Cosmetic active ingredients: everything about their dosage and concentration

Cosmetic active ingredients must be precisely dosed and concentrated
Active ingredients play a central role in the effectiveness of cosmetic products. However, simply including these ingredients in a formulation is not enough to guarantee optimal results. The dosage and concentration of each active ingredient are essential to ensure both the effectiveness and safety of the products. In this article, we explain their importance and highlight some concrete examples of ideal concentrations for certain common active ingredients.

The essentials on active ingredient dosage and concentration

  • Active ingredients are chosen for their specific effects on the skin, such as hydration, firmness, and reduction of the signs of aging.

  • A high concentration does not always mean increased effectiveness.

  • The synergy of ingredients and the overall formulation are crucial.

  • It is important to choose skincare products whose active ingredients are scientifically dosed and adapted to your skin type.

Understanding Cosmetic Active Ingredients and Their Role

The active ingredients (also known as ingredients) in a cosmetic product are the compounds that exert a specific action on the skin. They can be ofnatural and plant-based or synthetic origin. Among the most commonly used are moisturizers such as hyaluronic acid, vitamins such as vitamin C, or exfoliating agents such as fruit acids (AHAs).

Cosmetic ingredients arechosen based on their ability to act on specific skin issues and factors. For example, they are used to:

  • Nourish dry skin.

  • Restore firmness to the skin.

  • Reduce the visible signs of aging.

  • Reduce expression lines.

  • Etc.

However, the mere presence of these active ingredients in a product is not enough. Their effectiveness depends largely on their concentration and the design of the formula into which they are incorporated.

The Importance of Dosage

It's a common misconception that the higher the concentration of an active ingredient, the more effective the product will be. However, this idea is misleading. For two reasons:

  • In a treatment,an active ingredient never acts alone. There must be synergy between the ingredients, and too much or too little of a certain active ingredient can inhibit or "disrupt" the action of other active ingredients.

  • As in many other areas,it's the dose that makes the poison. This means that above a certain concentration, an active ingredient could prove counterproductive, ineffective, or even cause irritation. Rest assured, our experts are familiar with all these parameters and have long known how to create skincare products with optimal tolerance for our consumers' skin.

The example of botulinum toxin, popular in aesthetic medicine to reduce wrinkles, perfectly illustrates this concept. In high doses, it is one of the most deadly plant poisons, but in low doses, it is safely used to treat expression lines.

Therefore, when reading a product's ingredient list, it is crucial not to rely solely on the concentration of its active ingredients to judge its effectiveness. The overall formulation, pH, and synergy between the different ingredients also play a key role.

Some practical cases and examples of active ingredient concentrations

Vitamin C

Vitamin C (whose scientific name is ascorbic acid) is known for its antioxidant and skin-lightening properties. It helps neutralize free radicals, reduce signs of aging, and even out skin tone.

However, at too high concentrations (from 10% to 20%), it can become irritating to the skin, especially when combined with other acids.

Peptides

peptides are highly prized in anti-aging skincare, among other things for their ability to stimulate collagen production and fight premature skin aging. Although they are used in very low concentrations (around 0.01%), their effectiveness is nonetheless remarkable.


Fruit Acids (AHA)

Fruit acids, or AHAs (Alpha Hydroxy Acids), are used in cosmetics for their ability to gently exfoliate the skin. They help remove dead skin cells, improve cell renewal, and brighten the complexion.

They are effective at varying concentrations (from 5% to 20%) in daily skincare. Higher concentrations are reserved for salon treatments under professional supervision. In both cases, there is a risk of irritation and increased sensitivity to the sun. Therefore, avoid applying them in summer and use them as directed on their packaging.


Hyaluronic Acid

A moisturizing product containing hyaluronic acid will be effective even at low concentrations, as this active ingredient has the ability to absorb a large amount of water, allowing it to deeply hydrate even at low doses.

The importance of choosing the right concentration for optimal effectiveness

The concentration of cosmetic active ingredients is therefore a crucial element to consider when choosing your skincare products. Since a high concentration does not always mean greater effectiveness, and can sometimes even lead to unwanted side effects, it is essential to choose optimally formulated products based on a solid scientific basis and rigorous clinical studies, tailored to your skin type and needs.
