Aesthetics Terms Glossary

Welcome! You're likely already familiar with the world of aesthetics, and to further assist you, we've compiled an aesthetics glossary.

This glossary aims to clarify and define common terms and buzzwords used in aesthetics and skincare. We cover everything from technical terms to everyday language, starting with 'Aesthetician' and going all the way to 'Wrinkles' (we're still on the lookout for 'Z' words).

Our goal is to make these terms understandable for everyone, whether you're a medical professional or just beginning to explore the aesthetics industry. Here, you'll find the essential vocabulary explained in simple, straightforward language.
