The world of cosmetics: discovering the active ingredients


The universe of beauty is a wide and fascinating landscape, where the choice of cosmetics becomes a form of personal expression and care for oneself. At the heart of this experience are the “active ingredients”, the real protagonists of cosmetic products, capable of transforming the skin and giving brightness and vitality.

Immersing yourself in the world of active ingredients is like opening a book of secrets, where every ingredient reveals a unique story on our skin. In this article, we will accompany you on a journey of discovery, explaining what are the active ingredients, what are the most common and how to identify them in the INCI.

What are the active ingredients

The active ingredients in cosmetics play a key role in promoting the health and beauty of the skin. These active ingredients are carefully selected for their beneficial properties and their ability to interact positively with the skin. First, they act at the cellular level, penetrating the surface layers to facilitate the renewal and regeneration of skin cells. Some active ingredients are known for their ability to hydrate in depth, keeping the skin soft and elastic.

In addition, many cosmetics contain powerful antioxidants, such as vitamin C and hyaluronic acid, that fight free radicals responsible for skin aging. These ingredients help protect the skin from environmental damage, reducing the appearance of wrinkles and thin lines. Other active ingredients, such as exfoliating acids, help remove dead cells from the skin surface, stimulating collagen production and improving overall texture.

What are the most common active ingredients

Alpha-hydroxy acids (AHA)

AHA, such as glycolic acid and lactic acid, are known to exfoliate the skin gently, favoring cellular renewal and giving brightness.

Beta-hydroxy acids (BHA)

BHA, like salicylic acid, are ideal for fatty and acneic skin, penetrating into the pores to remove dead cells and excess sebum.


Ceramides help to strengthen the skin barrier, helping to keep the skin hydrated and protected from external agents.

Hyaluronic acid (HA)

Known for its hydrating properties, hyaluronic acid retains moisture, giving the skin a younger, tonic appearance.


Peptides are key elements in the fight against aging, stimulating collagen production and improving skin elasticity.


Retinol is a potent vitamin A derivative that promotes cell renewal, reducing wrinkles and signs of aging.

Vitamin C

With its antioxidant properties, vitamin C protects the skin from damage caused by free radicals, contributing to a bright embodiment.

What is the difference between excipient and active substance?

In cosmetics, it is essential to understand the distinction between excipients and active substances to fully appreciate the formulation of a product. The excipients form the backbone of the cosmetic, acting as a vehicle for the active ingredients and contributing to confer consistency, stability and sensation on the skin. These basic ingredients, such as emulsifiers, stabilizers and thickening agents, create the “base” of the product and often act as vehicles to transport the active ingredients to the deepest layers of the skin.

On the other hand, the active principles are active ingredients that provide specific benefits to the skin. These are the magic elixirs responsible for deep hydration, anti-aging action, improvement of texture and much more. The key to successful formulation lies in the skilful combination of excipients and active ingredients, where the excipients provide a stable and pleasant basis, while the active ingredients offer targeted and visible results.

A successful formulation is like a harmonious ballet between excipients and active ingredients. The other ingredients ensure that the active ingredients are evenly distributed, ensuring that the product is pleasant to apply and has a long life. In addition, the excipients may affect the consistency of the product, for example, whether it is a light cream or a rich lotion. The wise combination of high quality excipients and powerful active ingredients is the key to achieving a cosmetic that offers a pleasant sensory experience and visible results on the skin.

INCI cosmetics: how to read the active ingredients

INCI (International Nomenclature of Cosmetic Ingredients) is a universal language that reveals the secrets of every cosmetic product through its label. When exploring the INCI label of cosmetics, focusing on the active ingredients is essential to understand the beneficial potential of a product on your skin. Here are some practical guidelines for interpreting active ingredients.

Location in the list

Active substances often occupy the top positions of the INCI list. The order of listing reflects their concentration in the product, allowing you to identify the predominant ones. The higher the quantity, the closer the ingredient will be at the top of the list.

Familiarity with common names

Active substances are often identified by common names. For example, “Hyaluronic Acid” is known for its hydrating properties, while “Vitamin C” is a powerful antioxidant. Learning these common names greatly simplifies your reading of the label.

Chosen according to the needs of the skin

Identify the active ingredients targeted at your specific needs. If you are looking for deep hydration, look for ingredients such as hyaluronic acid; If you want to combat aging, retinol may be a choice. Adapting the selection of active ingredients to your needs ensures a more personalized skincare.

Combined active substances

An effective product may contain a combination of active ingredients that work synergistically. For example, the presence of antioxidants such as vitamin E along with hydrating ingredients can offer multiple benefits to the skin. Search for balanced combinations for optimal results.

Patch Test for sensitivity

Before integrating a new product into your routine, run a patch test on a small area of the skin to ensure that the active ingredients do not cause unwanted reactions.

Reading the INCI label of cosmetics is a skill that rewards with a conscious and personalized choice. Knowing the secrets behind each ingredient allows you to select products that suit the unique needs of your skin. An informed approach to reading the INCI label transforms your purchasing process into an illuminating experience in the vast world of cosmetics.
