I had a bad experience with propolis, so I was a bit afraid to order this product, but my previous serum breaks me out, so I had to change quickly, and Iunik was in my wishlist for a long time. The first thing I have to mention is that the beautiful packing, it's so elegant and luxurious, and the vial seems durable (I don't intend to drop it, but we cannot be careful enough :D). The liquid is sticky but in a good way and absorbed quickly. Especially good point that the serum doesn't contain fragrance but it's not smelly. I can't talk about long-time effect, but I don't have any acne and my skin is gorgeous. What else do I need? :D
