So this isn't to do with the product specifically. I actually really love this product. HOWEVER. I have been waiting for a refund since MAY for a bottle of Retinol oil I bought.The bottle had a manufacting issue and the bottom of it came clean off and spilt the oil everywhere on the hotel bed (check image for reference). I have been promised a refund since MAY. I sent in my bank details as asked and yet no refund. No one is getting back to me after numerous emails and at this point I'm clearly just getting ignored. The CS is so poor and embarssing. Do better.
