If you have sensitive skin like me, chances are you know just how nerve wrecking it can be to try a new skincare product. I’ve dealt with my fair share of burns, rashes, and swelling as the result of putting certain formulas on my face, so I try to do whatever I can to reduce the chances of it happening again.
Of course, as someone who tests beauty products for a living this is admittedly something that I have to be mindful of. Especially when certain ingredients have a reputation for being a bit strong. Take kojic acid, for example. This ingredient can be extremely helpful for brightening skin and evening skin tone. However, if you use it at a high percentage, it can cause irritation.
Fortunately, there are a number of brands on the market right now that use only a small amount of kojic acid in their products making it sensitive skin-friendly. In other words, you can reap the benefits of the ingredient without the extra worry or stress. So to find out which brands offer effective yet cautiously crafted formulas, I went ahead and spoke with three leading dermatologists to get the best recommendations. Read on for their top picks!
