Highlights
Summary
goop's 20% Vitamin C + Hyaluronic Acid Glow Serum combines two skin-care powerhouses, L-ascorbic acid (proven in research to be the purest, best-for-skin form of the powerful antioxidant vitamin C) and moisturizing hyaluronic acid (a hydrator that’s naturally present in the body).
Benefits
- Brightening
- Smoothing
- Moisturizing
- Suitable for all skin types
Features
- There are three different molecular sizes of hyaluronic acid present to penetrate different layers of the skin, as well as the antioxidant superfruit Australian kakadu plum.
- The ingredients work synergistically to help brighten the appearance of the skin, significantly improving its firmness, tone, texture, and hydration and leaving it looking radiant, luminous, and healthy.
- The unique two-part design maximizes potency and freshness, delivering a serum that stays active all the way through its use while staying paraben-free.
- Before your first use, mix the super potent 20% vitamin C powder with the hyaluronic acid serum.
Includes
- Powder (0.20 oz)
- Serum Activator (0.78 oz)
- Dropper (1 ct)

Smooth and hydrated skin
[I received this product in exchange for my honest review] So when I first opened this package, I was pretty skeptical because you have to mix the solution on your own. I was confused because I was thinking if this is so expensive, why do I have to make the solution? But upon further research the pa...

Vitamin Scent
[I received this product in exchange for my honest review] This item was packaged great to ensure it is sealed and not received broken during transit. Also the instructions provided to mix were very easy to follow. My only misunderstanding is that this item is categorized as a serum. My experience w...

A must have!!!
I received this product for free in exchange for my honest review Okay first off prepping this product to actually use it was very nostalgic. I felt like a kid in the bathroom making a potion and I am here for it. Once everything was mixed and applied , my face had an instant glow!! Love love love

Not a fan
[I received this product in exchange for my honest review] I am not a fan. I have acne and this made me break out. If you have acne prone skin I wouldn't use it but you might be different. It has a very watery consistency.
Chef's Kiss to goop 20% Vitamin C + Hyaluronic Acid Serum!
[I received this product in exchange for my honest review] The goop Beauty 20% Vitamin C+ Hyaluronic Acid Glow Serum was the missing item I needed. I currently use a gentle skin cleanser with three dermatologist-prescribed products. My skin has improved could be better. Enter goop Beauty 20% Vitamin C + Hyaluronic Acid Glow Serum! The first photo is from July 2025 and the last two were taken today. Nothing on the skin!! A keeper!



Gorgeous glow
[I received this product in exchange for my honest review] Loved this serum, smooth and easy to use. Left me with a beautiful glowy skin and hydrated. Big fan of he formulation and packaging. Easily one of my favorite items to grab in the morning getting ready.
Overall a really good formula!
[I received this product in exchange for my honest review] I really wanted to like this more than I ended up. I really loved the concept of mixing the activator into the vitamin C powder because it felt more fresh and would last long on the shelf so the whole process of doing the mix was really fun. However it was the end result of the vitamin C serum that I didn't end up, loving so much. I felt like it was kind of sticky in a way that made the application Unenjoyable, and I wasn't a huge fan of the scent. I tried using it for as long as I could to see if I was seeing any results and if it was worth the application process, but I don't really know if I saw any results. it's really hard to tell with vitamin C products in general, but Overall it's just my personal preference about the texture of the end formula when it's mixed together, but I do believe that it is an effective formula nonetheless and if you can get past the stickiness of it, then I think you could really enjoy this!!
