Working on Deep Wrinkles Great Results
I really like this product, it’s been working well on deeper wrinkles, especially on my forehead and around my smile lines. With consistent use, I can see a noticeable improvement in how my skin looks.
The texture feels hydrating and smooth, and it absorbs nicely without feeling heavy. It leaves my skin feeling softer and more refreshed after each use.
I also like that it helps with overall skin appearance, making it look more even and a bit more radiant.
Minor note: Results take consistency, so it’s best to use it regularly to see the full effect.
Overall, this is a great product for targeting fine lines and deeper wrinkles. Hydrating, easy to use, and delivers visible improvements over time.

Didn’t live up to the hype.
I had high hopes for this product. I’ve seen it all over social, but for me it didn’t live up to the hype. Although it is very moisturizing, it never dries down. There’s no way I could apply makeup over this, as the ads might lead you to believe. If you want a good night time moisturizer then this product is for you.

No Good
So I got this under the impression by the videos online that this was really concealing under the eye and it’s not…very oily and hasn’t done anything for under my eyes at all! Scam!

Pleasantly surprised
I’m two jars in and love it. I do use Botox, retinol, a good face wash, wash moisturize twice daily, etc etc. I struggle with moisturizer because I’m prone to breakouts. Idk what it is about this one but my skin loves it. It feels refreshed and soft. Added bonus, my eyebrows and lashes have gotten longer and darker quick! Obviously we all respond differently to products but I’ll be keeping this in my rotation
