Determine your skin type is an incredibly important step

To determine your skin type is an incredibly important step because if you buy products that aren't appropriate for your skin, they will be incredibly ineffective. You should also take into consideration specific issues that your skin has, such as acne.

Normal Skin is smooth and firm to the touch with small or medium sized pores. It doesn't get too dry or too oily, and it only has the occasional blemish. People with normal skin should moisturize, cleanse, use a spot treatment, and maybe a night solution.

Dry Skin you have if your skin feels very tight and is noticeably flaky in areas. Dry skin can be caused by lack of hydration or malnutrition. Dry skin can look rough and bumpy, and rarely gets oily. Those with dry skin should find a deep moisturizer, use a spot treatment, and use a moisturizing night solution.  

Oily Skin is easy to identify. If your face is visibly shiny, and literally feels slightly wet to the touch then you have oily skin. Oily skin come with large pores that are more noticeable, and usually is more prone to blemishes. If you have oily skin, you should tone, exfoliate, use a spot treatment, and lightly moisturize once in a while.

Combination Skin be a little of just about every skin type. If you have combination skin, you tend to get oily around your nose, chin, and forehead area, and dry around your cheeks. The rest of your skin may be normal. A lot of people have combination skin. If you are among them, exfoliate, cleanse, moisturize, and use a spot treatment.

Sensitive Skin you have when you burn very easily, have reactions to certain cosmetics, and have irritated skin after a dramatic change in weather. Sensitive skin is very hard to deal with because it isn't as durable as other skin types. You have to thoroughly test products before risking a purchase, and you find blemishes hard to treat. If you have sensitive skin, use a moisturizer, cleanser, and spot treatment all suitable for sensitive skin.
