A message from Natalie (Founder)
Tweak Cosmetica was created in my Adelaide studio. Working as a lash tech, I saw a gap in the beauty market for a lash growth serum that actually worked. All of my clients were constantly asking for my recommendation. The problem being the oversaturated lash growth serum market delivered products that were not results focused so I didn't feel comfortable recommending. Enter TWEAK.
