This science-backed anti-aging ingredient is excellent at hydrating and smoothing skin while bolstering the skin barrier. "Ceramides are naturally found within the skin, but as we age our ceramide levels decrease. This causes the skin to become more thin and fine lines become more noticeable," explains Peredo. "They help to repair and protect the skin barrier by keeping moisture in the skin which slows down the appearance of fine lines and wrinkles. Incorporating ceramides in your routine will keep the skin looking youthful, hydrated and plump."
