I use a gentle wax suitable for all types of skin (sensitive or not) on any area of the face (for as long as you do not use any products that do not allow the use of wax). My clients and I find that waxing, tweezing, and cutting are less painful, and faster (apparently time is a commodity in NYC!), than any other method. After your service, I treat the skin with a soothing cream, so you can go on and have a great day!
On the safe side, if you wish to use wax…I recommend that you not use retinol products for two weeks before your eyebrow shaping appointment. However, if you have used these products in the past few days, I can provide you with the ideal shape with tweezing.
