Hello everyone! I hope you are doing good. 

Please I have a question regarding the use of 2 serums Collagen serum and triple Peptide serum. Can we mix them together? 
For example I use vitamin C in my morning routine but not sure if I can mix it wih Collagen serum or tripple Peptide serum ? 
Also I really like to apply collagen serum at night but not sure to mix it with Peptide altogether?
Do you have aby insights about it ? 

Thank you for help

Can we mix those serums?

Hi everyone !
I hope you are doing all well. 
Lately my skin is going crazy or maybe I am the one who is not recognizing anymore my skin. I have a sensitive combination skin, I follow my skincare routine to the best that I can, currently I am dealing with a "condition" that I am noticing for over 4 months now. My cheeks area are coverd with little red pimples underskin. Only in that area. My forhead and chin are clean and smooth. I only have this condition around my cheeks as you can see in pictures. Not whitehead not blackhead but more of little pimples red and underskin, it doesn't hurt but sometimes I got itchy in some area of my face. I really cant figure out what is it ? Are these fungal acnee ? acnee ? Is my skin barrier damaged ? Is this irritation? Breakouts? 
My routine is as followed:
 Morning
-Mad hippie Vitamine c
- Bioderma sensibio rich soothing cream for sensitve intolerant skin (only if I feel that my skin is dehydrated)
-beauty of joseon sunscreen 

Evening:
-Banila co clean it zero cleansing balm 
-Cerave hydrating cleanser
-Mary&May cica tea tree AHA PHA toner (2x per week)
-Cosrx advanced snail 96 mucin essence Or Mary and May black berry complex cream essence (depends)
-Mary& May Idebenone blackberry complex serum
-La roche Posay Effaclar Duo + 
-Mary&May idebenone blackberry intense cream or la roche posay cicaplast balm (when I feel so).

Even when I was using Somebymi aha bha pha 30 days range I had same condition. When I use also cicaplast I dont really notice any change... 

Do you have any ideas ? Thank youuuu!
