I started using serums only after I bought this one from suhi and sego. I don’t go a single night without it. It quite literally reverses all the damage of the day from the pollution, sun, etc. in one night. Ofcourse it’s merits are many in terms of healing and hydration but let’s talk about how it feels. When I use it, I feel like I’m slathering some sort of elixir on my face or getting skin therapy at some fancy place. Using all the suhi and sego products together truly does feel like the ultimate spa session. Also, I want to highlight how well it pairs with all the other serums I use, be it vitamin C, retinol, etc. it’s the ultimate hydration and healing boost you need (no it didn’t irritate my skin at all)— you can see the difference in <6 months !
