This serum is great for keeping the skin balanced and clear. Works well when skin feels oily but also dry at the same time. Helps when there are breakouts, especially stress or hormonal ones. Good for calming redness after a long day in the sun or wearing makeup for hours. Useful when skin feels irritated after using too many products or exfoliating too much. Feels lightweight and absorbs fast, so it works well under moisturizer.
