LUNA™ 4 overview

Meet LUNA™ 4, the most advanced 2-in-1 deep facial cleansing & firming brush. Its plush, ultra-hygienic soft silicone combines with manually adjustable T-Sonic™ pulsations allowing you to jump modes as you please. Gentle mode offers a soothing cleanse, Deep Mode plunges into deeper skin layers for an in-pore cleanse, while the medium Regular Mode delivers the best of both worlds. Lift away dirt, oil & excess sebum in just 1 minute and follow with sophisticated firming massage routines for fresh, smooth, and younger-looking skin.

LUNA™ 4’s Cleansing Mode channels T-Sonic™ pulsations into the skin, providing a cleanse far superior to handwashing while also enhancing the absorption of your favorite skincare products. In Firming Massage Mode, LUNA™ 4 offers 4 app-guided massage routines and 5 manual massages that use lower-frequency T-Sonic™ pulsations ideal for combating visible signs of aging. These dual benefits make LUNA™ 4 the iconic & essential start of every proper daily cleansing routine.

With staggering customization abilities and brush heads tailored to balanced, sensitive & combination skin, LUNA™ 4 offers a customized professional treatment at home for glowing, flawless results - every time.
