This has turned my face into red. It was definitely a burn, as it did not go away for few days. Had to stop on day 3.

I've been using this for 3 weeks and I see the positive dynamics: my skin has already become more elastic, the post-acne gradually lightens. The first 7 days I had this "a very strong tingling but non-irritating sensation" (it's been said on the official The Ordinary site). I would recommend this product.

The product may contain good ingredients bur overall is quite bad. It leaves greasy feeling and look on the skin, more then other Vitamin C products I have used, so I do not recommend it for oily skin. It did not absorb very well and it clogged my pores. I was a shining mess before I decided to stop using it. Also it stings on the skin and it is quite aggressive. There are no soothing ingredients in it in my opinion. Combined with other skin care products once caused unbearable stinging reaction and irritation, which lead me to washing all products from my face and apply soothing cream.

I have noticed a slight change in my skin since I have begun using this, my overall complexion seems smoother however EVERY morning I have woken up stinking of fake tan and now my palms have turned orange! It does apply nicely and instantly smooths my face however it is definitely too harsh and not thick enough to use on it's own so I use a moisturiser and an oil on top.

I really wanted to like this, alas it's impossible. I used this for two weeks; from day one it was very uncomfortable to wear as it really stings. And that's saying something coming from me, an experienced hydroxy acid user. My skin is not sensitive or allergy-prone but I have progressively developed an intolerance to this, with rough patches on parts of my face where the skin is thinner. Not recommended at all. I'm very sorry to say I have nothing good to say about this product.
