I'm trying to completely change my skincare routine. Can you help me out? I'm a beginner.

When I was in my 20s, I could just pick up anything with a sale price tag from the local Olive Young and apply it without checking the ingredients, and my skin would be soft and smooth the next day without any breakouts. But now, after washing my face and drying it, my face feels so tight within a minute, as if it's going to tear, and when I smile, I can even see the fine wrinkles around my eyes.

So, I'm going to take this opportunity to throw away all the cosmetics that are nearing their expiration date from my vanity and start over from scratch with a high-quality, proper skincare routine suitable for adults in their 30s.

What's the right combination of ingredients, and application order, to achieve both anti-aging, wrinkle care, and deep hydration? Beauty YouTubers often say retinol should be applied at night with the lights off, and that mixing it with a vitamin C ampoule will transform your face. Could someone like me, a beginner at anti-aging, please give me a basic guide to the safest and best functional skincare routine to try?

Up until now, I've only roughly applied the three-step order of water toner, essence, and thick moisturizing cream, but I'm also curious if there are any eye creams or serums that I absolutely must add to my 30s skin. It's so sad and regrettable to age early, but I firmly believe that investing money and time in skincare will make a huge difference in my 40s. I eagerly await the community's skin beauties' know-how on their perfect skincare routines! Please leave lots of comments!
