Ive always like the Mary Kay line. This year I have been on a strict budget so Ive used Oil of Olay products, I still like Mary Kay better. I will be glad when I can get back to using it. They have a great anti-aging line that has alot of different options depending on your skin type and what sort of problem areas you have.
Just a note, Ive used Mary Kay for most of my adult life. Im 33 and I get carded all the time and Im always told how young I look. The funny thing is I get that most of the time when Im not wearing any makeup.
I have zero wrinkles but have been using creams all my life. Start with a good sunscreen to prevent sun damage, then stay out of the sun. I wear sun screen all year around here. Avon's Anew does wonders and there are several skin care lines. When I do get too much sun on the tennis court, I use "Avon Photo Radiance". It seems to reverse the sun damage within days.
For sun spots, go get a chemical peel. Also Trilumen works. It is by prescription.
