Avoid soap-based cleansers, toners, astringents, and drying masks.
Always use a moisturizer. Even dry skin can fall victim to acne, however, if the moisturizer is too oily.
Do not use excessively hot water to wash or when you bathe. This exacerbates dryness.
Toners, astringents, and other oil-cutting products may be useful to control overproduction of oil, which can lead to breakouts.
Be careful to not overdry your skin, as this won't necessarily diminish breakouts but will add arid, peeling skin to the mix, as well as subsequent over production by the oil glands in areas like the T-zone.
A relatively new topical product called Tazorac gel is available with a doctor's prescription. The gel shows promise in helping to control oil production.
Use a moisturizer only when and where you need it. Make sure it is water-based, oil-free, and noncomedogenic.
When you can, simply use a zinc oxide- or Parsol 1789-containing sunscreen and skip the moisturizer altogether.
This is the trickiest skin to treat, since it is all about keeping things balanced. Fortunately, for most combo-skin types, the oiliness is centered in the T-zone area, where everyone has a higher concentration of sebaceous glands. Use a water-based, oil-free, noncomedogenic moisturizer, but only in the areas where you need it.
