Skin care does not have a one-way-fits-all formula. Everyone has unique skin condition, and each individual difference adds up to your overall skin condition. There are some major types of skin, as illustrated in the image. First step to great skin care is to know your skin type. Find your skin type avatar by matching the attributes to your own attributes.
For simplicity, skin types are divided into 6 major types: normal, dry, oil, combination, sensitive and aging. The first three types: Normal, Dry and Oily skin can be differentiated through its overall complexion (radiant/matte/shiny), water content, oil content and pore size. Water content indicates skin elasticity, while oil content indicates skin softness.
Normal skin in average in water content, oil content and pore size, which makes people with normal skin have little to no problem with their radiant skin. Dry skin looks matte, and it has low water content, oil content as well as small pore size, so people with dry skin can easily become irritated when exposed to drying agents like soap. Oily skin is shiny, it has high oil content and enlarged pore size, which means that people with oily skin are more prone to acne and blackheads. Interestingly, oily skin often has low water content, which they skin tries to compensate by producing much oil.
Combination skin, as the name suggests, has properties from both oily and dry skin. The 'T-zone', which is the forehead, nose and chin area, often takes on the properties of oily skin, while the eyes and cheeks take on the properties of dry skin. Skin care for combination skin often has to be differentiated for different parts of the skin. Sensitive skin is easily triggered by different stimulants like UV rays, harsh cosmetics, hormonal imbalances and become, red, itchy, dry and burning. Senior, or Aging, skin is a skin condition that everyone would eventually have. Senior skin has less volume, elasticity, and wrinkles as well as discoloration may appear. Note that you may have a combination of the skin types, e.g. dry sensitive skin. There are also other skin conditions that fall under 'irritated dry skin', such as ichthyosis or psoriasis.
While each skin type has its own pros and cons, what is important is to work on what we already have. Regardless of our skin type, we can take great care of it and bring out the best in our skin potential.
