Hey girl! I want to say first I'm sorry for what you're going through and can commiserate here.
I've been experiencing maskne and have combo skin that is typically non-problematic. This is what has helped me:
Personal Face Coverings- I used to use surgical disposable masks but have switched to cotton. The disposable ones are rough and cause "acne mechanica" from a combination inflammation, hair follicles, and humidity. The air pockets these create also makes for a very humid environment which exacerbates the condition. I would use a clarifying mask the night before, go to bed, and wake up with soothed and clearer skin in the AM. However, after removing my disposable mask after only an hour, my skin would look oily, red, and have a million bumps. I have switched to a cotton mask from Amazon. I've heard silk is best on skin so I'm looking into one of those. Masks should be washed nightly with a fragrance-free detergent that you are not allergic to. If you have to use a disposable mask, it should be discarded daily and not reused.
It is important to note that surgical masks are dipped in formaldehyde to sanitize them. I discovered that I am one of the many people who are very allergic to it. For me it causes breathing problems, dermatitis, and typical allergy symptoms that can be quite severe as the mask is literally on your face.
Gentle Products- Counterintuitive as it may seem, you should not use harsh clarifying products on your skin as personal face masks roughen and irritate the skin, and using harsh products after further exacerbate the condition. It is important to know that face masks create inflammation in the skin. The gentler the products, the better. I've started to use SEPHORA COLLECTION Clarifying Peel Pads 60 Pads at night which contain a natural salicylic acid that is gentle on the skin but clarifying at the same time. The bonus is that they work super quickly and are affordable.
Streamlining Skincare Routine- I also stopped using my serums flat-out. I used to use a pre-serum, serum and moisturizer, which made my skin look great. Serums actually draw moisture from the air which is how they make your skin dewy. Using a face mask creates a greenhouse on your face, and adding serums just makes up the humidity and congestion on your face a million times, leading to zits. I stopped using serums at night too, because my skin just doesn't need it anymore. Now I use toner, moisturizer, eye cream and neck cream. I also double cleanse always now.
Streamlining Makeup Routine- No makeup where the mask touches, especially cream formulas. Powders such as blushes are okay but they won't last. Coverage won't work with a mask because when you remove it, it's gone. I only focus on eye makeup and have stopped with lip colour (so difficult for me!) because they have moisture which gets trapped in the mask, too and cause bumps around the mouth.
I hope these tips help your skin. I advise you to read up on this using keyword searches from what I've mentioned as information seems to be difficult to get. No one wants to flat out say "Masks are terrible for your skin." The key is to not overload your skin with harsh products, because it is making the condition worse and creating a cycle.
I've still not fully recovered from maskne, but my situation has improved a lot and I wish you all the best!
