The Skincare Guide: Vitamin C

If you have been following me for a while, you probably already know about my addiction to skincare products; witnessing me always testing new things and getting excited for new launches. It’s been like this for years, and eventually you just get sucked in by the skincare universe, without realizing people don’t have the same insane passion for it. Even if you are not a skincare fanatic like myself, you probably still want to know if a product works.

I realized this when I approached my friends with questions along the lines of: “Hey I’m testing a new acid toner, do you see any difference on my skin already?” and they looked at me horrified, as if I’m actually using some sort of poisonous acid to dissolve the surface of my face. 

To avoid this confusion, I’ll be making short blog pots about the most common skin care ingredients, the benefits, if I tried them and of course if I liked them.

What does “active ingredient” mean?

An active ingredient, is the ingredient in a product addressing whatever skin concern it’s meant to target.

You will hear the word active quite frequently when people talk about skincare products and why this particular agent works for “this” or “that” concern.

Don’t worry, names can sometimes sound scary, but hopefully this posts will familiarize you with the most common ones.

Your daily skin protection: Antioxidants

In the same way that consuming antioxidant-rich foods aids your body in fighting off free radicals, topical antioxidants do the same for your skin by helping to offset daily aggressors like UV damage or exposure to air pollution.

Vitamin C is a common antioxidant, especially when we talk about day time serums. These serums act as a barrier to protect your skin all day long and they do an excellent work at it. Vitamin C plays a vital role in skin health by stimulating reactions resulting in collagen production. 

Use vitamin C if you’re looking to improve uneven skin tone, rough texture, fine lines, acne scars, and general dullness (especially this). I’ve seen particularly amazing results when it comes to providing radiance and smooth texture to my skin.

My favorite so far is La Roche Posay Pure Vitamin C10 . I use It every morning, the price is  decent and widely available everywhere. Another favorite is the “Truth Serum” by Ole Henriksen, which sadly is not available at Sephora Switzerland yet.

You’ll also notice that Vitamin C serum bottles are dark, and that’s on purpose. As soon as the product is opened, it’s active in the bottle and the compounds begin to change. You’ll realize after a couple of weeks that the serum will turn brownish or at least a darker color (at the beginning it has a light yellow color). 

This happens because it has oxidized (reacted with oxygen). The yellow-brown color change, is a visual sign of chemistry change. While the oxidization of Vitamin C can’t be stopped, it can be slowed down through limiting its exposure to heat, light and air. 

Yes, when your serum gets to this stage it will be less effective. Some people suggest to keep your vitamin C products in the fridge, I haven’t personally tried this but why not?

The life span of La Roche Posay “Pure Vitamin C10” is 2 months. This means that if you buy it, you must use it! 

You can’t forget it at the back of your counter for months and expect it to work if you use it again. Good news, two months is enough to finish 30 ml with pretty looking skin.

I like to see this serum as a cure, I know I have to stick to it every morning and it pairs well with any other skincare product from my routine! When you apply it, it has a goopy gel-like texture, but that goes away as the product sinks into the skin, with this particular product you will start noticing visible results after a week of daily use.

Of course vitamin C can be found in many other skincare formulations and textures, for example as a loose powder (water free)* to be mixed with your cleanser or with your hydrating cream, as a serum with a cream texture (also water free)*, or a silicone texture serum.

*water free, means that the formula don’t contain water and therefore the process of oxydation won’t take place.

All these different presentations of vitamin C have been created to stabilize the active ingredients, and make them last longer without losing its properties. Even though I understand the principle and they do last longer, and they also provide good results, I still prefer the La Roche Posay’s serum, because I like the sensation of liquid products against my skin.

Whether you prefer a water based formulation, or a water free it’s really just a matter of personal preference, I highly suggest to give them a go, and see which one works best for you!

There are so many options of vitamin C products on the market and I haven’t had the chance to test them all of course, but I’m super interested in testing Summer Friday’sCC Me serum” and the Pure Vitamin C 21.5% Advanced serum” by Wishtrend thanks to their positive reviews online.
