  • Julie. GB

    "I was self-conscious about my stretch marks after delivery. My baby is 6 weeks old and I was feeling down about my body. A nurse friend told me about red light therapy, so I tried this. I can't believe how much my stretch marks have faded! The dark red lines are turning pink and smaller ones are barely visible."★★★★★

  • Emma. D

    "After having twins, I gained so much weight and my belly skin was completely stretched out. I was honestly considering a tummy tuck when my sister recommended this. After 8 weeks of using it daily, I can see my skin tightening and it feels so much firmer. I can wear fitted clothes again without feeling self-conscious!"★★★★★

Description

Finally, a technology that understands what pregnancy has done to your body.

While generic devices only address surface-level concerns, FIRMLY™ uses revolutionary dual-wavelength technology to repair pregnancy-related damage at multiple tissue depths — from stretch mark pigmentation to deep fascial separation.

Complete recovery in one single device

Our advanced system (660 nm + 850 nm) works simultaneously to repair pregnancy-related damage: superficial stretch marks, dermal collagen structure, and deep tissue integrity.

Just 20 minutes a day, while you go about your routine.

Designed for real mom life

No appointments. No interruptions. No need for childcare.

The hands-free belt wraps comfortably around your waist while you fold laundry, watch Netflix, or work from home. A built-in timer guides your session, and the flexible design moves with you.

Professional-grade results at home

Unlike other devices originally designed for pain relief, FIRMLY™ was specifically developed for postpartum skin recovery.

Our dual-wavelength combination delivers professional-level results at an accessible price.

FIRMLY™ 3-Layer Lift Technology

One belt. Three synchronized tissue depths. Complete postpartum recovery.

When you wear FIRMLY™, our exclusive 3-Layer Lift Technology™ activates to repair pregnancy-related damage from the surface down to deep fascial tissues through targeted wavelength therapy.

Layer 1: Surface Restoration Zone (660 nm Red Light)

Penetrates 1–2 mm into the epidermis, where it is absorbed by cellular chromophores.

It specifically targets stretch mark pigmentation, reduces their bright red appearance, and stimulates Type I collagen production by 31% in 4 weeks.

Clinical studies show an 85% improvement in the appearance of stretch marks after 12 weeks.

Layer 2: Collagen Reactivation Zone (Dual-Wavelength Synergy)

Reaches a depth of 3–5 mm into the reticular dermis, where 80% of structural collagen resides.

The synergistic combination of 660 nm and 850 nm wavelengths reactivates dormant collagen production disrupted by pregnancy, increases dermal thickness by 23%, and rebuilds the elastic fiber network for firmer, more supple skin.

Layer 3: Deep Tissue Repair Zone (850 nm Near-Infrared Light)

Penetrates up to 8 mm, reaching the fascia and subcutaneous tissue — where the most persistent postpartum changes occur.

Stimulates fibroblast activity in deep fascia, improves blood flow velocity by 40%, and reduces the persistent “pouch” effect that exercise alone cannot correct.

The Science Behind the Synergy

Our 3-Layer Lift Technology™ is more than just dual wavelengths — it’s precision dosimetry.

Each wavelength delivers optimal therapeutic doses: 660 nm activates surface-level cells, while 850 nm induces deeper structural changes.

The result is layered activation:

  • Visible surface improvements within 2–3 weeks
  • Deeper structural remodeling over 6–12 weeks

For a lasting, full-spectrum transformation.

FAQ

QUESTIONS? WE’VE GOT ANSWERS

Safe to use?

Yes, daily use is completely safe when used according to the instructions.

Clinically Proven Wavelengths

Uses only 660 nm and 850 nm wavelengths, whose safety has been established through decades of research. No harmful UV or blue light.

Advanced Safety Features

A built-in auto shut-off timer prevents overuse. Professional-grade LEDs maintain safe operating temperatures, below body temperature.

Gentle and Non-Invasive

Unlike aggressive treatments, red light therapy is gentle and painless. It does not cause skin damage, irritation, or burns when used as directed.

Important Precautions

Avoid direct eye exposure to the LEDs. Not recommended during pregnancy or for individuals sensitive to light. Consult your doctor if in doubt.

Important: This device is not intended to diagnose, treat, or prevent any disease. Consult your healthcare professional before use if you have medical conditions, are taking photosensitizing medications, or have electronic implants such as pacemakers.

Results – How long does it take?

Most customers notice an improvement in skin texture within the first 2–3 weeks.

Significant skin firming and reduction in the appearance of stretch marks typically become visible between weeks 5 and 8 with regular daily use. Optimal results are achieved after more than 12 weeks of consistent treatment.

What makes FIRMLY™ different from standard red light devices?

FIRMLY™ is the only device specifically designed for postpartum skin recovery, thanks to our exclusive 3-Layer Lift Technology™. Unlike generic devices made for athletes and pain relief, FIRMLY™ targets the three distinct layers of pregnancy-damaged skin with precision dual-wavelength technology (660 nm + 850 nm).

Can I use this product on old stretch marks, or only on new ones ?

FIRMLY™ works on both new and old stretch marks. While newer stretch marks (red/purple) generally respond more quickly, many customers notice significant fading of older silver stretch marks after 8–12 weeks of regular use.

Shipping & Delivery

International Shipping Available

All orders are processed within 24 hours. Fast and reliable delivery to your address.

Delivery Time

Due to extremely high demand, delivery currently takes 5–12 business days, depending on your location.

Order Tracking

You will receive tracking information as soon as your order ships, so you’ll know exactly when to expect it.

How do I know if I’m sensitive to light?

Before your first full treatment, test the device on a small area of your forearm for 3 minutes. If the area becomes red and remains red for more than 2 hours, you may be photosensitive. Discontinue use and consult your doctor if you are taking medications that cause photosensitivity.

Does this work on C-section scars?

Yes, many customers notice an improvement in the appearance and texture of their C-section scar. The 850 nm near-infrared wavelength penetrates deeply enough to promote scar tissue remodeling. However, it is not recommended to apply the device directly over a surgical site until it is fully healed.

Our Guarantee

We offer a 60-day money-back guarantee. If you don’t see any visible improvement in your skin’s texture and firmness, return your device for a full refund. Plus, we provide lifetime customer support to help you maximize your results.

    I’ve added this to my post-shower routine in the evenings. It warms up quickly and feels nice on the skin. I started seeing a firmer look especially on my sides after about 3 weeks of use. Happy with the results so far!

    I didn’t expect much at first, but after several weeks of regular use, the appearance of my skin has improved.

    Nice Product
    I’m post-menopausal and have had saggy skin on my stomach since my late 40s. I’ve been using this during my morning routine while getting ready, and it’s helped with skin firmness way more than the expensive creams I’ve tried.
  • Charlotte D. Jan 2026
    Verified Buyer
    Nice Product
    The change wasn’t immediate, but around the 1-month mark I realized my skin didn’t feel so “loose” anymore. I usually use it after work while watching TV. My husband even commented the other day that I look more toned.
  • Rebecca N. Jan 2026

    Nice Product
    This has become part of my nightly wind-down routine. I pop it on while reading or scrolling before bed. I wasn’t expecting much, but honestly my stomach looks better than it has in years. It’s not a miracle fix, but it’s working.
