This is going to be all about skincare products from the drugstore or is just inexpensive products that I have tried that stands out among its kind. This is aiming mostly toward combination-oily skin people, because I have oily skin. And one more thing, the prices for every products may vary from stores to cities.

Exfoliator- St. Ives Blemish & Blackhead Control Apricot Scrub($3.49)
Toner- L'Oreal HydraFresh Toner Alcohol-Free($6.99)
Moisturizer w/out SPF for Acne- Neutrogena Rapid Clear Acne Defense Face Lotion($6.99)

Regular Moisturizer w/ SPF- Clean & Clear FINISHES Pore Perfecting Moisturizer Oil-Free SPF15($7)
Mask- Queen Helene Mint Julep Masque ($3.79)
Spot Treatment- Clean & Clear Advantage Acne Spot Treatment($7.49)
The only categories that I could think of that I skipped are eye cream, night cream, and day cream. This is just because I haven't tired any drugstore or inexpensive creams. For creams, I really invest in those since they are about wrinkles and I do not want wrinkles. So I would suggest to invest in a really good cream even if they are like $50+. It is totally worth it for long-term effect.
