Sun exposure, especially prolonged exposure is one of the most common causes of skin reactions in people with sensitive skin. Broad spectrum sunscreens are an important tool in protecting the skin from UV exposure, and is a practical solution. It’s also important to protect your skin in other ways as well; simple sun avoidance when the sun is high, and keeping your skin covered with longer sleeves are other common sense ways to protect yourself.
The key things that dermatologists look for, are the ingredients. Generally, the less the better. Unfortunately, sensitive skin is not a defined condition with a defined singular solution. We can recommend the products that are more likely to work, but you may need to experiment a bit to find out what works for you.
