Good skincare for us regular joes would be: twice daily cleanse and moisturise. Cleanser should be gentle and have no alchohol, perfume or soap in it. Moisturiser should be light and easily absorbed and have no perfume - very important for oily skin as oily skin is often reacting to a lack of moisture.

Makeup brands are not that important - more expensive ones last longer and the colours are better (more natural shades, more dense pigment etc) but there is a lot of variety out there!

A nice simple makeup regime would be:
#1 Cleanse and moisturise - remember lips!
#2 Apply foundation lightly working outwards from the nose. Make sure your foundation is a good match, yellow undertones are best (no one has a red/pink skin tone unless the skin is irritated - and then you want to hide it!) even for very light or very dark skin.
#3 Apply a lighter shade or highlight product around your eye area, I find that often asian skin tones tend towards a dark eye circle? Make sure it is subtle and well blended
#4 Powder lightly to fix the foundation
#5 Black mascara - you can never go wrong with black!
#6 A nice peachy toned blusher on the apples of your cheeks with a fat, domed fluffy brush - blend blend blend!
#7 Bright lip gloss! Shiny glosses only look good on younger people so take advantage!

MAC do good shades of lippy, blusher and do some fabulous masacaras. I like silicone based liquid foundations - L’oreal do some good ones that are quite affordable and come in good colours. More expensive brands like Estee Lauder and Clinique are very popular, but quite pricey. Try to avoid very heavy, thick foundations. Stick with lighter formulas! And dot it carefully over blemishes rather than using a separate concealer - concealors are often oil-based and don’t mix well with your base and dry out the skin.

Best of luck!
