You probably already know that when it comes to skincare, there is not a single ingredient that is magical, regardless of its price or the fact that it is rare to find.
Like eating only one type of vegetable can’t give your body everything it needs, a single ingredient, regardless of its effectiveness, cannot give your skin everything it needs.
Yet, when we look at cosmetics advertisements we note that vitamin C is present everywhere and it claims the merits as if it were a miracle ingredient.
My advice: rather than blindly believe all those ads with great buzz words marketing, it is preferable to rely on scientific research, because they give us facts.
Around 20 years ago, it has been demonstrated how a form of vitamin C, known as L-Ascorbic acid, reduces UVB damage when applied to the skin.
It has been suggested that sun damaged skin could be repaired using topical vitamin C.
Vitamin C is widely used in cosmetics and it can be confusing because there are many forms present in varying concentrations.
So here is what you must know about vitamin C.
Forms and effective concentrations of vitamin C.
You must seek the following forms in the list of ingredients, because they have been proved to be the most stable and the most effective:
- Ascorbic acid
- L-Ascorbic acid
- Ascorbyl tetraisopalmitate
- Sodium ascorbyl phosphate
- Magnesium ascorbyl phosphate
- Tetrahexyldecyl ascorbate
and the level of the concentration must be between 5% and 10% to be really effective.
Very few companies indicate the concentration of their vitamin C, but for the product to be effective, it should be at the beginning of the list of ingredients, at most in the middle.
In addition, all antioxidants, like vitamin C, are vulnerable to degradation in the presence of light and air. If a product containing antioxidants is not in an opaque bottle, which lets through light or air, you shouldn’t buy it.
What does Vitamin C do?
- Protects skin’s cells from UV rays damage
- Improves sun damaged skin
- Makes skin more resistant by strengthening its natural protection barrier
- Reduces inflammation
- Stimulates collagen synthesis
- Reduces hyperpigmentation (brown spots)
Vitamin C is therefore an essential part of your daily skincare routine!!
