Vitamin C and its derivatives in skincare – everything you need to know!

Vitamin C, also known as L-ascorbic acid, is an awesome ingredient for skincare. It’s one of those ingredients that actually has the data to back up the claims. Vitamin C is an amazing antioxidant, protecting the skin from damage done by UV-light or pollution. It also affects collagen synthesis, and as we know, collagen together with elastin are what keep our skin plump. If that is not enough, it has skin lightening effects, helping to fight melasma. It’s even been said to have anti-inflammatory properties.

 

I study chemistry of cosmetics and that includes taking a deep dive into ingredients and how they really work on the skin. Recently I did research on Vitamin C and it opened my eyes to the complexity of active ingredients. You see, a great ingredient is not enough. Your skin needs to also be able to use it! That’s kind of the deal with vitamin C here – and why most of the serums and creams use vitamin C derivatives.

L-ascorbic acid also known as Vitamin C  in skincare

Vitamin C is a an essential nutrient and it occurs naturally in the skin. However, being exposed to UV-light, the amount of Vitamin C in the skin diminishes drastically. Using vitamin C in skincare can have many benefits.

Vitamin C’s benefits in a nutshell:

Powerful antioxidant

  • protects skin from damage caused by UV light or pollution
  • helps your skin in a way to protect from UV damage and reverses damage (but is not SPF)

Affects collagen synthesis

  • actually the only ingredient proven to do this. Interestingly many collagen supplements are sold with this claim – but the claim is about Vitamin C, not collagen
  • collagen together with elastin make your skin plump and youthful – as your skin forms less of these, wrinkles start to form

 

Anti-inflammatory & depigmenting properties

  • there are some studies showing anti-inflammatory properties of Vitamin C in treating acne
  • it also helps to fight hyperpigmentation and melasma. There are studies of Vitamin C derivatives also being able to lighten the skin

So all in all, it’s an ingredient that works with pretty much all skin types.

Vitamin C derivatives – what’s the deal with them & what works best?

Vitamin C is awesome, but pure L-ascorbic acid is a tough ingredient to work with. It’s unstable and because it’s hydrophilic (and works best in acidic solutions), it penetrates the skin poorly. That’s why most beauty products use vitamin C derivatives. These derivatives are stable and can come with different solutions to absorb to your skin better.

You’ll spot these derivatives from the ingredients by “ascorbyl” or “ascorbate” -something.

Obviously most of the high claims and benefits are for pure L-ascorbic acid. And in order for you to get the benefits – the ingredient needs to transform into L-ascorbic acid on your skin. Luckily there’s promising studies on some of these derivatives doing so! (Such as Magnesium Ascorbyl Phospate, Sodium Ascorbyl Phospate, Ascorbyl Palmitate and Ascorbyl Glucoside.)

How to choose the best Vitamin C product in skincare

If you want to use pure L-ascorbic acid, make sure it’s high enough concentration (10-20%). You should also pay attention to the packaging: is it made so that the ingredients (vitamin C most importantly) are preserved? Preferably not a pipette, but something that closes tightly. The product should also have a lower pH – 3,5 to be precise. (I’m not sure if that happens with most products and if it does, it can cause irritation.) Other ingredients can be added to the product to make it blend or absorb to the skin better. The Ordinary’s silicone based creams are an example of this.

As to the vitamin C derivatives, those should also be 10-20%. I accept a higher procent too, since it is a derivative. I like the fat-soluble ones. Those are more likely to be accepted by our skin, so I trust their penetration better.

Both the oil and water-soluble derivatives are stable, so packaging can be a pipette too (like in the photos).

The best product for you can only be found by trying!

Finally I want to note, that it’s different testing something at the lab, than using a lotion at home. It’s difficult to say for sure if a product is gonna work or not. As to the absorption of the vitamin C and its benefits – I guess it’s just about trying it out and hoping for the best. My logic is, that since I’m anyway taking good care of my skin, why not use vitamin C if there is even a small chance of improving my skin even further?

 

Product recommendations:

*The Ordinary Tetraisopalmitate Solution 20% (Lyko.fi)
Contains oil-soluble Vitamin C derivative.
Really lightweight serum, that also has squalane in it, which is an awesome ingredient in skincare. It’s similar to squalene, found in sebum, which is a part of the protective layer of the skin.

*The Ordinary Ascorbyl Glucoside Solution 12% Serum (Sephora)

*The Ordinary Ascorbyl Glucoside Solution 12% Serum (Lyko.fi)
Water-soluble Vitamin C derivative serum.

*The Ordinary Vitamin C in suspension 23% (Sephora)
*The Ordinary  Vitamin C in Suspension 23-30% (Kicks.fi)

7th heaven Vitamin C Capsule Concentrates
A good example of air-tight packaging that protects the active ingredient from oxidizing! However, I don’t know the pH or the % of ascorbic acid, so I can’t really recommend them yet.

 

I’ll update this list as I try new ones. Feel free to share your experience on the comments! Also, if you have any questions, I’m here.

Lumene Natural Glow Foundation – honest review

Lumene’s Natural Glow Foundation is one of their most popular products and for a good reason: it’s an affordable foundation that evens out the complexion leaving – as promised – a beautiful glow on the face.

I love foundations, but I’m quite picky on them. Several boxes need to be checked for me for them to make it on my beauty blog. However, I have reached for Lumene’s foundation so many times now, I have to admit: I do love this foundation. I’m a busy bee nowadays and my makeup needs to happen fast. This I can just apply with my fingers so it saves me time and effort.

Lumene Natural Glow Foundation review

Lumene is a Finnish brand that all Finns know. I would think most women at least have used a product from them. It’s funny, but I feel a sense of pride every time I see Lumene mentioned in a review or in a video abroad.

Three out of four makeup customers of mine bring a bottle of Lumene foundation with them. Several of my friends have said they wear this particular foundation. To be perfectly honest – for me it wasn’t love at first sight with this foundation. I’m pretty sure my skincare products at the time didn’t mix that well with some ingredients, because I couldn’t make it work. But then one day I tried it again and I was amazed.

And now I use it too.

Natural-looking foundation, that gives glow

What I like most about this foundation is the gorgeous packaging, easy-to-apply consistency and a natural look and feel on the skin. Most of the time I apply it with my fingers, but it also works with a beautyblender. Brush I rarely use, just out of habit.

The foundation evens out my complexion by hiding small imperfections or redness – yet it’s glowy and light enough so that my skin still looks like my skin. The texture is smooth, creamy and buildable. Though I don’t think you need that much product, because a little goes a long way with this one.

My shade is 1.5 fair, which I would describe as quite neutral. It has more red than most of my foundations, but not so much I can’t use it. Usually I prefer yellow-based shades, because those disappear into my skin best.

As to the longevity, I think this foundation performs just fine. It lasts a regular day with me. At the end of the day I might shine a little bit more, but there’s powder for that. Anyway, I’ve always thought that foundation can and should live a little on the skin. That’s also why I prefer natural-looking foundations – it looks great even if it wears out a bit. With a full coverage matte foundation however – you notice easier if it starts to wear off.

All in all, a lovely foundation

The only minor aspect I would change on the product is its scent. It’s not particularly strong, nor unpleasant, but it’s something I notice. I should mention, though, that I rarely use perfumes. Most of my skincare products are either unscented or have natural scents that evaporate quickly, so I’m more accustomed to those. Nevertheless, I continue to use this foundation because it’s great. Plus, its application is just as swift on my skin as tinted moisturizers, which I happen to adore as well.

But since I’m on the subject of perfumes and scents. In a perfect world, everything would just smell like vanilla. I love vanilla.
