Let me preface this by saying that $20 does not mean the same thing in Canada as it does in the US. Don't go checking the exchange rate now -- it's just different, even on days where our dollar is actually higher. Realistically, I'd say $25 dollars is more applicable, but I did manage to fit everything on this list under $20 without resorting to minis, DIYs, drug store or value packs -- not that I don't adore all of those things! But in terms of full-sized, regularly available, ready-to-go products, here are ten that fit the price range that I've repurchased.
Indian Aztec Healing Clay $9 -- this is your one-stop solution for all skin problems -- add apple cider vinegar for an extra kick.
Nuxe Reve de Miel Lip Balm $13 -- Pricey for a lip balm, but the best I've tried.
Murad Acne Clearing Treatment $18 -- I use this as an all-over treatment when my skin starts sassing me.
Clinique High Impact Mascara $19.50 -- I don't even know why I bother with anything else. This is hands-down the best mascara I've ever used, and I regret straying from it every single time.
MAC Lipstick $19 -- there's a reason this product is so cult; you get an incredible range of colours, so you're sure to find something you like, and the formulas all come in different finishes with varying levels of hydration.
Inglot Blush $19 -- these are even cheaper if you get just the pan from the Freedom System, but a full-size blush still fits within $20!
OPI Nail Polish $9 -- one of the most famous nail brands in the world for a reason; the formula is unbelievable, the brush is so incredibly easy to maneuver, and you're guaranteed to find a colour that works for you.
Hakuhodo J5523 brush $19 -- it's cheaper, softer and washes up better than the MAC 217. If not for the fact that I had already purchased three when I discovered this, I would have switched over completely.
Pai Muslin Cloth $5 -- screw the Clarisonic, just get 10 of these. Seriously.
Klorane Dry Shampoo $16.99 -- this smells so clean and does such an incredible job that I could go a week without washing my hair (if I were so inclined).
