- Kakadu C 20% Vitamin C Serum for Face, Ferulic Acid, 1 fl oz | Tocopherol + plum antioxidants • Anti aging • Brightens the look of discoloration • Hydrating • Dermatologist formulated

I love this serum. I normally get two bottles at Costco for less than this. It is really a great serum and works well with my skin very effective.

Very runny liquid, too thin and difficult to apply. Although I'm not repurchasing, I do want to use it up, so I just add a few drops to a dab of moisturizer in the palm of my hand.

This is the real deal! Been using it for years. When you get a great deal on it, buy 2. A little goes a long way.

Excellent product to nourish my skin. It is worth every dollar.

The best Vitamin C serum I've found - and I've tried a lot . I keep coming back to Dermadoctor because the other brands do not measure up - and some of those are much pricier. Scent is light and fresh. Not sticky and leaves a subtle glow. My dermatologist said Vitamin C serum and Retin A cream are the two best products that she recommends for aging and sun damaged skin. After 4 years of using this serum - and trying others on occasion - I'm sticking with Dermadoctor Kakadu C

I broke out wit a red spot on my face. Had to discontinue using it on my face. I do use it on brown spots on my arms. No sign of it minimizing the brown spots yet.

I'm very happy with this product.

I originally Used this before, because it was rated in top brands of this serum. (less expensive than another brand) - so I came back, because as far as I can tell, it is just as effective 👍🏻
