Getting acne....Q&A............(part 3 of 5)

I’ve started getting acne spots. How long do they last? This depends on what type of spots they are and, even then, it can be very difficult to predict what will happen. Some spots will appear and then disappear during the course of a day but others will evolve more gradually through the various stages. Comedones can be very persistent if they don’t get inflamed. Mildly inflamed spots will last 5–10 days before settling down, but can leave a flat red mark (macule) for several weeks. Nodules and cysts may last for weeks or months unless you get some treatment. What is the difference between a whitehead and a yellow- head spot? These two common terms describe quite different types of spot.

Acne:Living in an oil-free world

Is your cosmetic really, absolutely oil free? On the assumption that sebum is a beneficial component of the skin, chemists have tried to imitate this substance, but the “oil free” claim isn’t exactly valid and can be misleading because the oil substitutes that are used in these products are synthetic and are considered to be more harmful than the excess sebum found in the skin that can block pores.
The alleged bad guys
Generally speaking, the most acne-causing cosmetics are:
  • Foundation makeup
  • Pressed powders
  • Thick creams
  • Blushers
Moisturizers can also be a source of acne-producing substances. In order to make these moisturizing products smooth onto the skin easily, they’re often manufactured with ingredients such as acetylated lanolin, searic acid, and cetyl alcohol. All of these ingredients
are considered to be comedogenic.
The alleged good guys
The recommended moisturizers are those that have a base of petrolatum or mineral oil. Powder blushers are usually preferred over creams, and cream/powder foundations are usually preferred over the liquid type because loose powders help to “mop up” the oil. If a liquid foundation is chosen, it should be silicone-based (containing cyclomethicone or dimethicone).
