Can't always follow what's viral...
Olive oil and dimethicone are a bad combination for me. This has such a cult following but my skin reacted immediately after first use. It's been a while since I’ve used it, so I apologize for the ambiguity of this review. I don’t remember the actual way it made me react, whether it was red contact dermatitis or blackheads. I just know it went into my ‘never put on my face’ container.
When products like these don’t work out for me, I typically end up repurposing them. I used this on my décolletage. It didn’t go to waste!
