You may be familiar with the risk of over-exfoliation (and even contact dermatitis) that comes with overusing retinoids. This is relatively easy to spot when it happens, as it likely results in redness, dryness, or overall irritation. One of the not-so-predictable potential side effects? Chapped lips. Here, we’ll explain why. This can happen with any skin care product, including cleansers with active ingredients, serums, or moisturizers. According to Landriscina, a few ingredients may irritate the lips: AHAs, BHAs, niacinamide, and retinoids. The latter is especially important to pay attention to, as retinoids are potent products that can do some serious irritation to the skin if used incorrectly. How do you prevent this? Well, there are two ways: Either you can be extremely meticulous about how you apply your retinoid and make sure that the skin surrounding the lips doesn’t come into contact with any of your actives (that includes surfaces like your pillow, as your skin care can easily smear onto the fabric). Our go-to, of course, is the mbg lip balm. This product contains humectants, emollients, and occlusives, which means it will help pull moisture into the lips, soften the skin, and lock in hydration. Occlusives are especially important for protecting the lips against retinoid irritation, acting as a barrier between the two. We should also note that mbg’s lip balm does not have any exfoliating or aggressive plumping agents in the formula; it only folds in gentle, nourishing actives meant solely for moisture. Why is this important? See, many lip balms feature ingredients like salicylic acid or peppermint oil to buff away flakes or increase volume—which is all well and good, but not when you’re hoping to protect the lips from any potentially irritating actives. Not to mention, mbg’s lip balm will help soften the delicate skin on your lips over time, making it a worthy step in your skin care routine. Think about it—you might set aside a separate step for eye cream because that area is especially sensitive, so why not show the same love to your lips? You should choose a simple, high-quality balm that will nourish your lips and create a buffer from the retinoid. Not sure if your lip balm makes the cut? Here are a few reasons your product may be drying out your lips even more and what to look for in a nourishing lip balm.
