A barrier-safe form of vitamin C (SAP) that delivers visibly brighter skin and improved texture. It absorbs efficiently and is more stable than L-ascorbic acid — less prone to oxidation, so it stays potent through the bottle. Ideal for daily use, and kind to acne-prone skin.
These potent antioxidants offer a compounding effect when combined with vitamin C, improving the efficacy of the formula. Together, this gold-standard trio delivers stronger protection against oxidative stress and visibly brighter skin.
Holding up to 1000x its weight in water, this humectant binds moisture to the skin, plumping and reducing the appearance of fine lines.
These calming botanicals help soothe skin and reduce visible redness while supporting a healthy moisture barrier.

Most users report noticeable improvements in skin texture and tone within 4-6 weeks of consistent use, with full results taking up to 3 months. User results may vary.
Yes to all three. The old rule about vitamin C not mixing with niacinamide comes from a lab scenario, not a bathroom shelf — use them together freely. Retinol and exfoliants are best kept to your evening routine, with the serum in the morning. That is not a compatibility problem; it just gives each active a clean run.
We commissioned an independent 8-week clinical study at Essex Testing Clinic (34 participants). Here is everything it showed:
And 0% reported irritation — across the entire 8 weeks.
Yes. This serum is non-comedogenic and kind to acne-prone skin — it works for all skin types, and can improve the appearance of acne discoloration over time.
It arrives with a natural amber tint — that is the formula on day one, not a serum that has turned. We use sodium ascorbyl phosphate (SAP), which is more stable than L-ascorbic acid and less prone to oxidation, so it holds its potency through the bottle rather than browning on your shelf in a matter of weeks. Keep it out of direct sun, and replace it about six months after opening.
The Vitamin C Serum is a thin, gel-like serum that absorbs quickly and easily into skin.
While we recommend using it in the morning, it can also be applied at night if you are not using another serum.
Yes, our lightweight, fast-absorbing formula makes it an excellent base for makeup.
No synthetic fragrance — ever. What you smell is the formula itself: konjac root, chamomile and clary sage give it a faint botanical aroma that dissipates within a minute of applying. If you've been avoiding vitamin C because of the smell, this is the one to try.

I've only been using the Vitamin C serum for a few days but I already notice that my skin looks just a bit healthier. I can't wait to see what results come after using it for a few weeks.
The Vitamin C Serum is the first product I've ever found to actually reduce the blotchiness on my cheeks. Before using, my cheeks looked sort of burned with uneven tones. The Vitamin C Serum is doing a wonderful job evening out my skin tone. I finally feel like my face is becoming what I've wanted it to be. Mad Hippie, you have my gratitude, thank you.
I am loving all of the Mad Hippe products. This serum is particularly great on my skin!
The best vitamin C serum I've used!
I love this and my skin does too!
It's so much brighter!
I then apply the Mad Hippie Super A Serum and this is great for my skin.
Fine lines are softening up!
I definitely keep purchasing both!
the Mad Hippy Super A Serum
I am so happy I decided to give Mad Hippie a try! This serum is the best thing I’ve ever bought. It has worked wonders to even out my skin tone which I very much need at 65. I would suggest using it under your face cream as it tends to not be absorbed as well if applied over it. I love that the products are not tested on animals and are very reasonably priced. I’m sticking with this company and can’t wait to try other products.
I have great appreciation for your skincare products and your commitment to making them available at a reasonable price. Keep up the good work. Additionally the packaging and care taken in sending the products couldn’t be better. THANK YOU!
I’ve been using the Vitamin C Serum for just two weeks now. I don’t see any visible changes in my skin yet. My guess is because it’s to soon. I do love the scent and the way it feels on my face. A little goes a long way and the price point is great compared to other serums on the market.
The reason for four stars. I’d like to see some changes in my skin before I give it that 5th star.
I am very happy with the C serum so far!
Makes my skin feel beautiful
Love it!
Love the Vitamin C Serum. With this crazy heat in Florida, the serum keeps my skin nourished and young looking. Love it!!
Its awesome!!!!
Great product for price. Not much needed to fully cover and treat the whole face and neck. Definitely recommend.
Great serum. This serum is thick and dries nicely!
This product is a game-changer! Really helps even out skin tone and moisturize.
Have been using Mad Hippy products for over the year. Started with the cream mineral blush/lip tint and now using about 5 products daily. I use the vitamin C serum mixed with the anti oxidation serum. The combination boosts the moisture in my skin.
I have used this for a couple of years and love it! It has reduced the redness that I have.. I have recommended Mad Hippie to several friends
Love
It's amazing stuff! I love it!!
love starting my morning with this!
Love this clean brightening serum. Same ingredients as Skinceuticals serum minus the additives and the steep price. A little sticky but only right after application and gorgeous result
I’ve used it for years and won’t ever stop. My skin looks so young and fresh— at 74! Mad Hippy is the cleanest, best Vita C on the market.
My day can’t start with my Vitamin C! I love how my skin feels after using it. I will continue refilling for as long as she keeps my skin so happy!
i LOVE THE PRODUCT, LOVE EVERYTHING ABOUT MAD HIPPIE!
Amazing product!
I just absolutely love how this feels and looks. A little goes a long way
Very soothing and light. Great smell. Seems to be helping my skin already.
Love the product. So soothing and refreshing.
This is my second purchase of the Vitamin C serum. I love it! I have pretty sensitive skin. It helps brighten up my skin and doesn't clog my pores.
I love the product! It’s a light serum that doesn’t feel like I have put anything on my face absorbs quickly. Better complexion since I started using it.
Nothing in here yet.
A routine builds itself faster than you’d think.
