US trend analysts Spate has noted rising interest among skincare consumers for lactic acid serum products.
The New York City outfit said internet searches have grown by 46% in the past year albeit from a low volume relative to other serums.
The US market for lactic acid serum is dominated by three leaders: Biossance, The Inkey List and Sunday Riley.
“In our opinion, lactic acid is the grand master of the alpha hydroxy acids, or AHAs. It can help to improve the texture and tone of the skin, reduce the appearance of fine lines and wrinkles, and promote a more even skin colour,” said a Spate spokeswoman.
“Searches for squalane and glycolic acid reveal that some consumers are interested in combining other ingredients with lactic acid when it comes to this skincare serum,” she added.
Spate also noted rising interest for hair mascara, a temporary hair colour that can be used to cover grey hairs, add highlights, and tame flyaways and frizz.
On average, there are 5,500 searches every month in the US for hair mascara, up 19% since last year.
