It has been rightly pointed out that sunscreens have their SPF (for whatever it is worth) labelled on the containers, while such indices are not available on soaps and moisturisers. The practical way to choose a soap or moisturiser is a trial and error method, because it is so difficult to embrace or condemn particular brands. An easier method for the choice of a soap is to allow a small portion of the lather to enter the eyes and compare the burning sensation so caused by different brands. This is a particularly useful method to choose baby soaps.
