Use INIA GLOW 4D after cleansing and drying your face, but before applying leave-on skincare. Complete your GLOW 4D session on clean, dry skin. Then apply serum and moisturizer. If you use the mask in the morning, finish with broad-spectrum sunscreen. In one line: cleanse → dry → GLOW 4D → serum → moisturizer → morning SPF.

Where GLOW 4D Fits in Your Skincare Routine
Think of GLOW 4D as the step between cleansing and leave-on skincare. Products that wash off come first. The light session comes next. Products that remain on your skin go on afterward.
Cleanse and dry
Remove makeup, sunscreen, excess oil, and cleanser residue. Pat the face completely dry before fitting the mask.
Complete one GLOW 4D session
Fit the mask comfortably, select the appropriate mode, and follow the current timing and frequency instructions for your device.
Continue your skincare
Apply serum and moisturizer after removing the mask. Finish a daytime routine with broad-spectrum sunscreen.
Before GLOW 4D: Start With Clean, Dry Skin
Begin by removing makeup and sunscreen, then wash your face with your usual cleanser. Rinse thoroughly and pat the skin dry. Do not apply serum, moisturizer, facial oil, sleeping mask, or sunscreen before putting on GLOW 4D.
This gives you a simple, repeatable starting point and helps keep skincare residue away from the mask's skin-contact surfaces. It also makes it easier to judge how your skin feels during and after the session without another freshly applied product in the routine.
Before every use, check that the mask is clean, dry, charged, and free from visible damage. Align the eye, nose, and mouth openings before tightening the straps. The mask should feel secure without painful pressure around the eyes, temples, cheeks, ears, or jaw.
During GLOW 4D: Keep the Session Simple
Once the mask is positioned comfortably, select the mode that matches your intended routine and follow the current instructions for that mode. Do not extend the session, repeat it immediately, or stack several modes simply because the light feels gentle.
Use the eye setup specified for GLOW 4D and avoid staring directly at illuminated LEDs. If the fit shifts, the straps become painful, or the brightness feels uncomfortable, stop and adjust the mask before continuing.
The session itself is not the time to layer products or perform other facial treatments. Let GLOW 4D be one clear step in the routine. This keeps the process easy to follow and easier to repeat consistently.
After GLOW 4D: Apply Your Leave-On Skincare
After the session, remove the mask and check that your skin feels comfortable. You can then continue with the leave-on part of your routine:
- Serum: apply your usual compatible serum.
- Moisturizer: follow with moisturizer to support hydration and comfort.
- Facial oil: if you use one, apply it according to your normal product order.
- Sunscreen: during the day, finish with broad-spectrum SPF before sun exposure.
Power down and clean the skin-contact side of the mask by the approved method. Let it dry fully before storing it. Keeping aftercare and device care together makes the whole routine easier to remember.

How to Use GLOW 4D in a Morning or Evening Routine
Cleanse → GLOW 4D → serum → moisturizer → SPF
Use the mask before leave-on products. After the session, complete your skincare and always finish with broad-spectrum sunscreen.
Cleanse → GLOW 4D → serum → moisturizer
Place the light session directly after cleansing. Apply the rest of your evening skincare only after removing the mask.
Choose the time of day that makes the routine easiest to maintain. Morning and evening are two placement options—not permission to complete two sessions in one day. Follow the current frequency and mode instructions supplied with your GLOW 4D.
Where Retinol, Vitamin C, and Exfoliating Acids Fit
Retinoids, vitamin C products, exfoliating acids, and other leave-on treatments should not sit underneath GLOW 4D. Complete the light session on clean, dry skin first, then apply the products that belong in that morning or evening routine.
If a retinoid or exfoliating product already leaves your skin dry, irritated, or unusually sensitive, do not force both steps into the same routine. Reduce complexity, separate the products into different routines or days when appropriate, and follow the product directions. For more detail, see how to combine retinol and red light therapy.
A newly introduced active product can make it harder to identify the cause of discomfort. Add one change at a time and pay attention to how your skin responds.
Five Common GLOW 4D Routine Mistakes
- Using the mask over makeup or sunscreen. Cleanse first so the session begins with a fresh, consistent surface.
- Applying serum or moisturizer before the mask. Keep leave-on skincare for after the session.
- Using the mask while the face is still wet. Pat the skin fully dry before fitting GLOW 4D.
- Turning morning and evening routines into two sessions. Follow the approved schedule rather than matching the number of times you wash your face.
- Adding extra time after a missed session. Resume the normal schedule without doubling duration or stacking modes.

When to Pause the Routine
Stop the session if you experience persistent burning, pain, marked redness, eye discomfort, unusual warmth, or another unexpected reaction. Do not use a damaged or wet device, and do not continue when the mask repeatedly shuts down or behaves unexpectedly.
The American Academy of Dermatology advises following the directions for an at-home device. Ask a qualified clinician about personal suitability if you have a light-sensitive condition, take medication that increases light sensitivity, recently had a facial procedure, have a relevant eye concern, are pregnant or nursing, or have another health concern that may affect use.
Your GLOW 4D Pre-Session Checklist
- Makeup and sunscreen are removed.
- The face is clean and completely dry.
- No serum, moisturizer, oil, or active product is under the mask.
- The mask is clean, dry, charged, and undamaged.
- The fit and eye setup feel comfortable.
- You know which mode and session time you are using.
- Your post-session skincare is ready for afterward.
Cleanse First, Use GLOW 4D, Then Apply Skincare
GLOW 4D belongs immediately after cleansing and drying your face. Complete the light session before serum, moisturizer, facial oil, or sunscreen. After removing the mask, continue your normal leave-on skincare and finish a morning routine with broad-spectrum SPF. That is the complete routine: cleanse → dry → GLOW 4D → skincare.
Frequently Asked Questions
Do I use GLOW 4D before or after skincare?
Use GLOW 4D after cleansing and drying your face but before serum, moisturizer, facial oil, and sunscreen.
Should I wash my face before using GLOW 4D?
