If I’m keeping track of scores, I probably shelled out 3 to 4 times more moolah on makeup than on skincare products. Believe me, I’m really cheap when it comes to taking care of my skin. But that’s then, this is now. I realized that makeup would on look good if the skin underneath it all is a worthy canvass. Now, I try to invest as much on products that are sure to make my skin pimple-free, blooming and keep oil at bay all day long.
Like makeup and your favorite pair of jeans, you have to know your type to fully assess what your skin truly yearns for. There are basically, 4 skin types and below are the suggested kind of products each skin type should opt to use. By the way, this is in preparation for my first fan mail answer post regarding skincare.
Let me share, again, the things I learned from reading beauty books and articles online.
DRY SKIN
Characterized by: Dull and flaky normally due to dead skin build up, tight pores and the skin feels tight after washing.
Cleansing: Use a mild, creamy, soap-free facial wash at night and avoid washing the face more than twice a day to prevent further drying. Also, avoid extreme water temperature (ice cold/super hot) as it makes the skin even drier.

Toner: Stick with alcohol-free toners.

Moisturizing: Opt for creams rather than regular lotions. Dry skin can handle major hydrators like silicone or ceramides as they prevent moisture from escaping your skin. I sound like a professor with all those big scientific words. LOL! 
OILY SKIN
Characterized by: Enlarge pores, usually prone to acne and breakouts, and frequently looks shiny an hour after washing.
Cleansing: Wash face with gel-based cleanser with potent ingredients like salicylic acid to get rid of dead skin and dissolve the excess sebum that clogs the pores which causes acne and breakouts.

Toner: Use alcohol-based toners or astringents.

Moisturizing: Always choose a light, non-comedogenic, gel-type water-based moisturizer to lock in moisture without clog the pores.
NORMAL SKIN
Characterized by: Has the tendency to lean towards combination skin but with less oil in the T-zone area.
Cleansing: Wash twice a day using a gentle soap-free water-soluble formula that would retain your skin’s natural moisture.

Toner: Go for pH-balancing toners.

Moisturizing: Pick a lightweight product that is non-comedogenic to prevent pimple breakouts.
COMBINATION SKIN
Characterized by: Medium-sized pores and oily in the T-zone area (forehead, nose and chin) while the cheek area is dry and has tight pores.
Cleansing: Opt for an oil-free foaming cleanser with salicylic acid that will get rid of the excess oil without making the dry area even more drier.

Moisturizing: If the dry areas are super flaky and irritated, use a products specific for that area; light moisturizer for T-zone and heavier cream for the dry area. If the dry areas are only mildly dry, treat your skin as if it were oily.
