SAN ANTONIO -- Halloween Warning! The makeup you put on your kids' faces this Halloween could contain banned and harmful chemicals.

But is it really a cause for concern? Some local experts said there's no need to worry.

At Party City, just off NW Loop 410, they sell and apply a lot of Halloween makeup.

"When one of my associates is done with that she is going to have a big gash up above her eye and below her eye," said General Manager Erik Reynolds.

He said he's never fielded a single complaint about the safety of their makeup.

"I've been with the company for 12 years and I've never ever had an issue or a customer ever call to say the makeup harm them in anyway shape or form," he said.

"The bottom line is makeup is generally safe," said the Medical Director of the South Texas Poison Center, Sharn Varney.

But the study by the Breast Cancer Fund said it found chemicals like lead, cadmium, styrene, and formaldehyde in half of the products it tested.

How much of a problem is that?

"Take it into perspective the amount of these substances found in makeup is very small and it's applied to your skin for a very short time," Dr. Varney said.

The study said darker colored makeup had more chemicals and a higher concentration than lighter colors. But even with those, experts said there are plenty of other things you should worry about on Halloween besides that.

"You have more of a chance of having a bad outcome from eating a piece of candy and chewing on it then you would from choking on the makeup," Dr. Varney said.

The South Texas Poison Center said if you have any questions about something your child gets into to call them at 1-800-222-1222.
