How does GFOUK AcanthoClear Therapy Spray Works? The goal of GFOUK Acanthosis Nigricans Therapy Spray is to make the affected skin look better. This can lessen the thickness and darkness of the afflicted skin by exfoliating the skin and promoting cell turnover. Any body parts, even the most intimate and delicate ones, such as the neck, lips, areola, nipple, underarm/armpit, knees, and elbows, can be used. The GFOUK AcanthoClear Therapy Spray contains a combination of natural ingredients that work together to help reduce the appearance of these patches and improve the overall health of the skin. Some of the ingredients in AcanthoGlow Therapy spray may include alpha hydroxy acids (AHAs), which can help to exfoliate the skin and promote cell turnover, as well as antioxidants, which can help to protect the skin from damage caused by free radicals.
