The 10% Azelaic Acid Booster by Paula's Choice is designed to address various skin concerns, including acne, redness, and dark spots. Azelaic acid is known for its exfoliating and brightening properties. The product is dermatologist-tested and non-comedogenic, making it suitable for most skin types. However, it does not offer sun protection, so it's essential to use it alongside sunscreen during the day.
