I would definitely recommend it.
I loved them. Makes your face look radiant and removes your pimples from your face if you use it daily

Good quality for a decent price point
Excellent set for a reasonable price. Eye serum is not good for those with super sensitive skin (like those prone to eczema), but otherwise works for us!

So far I like it
I bought this combo because I have used the ordinary before and liked the results. So far I’m not a fan of the lotion, feels a bit too thick for my liking. But other 2 products so far are making my skin look brighter and hydrated. I didn’t break out at first with the oil because I’m sensitive to too much oil but my skin adjusted to it. Definitely value for your money.
