Skin feels fresh, soft, and super hydrated!
I love this set! The rose toner is perfect after cleansing — it tightens my pores without drying me out. The milky toner is my favorite at night — so hydrating and calming, especially with the mushroom + hyaluronic acid. My skin feels soft, smooth, and refreshed all day. Great size for travel too!

moisturizing
I was curious about this product since I saw it very viral on tiktok recommended by an influencer (Nina Pool) so I bought it, since it is small, I said: if I don't like it at least I didn't spend a lot. The truth is my skin is dry and I didn't think it would really work, and I can say that for being the first time that I let myself be carried away by those tiktok recommendations I loved it, mainly the milky toner I use it after washing my face and it leaves it very soft and when I go to put on foundation I combine it and it is incredible. I recommend it 100%
