Warning over 'nasty side effects' of over-the-counter eyelash serums

Over-the-counter serums with prostaglandins became popular after it was found that glaucoma medication with these ingredients could make eyelashes darker and longer.

"Ads for lash serums promise luscious-looking lashes in a matter of weeks and claim products are 'non-irritating' and 'physician formulated'. 'Guaranteed happiness' is also on offer on the box of Flash Eyelash Serum. However, information on the risks of using these products is much harder to find," Consumer NZ chief executive Jon Duffy said.

Consumer NZ reviewed several eyelash serums and found no warnings about the potential side effects on the boxes for products such as the Flash Eyelash Serum and the LiLash - with the only information about the risks written in small print on leaflets inside the sealed boxes (meaning consumers would only be able to read these upon purchasing the product).

Revitalash, another eyelash serum available in New Zealand, tells customers on its website that "there is no potential for the serum to have a significant effect on those breastfeeding, pregnant or undergoing chemotherapy". However, Consumer NZ says te company did not provide any evidence supporting the claims.
