This extract from the seeds of the medicinal plant Psoralea corylifolia is an excellent plant-based alternative to retinol. Studies have shown its efficacy to be similar, if not superior, since it spares the skin from the latter's side effects (irritation, desquamation, redness, dryness, etc.).   

Its activity is powerful and multifaceted. It stimulates the production of collagen I, III and IV, boosts hyaluronic acid and aquaporin, and strengthens the dermal and dermal-epidermal junction. As a result, skin becomes smoother, more elastic, firmer and more luminous.   

It also has anti-inflammatory properties and acts against both lipo-peroxidation and oxidative stress. It thus prevents the appearance of multiple signs of skin aging.​

It is also known for its anti-acne action and its ability to improve skin tone and sebum quality.
