Reviews

Trusted by our customers

Excellent
— Sarah M., 47 | Austin, TX

"I've spent thousands at the dermatologist for ultrasound facials. The Quadthera Titan gives me the same tightening and glow at home — I use it every morning and my skin has never looked better. Three months in and my fine lines are visibly softer"

— Jennifer K., 39 | New York, NY

"I was skeptical — I've tried every at-home device on the market. The Titan is different. You can actually feel the frequencies working. My skin texture improved within the first two weeks. I've recommended it to everyone I know."

— Celine Y., 39 | New York, NY

"What sold me was the 19 MHz frequency — nothing else on the market touches that. My esthetician was genuinely impressed at my last appointment and asked what I'd been doing. The answer was the Titan, every single day"

— Diana R., 44 | Miami, FL

"Clinic appointments were costing me $400 a month. The Titan paid for itself in three visits. I do a 10-minute treatment every night and wake up with skin that looks like I just had a professional facial. It's the best investment I've made in my skincare."

— Michelle T., 52 | Dallas, TX

"My esthetician asked what I'd been doing differently. I told her: the Quadthera Titan, every single day."

— Renee S., 41 | Houston, TX

"Canceled my monthly facial appointments. The Titan does more, at home, for a fraction of the cost."
