We're ALL going to age - part of it is genetic(take a look at one's older close relatives to get a clue), and a good bit of it is lifestyle, as in healthy diet over a long period of time, solid physical program, stress-reduction, and finding something one loves to do. Keeping one's mind open and curious keeps one younger too.
However, in the skin care game, with all the "anti-aging" hype out there, there really are only a handful of types of products that actually make a difference, mainly Rx retinoids, Vitamin C, glycolic acid products, and certain skin-lightening products(like Rx hydroquinone for stubborn hyperpigmentation). Biggest bang for the buck is the Rx retinoid. However, if one is not following up with sunblock daily year-round, any solid skin care like this will be useless, and even harmful. With one or two such actives in one's routine, the rest of one's skin care can be bland and neutral. One doesn't have to spend a fortune for that. As far as procedures go, it can be a slippery slope for some people, because once they have one thing done, then something else comes to their attention they're not satisfied with. Plus one has to keep up this considerable expense every few months.
Hair coloring, and a flattering cut help, skillful makeup, also flattering clothing according to one's general look. And not being afraid to try something new. There's so much advice out there for women to "play it safe" as we age. That's fine, as far as it goes and if that really suits one, but so many times, it just makes women more invisible as we age. We don't need that! A bit of color and flair never hurt anyone!
All that said, I do do the skin care(Rx retinoid and Vitamin C, sunblock, basic cleanser+moisturizer), hair coloring, healthy lifestyle, and I follow my own drummer when it comes to makeup and clothing. Easy for me to do, as an artist!:)
