How to use
How to use
Step 1 — Position
Wrap the belt around the target area. Secure the velcro strap — firm contact with skin gives the best results. No clothing between the belt and skin.
Step 2 — Select your mode
Use the remote control to choose your light mode and session duration. Start with 20 minutes combined mode (660nm + 850nm) if you're new to red light therapy.
Step 3 — Relax
Stay still during the session. You can sit, lie down, or stand. You may feel a gentle warmth — this is normal.
Step 4 — Repeat daily
Consistency is everything. One session per day, same area. Results build progressively — most users report noticeable improvement between weeks 4 and 8.
Recommended protocol — 8 weeks
Weeks 1–2 · 20 min / day · Combined mode
Weeks 3–8 · 20–30 min / day · Combined or Near-Infrared mode
Important
Do not use on open wounds or broken skin. Keep eyes closed or use protective eyewear during sessions. Not recommended during pregnancy. Consult your physician if you are under medical treatment.

The Problem
Don't Let Loose Skin Overshadow Your Weight Loss Success
You've done the hard work. You're losing the weight, feeling healthier, and taking control of your body. But rapid weight loss, especially with GLP-1 treatments, often leaves behind a frustrating side effect: loose, sagging skin around the midsection.
Your skin needs help to keep up with your shrinking body. SYNELUX uses targeted red light wavelengths clinically proven to stimulate collagen production and restore skin elasticity at the cellular level — before the damage becomes permanent.

I was super skeptical tbh. Lost 45 lbs on Wegovy and my stomach looked like a deflated balloon. I didn't want surgery so I gave this a shot. It took about 4 weeks to really notice it but the crepey skin around my belly button is actually tightening up. It's not a miracle overnight cure but if you use it every day it seriously works.

Had a gastric sleeve 18 months ago. Lost 110 lbs which I'm so proud of but the loose skin around my midsection was really getting to me. I wasn't ready for a second surgery. This belt has genuinely made a visible difference in 8 weeks. The skin is tighter and less wrinkly. Wish someone had told me about this sooner.

I've been on wegovy for 4 months. I started using SYNELUX at month 2 when I noticed the skin loosening. The difference is real. My skin looks like it's keeping pace with my weight loss for the first time.

Week 6 update: The difference is crazy. I wear it while watching Netflix after work, just 20 mins. My stretch marks are fading and the loose skin fold above my c-section scar is lifting. You have to be consistent though, don't buy it if you're only gonna use it once a week.

I'm 8 months postpartum and my belly skin was just not bouncing back. I tried everything. This is the first thing that's actually made a difference. The skin around my belly button is so much firmer. I do it every night after the baby goes to sleep, it's become my little self-care ritual.

Hesitated because of the price but then I looked up how much a tummy tuck costs lol. Best investment I've made for myself. It gave me my confidence back to actually wear a two piece on vacation. Just get it, you have 60 days to return it anyway but you won't want to.

20 Minutes. That's All It Takes.
No gym. No clinic appointments. No recovery time.
Just strap on your SYNELUX belt, press play on Netflix, and let the 660nm red light do the work while you do nothing.
Your skin rebuilds itself. You just have to show up.
TRY IT. IF IT DOESN'T WORK, YOU PAY NOTHING.
What 8 Weeks of Daily Sessions Looks Like.
The results you see here crome from one simple habit: 20 minutes a day, belt on skin, consistently. No creams. No clinic visits. No downtime. As the near-infrared light rebuilds collagen deep in the dermis, the surface gradually firms, tightens, and catches up with the body underneath. The earlier you start, the better — because collagen repair is far easier than collagen recovery.
660nm + 850nm
The two wavelengths that actually do the work.
660nm red light works at the dermal layer — stimulating collagen synthesis, improving skin elasticity, and targeting the laxity that follows rapid fat loss.
850nm near-infrared supports deeper tissue repair and circulation, so results compound over time.
SYNELUX combines both in one device. 100 dual-chip LEDs. CE certified. 20 minutes a day.
Engineered for an 8-week protocol built specifically for post-weight-loss skin changes.
