Mid 30s here
Mine is an odd mix of low and high maintenance (based on priority areas).
So: Harley St dermatologist --> prescription retinoid, azelaic acid, regular check ups, facials, vitamin C serums, eye creams etc.
Body: moisturiser after every shower, hand and foot cream every evening, regular filing and buffing of finger and toe nails (at least a couple of times a week). Neck cream twice daily. Exfoliate once a week, chiropodist sponge once a week. A few pilates classes every week. Shave legs/armpits whenever needed.
But then also:
Hair: cut twice a year but expensive shampoo, oils, hair masks etc. No waxing, pedicures, manicures, massages etc.
All this means that I look natural but the condition of my skin/hair/nails/hands/feet/body is always very, very good.
