My skin has been looking dull lately, so I'm thinking about using a sheet mask.

Today, on my way home from work, I was shocked when I looked at myself in the elevator mirror. Perhaps because I've been working overtime more often, my complexion was dull and the fine lines around my mouth were more prominent. Before, I used to glow with just a simple toner, but now I feel a definite need for some serious skincare. So, starting today, I'm thinking about starting a more intensive skincare routine, and the biggest question I have is how often to use sheet masks. One sheet a day used to be the trend, but these days, there's talk about how it can damage the skin barrier, so I'm a bit more cautious. I'm curious about how you usually manage your sheet mask routine. I'm worried that too many nutrients can cause breakouts, but maintaining a proper mask mask routine seems quite challenging. Do you prioritize using it before special occasions or do you only use it on certain days of the week?
