Fertility warning over makeup bases, primers

More than 50 percent of makeup bases and primers have been found to contain potential endocrine-disrupting ingredients that may affect sex hormones or potentially impair fertility, according to the Consumer Council.

A makeup base or primer is typically the initial step in makeup routines.

After reviewing 37 models priced between HK$108 and HK$995, the council found that 17 out of 20 models claiming to provide sun protection contained UV filters such as ethylhexyl methoxycinnamate, homosalate and octocrylene that may pose endocrine-disrupting risks.

Only three of the 20 sun-protection models - Guerlain Parure Gold Skin Correction & Protection SPF 50+, Hourglass Veil Mineral Primer SPF15, and Mac Lightful C+ Coral Grass Tinted Primer SPF45 - did not contain any of these concerning UV filters.

The watchdog, citing research by the Danish Consumer Council Think Chemicals, noted that these harmful substances may affect sex hormones, potentially impair fertility, cause genital malformation in newborns, provoke premature puberty, and increase the risk of breast or testicular cancers.

"Vulnerable groups, including pregnant women, breastfeeding individuals, children and adolescents should minimize exposure to these substances," the council warned.

Aside from UV filters, the council's survey found that 13 models claimed to contain cyclosiloxane compounds - which act as emollient, humectant or solvent - constitute the major sources of pollution when released into the environment.

The study noted that 16 of 21 models claiming to contain fragrance have various fragrance allergens, with the council advising individuals prone to allergic reactions to avoid these products.

It recommended that consumer safety-focused groups collaborate with health agencies to create a priority list and enhance awareness through education and outreach.

"At the same time, traders are called upon to improve formulations to ensure product safety and efficacy while enhancing the transparency of ingredient information," the council said.

To wisely choose and use makeup bases and primers, it recommended that consumers test products on a coarser area of the hand to assess their ability and apply them on the inner wrist to check for adverse reactions like itching or redness.

For women preparing for pregnancy or who are pregnant or breastfeeding, the watchdog advised avoiding products with potential endocrine disruptors, it said.
