Using an oil serum for my combo skin seemed a crazy idea, but as I browsed the product ingredients and saw it contains hyaluronic acid, I thought, why not? So I ordered this and incorporated it to my morning routine to see if this could keep sebum at bay during the day. It doesn´t completely, but it does help to delay sebum production, meaning I no longer have to use my blotting papers in the morning but just in the afternoon. Besides my skin looks hydrated and plump during the day. Downsize might be the price for a little bottle, but it might be worth it...
