The best vitamin C serum is on that is stable, non-sensitizing and also effective on all skin types.
How do we choose the best vitamin C serum formulation recommended by dermatologists? We go into the dermatological science behind identifying the best formulation of what is probably the best known antioxidant, it’s benefits to skin and how it actually works.
Dermatologist Dr.TWL shares that the benefits of Vitamin C serum for face are manifold. For example, it’s potent antioxidant properties protect skin from oxidative damage (anti-wrinkle) and combats oxidation of sebum which clogs pores (anti-acne). These benefits are magnified in an ideal Vitamin C serum formulation.
According to the dermatologist, the best Vitamin C serum is formulated according to some key principles:
• Does not degrade easily
• Remains stable when exposed to the environment
• Effective & gentle on all skin types including sensitive skin
Being a very potent antioxidant, raw Vitamin C or L-Ascorbic Acid reacts rapidly with oxygen and gets oxidised under room conditions. This often results in L-Ascorbic Acid based Vitamin C serums having to be formulated with higher concentrations. For example, 20% L-Ascorbic Acid formulations may quite frequently be marketed. Whilst the double digits may sound impressive, it is actually in order for the Vitamin C serum to survive the degradation in some manner and have any reasonable efficacy by the time the molecule is absorbed by the epidermis and dermis. This is not optimal.
A consequence of high concentrations of L-Ascorbic Acid, however, is that, as may be suggested by the chemical nomenclature, it increases acidity on the skin. For individuals with sensitive skin or eczema-prone skin, it is not uncommon for dermatologists to see patients who experience irritation and flare ups following the use of such highly concentrated L-Ascorbic Acid Vitamin C serum formulations. The best Vitamin C serum formulation as such needs to overcome this inherent limitation with raw Vitamin C or ascorbic acid.
