Facial acids are active ingredients that bring visible and measurable changes to your skin. They're powerful skincare enhancers, delivering dramatic effects you can often see instantly (thanks, Hyaluronic Acid!). When added to other skincare formulas, facial acids help other active ingredients penetrate the skin more effectively, boosting the production of elastin and collagen. This results in stronger bonds between skin cells, enhancing your skin's elasticity and texture.

That sounds better than the kind of acid you might be thinking of, right? But before you use facial acids, it's essential to choose the right ones for your age and skin concerns.

For instance, start incorporating AHAs and BHAs in your mid-twenties. These acids help unclog pores and exfoliate the skin, reducing acne—a common issue in your twenties. Once you hit your thirties and beyond, focus on hydrating and anti-aging acids like Hyaluronic Acid and Vitamin C.

Before applying a skincare acid, ensure it's compatible with your skin type. Test it on your inner arm and wait 24 to 48 hours before using it on your face. If your skin turns red, itchy, or feels like it's burning, don't continue using it.

Facial acids are commonly found in products like serums, face creams, and body washes. Start by using the product once or twice a week, then increase usage once you're sure your skin can handle it. As a general rule, always apply sunscreen after using a facial acid. While acids are safe, they can increase skin sensitivity, making it more vulnerable to UV damage.

There are tons of acids used in skincare formulations. These are some of the most loved in the skincare world, and for good reason—the effects are powerful and, in some cases, almost immediate.

Hyaluronic Acid is one of the most beloved facial acids on the market, and for good reason. Known for its intense hydrating properties, the effects of Hyaluronic Acid are almost instantaneous. You'll notice your skin looking firmer and more supple just minutes after application. It's perfect for tightening sagging skin and reducing fine lines. Hyaluronic Acid is a clear, gooey substance naturally found in our bodies, including our skin, connective tissue, and eyes. While it's often sourced from rooster combs, vegan alternatives exist. We source ours from the Caesalpinia Spinosa plant, a thorny shrub native to Peru. Hyaluronic acid is gentle and beneficial for all skin types, making it a must-have in your skincare arsenal.

Better known as AHAs, Alpha Hydroxy Acids are powerful exfoliants that break the bonds between dead skin cells to improve skin texture and complexion. AHAs act on the cells of the skin's surface, which makes them effective in reducing fine lines, dark spots, and acne scars. They are typically best used on dry skin with surface-level conditions.

Lactic Acid is a hydrating AHA commonly derived from milk. Terre Mere Labs sources lactic acid from vegan alternatives, like flax seeds, that deliver the same result. It's a natural exfoliant, loosening the bonds between dull, dead skin cells to reveal the shiny new cells underneath. As a result, lactic acid is used to brighten and smooth out skin tone. It can also help reduce the appearance of fine lines and wrinkles. Because lactic acid possesses a peeling effect on the skin, sunscreen is key when using this ingredient.

Like lactic Acid, Malic Acid is another natural exfoliant that promotes cell turnover, exposing healthy skin cells with a radiant shine. Malic Acid is also a great option for acne-prone and sensitive skin, since it's typically less irritating than other acids are. However, you should still wear lots of sunscreen when using malic acid. It also acts as a humectant, which traps moisture into the skin and nourishes its protective outer barrier. It also reduces the appearance of wrinkles and fine lines. Terre Mere sources malic acid from vegan sources, such as apples and cherries.

An antioxidant derived from broccoli, alpha-lipoic Acid protects cells from damage and thereby preserves your natural, radiant glow. Thanks to its antioxidant properties, ALA is known as a powerful anti-aging ingredient. It also helps protect skin cells from UV damage caused by sun exposure and other external stressors. What's more, ALA also possesses anti-inflammatory properties, which can help with redness, as well as healing cuts or scabs.

Of all the acids, Glycolic Acid stands out with its tiny molecule size, making it the most effective at penetrating your skin. And that's fantastic news because this powerhouse ingredient seems to do it all. Derived from sugar cane, Glycolic Acid is the most popular AHA in skincare, and for good reason. It exfoliates the skin, reduces fine lines, prevents acne, thickens the skin, and evens out your skin tone and texture. However, it can increase sun sensitivity, so be sure to put on extra sunscreen when using products with this miracle ingredient.

BHAs, like their AHA counterparts, are exfoliating acids, but they work a bit differently. BHAs can reach deeper into your pores to remove dead skin cells and excess sebum. This helps peel away the surface of your skin, allowing new, healthy skin cells to take their place, evening your complexion and texture. After using a BHA, your skin will feel noticeably smoother. They're also a powerful solution for combating acne, redness, inflammation, and sun damage.

Salicylic Acid is the most common type of BHA out there. It's famous for fighting acne, especially mild cases like whiteheads and blackheads. Regular use can help prevent future breakouts, too. Thanks to its exfoliating properties, salicylic acid dives deep into your skin, dissolving dead skin cells that clog your pores and cause acne. Just remember to apply sunscreen when using products with salicylic acid, as it can make your skin more sensitive to the sun.

You're familiar with Vitamin C as an essential nutrient, but it's also a world-class skincare ingredient, too. Its claim to fame lies within its ability to brighten the skin and protect it against harmful external stressors. These characteristics make Vitamin C a potent anti-aging solution, minimizing fine lines and dull, sagging skin. Better yet, it's great for all skin types.

Naturally found in grains like barley, wheat, and rye, azelaic Acid possesses antimicrobial and anti-inflammatory properties, making it an effective treatment for conditions like acne and rosacea. It works by cleansing pores of bacteria and encouraging cell turnover, which allows the skin to heal more quickly and minimize scarring. But because azelaic Acid can thin your skin, it's important to wear extra sun protection while using it.

Conclusion

Though they might sound intimidating at first, facial acids are anything but scary. There's an acid for almost every skin concern, making them fantastic additions to your skincare routine as your skin changes over time. Most are naturally occurring and sourced from plants, and even better, they're powerful skincare saviors with proven results. By understanding and incorporating these incredible ingredients, you can achieve glowing, youthful skin.
