## Customer Reviews

### ⭐⭐⭐⭐⭐ Does its job!
*by N***B on 29 August 2017*

It's a great serum if you would like to treat hyper-pigmentation, scars, wrinkles, dark circles, acne and fine lines. I have hormonal acne and use this in my skincare regime. It definitely improved my skin by adding a healthy glow and evening out my skin texture. I've only just started dabbing a little bit around my eyes to lighten my dark circles. My only issue is I forget to use it since you have to store it in the fridge.Also I haven't had an issue with oxidisation (and I've had it for 2 months): I always keep it in the fridge inside the original box.

### ⭐ Product leaking! AGAIN
*by E***A on 10 September 2021*

This is the 3rd bottle I order (in a row) the 3rd faulty! the product is all over the box inside and crusty. I cannot believe it, I ordered before and not a problem and now 3 orders that I have to return… are they just selling faulty items? Not sure what is going on..I have also reviewed the previous order… such waste of time…

### ⭐⭐⭐⭐⭐ Clearer Brighter Skin
*by E***Z on 4 October 2016*

I absolutely love this stuff and I think it's helping to fade my hyper pigmentation/scarring from breakouts. It doesn't make your skin lighter which is great because it means you can put it all over the face and not topically but it makes your skin look radiant and super glowy. I've only been using it for two weeks consistently every night but I definitely see a difference in my skin.After you put it on it does feel a little bit tacky, I tend to leave it for 10 - 30 minutes before applying a moisturiser or a sleeping mask and that works for me. I know most people use Vit C in the day o prefer to use it at night, whatever floats your boat really. All in all its a winner for me.
