Quantity

Best if your vitamin C keeps oxidizing — AA2G is a stable form that won't turn brown or lose potency. The last pump works like the first.

Best for dullness and uneven tone — Helps visibly brighten and even skin tone over time.

Best for sensitive or reactive skin — Works at a skin-friendly pH, so no sting. Unlike traditional L-ascorbic acid serums.

Best if you want defense, not just brightening — Hawaiian Astaxanthin, green tea, and Alaska Sugar Kelp help defend against the daily environmental stress that dulls skin.

How to Use Apply 1-2 pumps to clean, slightly damp skin and gently press into the face and neck. Use morning and night before moisturizer. For daytime, follow with sunscreen

Ingredients

A stable form of vitamin C that helps visibly brighten and even skin tone — without oxidizing in the bottle or stinging on application.

Draws moisture into skin and holds it there, so skin looks plumper and feels hydrated all day.

One of nature's most powerful antioxidants, from microalgae grown in Kona — helps defend skin against daily environmental stress.

Our signature kelp. Its polysaccharides form a light, breathable layer that slows water loss — so skin stays hydrated for hours, not minutes.

Our story

A family brand that's spent fifteen years learning what seaweed can do for skin. That's why we use many different kelps — each for a different benefit.

Customer photo review of Hyaluronic Acid Vitamin C Facial Serum

I love how fast this absorbs and the smell is so unique. I’m only using a short time so time will tel thank you.

Hyaluronic Acid Vitamin C Facial Serum

I thought the Hydronic Acid would hydrate my face and the Vitamin C brighten the skin. However my face feels dryer after using the product. Of course i then use 2 moisturizers to feel better. Instead of returning the product, i decided to keep trying it to give the product a chance to see if over time there would be a difference.

I’ve only been using it for a short time, but my skin already feels so much better, and looks healthier too.

I love this serum, it really helps to reduce the appearance of the pigmentation (freckles and brown spots) on my face caused by years of sun exposure. It is a regular tool in my daily regimen.
