Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
Cetearyl Ethylhexanoate is derived from cetearyl alcohol and sorbic acid.
Dimethicone is a silicone used for making products smooth and silky. It also has the added benefit of sealing in hydration. The amount of dimethicone found in beauty products is considered safe and non-comedogenic, meaning it won't clog pores.

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.

Not one of CeraVe's better products. I bought this (along with their eye cream) on vacation when I left all my skincare behind at an AirBnB (tragedy!) and didn't want to replace it all at inflated tourist-area prices. I used it for the two weeks I was on vacation and it did nothing - my face didn't feel particularly hydrated. There are better serums out there.

My dermatologist recommended me this product after finishing my acne treatment pills. I LOOOVEEEED IT. I bought the effaclar serum so I stopped using it. (I was so into La roche posay!!). I would repurchased it again and use it on my night routine (still trying to figure out what to use). It's a bit expensive for me hihi.
