It is one of our first concerns for wrinkles and soft skin. Indeed, we are more than 62% to curse our brown spots and try to wipe them. Good news: formulas have evolved and specialists offer us very effective assets today.

They are part of the bad memories of vacation ... but not only: brown spots are definitely often sun lentigo but can also be caused by some estrogen treatments (pill, menopause treatments), drugs (antidepressants, antibiotics, anti-inflammatory drugs) , diuretics), pregnancy or simply aging of the skin.

Removing it, or even blurring it, may be a real obstacle course.

Fortunately, there are effective treatments and assets to prevent the appearance of new spots and to wipe those already present.

Anti-tyrosinase

To make it simple, tyrosinase, an enzyme involved in making melanin, may sometimes be diligent and anarchic. A dysfunction that is responsible for the appearance of known sites.

Thus, Bates was developed to reduce production.

Hydroquinone:

This chemical molecule, known since the 1960s, is so "terrible" effective to cause irreversible depigmentation. It is therefore forbidden in cosmetics and only dermatologists can use it.

Arbutin:

Extraction of beard leaf, a shrub growing in regions around the polar circle, effectively inhibits the activity of tyrosinase and helps melanin break down (and thus eliminate faster).

It is often associated with vitamin C, PP or Glycyrrhetic acid (extracted from Lekkerwortel), a good anti-inflammatory to improve its effectiveness at a lower dose.

Cooking acid:

derived from fungal form, which is called a chelator, an active agent that blocks two copper atoms in the tyrosinase, preventing it from doing its work.

Attention:

It may be a little annoying because it should be effective. It must be associated with formulas with glycolic acid, aberrant.

Dioic acid:

it acts on one of the genes tyrosinase. It not only prevents it from acting, but also reduces the spread of melanin to the stratum corneum and thus its accumulation in pigment spots.

Glabridin :

This extract (Lekker), a plant known for its flash effects, inhibits melanogenesis.

In addition, a new nutritional supplement based on SOD (superoxide dismutase), an extract of melon associated with borage, lycopene (tomato extract) and hesperidine (bitter orange extract) have recently been proven, studies to support anti-blotch performance are a lot Except for the second month of use (Radiance of the skin, Glisodin, Laboratory Isocell).

Vitamin C:

It is one of the best free radical abrasives (which simultaneously regulates the diligence of melanocytes). Be careful, it may be a bit annoying if its PH is acidic, so its importance to associate it with anti-inflammatory active ingredients.

Vitamin E or tocopherol:

From oils and oleagins, it works in synergy with vitamin C, beta-carotene and selenium by cell membranes.

Polyphenols:

present in plants, especially fruits and vegetables, these micronutrients have very effective antioxidant forces.

exfoliants

They accelerate the renewal of cells to chase brown keratinosites and give better penetration of depigmentants.

The latter contains for the most part

alpha-hydroxy acids,

better known as AHA. Made of fruit sugars (glycolic acid), milk, (lactic) apples, lemon juice, grapes, these soft exfoliating active ingredients also have the ability to stimulate the synthesis of collagen, elastin and reduce pigmental stains.

Aselaic acid,

composed of grains (wheat, barley, rye ...) has the advantage that it is slightly keratolytic (it removes the keratin layer from the skin and eliminates it as well as antibacteria. To recommend acne skin.
