, makeup, and daily pollution. Pat dry completely. No product on skin.
2
LED Session
15 to 20 minutes on clean dry skin, 4 to 5 evenings per week. Eyes closed or safety goggles on.
3
Hydrate + Active
Apply hyaluronic acid first, then retinol or peptide serum. The post-LED window is when these work best.
4
Seal
Moisturizer to lock in the treatment layers. Facial oil optional. Morning: always finish with SPF 30+.
KEY TAKEAWAYS
- LED belongs on clean, dry, product-free skin. Everything else layers on after.
- Evening use is better for product sequencing. Morning use works fine if your routine is better structured that way.
- Never apply retinol before your LED session. Always after.
- 3 to 5 sessions per week matches the clinical trial protocols. Frequency beats duration.
- SPF every morning, regardless of when you use your LED mask.
FAQ
Frequently asked questions
Can I use my LED mask every day?
Yes. Daily LED use is safe and does not over-stimulate the skin the way some daily actives can. The photobiomodulation response does not saturate at daily frequency. If you notice any unusual sensitivity, reduce to 5 sessions per week.
Do I need to wear eye protection during LED?
Check your specific device instructions. Most LED masks are designed so that the light does not direct into the eyes at therapeutic intensity. Some include eyehole shields. When in doubt, keep eyes closed. Avoid staring directly at any LED light source.
How long before I see results from daily LED use?
The Wunsch 2014 RCT used 24 sessions (twice weekly for 12 weeks) and showed measurable collagen improvement. At daily use, you accumulate 24 sessions in roughly 5 weeks. Expect first visible results at 8 to 10 weeks of consistent daily use.
Can I use LED during pregnancy?
LED therapy at consumer device intensity has no established mechanism for fetal harm. However, there are no RCTs in pregnant populations. Most dermatologists advise caution due to lack of data rather than known risk. Consult your doctor.
Can I use LED if I have melasma or hyperpigmentation?
Red and near-infrared wavelengths do not trigger melasma and are generally safe. Blue and green wavelengths have mixed evidence for pigmentation. If you have active melasma, confirm your device's wavelength output and consult a dermatologist for the most current guidance.
Should I use LED before or after my face oil?
Before. Face oil applied over skin during LED can scatter light. Apply oil after your session as the final occlusive layer in your routine, not before.
