Charcoal - Great for getting rid of dead skin. Not having that dead layer on the surface means that your other serums can penetrate a lot deeper as there is nothing blocking them off. It can be used up to 5 consecutive nights in a row - but always ensure you are looking at your skin to see what it needs. 💚 Tingling will vary from not any feeling much to lots of tingling - allow to sit on the skin for 5-10 minutes and wash off 💚 The charcoal was designed to be gentle enough to be used consecutive nights. Rather than applying something that is very acidic and burning the surface of the skin, we found that having an exfoliant that is kind to the skin and gradually exfoliates is much more effective when trying to treat dryness, blackheads and uneven skin tone. It exfoliates just enough without causing trauma to the skin. This one is a wash off product and you will need to look at your skin and what it needs, if you think it needs less or more exfoliation. #atyourskinservice
