Is there a way to remove the blemishes that bother me every time I look in the mirror?

These days, every morning after washing my face and looking in the mirror, I'm surprised by how different my skin is. My skin used to recover quickly, even after working overtime, but now it's dull and irritated. The blemishes around my eyes and cheeks are particularly noticeable, making me increasingly concerned about how to remove them. I thought I was diligent about applying sunscreen, but was it just not enough? Or is it just the passage of time that's holding me back? I've been thinking about visiting a dermatologist, but the cost and time are prohibitive, so I'm hesitating. So, I'm looking into cosmetics to start with at-home care. However, with so many products on the market, it's hard to tell which ones are truly effective at removing blemishes. I've heard that vitamin-based essences and creams are good, but I'm worried they might irritate my skin. My skin regeneration has definitely slowed down, which is making me anxious. I don't think simply applying whitening products will solve this problem, so I'm planning a systematic blemish removal regimen. Has anyone else had similar concerns and found success? I'm curious about how you usually manage your skin texture and tone. If you have any good tips or products, please let me know.
