Kacie asks…How about Neutrogena rapid wrinkle repair eye cream? What ingredients are supposed to be brightening my dark circles?
The Right Brain responds:
This product claims to do the following:
- Fade the look of stubborn crow’s feet
- Brighten and even under eye area
- Smooth fine lines & texture
- Reduce the look of dark cirlces
The “magic” ingredient here is retinol. As we’ve noted before, you need to be careful not to be fooled when deciding which retinol product is right for you because there are different types of retinoids and not all of them work the same. The best retinol containing products use a time-released form which ensures there’s enough of the ingredient delivered to your skin to help increase cell turn over without being irritating. This Neutrogena product contains a “sustained release” form of retinol which claims to do just that.

i think crows feet looks lovely and delicate sometimes you just have to own it!!
I don’t know how time release formulas differ with regards to concentrations of ingredients, but this product has the two ingredients main ingredients listed nearly last, meaning in my mind that there is barely any retinol (or ascorbic acid) in this formula.
How can you tell by this ingredient list that it contains a “sustained release” form of retinol? I’ve also seen “time released” and have no idea how that’s possible. Does it have anything to do with microencapsultion with some type of silicone or maybe nanotechnology ?
Thanks for replying.
Carla: You can’t tell from this ingredient list, but J&J has their own sustained release retinol technology they use in their Neutrogena and RoC brands. Typically this kind of technology uses ingredients that can form a “shell” around the retinol droplets. The retinol slowly leaches out of the shell so it’s less likely to irritate your skin.
