Like most others have reported, this has made a heckuva big difference in my skin. Many, many moons ago, my first MAC studio fix was NC15. A few years later, I'd moved up to NC20. Then fast forward another decade, and I was NC25. Clearly some long term darkening and sun damage going on, despite my using European sunscreen or IT CCcream religiously. Reading about vitamin C from the lovely skincare board ladies, and youtube videos like Uppiesbeads59 (who also provides a handy mixing chart), I ordered vit C powder from Garden of Wisdom, and went to town mixing it up with rose water and glycerin. Started using it nightly about a year and a half ago. After about 6 months, the NC25 was looking a bit dark, but still doable. Then, excited at my progress, I plunged into Japanese sunscreens last summer. Also courtesy of the skin care board sages. So for the past year I've used the vit C and either Biore or IT CC on any given day. This spring I pulled out the old MAC NC20, and it looked a much better fit than the NC25. Just a few weeks ago, and this is summer, mind you, I took a gamble on a very old NC15 compact. And, yeah, it looks just fine. The NC25 (and other foundations similar in color) that matched me just 2 years ago now look so dark. So, yeah, combo of better sunscreen and - equally important- the vit C serum is turning back the clock on my sun damage. And another bonus: it's wonderfully inexpensive to make, as well. I may not be 25. I may not look 25. But at least my skin color is 25 again!

My rating is really for the Paula's Choice Vitamin C15 booster. I have very sensitive skin; the DIY versions of this are just too irritating for me, I even have to be cautious with the PC one. But she has sales all the time, and you can get a trial (not just a one time sample) size to give it a go. A full size bottle lasts me a year or so.

The first time I did this, I put the vitamin c powder in my hand and mixed it with tap water. The powder didn't dissolve but I still rubbed it onto my face. The next morning, my skin felt softer. I then made a 5% solution and placed it in a vial and shook it. This time the powder dissolved. It has been 2 days since I've been using the diy serum (more of a toner for me since I only use water) and my face feels softer with less rough patches and it seemed less oily. I purchased the vitamin shoppe brand of the vitamin c powder at their store. $10 for 8 oz jar.

I started making my own Vitamin C serum in January 2015, after reading the famous Reddit thread.I bought some crystalline LAA powder (food supplement) and glycerin online, as well as some violet glass spray bottles. I have a kitchen scale that's sensitive to +/- 1g so I do my measurements by weight.I make a batch every week or so and keep it in a cupboard at RT. I use it copiously every morning on my face, neck, décolleté, hands and upper arms. I feel it has made a noticeable improvement to my skin, both in the short term (it definitely brightens skin tone, immediately) and in the long term (fine line reduction, general vibrancy/suppleness)The one tiny tiny downside is, I sometimes get the occasional whitehead on my nose (and only on my nose). I pop it, it disappears, and it seems to heal immediately. No harm, no foul. However lately I've been leaving the glycerin out, and it seems to reduce the whitehead appearance frequency, so my new formulation is 20% LAA, 80% distilled water and 0% glycerin.I use it in the morning after splashing my face with water, and before applying moisturizer with SPF. I found using it at night leaves brown traces on my pillowcases (like oxidized apple slices - comes out in the wash, but still...) so I switched to using it in the morning, problem solved.The spray bottles clog with Vit C, so I would recommend a dropper bottle or just a normal cap - I pour the serum out into my palm and dab/rub it on, no dropper or sprayer needed.Long story short, it takes almost no time at all to mix up a batch, just a minute in the morning to apply it, and it has excellent results. And it's cheap as chips... I wish other solutions in my life were so easy! :)

I make this serum at the start of every week and it lasts for 3-5 days max in the fridge, in an amber glass bottle which stops UV sun rays from damaging the vitamin c (vitamin c is very unstable once it is mixed with water, keeping it for longer will mean it won't work and can cause damage to skin cells) but it is well worth it. Vitamin C contributes to the production of collagen in the skin, and its acidic nature helps remove scars, even skin, and remove discolouration. Ever since I have started using this serum, I have not had any new spots, my dark circles under my eyes are barely noticeable, and my skin is smoother, plumper and looks the best I have seen it in a long time. After the first night of using this I saw results instantly and have been receiving compliments about how nice my skin looks now. I use one level teaspoon of vitamin c (not heaped) with 8-10 teaspoons of water (9 teaspoons will make a 10% formula of vitamin c, its best not to use a percentage higher than 20% which would be 4 teaspoons of water), it is important not to use too much vitamin c or else you could burn skin with the acid, when done correctly its completely fine so dont worry lol, you can purchase litmus paper to check the acid levels if you have concerns. I hope more people try this as it is a brilliant skin treatment.

Weighing in on the boiling water situation, the Internet is a wonderful place. The melting temp of vitamin c is 190 degrees. Anything short of that will not destroy or destabilize or whatever other term people are using. If you are wondering how hot 190 degrees is, 190 is insufficient to brew a good cup of espresso though it is okay to make tea. If you can stick your finger in the water, it is not too hot to dissolve your vitamin c powder into. Hth!Regarding yellow or brown, if it encounters 2 electrons, it turns into something else and starts to decay. The darker your solution, the higher the percent of your solution is no longer active vitamin c. Yes you can use it. No it's not as effective. It is, technically, just a lower percentage now. The darker it gets, the lower he percentage. Darkening is caused by light and air. Best way is to store small amounts in dark places. Open a new vial when you run out of the old. If you buy a commercial form, do the same thing to keep it active longer. Return right away if it's yellow or brown. It means that it's less effective than what you think you are paying for. Decant into smaller bottles and seal tightly. Wrap your bottles in tin foil to block out light. More effective than either cobolt blue or Amber glass. It's what labs do. Cold storage also slows down the decay. Fridge is fine.

I buy the least expensive food grade 100% pure ascorbic acid (= vitamin-C) on any internet shop in as large amount possible without beeing to expensive to ship and not over VAT and import penalty.I use it as a natural chemical peel every 3 - 4 weeks and it works wonder and needless to say not even near the expensive and invasive chemical peels in any other comercial businesses. (Synthetic vitamin-C is made from sugar and exactly the same molecule as naturally extracted vitamin-C). Start with about 5% until skin is used to the acidic solution. Now I am using about 1/3 ascorbic acid and 2/3 warm (NOT above 39 C° - 102° F to not oxidize the vitamin-C) mineral (steril) water to a total of 3 cl. I do not use glycerin for enhancing the peeling effect.First I use a very hydrating/moisturizing serum and mask to maximize skin penetration. After washing it thoroughly of and pat dry skin i use a thick but not to broad brush to carefully apply it to my face and neck. (It stings like h*** if you lett any droplets run into your eyes of course).To get the benefit without any downtime of the peeling as well as collagen stimulating effect you need to get the skin really acidic (which stings but is not painful). After the first very thin layer the ascorbic acid will crystalize on your skin when drying (about 2 mins). For each layer the crystals will able you to have a little more ascorbic acid on your brush. When my skin is almost completly white with tiny crystals I lay down and spray with sterile still mineral water several times each time my skin dryes over.Blacheds gone and pores actually reduces in size after a couple of years with the benefit of a mild deep peeling (bye lines and wrinkles) and heavy collagen stimulating effect. Without glycerin no sticky feeling and max penetration. Use a calming moisturizer after without wiping the ascorbic acid of and a heavy cream or oil and do this before bedtime. Use SPF as usual in the morning.Use your daily vitamin-C serum as usual for daily antioxidant if you like. Just remeber when your DIY serum turns yellow/orange and sticky the vitamin-C is oxidized and do nothing for your skin any more.
