Great price or excellent product

Beautiful serum
I absolutely adore this serum, it is the most beautiful consistency and feels so light on the skin. I’m not a huge fan of the heavier, sticky serum textures and this is perfectly light but not greasy, and it smells really, really beautiful. I actually look forward to using it! My skin is definitely brighter and more radiant after I’ve used it and I love knowing it is giving me added antioxidant protection, during the day. I will definitely repurchase this as I think the extra price point is totally worth it, my skin feels softer and definitely glows more.

My favourite serum ever!
This is my favourite serum ever. My skin looks so much better when I use it. The texture is more oil than serum, but it absorbs easily.

A good surprise
Did not expect the texture being that liquid and pleasant. Enjoy the feeling on skin once applied. The smell of oranges is really nice and not too concentrated. Looking refreshed and not tired.

Really nice but not what I expected
The texture of this is like a dry oil which I didn’t expect but smells lovely and didn’t cause my any breakouts which is my main concern with any new product
