Product Details
C + AHA is a two-in-one daytime antioxidant serum that works by two different mechanisms to help improve the appearance of skin. Formulated with 15% pure vitamin C (l-ascorbic acid) and a blend of 10% hydroxy acids, neutralizes free radicals and exfoliates skin to promote clear skin and minimize the appearance of blemishes. In addition to providing the benefits of vitamin C, this daytime antioxidant serum reduces the appearance of fine lines and wrinkles as it improves overall skin radiance.
- Neutralizes damaging free radicals caused by environmental aggressors
- Exfoliates dry, dull surface cells to help improve the appearance of blemishes and skin texture
- Paraben-, alocohol-, dye-, fragrance-, silicone-, and gluten-free
- Ideal for normal, combination, and oily skin types
How To Use
In the morning after cleansing, apply 4-5 drops to a dry face, neck, and chest. May also be used on the backs of the hands. Finish with a SkinCeuticals broad spectrum sunscreen.

Science & Proof
This daytime antioxidant serum blends the power of pure vitamin C (l-ascorbic acid) with a combination of 10% glycolic and lactic hydroxy acids at a pH that maintains their efficacy on skin. It is formulated under the Duke Antioxidant patent. Vitamin C is a highly-potent antioxidant that is, by its structure, difficult to effectively deliver on skin The Duke Antioxidant patent describes the formulation parameters required for effective delivery of vitamin C to skin: 1) pure l-ascorbic acid (vitamin C); 2) an acidic pH within the 2.0-3.5 pH range and; 3) a concentration between 10%-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.
Key Ingredients
- 15% L-ascorbic acid

As a glycolic acid and the vitamin C from Skinceuticals huge fan I just loved the combination in one bottle! It does not give me acnes as the Vitamin C with CF from Skinceuticals! It left my skin soft and clearer

Best serum I've used with HA ever! It really plumps up my skin and fine lines and makes my skin feel so hydrated afterwards. I would highly recommend this product!

Soy Sauce smell
This product isn't anything special. I haven't noticed a change in my skin. Maybe it takes prolonged use? The product smells like soy sauce and turns dark brown with time. It leaves a brown sheer on my face and can stain clothing. I put sunscreen on top of the product to mask the brown/orange color of my face. I would try something else.

Love this product and I think it’s really effective! It has helped even out my skin tone and brighten my complexion. I had a few acne scars and I feel like it has lightened them.

This product must be used strategically. It can’t be used everyday or it will cause over exfoliation and thus breakouts. It does cause dryness and flakey skin the next day but that’s part of the process. I use it 2-3 times a week and it works so fast. My skin looks smoother, brighter, and less pigmented. It’s the closest thing to a chemical peel without getting one. It’s quite pricey, however you only need two drops and you don’t use it everyday so it lasts a while.

C+AHA is great for my combination skin - I use it at night and spot treat as needed in the mornings if i have any unruly pop-up blemishes. My hubby even asks for 'the special face potion' sometimes! It leaves my skin feeling SO soft looking bright and balanced in the mornings - a great part of my nightly ritual!

Glowing Skin!
I definitely reccommend this product for anyone that has oily or acneic skin. I can say that since I started using this product (about 3 months ago) my skin is softer, smoother and has a healthy glow to it. I get compliments all the time on how great my skin is. I also use the Retinol 1.0 and when I apply the C+AHA the next morning there is some major tingling but it always passes quickly. I love this product and will continue to use it until they stop making it.
