STEP 3. PURE TRUTH MELTING CLEANSER: So this is tricky but you are NOT supposed to rinse off the Vitamin C Concentrate. Instead just apply the Melting Cleanser on top of the Vitamin C ( I know it feels kind of weird). Ironically, I didn’t feel any of the tingling or stinging after I applied the cleanser (which it says you will on the package). I left the cleanser on for 10 minutes. BTW, don’t add water to the cleanser, just let it sit on your face. After the time has passed, use the sponge (included) to rinse the vitamin c and cleanser off.
