I am (way over) 50 and I spend my money more on skincare products. I use Perricone's cold plasma and sometimes Philosophy's Help Me. You don't mention skin type; mine is oily with few wrinkles, and I use Bare Minerals foundation. It totally depends on your skin type and what is currently happening with your skin.
I would recommend Tarte ReCreate Anti-Aging Foundation with Wrinkle Rewind SPF 15. This is a great foundation for mature skin and is a natural product at well. Decreases fine lines, brightens skin, increases firmness and elasticity. Also, always remember to wear sunscreen everyday, even cloudy ones, UV rays are the leading cause of skin aging.
@ surgetechgal - Another great anti-aging and firming foundation is the Hourglass Veil Fluid Makeup Oil Free SPF15 (http://bit.ly/h6fDiE). The formulation contains Matrixyl to support the body's natural ability to produce collagen and help reduce the appearance of wrinkles, as well as Skin Tightener ST to improve texture and promote younger looking skin. It is oil-free, parabens-free, fragrance-free, and has SPF 15.
If you prefer a powder foundation, I’d recommend taking a look at Smashbox HALO Hydrating Perfecting Powder. HALO is the first anti-aging powder with the science of skin care built in. It's advanced formulation of pure gold, 48 minerals, 11 amino acids and a powerful peptide deliver powerful anti-aging benefits while the patented hydration system continuously revitalizes skin and provides a hydrated look that won't accentuate lines and wrinkles. The built-in shaver allows for the convenience of a pressed powder combined with the radiant finish of a loose one, and the super-sized brush deposits the perfect amount of powder every time.

If you prefer liquid foundations, I’ve listed two great anti-aging foundations below::
1) Peter Thomas Roth Un-Wrinkle Foundation (my personal favorite) ( http://sephora.com/browse/product.jhtml?id=P242370
2) Clinique Repairwear Anti-Aging Makeup SPF 15 ( http://www.sephora.com/browse/product.jhtml?id=P12
Both liquid foundations provide excellent anti-aging benefits and sun protection.
I hope this helps you.
