KrXs Salicylic Acid masks are safe for home use and effective enough for the treatment room. 
Salicylic Acid and Licorice Root Extract work to treat acne and the appearance of acne scars. This winning combination is safe for all skin types, making it a staple for the treatment room.
The mask itself is made of ultra-thin Tencel (wood pulp), a highly sustainable material that can be composted in your curbside green bin. Thinner masks enable better skin contact while feeling light as air. Some clients even describe them as feeling like a “second skin.” 
Studies show that thinner masks improve results by providing a better seal, maximizing product delivery.
