The birthplace of AHA Science

AHA science was born in 1974, when the pioneering derms who created NEOSTRATA® were the first to publish the skin-renewing benefits of Alpha Hydroxy Acids. They received a U.S. patent shortly after in 1975, beginning a new era for NEOSTRATA® and skin science.​

A generation-enduring discovery

While treating patients with a severe skin condition, Dr. Van Scott and Dr. Yu unlocked an era-defining insight: Alpha Hydroxy Acids (AHAs) accelerate skin’s natural turnover process to visibly renew skin. This pivotal discovery revolutionised the skincare industry which continues to widely use acids for visible skin benefits, over 50 years later.​
