Today, with the numerous scientific studies conducted, we have realised that we cannot simply categorise skin as oily, dry, normal or combination. At Typology, we have identified 24 skin typologies, and the AE(.) profile is one of them. More explanation on this skin typology follows.
What does it mean to have skin AE(.)?

Oxidation Factor OVERVIEW
Sebum Production BALANCED (.)
"A" for Absence of signs of skin ageing.
The first letter "A" signifies thatno signs of ageing are visible on the skin. Indeed, three main manifestations can impact the appearance of the face, namely wrinkles, a skin sagging (loss of volume) and loss of density. Generally, the first signs of skin ageing appear around the age of thirty, reflecting the changes that occur in the different layers of the skin (slower cell regeneration, decrease in lipid levels, weakening of the natural ability to produce collagen, elastin and hyaluronic acid, reduction in the size and number of fat cells in the fatty tissue...). Although ageing is an inevitable process, it is possible to prevent and exert some control over the various factors affecting the speed of the ageing process, and thus delay the onset of signs of ageing.
The second letter "E" stands for Exposure to oxidation factors.
The "E" indicates that the skin is highly exposed to external aggressions (solar radiation, air pollution, tobacco, stress, thealcohol...), as well as insufficient sun protection habits relative to the phototype and exposure rhythm. These factors promote the production of free radicals, highly unstable and reactive molecules that can have a lasting impact on the skin. However, this action is normal in all living organisms that consume oxygen.
However, in the event of an imbalance between the production of free radicals and the body's natural ability to neutralise them, oxidative stress sets in and skin damage occurs. Indeed, these reactive oxygen species contribute to the degeneration of skin cells, both at the level of the epidermis and the dermis. All vital components of the skin such as collagen, hyaluronic acid, elastin, lipids and DNA find themselves under attack, thereby causing damage and malfunctions.
This oxidation process can thus affect the structure of the skin, leading to premature skin ageing or even cancer. Initially superficial wrinkles that gradually deepen, less toned skin and a duller complexion can start to appear, even before old age. To slow down their action and thus prevent premature skin ageing, the daily application of antioxidant-based treatments, in addition to an appropriate sun protection , is recommended.
The point "." for Balanced Sebum Secretion.
The "." indicates a balance in sebum production. Naturally produced by the sebaceous glands, the sebum is a fatty substance that helps the skin protect itself against external aggressions and fight against dryness by contributing to the composition of the hydrolipidic film. Comfortable and soft to the touch, this skin type has a matte appearance without a shiny effect or "crocodile skin", and its skin texture is regular and uniform with pores tightened. It is naturally well hydrated, protected, and blemishes are rare. However, despite this skin balance, it also requires specific care to maintain its abilities and strengthen its regulation mechanisms.
Even with a balanced sebum production, if the skin is not properly protected, especially against the sun, and continues to be exposed to extrinsic factors (pollution, stress, tobacco...), the AE profile(.) is prone to developing signs of ageing (sagging, pigmentation spots, wrinkles...), thereby accelerating the skin's ageing process.
