Are all facial serums ophthalmologically tested?

No, they are not all ophthalmologically tested. The European cosmetic regulation stipulates that only products likely to come into contact with the eyes must undergo an ocular irritation test, even though it is strongly recommended for cosmetic companies to do so for all facial products.

Thus, in the market, serums intended for the eye contours are predominantly tested ophthalmologically, but not necessarily those formulated for the entire face. Generally, when a cosmetic product has not been ophthalmologically tested, the label includes the following comment: "Avoid the eye contour area".
