Too often, the science behind skincare is overshadowed by marketing tactics and myths. At The Ordinary, we believe skincare should be grounded in research, and that transparency matters.
Some of our most-loved formulations also spark the most questions. Using clinically proven data, we bring clarity to the conversation and share exactly how and why they work.
Niacinamide works even better with support. That’s why our scientists combined it with zinc PCA—a combination proven to enhance niacinamide’s delivery into the skin. Together, they help improve hydration and regulate excess oil for clearer-looking skin.
AHAs (alpha hydroxy acids) dissolve dead skin cells for a smoother, more radiant appearance, while BHAs (beta hydroxy acids) penetrate pores to lift away excess oil and debris, helping to prevent blackheads.
Glycolic acid is popular because it works. With the lowest molecular weight of all AHAs, this small but mighty ingredient penetrates efficiently to exfoliate, smooth texture, and brighten and refine uneven skin tone.
Sensitive skin is a concern that affects around 40% of the global population. That's why we combined 8 active ingredients to address each step in the skin irritation cycle, helping calm visible redness, support the barrier, and improve skin comfort over time.
