Skin is also a largely solved problem: use moisturizer/sunscreen/Vitamin C/Retin A, avoid the sun as much as possible, wear sunglasses, drink lots of water, eat healthy + high antioxidants, sleep well, get minor amounts of Botox occasionally for some parts of the face, microneedling occasionally, maybe a face lift (these days a more or less perfected procedure with low risk) somewhere in your 40s/50s. That plan will basically take you into your 60s looking really good. Even if you can't stick to that plan, the various restorative dermatological options will still give you a fantastic result. But most people are some combination of too apathetic, too lazy, too financially-constrained, or too afraid of more invasive techniques.
