Skin/Hair Types

Even though the terms "oily skin", "dry skin", "combination skin", and "normal skin" are still in use, new classifications are emerging based on criteria other than the level of sebum secreted, thus expanding the list of different skin types. According to a more advanced scientific methodology, we have established not 4 but 24 different skin profiles. So, what does it mean to have DP(.) skin?

The skin diagnosis that we have implemented at Typology allows us to assess the characteristics and needs of the skin based on three main criteria: sebaceous gland activity, skin aging, and oxidation factors. Following this analysis, 24 different skin typologies have emerged. Let's explore in this article what the DP(-) profile indicates.

In addition to our personal experiences, our lifestyle habits and our environment play a crucial role in determining our skin type, thus enabling a personalized skincare routine. Typology's skin diagnosis is based on all these criteria to establish these different skin types. The DP(+) profile is among them. But what exactly does this mean?

Traditionally, we distinguish four major skin categories: dry skin, combination skin, oily skin, and normal skin, defined by the activity of the sebaceous glands responsible for sebum production. However, skin is more complex than commonly believed. At Typology, using a more advanced scientific methodology, we have identified not four but 24 different skin typologies, and the DE(.) profile is one of them. How do we define this skin type? Find more information about the DE(.) skin typology in this article.

Sebaceous gland activity is not the only criterion to consider when defining skin. Exposure to oxidative stress factors and the degree of skin aging are additional criteria we have chosen to include in establishing our 24 skin typologies. So what characterizes DE(-) skin? Read on to find out.

AE(-), DP(.), PE(+), VP(-), AP(.)... these terms are far from the traditional skin type definitions: oily skin, normal skin, combination skin, and dry skin. At Typology, we have identified 24 different skin profiles, not just 4, based on a more advanced scientific methodology. But what exactly does the term AP(.) mean?

A skin type cannot be defined solely by its sebum secretion. Other factors must be taken into account to optimally customize a skincare routine. On this basis, we have identified 24 skin typologies, including the DE(+) profile. But what do these initials really mean? Let’s discover that together in this article.

To determine one's skin type and thus best adapt one's skincare routine, it is not enough to simply take into account one's level of sebum production. Based on a more advanced scientific methodology and considering other factors, we have defined 24 skin types: AE(+), DP(-), PP(.), VE(+)... what about the AP(-) profile?

Understanding your skin typology goes far beyond the labels "oily skin," "dry skin," "combination skin," or "normal skin." Multiple criteria must be taken into account that can influence skin quality, and these are precisely what we evaluated in our skin assessment. Based on a scientific methodology, we have identified 24 distinct skin profiles, including the AP(+) typology. What are its characteristics? Discover them here.

Today, thanks to extensive scientific research, we have realized that defining skin solely as oily, dry, normal, or combination is no longer sufficient. At Typology, we have identified 24 skin typologies, and the AE(.) profile is one of them. How do we define this skin type? Here is a more detailed explanation of AE(.) skin.

Oily, dry, normal, combination skin… defining your skin typology goes far beyond these characteristics. At Typology, based on a scientific methodology, we have defined 24 distinct skin typologies, including the AE(–) profile. But what do these initials stand for? Discover more information here about the AE(–) skin typology.

Although there are traditionally four skin types, at Typology we have devised a scientific methodology based on three universal criteria, thereby unveiling 24 distinct skin typologies. In this article, we will explore AE(+) skin in greater detail. What does this classification mean? Which skincare routine is best suited for AE(+) skin? Keep reading to find out.

Sensitive skin is hyper-reactive. This manifests as tightness, tingling, itching, irritation, heat sensations, and sometimes redness. These discomforting sensations appear in an exacerbated manner in response to stimuli. These symptoms can manifest on the face or all over the body. It is often advised against performing exfoliations on this type of skin. But what is the real story? Let's focus.

Sensitive skin requires special attention. Often prone to redness and allergic reactions, certain active ingredients can be particularly aggressive. Here is a list of ingredients to avoid if you have sensitive skin.

If you have dry skin, prone to redness, irritation, or even scaly patches, it is essential that you identify which ingredients and/or cosmetic actives to avoid so as not to worsen the situation. We provide you with some guidance here.

This question is quite common. It's true that dry skin is often sensitive, but sensitive skin is not necessarily dry. We'll explain why.

A skin that reacts to the slightest change or following the application of a conventional skincare product deserves your attention. This condition should be closely monitored to prevent skin damage and the permanent onset of redness. Intolerant, reactive, sensitive, allergic... these are just some of the terms that can be used to describe this type of skin. How can we better understand this? Are there differences between all these terms? We answer your questions.

Choosing the right skincare products for oily skin can be a daunting task. While the trick is knowing which ingredients can balance sebum levels and prevent acne breakouts, it is equally important to avoid harmful substances that can worsen sebum production.

It is possible for mature skin to experience skin issues such as a breakout of blemishes. However, it's not easy to know how to address the causes of these blemishes and signs of aging simultaneously. Discover in this article how to care for mature skin with blemishes, and thus no longer have to compromise between acting on wrinkles or on blemishes.

It is widely known that clean skin equates to healthy skin. However, cleansing can sometimes do more harm than good. If you wash your face too frequently, too harshly, or using soaps with aggressive ingredients, you risk damaging your skin. The irritants found in traditional soaps can cause dryness, contact dermatitis, inflammatory acne, and disrupt the delicate balance of the skin's pH.

A sensitive skin and an allergic skin respond easily and excessively to various stimuli. So, how can we distinguish between them?

Typically, there are four types of skin, based on sebum production: oily skin, combination skin, normal skin, and dry skin. Contrary to popular belief, each can temporarily experience dehydration issues. But how can you identify signs of skin dehydration? We provide clarity on this topic in this article.

Theoily skin is due to an overactive sebaceous glands that secrete sebum excessively (hyperseborrhea). It tends to shine, especially around the nose, forehead, and chin (T-zone of the face). What daily habits can be adopted to limit this phenomenon?

Whether the skin appears oily and shiny, the pores are enlarged, the complexion is dull, or blemishes form... these are daily occurrences for individuals with oily skin. Let's explore together the origins of this skin imbalance.

Various factors can lead to excessively dry skin that begins to peel. Sometimes unsightly, these "skin flakes" can itch. But what are the physiological reasons for skin peeling? How can this phenomenon be avoided? Typology provides information on this subject.
