I was surprised by my appearance in the photo, so please recommend some management items.

Hello. It's already the season of cold, snowy weather. Last weekend, my nephew's wedding was in full swing, so I wore a hanbok (traditional Korean dress) for the first time in a while and put on some serious makeup. Under the wedding lights, I thought I looked fine, but when I saw the photos I received today, I was truly shocked. The fine lines around my eyes and the lack of elasticity in my neck were so clearly visible. While aging is inevitable, I feel like I've neglected myself too much, and I'm feeling frustrated. It's time to get some serious skincare recommendations. I usually just apply whatever moisturizer I have at home and believe my skin is naturally flawless, but seeing myself in high-resolution photos has given me pause. My friends all have radiant, plump skin, and I feel like I'm falling behind. I'm looking for a product that's rich in nutrients but not too overpowering. Could you recommend a trustworthy skincare product that you've personally used and found to have firmer skin? Rather than resorting to fancy treatments, I'd prefer a basic product or mask that I can use daily in the comfort of my own home. What skincare products have been most effective for you in your mid-fifties? If you've experienced any changes in skin density with consistent use, please share your insights.
