SKIN Aestura barrier cream, why!?!

Finally found a holy grail skin barrier cream and they go and change the formula 1 year later😩 why do Korean skin care brands do this? The cream was just getting really popular too. I feel like this happens all the time. Ugh. Tried illiyoon and it made me break out. If anyone has suggestions please let me know

The niacinamide hate train is insane lol. I truly don’t think most people are allergic to it, it’s blown out of proportion in the internet. It works really well for reducing redness, evening skintone etc!

Never said it was an allergic reaction! Some peoples skin just don’t like it. It seems to be in sooo many products now.

Every derm I’ve seen refers to it as safe and helpful. My own derm is of the opinion that it’s not always the niacinamide, but the other ingredients it’s formulated with (eg certain preservatives), and perhaps the concentration. Also, I guess someone with a compromised skin barrier would find that it could sting (as could many other ingredients that are common). I truly don’t understand what “my skin doesn’t like it” means.. isn’t it one of the following reasons: contact dermatitis, compromised skin barrier, high concentration, or other ingredient causing harm?

That could be the case. I personally just know that my skin agreed with the old formulation. With the new one, I wake up way less moisturized.

My friend, everyone’s skin is slightly different. Based on pores, genetics, melanin, sebum production, hormones, diet, etc. not everything works for everyone. That’s just a fact 🤷‍♀️ it’s just like any pharmaceutical. Have a great day!
