If you frequently deal with bumps and blemishes on your skin, clogged pores may be the culprit. Adding a serum for oily skin to your routine, or swapping your current serum for a non-comedogenic option, is one way that you can help keep your skin looking clear and balanced. The best serums for oily skin typically feature lightweight formulas and contain ingredients designed to address specific skin concerns, such as blackheads, large pores, and unwanted shine. Finding the right oily skin serum for your needs involves identifying which concerns you’d most like to address and finding a formula that can address those needs. Ahead, we’re sharing a look at nine of our favorite non-comedogenic options worth trying to help get you started on your search.What Are Non-Comedogenic Serums? A non-comedogenic serum is a facial serum designed to target skin concerns without clogging the pores or contributing to breakouts (non-comedogenic literally means “not pore clogging”). Because they won’t clog your pores, non-comedogenic serums are well-suited for those with oily or acne-prone skin. However, anyone can use them, provided the formula aligns with their skincare needs. Common ingredients found in serums for oily skin include salicylic acid (a beta-hydroxy acid), niacinamide, vitamin C, and hyaluronic acid. However, the exact ingredients—and benefits—vary from formula to formula. If you have a specific skin concern you’re looking to target, you’ll want to select a formula designed to address that need (more on that ahead!).Who should use non-comedogenic serums? Anyone can benefit from using a non-comedogenic serum, but they’re especially useful for those with oily and acne-prone skin types since they won’t clog pores (some can even help prevent breakouts). Again, the benefits depend on the specific formula you’re using. There are hydrating non-comedogenic serums, brightening formulas, and even non-comedogenic serums designed to help address the signs of aging. The best one for you will be one that aligns with your specific needs and goals. Once you’ve found the right non-comedogenic serum for your needs, you’ll want to make sure you layer it correctly with your other products. A serum is best used after washing your face with a cleanser, but before adding moisturizer, with the products layered from thinnest to thickest. Many can be used both morning and night, but we suggest reading the instructions on the package of the product you’re using for a clearer understanding of how and when to apply it.9 Non-Comedogenic Serums to Shop Right Now
