    \n
  1. Oily (O) vs. Dry (D)<\/strong>: Measured by sebum production and hydration.<\/li>\n\n\n\n
  2. Sensitive (S) vs. Resistant (R)<\/strong>: Measures how easily your skin reacts to external stimuli.<\/li>\n\n\n\n
  3. Pigmented (P) vs. Non-Pigmented (N)<\/strong>: Propensity to develop freckles, sunspots, or melasma.<\/li>\n\n\n\n
  4. Wrinkled (W) vs. Tight (T)<\/strong>: Indicates the rate of aging and skin elasticity.<\/li>\n<\/ol>\n\n\n\n
