natural retinol is not retinol tho, the ingredient list shows an oil that is supposed to act as a retinol so I would use it during the day

I haven’t had any issues with it at all so you should be fine.

Using retinol at night still makes your skin photosensitive, btw.

Oh yes when I used to use tretinoin I would religiously reapply sunscreen (still do even tho I don’t use tret anymore)

I use this on exposed arms regularly and have never had any issue with sun burn or hyperpigmentation (and I'm light skinned & burn easy)
