I got this because it was one of the products I used two years ago that moisturized my skin without making me oily. However, they came out with a new formula earlier this year. I decided to try it anyways and right off the bat I could tell it was different. The old formula was unscented. I'm sensitive to scents, and the new one smells like strong herbal shampoo. I put it on and it stung a little. I don't have a damaged barrier and none of the new products I've tried have burned at all. This one stung a little. So I ended up just washing it all off. I did not like this product. Just note the dates on the other reviews. If they are earlier than January 2024, be aware that Neutrogena discontinued that formula and the came out with the new one, which is what I talked about in this review.

Great mosturizer!
Tried this out of curiosity with my mom, both of us were pleased with our results. She has normal to dry skin and I have combo skin with fungal acne. She uses this everyday as soon as she gets out of the shower; without it her skin would feel dry as a desert. In my case, I put this on after using the Cetaphil daily facial cleanser. I know this product isn't fungal acne safe but I have combo skin, so I put it on the areas of my face that instead of having fungal acne, are kind of dry (mostly my cheeks, nose and neck). This moisturizer makes my skin feel refreshed, hydrated and healthy. It definitely has fragrance, but It's nice and light. I won't give it 5 stars just because it isn't fungal acne safe:)
