Here are 5 vitamins that our little jars often contain.
Its action on the skin
“Also known as retinol, vitamin A has long proven itself in the cosmetics industry,” begins the international trainer for the Quebec brand IDC, Nancy Labonté.
“It is certainly the vitamin best known for its effectiveness, supported by clinical studies.” Reduction of wrinkles – even deep ones – and fine lines, protection once morest free radicals, stimulation of elastin, reduction of pigment spots, treatment of acne: retinol does it all! No wonder, therefore, that we find vitamin A in anti-wrinkle creams as well as in illuminating treatments or formulas intended to even out the complexion.
Too good to be true? “This vitamin gives truly extraordinary results, but it often causes irritation and redness,” recalls Nancy Labonté. It’s a beautiful molecule. To date, it is the most tested ingredient. While its effectiveness has been proven time and time once more, it is also the vitamin least well tolerated by the skin.”
Not to mention that it is a notorious photosensitizer. We should therefore avoid exposing ourselves to the sun when using it. “This is why most companies prefer to only put it in their night creams,” she adds.
To minimize the skin reactions that creams or serums containing retinol can cause, we proceed gradually. Nancy Labonté, for example, suggests getting our skin used to the product by applying it every other evening, or even once or twice a week, to start. We reduce irritation by, for example, using a rich, moisturizing cream to layer on top of our retinol serum.

Orange vegetables and fruits, such as carrots, sweet potatoes and pumpkin, as well as leafy green vegetables, are excellent sources of vitamin A. While consuming these foods does not in itself constitute a health cure, rejuvenation, they remain essential in order to preserve the health of several organs, not only the skin, but also the eyes, reveals Marie-Ève Labonté, assistant professor at the School of Nutrition at Laval University.
Good to know
Vitamin A makes our skin more sensitive to the sun. When you take a retinol treatment, you therefore take care to apply sun protection once morest UVA and UVB (SPF 50+) every morning, rain or shine. If you spend the day outside, reapply every two hours.
Its action on the skin
Most often called niacinamide on our bottles – and not to be confused with niacin, another form of B3 – this vitamin is attracting more and more attention, and for good reason: “It restores the barrier function of the skin , soothes redness and fades spots while giving radiance to the complexion.
It helps regulate sebum production and acts as an anti-inflammatory, which helps reduce acne and accelerate healing,” says Nancy Labonté. And that’s not all: its anti-aging and hydrating properties have been widely documented.
According to the active ingredient expert at IDC, the awareness of niacinamide is therefore expected to continue to rise. “Vitamin B3 should have become popular a long time ago. It offers as many benefits as other vitamins and has few adverse effects, since it is very well tolerated, even by sensitive skin. I don’t think that retinol will lose its place, due to its unrivaled effectiveness, but I predict that we will soon be talking regarding vitamin B3 as much as vitamin C, the other star of the hour in terms of ingredients cosmetics.

In order not to lack vitamin B3 in our diet, we just need to consume various sources of protein, whether plant or animal. “Meat, poultry, fish, milk, eggs, legumes and nuts are the best sources of vitamin B3,” summarizes nutrition professor Marie-Ève Labonté. Whole grain cereal products also contain it.
Its action on the skin
Well known for its restorative effect on the skin, hair and nails, vitamin B5, panthenol by its nickname, is also renowned for correcting dehydration problems by fighting once morest water loss. “Vitamin B5 is a little different from other vitamins, because it does not offer anti-wrinkle or anti-aging benefits,” emphasizes Nancy Labonté. Applied locally, panthenol visibly improves the hydration of the stratum corneum, the surface layer of the skin.
This favorite ingredient in anti-redness treatments also has excellent healing properties, since it stimulates cell renewal. No wonder many following-sun restorative treatments are full of it!

“Vitamin B5 is very widespread in our diet,” indicates Marie-Ève Labonté. Thus, a balanced plate containing a good source of protein (meat, fish, dairy), cereals, without forgetting abundant fruits and vegetables – plants should cover regarding half of our plate, she argues – will satisfy our needs. needs.
Its action on the skin
Used for decades in skin care, vitamin C is still among the most popular cosmetic ingredients on the market today, particularly because of its tested and approved anti-aging benefits. How does she act? Particularly rich in antioxidants, vitamin C neutralizes free radicals produced, among other things, by UV rays, stress and pollution, the cause of premature aging.
Beyond its anti-wrinkle effect, vitamin C brightens the complexion thanks to its targeted action on melanocytes, the cells responsible for skin pigmentation. “Vitamin C has a lightening effect,” summarizes Nancy Labonté. It reduces pigment spots, evens out the complexion and reveals its radiance, regardless of our skin type.” It’s not complicated, it’s perfect for giving us a peachy complexion!

According to Marie-Ève Labonté, broccoli and Brussels sprouts are two of the best sources of vitamin C, as are many green vegetables. Orange fruits and vegetables, especially red, yellow and orange peppers, are also full of it.
Its action on the skin
An old grandmother’s trick is to apply the contents of a vitamin E capsule to our dry skin, in order to deeply nourish it. This is not trivial: vitamin E, “very nutritious and hydrating”, is the emollient ingredient par excellence, confirms Nancy Labonté. Moreover, it is the natural ally of creams with an ultra-rich texture. “Vitamin E also has antioxidant and anti-wrinkle properties, but we know it more for its ability to soften the skin, nourish it and reduce redness.”
An active ingredient that is also suitable for the most fragile atopic skin: “We obtain very good results in the treatment of dermatitis or eczema, because this vitamin also has anti-inflammatory, healing and calming properties.”

Vitamin E deficiencies are rare in our industrialized countries, notes Marie-Ève Labonté. “This is also the case for all the vitamins mentioned above,” she explains. The typical example of a plate full of vitamin E? A meal salad made with leafy green vegetables, nuts and whole grains, topped with a vegetable oil-based vinaigrette.
