"Many sunscreens contain fragrances, parabens, and phthalates which can cause inflammation, irritation and contact dermatitis, so checking the ingredients is key for people with more sensitive skin,” says Eleanor Hartley. "Chemical sunscreens work by absorbing photons (light) as it hits the skin, while a physical sunscreen uses minerals like zinc oxide and titanium dioxide to reflect light off the skin."
This is why those with sensitive skin find a mineral (physical) sunscreen is more comfortable for them, as they tend to contain less harsh irritants that create inflammation. When choosing a sunscreen, look for those that are designed for all skin types, or specifically marketed toward those with sensitive skin.
