For some unknown reason, I got this really bad reaction on one side of my face. Can you recommend me any products to relieve the redness?

What products can I use?

Hello! I have this serum sent by Anua, how do I incorporate this to my skincare and how often do I need to use this? Here is my skincare list for reference: 

🌟 Veganifect Barley Gentle Cleanser
🌟 Mixsoon Centella Asiatica Toner
🌟 Mixsoon Glacier Water Hyaluronic Acid Serum
🌟 Purito Wonder Releaf Centella Serum 
🌟 Purito Bamboo Panthenol Cream

How to Use Anua Niacinamide 10%

Randomly received a package from Purito 🙌🙏 a few days ago I have been complaining and asking here for what I need to do because I have really broken skin barrier. Purito sent me these products for soothing and broken skin barrier 😭

Purito

Just got these for free from Anua 😭✨ I needed this badly and got it from Umma Influencers 🙌
