Thinner lips — Make sure you are always replenishing their moisture, and try drawing slightly on the outer edge of lips with a nude lip pencil and using a liquid lipstick product (in lip gloss form but with opaque coverage and staying power of a regular lipstick).
Dark spots / age spots on the hands — Don't forget about your hands! They often show wear and tear of time and signs of aging, as over time melanin clusters in skin's defence
Hydration is crucial — At this stage, it's time to make a major switch to ultra hydrating products that are significantly richer in texture and ingredients. Try creams, milks, and butters. Even eye makeup removers, body or hand creams come in butter forms that provide deep lasting hydration that doesn't evaporate quickly like water-based.
Instead of a regular foundation, try replacing with a hydrating tinted moisturizer
Replace highly foamy cleansers or drying gels with a cleansing milk and use a washcloth to remove makeup instead of water (which is quite drying and low in pH level compared to skin)
