I have always had sensitive skin. My skin has had reactions to everything from jewelry to makeup. It can be a real pain! Here are some things that I do to cope that may just help you as well.
Do you think you have sensitive skin? People with sensitive skin tend to have reactions like stinging, redness, and drying (among others), or can be those that have rosacea, psoriasis, or eczema. For me, I don't have anything serious, but just wind up with reactions.
First, I have learned that the least number of products is the best number of products.
For instance, I don't use a primer with my foundation. Instead, I use less foundation by adding in my daily SPF cream and mixing the two together. There is better coverage and I have great protection from the elements.
Another example of using the least number of products is that I only use certain products in my nighttime skin routine and don't mix with things that I may try that have just come out or that I might want to dabble in. Instead, if I want to try something new, I am sure to only use that particular product and not mix it with my other products until I am sure that I won't have a reaction to its ingredients. Then, should I have a reaction, I am sure what the product is that I may be having a reaction to.
Something else that I have learned is that my skin doesn't need a ton of exfoliating and that I should not over wash my skin. Just the opposite. I have a daily and nightly routine, but I keep it very simple.
Also, when I try something new, whether it be food, cosmetic, jewelry or other things, I am certain not to try a bunch of things at the same time. This helps me to know what a potential reaction may be caused by.
Some people will find that they are allergic to certain ingredients. For me, jewelry items cannot be nickle. They cannot contain nickle at all. Paying attention to what things may have in common that you have a reaction to can save you a lot of time and trouble (as well as money).
Overall, I stick with the same brand of eye shadow and blush, as well as other makeup items. They have hypoallergenic items and I trust that they will not irritate my skin.
Lotions will a lot of scent are not beneficial to me and cause me to break out into hives. Eye shadow with glittery stuff makes my eyelids break out into hives. Certain foods actually cause irritation of my skin. There is a lot I have learned in almost 50 years of being me.
The best advice? Pay attention to yourself. Get to know yourself. Then, treat yourself well.
