Solyn™ Cyperus Rotundus Skin Serum
Our hair growth inhibitor serum has been clinically tested to deliver real results:
- Slows hair regrowth
- Weakens hair follicles over time
- Lets you go longer between plucking/shaving
- Leaves skin smoother and softer
- Safe for sensitive and dark skin tonesOur Cyperus Rotundus serum stops hair growth at the source by blocking hormones right at the follicle.
The active ingredients block DHT (the hormone that triggers hair growth) directly where you apply it. Less DHT signal = slower, thinner hair growth.
Why this matters:
This works on ALL hair colors—even white and grey hairs that lasers can’t touch. That’s because we’re targeting hormones, not pigment.
It only works where you apply it. No effects on the rest of your body.
What to expect:
Hair growth starts slowing within 1-2 weeks. With continued use, hair comes back finer, sparser, and slower each time.
- We use natural ingredients that work with your skin—not against it.
Cyperus Rotundus Oil is the star player. It’s what slows hair growth by blocking hormones at the follicle.
Olive Oil + Vitamin E moisturize and heal skin after hair removal. No irritation, no razor bumps.
Peppermint Extract cools and soothes as you apply.
Lemon Extract naturally brightens skin and evens out tone.

Why Solyn Works Where Lasers Fail
Facial hair isn’t a surface problem. It’s driven by hormones beneath your skin telling follicles to grow. Most methods just attack the hair. The hormones? Still there.
Here’s why Solyn is different:

Your Journey to Smoother Skin
Week 1: Softer Hair & Skin
Hair regrowth feels noticeably softer and less prickly to the touch. The serum absorbs quickly and skin feels soothed instead of irritated after application
Week 2: Thinner Hair Growth
New hair grows back visibly thinner and lighter. You start spacing out your plucking sessions because there’s simply less stubborn hair to remove.
Month 1: Nearly Invisible Hair
Previously thick, coarse facial hair now grows back fine and barely noticeable. Many areas stay smooth for days or weeks without any maintenance.
Month 3: Confidence Restored
Former problem areas produce only occasional fine hair that’s easily managed. You gain confidence in close-up situations without daily plucking anxiety.
Month 6: Freedom From Daily Removal
Hair follicles have weakened significantly. Most users maintain smooth skin with minimal effort, finally free from the endless daily removal cycle.
