If you need the properties and potential benefits provided by one color, you can buy a one-color mask.
However, keep in mind that all lights have their own properties. Those potential benefits, such as calming effects, anti-inflammatory, anti-aging, stimulation of collagen production, shrinking pores, and soothing redness, can be good for you.
So, since you have decided to buy a mask, we recommend choosing a multicolored one.
