I’ve used the MAC Studio Finish Concealer ($16.50 USD / $19 CDN) for years! Literally, years. It is the best blemish and acne scar concalaer in the world (choose an NC shade to neutralize redness) because the formula is a little dry so it doesn’t melt off. It lasts all day and its super pigmented so a little goes a long way!
Keep in mind, I’m not a fan of this concealer for under the eyes. It’s way too cakey on me and creases like no tomorrow.
