How can I manage sudden skin problems?

Lately, I'm struggling because looking in the mirror every morning isn't as enjoyable as it used to be. I used to get back to work so quickly that people would tell me my skin glowed even after an all-nighter. But now, even the slightest fatigue makes my complexion look dull. Skin breakouts, in particular, strike without warning. This often makes me feel unfamiliar with my reflection in the mirror. Small blemishes that would have faded quickly in the past now persist for days, even weeks, making me realize the passage of time. Even when I try to cover them up with makeup, the redness peeking through my makeup makes me sigh. My colleagues all look beautiful, and I worry that I'm the only one neglecting skincare. I apply expensive essences and apply packs, but they only last for a short time, and I feel like time is passing without finding a fundamental solution. The sudden onset of skin breakouts! Every time I experience a slump in confidence before an important appointment, I realize I need to be proactive about addressing them. I'm trying to take my daily nutritional supplements and drink two liters of water a day, but rebuilding my lost stamina isn't as easy as I thought. Every time I cleanse my face after work, the rough texture on my fingertips makes me feel depressed. What could be the problem? I can't decide if I need to completely change my cosmetics or make a major change in my diet or lifestyle. I'm curious to know what you're doing to overcome these persistent skin problems. Do you have any helpful products or lifestyle tips for those struggling with the changing skin conditions? Please share your valuable experiences, even if they're just a little advice.
