These three products looks so promising! The Niacinamide and HA sounds sooo good, and I really love these new packaging too 🥰✨

[@carolynjanegombek6498]

Could you share which one should be use first if using these three serums?

[@MeatGoblin88]

So for mixing niacinamide could I just put a few drops on my hands along with cosrx snail mucin essence?

[@KyraVillanueva-i9t]

Can we use all the three serums at the same time?

[@ndeyefatoudiouf1727]

[@annelegaspi3961]

[@marshahshah]

Just bought the vitamin c. Is it per drop per cheek and forehead?

[@Emptrix]

Is this product paraben and sulfate free?

[@rj15r.90]

what to use first? cosrx niacinaide serum or snail mucin essence?

[@juvait568]

Hello, I just want to ask if do I really need to discard the vit.c serum after 2 months of opening even if there's still a left over product? Can I still use it untill its empty? since I put it in the fridge..

[@roddyvivar8310]

If it changes to an orange color, it's time to say "thank you and goodbye" to it.

[@muah8261]

How do I store it

[@rophalocera3894]

You never mention what not to mix with other ingredients.

[@yasminh78]

I recently bought this vitamin c and it’s really gooood. But the smell is totally offff (smells like fish oil) 😭

[@COSRXcosmetic]

Hello! The scent comes from the raw ingredient! That is vitamin C itself has a slight metallic scent to it. That's just its raw properties talking and there's nothing wrong with the product itself 😘 PS. Glad to hear you're enjoying it!
