Why do we need an antioxidant?

This is the question that comes up very often: "Why apply an antioxidant face serum when I have been without it for years?" Our skin naturally defends itself against external aggressions by intercepting free radicals, responsible for the aging of the skin. But its defense capital is not unlimited and often needs help to be optimal.

You will tell us that a varied and balanced diet can be enough to provide the necessary dose of antioxidants for the skin. 

While our body needs to have a supply of antioxidants through the daily consumption of fruits and vegetables, only ⅓ of the antioxidants that we ingest go to the skin. This is why a supply of topical antioxidants is essential to prevent skin damage and visibly correct the signs of aging and hyperpigmentation.

How does vitamin C serum get into the skin?

Topical vitamin C is a basic unstable antioxidant. For it to penetrate the skin and thus neutralize free radicals, it requires strict formulation parameters. 

Serum must contain a concentration of pure vitamin C serum between 10% to 20% max, and be integrated into an acidic formulation with a pH lower than 3.5 so that it can penetrate in to the skin to effectively protect it from damage. Caused by the environment.

Why do we have serum-containing several antioxidants?

It is possible to combine several antioxidants in a single serum to provide more complete protection. For example, Derma Essentia's Vitamin C Serum is combined with hyaluronic acid to provide increased protection against free radicals, improve skin firmness, reduce the appearance of wrinkles and fine lines and brighten the complexion.

This specific combination must of course be clinically validated for its effectiveness and synergy to be guaranteed because an unoptimized mixture of antioxidants can cause instability of the formula or even a negative effect.

Is vitamin c serum compatible with the sun?

You can use vitamin C serum when the sun is shining since it can be used all year round, summer and winter. It is also essential to apply protection adapted to your skin type at the end of your face care routine. 

Indeed, the anti-free radical action of vitamin C complements the protective action of protection, increasing its power by approximately 30%. 

This is why we advise you to use a sun filter after applying your vitamin C serum because these two products combined have a real shielding effect on your skin.

Can vitamin c serum be applied to all skin types?

Yes, it is possible to apply a vitamin C serum to all skin types as long as you choose the right serum, of course! For example, oily skin will opt for an antioxidant serum containing active ingredients that act at the same time to reduce excess sebum, such as Derma Essentia's Vitamin C Serum. 

Sensitive and dry skin, for its part, will opt for a serum that incorporates soothing and lipid-replenishing agents, to reconstitute the fat reserves of the hydrolipidic film.

Is vitamin c compatible with another active ingredient?

Vitamin C complements perfectly with other active ingredients, such as Hyaluronic Acid or Niacinamide.

However, avoid incorporating a vitamin C serum in facial care routines including AHA / BHA (including the famous glycolic acid), salicylic acid, Retinol, copper peptides, or even benzoyl peroxide. 

In these cases, the association of vitamin C with these assets will either cause irritation and flaking or cancel the effects of the assets in question.

Does a highly concentrated vitamin C serum systematically cause irritation?

A too high concentration of vitamin C can cause skin irritations such as tightness, stinging, and discomfort, especially on sensitive skin. That's why it's important to choose the right vitamin C serum for your skin type.

Does vitamin c cause pimples?

A vitamin C serum can be irritating to sensitive and reactive skin but does not cause pimples.

How often to apply vitamin c serum on face?

In your daily beauty routine, morning and evening. Be careful because too much is the enemy of good. 

In high doses, vitamin C can become pro-oxidant and therefore have the opposite effect of what you are looking for. 1 to 2 times a day is, therefore, more than enough.
