Oxidised Foundation (Why Does Foundation Turn Orange?)
Have you found what you thought was the perfect shade of foundation, only to realise it turned a deeper, orange colour hours after applying it? What causes this to happen, and how you can avoid it, may surprise you.
Why Foundation Turns Orange
The primary culprit for a foundation changing colour is the interaction between the oils on your skin and the pigments in your foundation. For example, a foundation with subtle peach undertones can intensify into an orange-ish hue as the oil your skin produces saturates the foundation—something that can happen within 1 to 3 hours after you apply foundation, although for some it won’t happen until the end of the day.
The same cause-and-effect scenario can occur with face powders whose subtle pigments seem to deepen as they combine with the oils on your face.
What You Can Do about It
Before applying makeup, make sure you start with clean skin. If you have oily/combination skin, opt for an oil-reducing cleanser; if you have dry skin, a lightly hydrating cleanser will do the trick, without leaving your skin feeling tight or dry.
If you have oily skin, prime it with a product like our SHINE STOPPER to create an absorbent barrier that inhibits the oil from interfering with your foundation.
Another thing to consider: It may be that the oils in your moisturiser are mixing with your foundation and intensifying the colour and undertones. Switching your daytime moisturiser to a lighter formula like our RESIST Youth-Extending Daily Hydrating Fluid could possibly help.
What About Oxidised Foundation?
You may have heard someone use the term “oxidised foundation” to describe a foundation that changes colour during wear, but true oxidation actually doesn’t occur that quickly.
However, oxidation can occur in the bottle over the long term (about 6 months to a year after opening). If you loved your foundation in the beginning, but eventually the colour stopped looking natural, there’s a good chance oxidation may be to blame. (All the more reason to treat yourself to a new one!) As a general rule, any liquid or cream foundation should be used up or discarded within a year of opening.
How to Find a Foundation that Doesn’t Oxidise
Your best bet for avoiding oxidation is to select a foundation that is stabilised with antioxidants and comes in air- and light-restrictive packaging to protect the makeup’s stability. As an extra precaution, if the packaging is clear glass or plastic, store it in a dark place to protect the contents from hours of exposure to natural light.
