I always have these really red post acne marks that can't seem to fade using vitamin C or niacinamide or BHA. Every single breakout leaves this really red marks on my face and I have no idea how to heal them, it's all over my jawline area. 😪

Anyone has any recommendation for my concern? I have extremely sensitive skin that turn red very easily so I can't use really strong products or acid products too often as well.

Hyperpigmentation

I know that you need to apply sunscreen every single day, but what if I'm home the whole day with all curtains shut meaning no sunlight is coming into the house, do I still need to apply sunscreen everyday?

Is sunscreen required indoors?

I tried the ordinary azelaic acid, applied it every single day every morning for the past 2 weeks already but my acnes are not stopping, in fact, new ones keep popping out around my jaw line.

Am I using it incorrectly or is this the purging phase? fyi: I'm using a pea sized amount for my whole jawline + chin area since that's where I'm having breakouts

Azelaic Acid

every month period cycle will always trigger new acne forming around my jawline/chin area. is there any way to prevent breakouts during period? or skincare products doesn't help to prevent since its internal body hormonal issue?

Monthly hormonal

How do you perform a patch test for a new skincare product? Because my face skin is extremely sensitive but other parts of my body are not, so if I were to apply it on my elbow or neck or back of my ear it might not have the same reaction as on my face.
