As with any product that contains retinol you definitely need to apply sunscreen, especially if you use this during the day. But, it's important to use sunscreen all over your face everyday in general if you use any products that contain light sensitive ingredients like retinol, glycolic acid, salicylic acid, vit C whether you apply them during the day or not to avoid damaging your skin and undoing the good these ingredients have done. I personally prefer to apply this and any other products I use with light sensitive ingredients only at night. It's just easier that way and I have less product on my face throughout the day.

This product contains a specially sourced form of retinol that is photostable, meaning it doesn't cause light sensitivity. However, you should always wear sunscreen daily, no matter what products you use!

I would use a sunblock during the day to be safe. You never know how badly skin exposed to retinol will react to the sun, plus skipping sunblock means you may get more pigmentation in the area you want to fix.

As this is a serum it is best used underneath an eye cream and one with an SPF will protect your skin better. You may want to use this serum at night only if you do not wish to use an eye product with SPF.
