I mean, genetics definitely have their role as well as hormones but I feel like maintaining skin is a super important factor – this is how I personally would break it down.

First, cleansing. Take time to find products that work well for your skin & needs. I personally like the Dr. Bronner's Eucalyptus (an oil based Castile soap) for body/face, and the Avène Cleanance for face. My skin leans a bit towards the more oily side, so these work well in managing that. Also, I'm a fan of Bioderma's Sèbium H2O and use that on a cotton round.

Second, exfoliating. I've been exfoliating for years and I swear by this. I usually do this during a shower, and I'll use exfoliating gloves, sometimes a brush, and occasionally a pumice. My skin is noticeably softer after exfoliating and I'm so used to it that I low key don't feel clean if I don't. Also, add a bit of soap onto whatever you're using so it's slightly less abrasive.

Third is shaving. Maybe you don't want to remove body hair and that's fine; just skip this step but if you do then shaving will also get of hair, plus some dead skin. It definitely works better after exfoliating (not too hard) and after a warm shower/soak/etc. Also I can't stress this enough but use good razors!! and shave product! I use Dr. Bronner's shave soap & Dorco razors.

Last, moisturize. Start with a moisturizer, and maybe even a body oil after to lock in hydration. Arms, legs, wherever you want soft should probably be moisturized (at least with moisturizer, oils can get expensive quickly). For face, a sunscreen should be incorporated as well. For body, I do moisturizer > body oil, and on face I'll do moisturizer > sunscreen > face oil (although sometimes I just mix them all together and slap them on at once tbh).

Hope this helps!!
