What to Put on My Face Before Red Light Therapy
Wondering what to put on my face before red light therapy? Learn why clean skin is best and which serums boost results in this expert guide.
Introduction
Starting an at-home red light therapy routine brings up an immediate question: what should you actually put on your face before turning on your device? Some sources insist on completely bare skin, while others suggest applying hydrating serums or specialized creams first.
At Solawave, we design light therapy tools and compatible skincare to make at-home treatments simple and effective. The truth is straightforward: clean skin is always the safest baseline, but certain lightweight, hydrating formulas can be used beforehand depending on your specific device.
This guide outlines exactly what to apply before a session, which ingredients to save for afterward, and how to build a routine that supports smooth, radiant-looking skin.
Quick Answer: As a general rule, begin with freshly cleansed, dry skin free of makeup, sunscreen, and heavy oils. If you use a device-compatible, water-based product, apply a thin layer and allow it to absorb fully before starting your light therapy session.
Why Your Pre-Light Skincare Layer Matters
Red light therapy delivers targeted wavelengths of light directly to the surface of the skin. For cosmetic at-home devices, red light (around 630nm) and near-infrared light (around 830nm) are commonly used to support a refreshed, firmer, and more uniform appearance.
To deliver those visual benefits, light must reach the skin without physical interference. Anything sitting on top of your skin can alter how light interacts with the surface in several ways:
- Light Reflection: Heavy creams, thick balms, and facial oils leave a shiny film. This glossy surface can reflect incoming light away from your skin.
- Light Absorption: Pigmented makeup, tinted moisturizers, and chemical sunscreen filters are designed to absorb light energy. This prevents the intended wavelengths from reaching the skin evenly.
- Light Scattering: Mineral sunscreens containing zinc oxide or titanium dioxide physically deflect light rays. This scatters the red and near-infrared wavelengths before they reach the surface.
- Uneven Distribution: Dry patches mixed with oily residue create an irregular surface, leading to inconsistent exposure across different areas of the face.
Starting with clean, prepared skin ensures that your session delivers an even, consistent light experience every time.
What to Put on Your Face Before Red Light Therapy
If you want to apply skincare before your session, formulation texture and ingredient selection are essential. You want lightweight, water-based ingredients that hydrate without leaving an occlusive barrier.
1. Water-Based Hyaluronic Acid
Hyaluronic acid is a humectant that attracts and binds water to the surface of the skin. A lightweight, water-based hyaluronic acid serum absorbs quickly and leaves zero greasy residue. Applying a thin layer before light therapy can help prevent the mild surface dryness that some users experience during frequent sessions. Always ensure the serum is fully absorbed and the skin feels dry to the touch before turning on your device.
2. Niacinamide (Vitamin B3)
Niacinamide is a gentle, water-soluble ingredient known for supporting the look of a calm, even skin tone. Because it is non-photosensitizing and typically formulated in light gels or fluids, it is generally safe for pre-session application. It helps support the skin barrier while maintaining a clean, non-reflective surface.
3. Peptides
Peptides are short chains of amino acids that help support the appearance of skin firmness and elasticity. Water-based peptide serums without added heavy oils make excellent pre-treatment options. They absorb easily and prep the skin for a smooth, hydrated look.
4. Dedicated Light-Compatible Formulas
Certain topical formulas are specifically created to pair with light therapy devices. For example, LightBoost Wand Activating Serum is designed to provide glide and optimal skin contact during wand treatments. Similarly, LightBoost Face & Neck Serum and LightBoost Face & Neck Rich Cream are formulated to pair with light therapy masks. When using these topicals, apply them to clean skin and allow them to fully absorb before putting on your device.
| Pre-Session Option | Compatibility | Best For | Key Requirement |
|---|---|---|---|
| Bare, Clean Skin | Universal baseline | All LED devices and masks | Skin must be dry and free of residue |
| LightBoost Wand Activating Serum | 4-in-1 Skincare Wand | Wand sessions | Apply before and during treatment for glide |
| LightBoost Face & Neck Serum | LED face and neck masks | Full-face and chest treatments | Allow to absorb fully before session |
| LightBoost Face & Neck Rich Cream | LED face and neck masks | Full-face and chest treatments | Allow to absorb fully before session |
| LightBoost Eye Cream | LED eye masks | Delicate under-eye area | Tap a pea-sized amount and let absorb fully |
| Hyaluronic Acid Serum | Most LED devices | Dry or dehydrated skin | Water-based only; must absorb completely |
What Skincare Ingredients to Avoid Before Your Session
While hydrating, water-based ingredients work well, several common skincare products should be kept out of your pre-light routine. These ingredients can either block light or increase the risk of skin irritation.
Retinoids and Retinol
Retinol, retinal, and prescription retinoids like tretinoin encourage surface cell turnover. While they are popular for addressing the look of aging, they can make the skin more sensitive to light and heat. Applying retinol immediately before a light therapy session can lead to unwanted redness, dryness, or surface sensitivity. Keep retinoids for your evening routine on alternate days, or apply them after your session if your skin tolerates it well.
Exfoliating Acids (AHAs and BHAs)
Alpha hydroxy acids (such as glycolic and lactic acids) and beta hydroxy acids (such as salicylic acid) lower the skin's surface pH and remove dead surface cells. Using them directly before light therapy may trigger temporary irritation. If your routine includes chemical exfoliants, use them at a different time of day or on days when you are not using your device.
Sunscreens (Mineral and Chemical)
Sunscreen is essential for daily skin protection, but it should never be worn during a red light therapy session. Mineral sunscreens physically bounce light away from the face, while chemical filters absorb light wavelengths. Always wash your face to remove SPF before starting your treatment. You can reapply your sunscreen immediately after morning sessions.
Heavy Oils and Occlusive Creams
Plant oils (such as argan, rosehip, and jojoba) and thick occlusive balms (such as petrolatum or heavy shea butter) create a physical barrier on the skin. This barrier reflects incoming light and can trap heat against the skin during treatment. Save these rich formulas for your final post-session moisturizing step.
Makeup and Tinted Products
Foundations, concealers, and powders contain pigments and minerals (such as iron oxides) that block and scatter light wavelengths. Using an LED mask over makeup leads to uneven light delivery and can trap makeup residue in your pores. Always remove makeup before your LED session to remove all cosmetic products before treatment.
Pro Tip: If your skin feels tight after washing, apply a few drops of a pure, water-based hydrating serum. Wait 60 seconds until your face is completely dry to the touch, then proceed with your light session.
Pre-Session Skincare by Device Type
Different devices have different technical designs and mechanical requirements. How you prep your skin depends on whether you are using a hands-free mask, a spot treatment, or a handheld tool.
+-------------------------------------------------------------------------+
| PRE-SESSION PREP BY DEVICE |
+-------------------------------------------------------------------------+
| 1. Full-Face & Eye Masks: Clean skin -> LightBoost Serum/Cream -> Mask |
| 2. Skincare Wand: Clean skin -> LightBoost Wand Activating Serum -> Wand |
| 3. Blemish Spot Device: Clean, dry, completely bare skin -> Spot device |
+-------------------------------------------------------------------------+
Full-Face LED Masks
The Wrinkle Retreat Pro LED Face Mask is an FDA-cleared device combining four specific wavelengths across 320 LEDs:
- Amber light (605nm) to support a radiant, glowing complexion
- Red light (630nm) to target the appearance of redness and uneven tone
- Deep Red light (660nm) to support the look of aging skin
- Near-Infrared light (830nm) to help skin appear firmer and refreshed
To use the mask, begin with clean skin free of makeup and sunscreen. If you choose to pair it with LightBoost Face & Neck Serum or LightBoost Face & Neck Rich Cream, apply the serum first, follow with the cream, and allow both to fully absorb before putting on the mask. Properly install the supplied protective eyewear, which is required for every session. Secure the straps and run the 3-minute session 3 to 5 times per week.
Handheld 4-in-1 Skincare Wands
The FDA-cleared 4-in-1 Skincare Wand combines red light (630nm) with galvanic current, facial massage, and therapeutic warmth.
Unlike static masks, the Wand requires a smooth surface to glide across the skin without tugging. Apply a generous layer of LightBoost Wand Activating Serum to the first treatment area before turning on the device. Glide the wand in slow upward and outward motions for 3 minutes per area (up to 12 minutes total across four zones), 3 to 5 times per week. Reapply serum as you move to each new section.
Targeted Eye Recovery Masks
The Radiant Renewal Eye Recovery Pro is an FDA-cleared eye mask featuring 80 LEDs across four wavelengths (605nm, 630nm, 660nm, and 830nm).
To prep, apply a pea-sized amount of LightBoost Eye Cream to clean under-eye skin. Tap the cream in gently and let it absorb fully. Make sure the included protective eyewear is installed, position the mask comfortably, and run the 3-minute treatment 3 to 5 times weekly.
Neck and Chest Masks
The Neck & Chest Pro Light Therapy Mask features 320 LEDs powered by 160 dual-core chips, using amber, red, deep red, and near-infrared light.
Start with clean, dry skin on the neck and décolleté. You can apply LightBoost Face & Neck Serum and LightBoost Face & Neck Rich Cream before your session; just allow both formulas to absorb fully before putting on the device. Secure the straps and relax for the 3-minute session 3 to 5 times per week.
Blue and Red Light Spot Treatments
The Bye Acne: 3-Minute Pimple Spot Treatment is an FDA-cleared device combining blue light (415nm) to target the look of blemishes and red light (630nm) to calm the appearance of redness.
For spot treatments, skin prep is different: apply the device to clean, completely dry, bare skin. Do not apply serums, creams, or spot treatments beforehand. Hold the device over the affected area for the 3-minute automatic cycle, once per day per spot.
Building Your Complete Pre- and Post-Light Routine
Structuring your daily routine ensures that your light therapy sessions and active topicals complement each other. You can perform your sessions in the morning or evening based on your personal schedule.
Morning Routine: Refresh and Protect
A morning session can help prep your skin for the day, leaving your complexion looking awake and refreshed.
- Cleanse: Wash your face with a gentle formula like Pre- & Probiotic Hydrating Gel Cleanser. Massage onto damp skin for 30 to 60 seconds, then rinse with lukewarm water and pat dry.
- Mist & Prep: Spray Pre- & Probiotic Refreshing Jelly Mist over the face from 6 to 8 inches away to tone and hydrate.
- Pre-Session Serum (Optional): If using the Wrinkle Retreat Pro LED Face Mask, apply a few drops of LightBoost Face & Neck Serum and let it absorb completely.
- Light Therapy Session: Put on your device (with required protective eyewear installed) and complete the 3-minute treatment.
- Hydrate & Seal: Follow with Pre- & Probiotic Nourishing Moisturizer to lock in hydration.
- Sun Protection: Apply a broad-spectrum sunscreen before heading outdoors.
Evening Routine: Restore and Nourish
An evening routine focuses on thorough cleansing, skin comfort, and barrier replenishment.
- Double Cleanse: Remove all makeup and SPF with an oil cleanser or micellar water, followed by your water-based gel cleanser. Pat skin dry.
- Pre-Light Hydration: If using the 4-in-1 Skincare Wand, apply LightBoost Wand Activating Serum generously to the first zone. If using a face mask, apply your compatible serum and allow it to dry down.
- Light Therapy Session: Complete your 3-minute mask session or 12-minute wand routine.
- Targeted Care: Tap a pea-sized amount of LightBoost Eye Cream around the orbital bone.
- Deep Moisture: Smooth a barrier-supporting cream like LightBoost Face & Neck Rich Cream over your face and neck to nourish the skin overnight.
+-------------------------------------------------------------------------+
| DAILY ROUTINE AT A GLANCE |
+-------------------------------------------------------------------------+
| MORNING: |
| Cleanse -> Mist -> Light Therapy -> Moisturizer -> Daily SPF |
| |
| EVENING: |
| Double Cleanse -> Light Therapy -> Targeted Serums -> Rich Night Cream |
+-------------------------------------------------------------------------+
Practical Safety and Skin Considerations
While at-home red light therapy is non-invasive and gentle, following proper safety protocols protects your skin and eyes:
- Protective Eyewear: Always ensure the supplied protective eyewear is properly installed on the Wrinkle Retreat Pro and Radiant Renewal Eye Recovery Pro before turning them on. Do not rely solely on closing your eyes.
- Light Sensitivity Patch Test: Before your first session, test your skin for light sensitivity. Place the device on your inner forearm for 3 minutes. If the skin turns red and remains irritated for more than two hours, discontinue use.
- Dermatologist Guidance: If you are pregnant, have a medical skin condition, have a history of seizures, or take prescription medications that cause light sensitivity, consult your healthcare provider or dermatologist before starting light therapy.
- Skin Tone Considerations: Users with deeper skin tones (Fitzpatrick types V and VI) can be more sensitive to visible light and warmth. If you are prone to hyperpigmentation, consult a dermatologist to determine the ideal session frequency for your skin.
- Age Requirement: Solawave light therapy devices are intended for cosmetic use by healthy adults aged 18 and older.
Key Takeaway: Consistency matters far more than layering multiple products. Using your device on clean skin 3 to 5 times per week delivers visible, gradual improvements in skin texture and tone over several weeks.

FAQ
Can I put hyaluronic acid on my face before red light therapy?
Yes, you can apply a lightweight, water-based hyaluronic acid serum before your session. Make sure the serum contains no heavy oils and is fully absorbed into the skin before turning on your device. Hydrating the surface beforehand can help prevent feelings of tightness or dryness.
Should I wash my face before using red light therapy?
Yes, washing your face is a necessary first step for every light therapy session. Cleansing removes dirt, makeup, oils, and sunscreen that could otherwise reflect or block light wavelengths. Starting with clean skin ensures that light is distributed evenly across your face.
Can I use vitamin C serum before red light therapy?
It is generally best to apply vitamin C serums after your red light therapy session. L-ascorbic acid and other potent vitamin C derivatives have low pH levels that may cause mild sensitivity when combined with light or warmth. Applying vitamin C after your treatment allows you to enjoy its tone-evening benefits without extra irritation.
What happens if I wear sunscreen during a red light session?
Wearing sunscreen during a session will significantly reduce the effectiveness of your treatment. Sunscreen formulas are specifically engineered to block, absorb, and scatter light rays, which prevents the therapeutic wavelengths from reaching your skin. Always wash off all sunscreen before your session, and reapply it afterward for daytime sun protection.
