If you're looking to target multiple skin concerns (for instance, dullness and blemishes), then it is possible to layer up your acids for a customised skincare experience. "Most acids can be used together and are synergistic. So, yes, it's okay to mix acids if you're trying to address multiple skin issues at once," says Colbert.
Thomas concurs: "Yes, it is possible to mix acids. … But first you need to use an individual product for a little bit of time to make sure your skin is happy with it, then you can slowly add your next active product and so on." Tread carefully, though. Overusing acids can lead to sensitised skin, so keep an eye on rashes or irritation, and stop using your acids for a while if needed. "The only acid to use in this situation is hyaluronic acid because it's super hydrating," says Colbert.
With no signs of the popularity of acids slowing down, there's been no better time to experiment with new formulas to supercharge your skincare routine. "We need good, regular exfoliation, and used acids tend to be the best option for this," says Thomas. "Once something becomes normal, we tend not to get excited about it, but, for sure, acids are here to stay."
