Beautifying Face Mask Cautions
Do not use the mask on broken skin. Do a 10 minute patch test first but remove it earlier if you can feel strong tingling on your skin. If the skin under the patch test is very red but you still want to have a mask, wait at least 24 hours before applying a full mask and only leave on for 3 or 4 minutes. Wait a week or two before applying another mask, but this time leave it on for an extra 1 - 2 minutes. Gradually increase the time of weekly or fortnightly mask applications. Redness or tingling can occur because of an allergic reaction from one or some of the nutrients, e.g. vitamin B3 which may irritate thin, sensitive skin. Regular mask treatments should strengthen your skin.
