I already liked the brand (IUNIK) since trying the propolis serum, but now I'm definitely in love after trying the Tea Tree Relief Serum. I have a sensitive combination skin prone to rosacea. This serum is a great fit for my hyperactive skin! I've just had more problems than usual due to hormonal changes and using this serum while using an excellent centella asiatica lotion on top made all the difference in the redness, bumps and pimples. I totally recommend.
