Facial masks, enormously popular with beauty-conscious women and men, have been given a clean bill of health in a Consumer Council test report.
The outcome of the test is in sharp contrast with one some three years ago, in which excessive levels of bacteria were detected in some of these skin care products.
The latest test affirmed that all of the 30 models of whitening and/or moisturizing facial masks were in compliance with the Mainland's Hygienic Standard for Cosmetics 2007.
Though all samples passed the test in hygienic standard, 9 of them were detected with minute traces of bacteria of 10 colony forming units per gram or per ml - a level well below the permissible standard of 1,000 cfu/g or ml.
The use of unhygienic facial masks with excessive bacteria on areas of open wounds or near the eyes could result in high risk of infection.
In addition, 2 samples were also detected with trace amount of salicylic acid, used as an antiseptic and preservative in cosmetics, of 0.44% and 0.021% - both within the standard of less than 0.5%.
Unlike the previous test, no migratable fluorescent substances were detected, which when used on the face might migrate onto the skin posing risks of allergic reaction to some users.
Also absent were yeasts or moulds, another indicator of the extent of contamination, if any, and the general hygiene condition of the product.
Overall, the microbiological content analysis of the test has shown significant improvement in the quality of these products.
The Consumer Council is, however, critical of the lack of vital labeling information on expiry dates and names of ingredients in some samples.
It was found that out of the 30 samples, 6 bore neither manufacturing date nor expiry date while 10 carried either one only.
The information is considered crucial to ensure consumers use the products in their best condition, and to avoid using products that have deteriorated.
On labeling of ingredients, 3 models were found without an ingredient list while 1 provided the list in Japanese only.
Ingredient information is important to people allergic to certain substances. Consumers with sensitive skin are advised to cut small pieces of the facial mask and apply in the neck or the side of the face to test if allergic reaction occurs before use.
In the absence of law mandating the labeling of such information on cosmetics, suppliers of facial masks are urged to do so voluntarily to safeguard the interests of consumers.
Vast differences in price were found amongst the facial mask models, ranging from $3.3 to a high $100 a piece.
Consumers are advised to follow the directions for use. Put the mask on the face as instructed and discard after use.
It is not advisable to leave the mask on the face for too long. And, using facial masks daily is not recommended by dermatologists.
If irritation occurs, stop use and consult a doctor if necessary. Do not apply on burned or damaged skin.
