COSLUS Prime Day 2025 | 4 Days Only: Unmissable Deals for Your Daily Glow-Up

COSLUS Prime Day is Just Around The Corner. From July 8 to July 11, We're Launching Our Biggest Summer Celebration.

This isn’t just about discounts—it’s an invitation to refresh your daily routine. The soothing pulse of a water flosser, the gentle touch of a facial cleanser, the delicate care of your nails—small rituals that quietly remind you: you deserve attention.

At COSLUS, self-care is a gentle dialogue with yourself. This Prime Day, take that step toward better daily habits. You're worth it.

Enjoy up to 38% off this Prime Day! Whether you need the E40 with stepless speed control for braces and sensitive gums, the C20 Deep Clean for powerful plaque removal, the C30 Customizable Flosser with flexible pressure settings, or the T40 Travel Flosser for on-the-go freshness, all our bestsellers are now on sale.

Bring the spa home with our silicone facial cleansing brushes. Both our bestselling and advanced models are now on sale, with discounts of up to 50% off. It’s the perfect moment to elevate your daily glow routine.

Upgrade your self-care with COSLUS portable nail drills and full manicure kits. This Prime Day, our 2-in-1 Portable Nail Drill with Nail Lamp is available for just $9.9 — bringing salon-quality nail care to your fingertips at an unbeatable price.
