St. Ives Timeless skin. It makes my skin so much smoother and clear. It also exfoliates your skin. I use this at night.
I use Equate Firming Cream at night after I wash my Face with the St. Ives.
I use Equate Anti-Wrinkle Cream in the morning after I wipe my face with a cleansing wipe (I buy the cleansing wipes from dollar tree). I love that it has sunscreen in it.
So for my make-up I go cheap too, I don't notice too much difference with the stay of the make-up and it doesn't irritate my skin at all. Everybody's skin is different though.
I buy my foundation from Walmart or Rite Aid, which ever is cheaper. I just buy the NYC brand. My powder I either buy their or sometimes Dollar Tree will have one that matches my skin color. I also try to buy my eye shadow from Dollar Tree. I think you can not spend a lot on your make-up and still have it look great. I think the key is making sure your colors match your skin tone and knowing how to apply the make-up correctly. What colors go good together and what colors go with your coloring.
