SVR - ABC Hyaluronic Acid 2% Vitamin B3 Gel-Lotion
Use as often as you'd like, and at least twice per day. In the morning, apply it before your sunscreen. Let it sink into your skin first - it might take 1-5 minutes because of the rich texture of this product.

L'Oréal Paris - Revitalift Derm Intensives Vitamin C Serum
You can use this product either in the morning or at night, before your moisturizer or sunscreen. You can use it daily, but, in case you notice signs of irritation, reducing the application to every other night might help.
