All Tattoo Goo® products have all been tested in controlled dermatological studies. Each study confirmed that our products caused no irritation or allergic reactions. Lavender oil soothes irritated skin (plus it smells great). Their blend of natural ingredients includes a beeswax base, premium grade olive oil and cocoa butter. Vitamin E provides a protective barrier that aids in faster healing and serves as a moisturiser, which is also great for healed tattoos because moisturised skin = vibrant ink.
