A Queensland mother claims a Halloween makeup kit she bought at Woolworths "severely burnt" her son's skin.
Alexandra Leigh Carter said she painted her four-year-old son's face with the product on Wednesday evening last week and said it was only on his skin for a couple of minutes before she "had to immediately take him for a shower."
Ms Carter told 7News Online that Mckenzie had complained it was hurting as they were washing it off his face.
Following this she called 13-HEALTH and administered an antihistamine and kept an eye on her son's condition.
She said she had tested the product on the underside of his wrist and left it there for about 15 to 20 minutes, but there was no reaction.
Ms Carter wrote online: "I'd like to share this to warn other parents.
"We did this as a trial run for Halloween and safe to say I'll never be using face paint again."
Ms Carter said she had used face paint on her son previously and had never had any problems.
The mother-of-three said the initial reaction "looked like a chemical burn", but the redness had subsided by the next morning.

However, she said Mckenzie complained for about another day about the area being itchy.
"I'd like to see this product discontinued in case another child has to go through this or the parent that's scared for her/his child," Ms Carter said.
Woolworths said Ms Carter's concern is being taken seriously and it has engaged with her to investigate her concern.
A Woolworths spokesperson told 7News Online: "We always work hard with our suppliers to ensure all products supplied meet the safety and quality standards our customers expect.
"This product has gone through thorough testing with our supplier, and customers should be assured that it meets our stringent quality standards."
Woolworths said thousands of these items have been sold since the product was introduced in early October and confirmed this remains the only concern raised by a customer.
Ms Carter said Woolworths was quick to repsond to her and the product she bought will be returned for further testing.
