Question

Answer
Subject: Waiting time between day cream and sunscreen
Yes, it is recommended to wait before applying sunscreen after using a day cream that contains penetration enhancers like Phospholipid and 1,2-Hexanediol.
Penetration enhancers help ingredients absorb into the skin. Applying sunscreen immediately might prevent the sunscreen from forming an even protective layer on the skin's surface, which is crucial for its effectiveness. It could also potentially increase the absorption of sunscreen chemicals, which is generally not desired.
A good rule of thumb is to wait about 15-20 minutes after applying your day cream to allow it to fully absorb and the skin surface to dry slightly before applying your sunscreen. This ensures optimal performance for both products.
