No, it is not proven. Activated charcoal is used in many skincare products due to its claims to draw out impurities and toxins from the skin. However, there is limited scientific evidence supporting its effectiveness. Research on activated charcoal’s skincare benefits is lacking. Existing studies often have small sample sizes or are inconclusive. Plus, there are no standardized methods for evaluating its skincare effects. This makes it difficult to draw definitive conclusions.
