How to Prep Your Skin Before Red Light Therapy

You booked your first red light therapy session, and you're picturing the glow of the panels and a few quiet minutes to yourself. Here's the part most people skip right past: what you do in the 30 minutes before you sit down quietly decides how much you get out of that time. The good news? Prepping your skin is simple. Once you know the routine, it takes about two minutes.

For folks around East Bethel and the North Metro who are folding red light into a winter wellness routine, a little prep makes each session count, which matters when you're squeezing it in between work, kids, and a Minnesota commute. New to all of it? You can learn more about red light therapy at 5D Wellness and then use this guide to show up ready. Below, we'll cover what "clean skin" really means, a quick pre-session checklist, what to skip, who should check with a provider first, and how to care for your skin afterward.

Why Bare, Clean Skin Matters

Red and near-infrared light does its work at the cellular level. Your cells absorb it, and it's believed to stimulate collagen production and increase blood circulation in the skin. But for any of that to happen, the light has to reach your skin in the first place.

That's where prep comes in. Makeup, sunscreen, lotions, and everyday oily residue all sit on the surface and get in the way. A peer-reviewed review of light therapy in the skin points straight at "lack of removal of makeup and oily debris, which can interfere with the penetration of the light source" as a common prep mistake that makes sessions less effective. Put simply, a full face of makeup isn't just cosmetic during a session. It's a barrier.

Bare, clean skin is the standard starting point, and it's a big reason regulars build a quick cleanse into their visit. Curious about the results side of the equation? Our guide to red light therapy for skin and anti-aging walks through what the light is thought to do over time. For now, the takeaway is simple: clean skin gives the light a clear path.

Your Pre-Session Prep Checklist

You don't need a shelf of products or a complicated routine. You need clean, dry, bare skin and a couple of small habits. Here's what to do before you go, or once you arrive:

  • Cleanse thoroughly. Remove makeup, sunscreen, and oils with a gentle cleanser, then pat your skin dry. Cleveland Clinic's guidance is straightforward: before an in-office or at-home treatment, you want a clean, makeup-free face.
  • Skip heavy products right beforehand. Thick moisturizers, facial oils, and rich serums leave a film on the surface. Save them for after your session unless the studio tells you otherwise.
  • Hold off on self-tanner. A fresh coat of self-tanner or a heavy tinted product changes what's sitting on your skin, so give it a rest around session days.
  • Plan for eye protection. The panels are bright, so goggles or provided shields are part of the routine. Our overview of eye protection and safety basics covers what to expect.
  • Go easy on harsh exfoliation. Scrubbing or a strong acid peel right before a session can leave skin more reactive. Keep the day-of routine gentle.
  • Come comfortable and hydrated. Wear something that gives easy access to the area you're treating, and drink some water beforehand like you would for any wellness session.

Want a simple timeline? The night before, keep your routine gentle and skip the strong exfoliant. The day of, cleanse and go bare. About 15 minutes before your session, your skin should be clean, dry, and product-free, ready for the light.

When to Check With a Provider First

Red light therapy is generally considered gentle and non-invasive, but a few situations are worth a quick conversation with your healthcare provider before you start. This isn't about treating a condition. It's about making sure the therapy is a comfortable fit for you.

Certain medications and conditions increase light sensitivity. Harvard Health notes that people with a light-sensitive condition such as lupus, or who take light-sensitive medications such as certain antibiotics, should be cautious. Cleveland Clinic similarly flags medications that raise sun sensitivity, such as isotretinoin and lithium. If any of that applies to you, check in before booking.

Skin tone matters too. Harvard's dermatologist points out that people with darker skin may be more sensitive to visible red light and suggests starting with lower doses. A good studio will help you ease in either way. And if you're pregnant or managing a medical condition, talk with a qualified provider first, as noted in the disclaimer at the end of this article.

Aftercare and Building a Routine

The nice thing about red light sessions? There's really no downtime, so you can head straight back to your day. That said, a couple of small aftercare habits keep your skin happy.

Right after, if your skin feels a little dry, a gentle moisturizer is welcome, this is the time for it, not before. Cleveland Clinic also suggests being diligent with sunscreen for about 48 hours afterward. Easy to forget in a Minnesota winter, but sun protection is a year-round habit worth keeping.

Most of all, results come from consistency. Harvard's dermatologist describes red light as "slow and steady," the kind of thing that shows up over weeks of regular sessions rather than overnight. Wondering about frequency? Our beginner's guide to how long and how often to book sessions lays out a realistic rhythm. Prep your skin the same simple way each time, and you build a routine that actually sticks.

Frequently Asked Questions

Should I wash my face before red light therapy?

Yes. A clean, makeup-free, oil-free face lets the light reach your skin instead of getting blocked by cosmetics or product residue. Cleanse gently, pat dry, and skip heavy moisturizers or serums right before your session unless the studio directs otherwise.

Can I wear makeup during red light therapy?

It's best not to. Makeup, sunscreen, and oily debris sit on the surface and can interfere with how well the light penetrates, which may make the session less effective. Arrive with a bare face or remove your makeup when you get to the studio.

Do I need to moisturize before or after a red light session?

Go bare before the session so nothing blocks the light. Afterward, a gentle moisturizer can help your skin feel comfortable, and Cleveland Clinic suggests being diligent with sunscreen for about 48 hours afterward since there's no downtime but sun protection still matters.

Is there anyone who should avoid red light therapy?

People taking light-sensitive medications (like certain antibiotics, isotretinoin, or lithium) or living with a light-sensitive condition such as lupus should check with a healthcare provider first. Those with darker skin tones may want to start with lower doses. When in doubt, ask your provider before booking.

The Bottom Line

Good prep is refreshingly simple: show up with clean, bare, dry skin, protect your eyes, skip the heavy products until after, and stay consistent from one session to the next. It's a small habit, but it's the difference between light that reaches your skin and light that stops at your makeup. Build it into your routine and every session works a little harder for you, all year round in the North Metro. Ready to give it a try? Book your session at 5D Wellness in East Bethel.
