Many contributing factors may cause your foundation to oxidize—skin texture, cleanliness,
natural oils, and even how a foundation appears once applied, dries, and is mixed with oxygen.
Luckily, there are things you can do to prevent this.
- Create a Clean Canvas by Washing Your Face
- Don’t Skip Toner
- Apply a Primer to Grip Your Foundation
- Choose Water-Based Skincare Formulas
- Choose the Right Foundation. If your favorite foundation oxidizes, get a shade lighter
than you normally wear. - Use an Applicator, Not Your Fingers
- Blot Away Excess Oil both before and after foundation application.
- Use a Setting Spray or Powder
- Avoid using a foundation that lasted on your shelf for more than 18 months
- Clean Your Brushes
Topical salicylic acid treats acne by reducing swelling and redness and unplugging blocked skin
pores to allow pimples to shrink. It treats other skin conditions by softening and loosening dry,
scaly, or thickened skin so it falls off or can be removed easily.
