Cos de Baha - Ozu review for Vitamin B5 4% + Hyaluronic Acid Serum

My first impression - It has a viscous consistency, bottle is quite lightweight, my first product for this brand How it feels? - For my oily combination skin, it feels quite heavy if I compared to my other hyaluronic acid serum (e.g. Torriden's serum). Slow absorption which requires up to 10 minutes or more to fully absorbed. So, I have to stop and wait before applying other products in my routine. Aside from that, I do think it is effective for deep hydration and enhance the healing process which pairs well with retinols. Suitable for? - Dry skin type, people who reside in dry and cool area
