A Mitchum spokesperson said the brand was “truly sorry some of our customers have experienced temporary irritation”.
In a statement, the company said: “We want to reassure there has been no change to the formula of our products, but we have identified a change in the manufacturing process affecting one of our raw materials.
“This has impacted how the roll-on interacts with the skin of some users.”
It did not give details of what the change to its manufacturing process was but said the issue had since been resolved and it was working to “remove the small amount of product” left in shops.
“In addition, we have reverted to the original manufacturing process to ensure no other batches are affected,” the spokesperson said.
Mitchum advised all those affected to contact its customer services team so it could “make this right”.
