Age: 30, Skin type: Dry, Skin concerns: sun spots (hyperpigmentation), redness, and well-aging. This is the 1st L-ascorbic acid product I have used and about 10 seconds after application I feel a stinging sensation. My cheeks turned a light red from the irritation, but even so I chose to continue to use this product consistently (daily before sunscreen and nightly) because my complexion seems more even and my freckles seem to be getting lighter. The texture of the serum is light, soft and easy to spread. For context of the blue picture taken in Feb 2024, I was in an airplane bathroom and found it crazy how the blue light brought out all my freckles and moles. Of course I was disappointed...reminiscing about all my days outside without sunscreen, but oh well, I can only improve from this point on! I plan to use this for at least 2 months and more and take progression photos. I have high hopes! [The normal pics were taken 6/25/2024]

I was very worried about buying this product at the beginning and I did a lot of research. I thought it over and decided to buy it and I have no regrets! I love the texture and the feel of it. It feels kind of like a light cream (due to the formula I suppose) and it absorbs really nicely and doesn’t peel at all (which was a worry that I had). It also isn’t sticky, which is something I love since a lot of serums that I have tried are sticky and take a while longer to absorb but this doesn’t cause me any issues and there is a slight smell to it, but it goes away quickly and it doesn’t linger (which is important to me since I don’t like to necessarily smell my skincare at all) I also believe my skin is a little less dull than before but I’m still going to give it more time to see results. Overall, I really enjoy this serum and I would absolutely recommend it and buy it again.

My skin is just now getting used to this vit c product. I love the way it feels going on and if you wait a couple minutes as the directions suggest, it absorbs / drys down so no pilling!!! I am figuring out whether I’m using too much and finding the right balance. Super excited about c+c. It’s half the price of what I was using before and far seems more effective. Ingredients are key and this has them. It’s only been a few weeks so I’m sure after a few more it’s gonna be as good if not better than my $100 serum I switched from. Happy I found Stratia on socials. Big win

Local, trusted ingredients, a clear and effective formula, and a good price. What else could you want from a vitamin c serum? I use it every morning and have noticed a significant reduction in dark spots and less aging from sun exposure. I've been purchasing for over 6 years and I highly recommend.

I feel like this helps my acne scars fade. I like the soft feeling it leaves on my face.

It spreads easily and absorbs quickly. It's the consistency of makeup primer, very light & airy, and dries matte. It feels a smidge tingly on my skin after applying. I guess that means it's working. It goes away after a minute. I apply once per day in the AM after washing/drying my face. As a new user of this product, I like it so far.

This is my favorite vitamin C serum of all time. It goes on smoothly, feels great. I have been using it about a year now and it has been gentle and highly effective. Thank you, Stratia scientists!

This is good stuff, it stings when you first starting using it but I noticed my skin adjusted quickly.

I really like this. The feel isn’t oily and it doesn’t sting. Also I love the fact that it’s already stable but they also put it into a pump and the container is solid so no light can degrade it. So this hits on all levels for me. Hope this helps!

Leaves my skin soft with no tacky feeling and layers well with other products. It’s also not irritating

I've purchased more expensive vit c settings and creams and none have shown me the results this C+C has! Highly recommend. I'm 52 and started late to skincare but everyone is shocked that I'm not 10 years younger

Love this serum, I can’t even tell you how many people asked what I was doing different when I started using this(okay 2 but STILL), it’s amazing for brightening!

Just started using this but what a fascinating product. The vitamin c products I’ve used previously have all been in a serum format and not a cream. I like this better. I was skeptical but used it as my first product after cleansing and it is so nice because it dries down matte, which left a nice soft touch feeling to my skin before proceeding with my other products. Excited to continue using it and seeing the results.

This serum is so smooth and luxurious, and makes my skin brighter looking. Highly recommend, this and the entire product line! The new toner also is fabulous. Happy shopping at Stratia.

I love this stuff! The consistency is so lovely; it’s almost like a primer and has a silky feel. It instantly calms my redness and evens out my oil production. There’s no offensive smell either, which is great! Definitely recommend.

I love this formula! I have dry/sensitive skin. It tingled a bit for the first couple uses but now I have no problem. I’ve only been using it for a little over a week so can’t speak to the effects yet. It’s silky smooth going on and doesn’t pill under makeup when you let it dry for a few minutes (I wait 10 minutes before applying the rest of my routine). Above all, the customer service is incredible. My package was lost in the mail and Stratia quickly responded and jumped into action. I’m beyond impressed. Thank you Stratia! I will definitely order again. Looking forward to trying their eye cream and rewind serum next!

Brightens my skin. Vit C’s seem to always be a love or hate. My last one was always pilling. I switched to Stratia bc of Alex(Educated Mess)and I’ve never looked back!

I love this vitamin C serum! It brightens and smooths and layers beautifully with my other Stratia products like Lipid Gold and make up. I just turned 50 and this is the boost I needed!!

Science & Key Ingredients.
Vitamin C is one of the most powerful skincare ingredients you can get without a prescription. It can:
• Scavenge and neutralize free radicals
•Increase collagen production
• Fade hyperpigmentation
However, the form of vitamin C that’s easiest for your skin to use, L-ascorbic acid, is also extremely unstable, breaking down quickly when exposed to water, heat, or light. That’s why most vitamin C serums turn orange and need to be replaced often.
C+C Serum uses 10% L-ascorbic acid, and to keep it safe, we’ve suspended it in a lightweight silicone formula away from water, heat, and light. That means it’s stable on your shelf for a full year. We also added 5% ascorbyl tetraisopalmitate, an oil-soluble form of vitamin C.
To up the ante, we added another incredibly powerful antioxidant, Coenzyme Q10 (otherwise known as ubiquinone) to make sure no free radical is left un-scavenged. Bisabolol, a key component of German chamomile, helps soothe and calm skin.
Put it all together and you’re left with an incredibly potent yet non-irritating antioxidant serum to help brighten, smooth, and firm your skin.
C+C Serum does not have a pH because it’s an anhydrous (water-free) product.

12 Days of Ingredients 🧪✨ Day 11: Tocopherol Also known as vitamin E; one of the strongest antioxidants used in skincare. 🧫 Why we use it: Oxidation occurs when a molecule loses an electron through processes like UV radiation, pollution, and smoking. That molecule is now highly unstable and can cause damage to the skin. Antioxidants donate an electron to these free radicals, neutralizing them and preventing damage. Vitamin E is a powerful antioxidant that prevents damage both in the skin and within a skincare formula. #skincareingredients #skincareingredients101 #skinscience #cosmeticchemistry #skincareformulation #12daysofchristmas #tocopherol #vitamine

L-ascorbic acid, AKA the pure form of Vitamin C, is a very powerful ingredient in skincare.  It has been proven to scavenge free radicals, thus reducing damage from UV radiation. It’s also shown to stimulate the production of new collagen in the skin, making it one of the best choices for an anti-aging routine. Plus, it can fade hyperpigmentation by preventing overproduction of melanin. #skincare #skincareingredients #vitamincserum #hyperpigmentation #fadedarkspots
