Sensitive Retinol Oil.

"This is the Bioma Sensitive Retinol Oil, it's $19. If you have older skin or if you have experience with retinoids I wouldn't recommend it, but if you aren't and this might be your first retinoid product you're thinking about trying, or your skin is very sensitive or you have a lot of other products in your routine, this one's worth checking out. It contains HPR which is very, very, very gentle. It also has squalane in here, it's really nice, really affordable, no scent to it."

"My main issue with it is that it is a dropper formula and retinol is already an ingredient that is very unstable. Now of course Bioma doesn't use true retinol, they use a more stabilized form of it, however dropper bottle formulas are so exposed to air, bacteria from the dropper touching our fingers or our face, light exposure. There's a bunch that get stuck up in the dropper itself, which is all fine and dandy unless you're dealing with very unstable ingredients like retinol or vitamin C. These types of ingredients I always just say it's better to go for airtight packaging or packaging that really won't expose the entire formula to sunlight or bacteria. I don't see many retinol dropper formulas anymore. Like five years ago there was a lot on the market but I think over time people have adopted more stable packaging. So automatically this product was a pass for me, which is surprising because I love Bioma."
