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!

Our top choice comes as recommendations from not one but two of our experts. This serum is unscented, making it ideal for sensitive skin, and it sits at a relatively affordable price point. “This combines a kojic acid derivative, kojic dipalmitate, with tranexamic acid, niacinamide, azelaic acid and alpha-arbutin to address dark spots and post-breakout marks,” says board-certified dermatologist and founder of Visha Skincare Purvisha Patel, MD. It’s great for treating post-acne marks, according to board-certified dermatologists Nupur Patel, MD.

Allies of Skin
Azelaic and Kojic Advanced Clarifying Serum
We know a good splurge when we see one, and this Azelaic and Kojic Advanced Clarifying Serum is worth every dime. “In addition to 10% azelaic acid and 1% kojic acid, it also contains licorice root extract, which inhibits the chemical reaction that causes pigment,” says board-certified dermatologist and assistant clinical professor at Mount Sinai Icahn School of Medicine Debra Jaliman, MD. “It also reduces pigment transfer to keratinocytes, and it’s anti-inflammatory so it improves redness.”

Cons: Expensive
Key ingredients: Kojic acid (1%), azelaic acid, hexylresorcinol, bakuchiol
Customer review: “I am loving this product! It helps keep acne at bay, and I feel my pores look smaller. I purchased the product during a sale and it was definitely worth it. Will continue using in my skincare routine.”
Best Firming: DRMTLGY Hydra-Fader
Not all kojic acid serums have the added benefit of boosting firmness, which is why we had to include this Hydra-Fader serum. “This product contains kojic acid with ceramides to protect the skin barrier,” says Jaliman. “It also has aloe which is anti-inflammatory, and it’s good for patients with sensitive skin.
Pros: Safe for sensitive skin, hydroquinone-free, lightweight, hydrating

An effective vitamin C serum goes a long way, and this option from Hyper Skin is a hit with derms. “This combines 1% kojic acid with 15% vitamin C, plus bearberry, licorice and turmeric, to target uneven tone and dark marks,” says Patel. It also protects against environmental stressors while refining the appearance of wrinkles and fine lines,
