Sensitive skin may have widened and shallow blood vessels. The amount and location of these can vary, but often they are seen on the cheeks and on or around the nose. If you have shallow blood vessels, it is important to remember to avoid products that increase circulation, such as active serum. It can be advantageous, if you suffer from thin skin with surface blood vessels, to use an enzyme peel that is gentle on the skin, and make sure that you look for ingredients that are vasoconstricting.
Alpha-bisabolol and mariatic thistle are examples of ingredients that are vasoconstricting Also, caffeine acts as an antioxidant when applied to the skin, has a vasoconstrictive effect and protects against free radicals. Caffeine can therefore help to reduce redness on the skin where superficial blood vessels are present.
