Type of Skin
Several principles are used to categorize the different kinds of skin. For example, Fitzpatrick’s classification, first described in 1975, is based on skin color and its response to sun exposure. It is used to regulate the appropriate type of sun protection factor or to predict the risk of skin cancer, among others. However, from a cosmetic point of view, skin is classified according to several factors related to its balance: sebaceous secretion, hydration and sensitivity level. Thus, each type of skin will have its own characteristics and require different cares. The type of skin is determined by genetics, although it will also be affected by other factors and can change with time.
Based on these characteristics, there are five types of healthy skin: normal, dry, oily, combination (both oily and dry skin) and sensitive. Below, we describe the main characteristics of each type of skin.
This skin is neither too dry nor excessively oily. It has a regular texture, no flaws, and a clean, soft appearance, and it requires no particular maintenance.
Sensitive skin is more likely to react to stimuli that have no effect on normal skin. It is a delicate skin that is often accompanied by unpleasant sensations such as heat, tightness, redness, or itching. This form of skin loses its barrier (or protective) function, allowing bacteria and irritating chemicals to easily penetrate and raising the risk of infection.
It is characterized by a tightness and roughness in the body. Desquamation, itching, redness, and small cracks may appear, as well as an ashy gray hue. Cracked skin is commonly found on very dry skin and appears as little fissures that can become deeper and even bleed in more acute situations.
Atopic dermatitis is a skin condition characterized by dry skin that produces desquamation and irritation, as well as bothersome symptoms like itching. The main cause is genetic predisposition, although other factors such as the environment, allergies, food, and even some clothing can trigger or aggravate the illness.
The appearance of oily skin is porous, humid, and brilliant. Excess fat synthesis by the sebaceous glands causes it, and it is mainly governed by hereditary and/or hormonal factors. It’s common in teenagers and young adults under 30 years old, and it’s generally associated with acne.
Skin With A Combination
Because the distribution of sebaceous and sweat glands is not uniform, it exhibits both dry and oily skin characteristics depending on its location. The T-zone (forehead, nose, and chin) is frequently oilier, but the skin on the cheeks is average or dry.
Skin With Scaly Texture
Skin desquamation, or the detachment of large scales from the epidermis, can occur as a result of repeated skin irritation caused by environmental conditions such as the sun, wind, dryness, or extreme humidity. Desquamation, on the other hand, can be caused by a variety of conditions, including an allergic reaction, a fungal or staphylococcus infection, an immune system disease, or cancer, as well as oncological therapy. Desquamation is commonly accompanied by itching in these situations.
Infections, heat, allergies, and immune system issues are just a few of the dermatological causes and diseases that can cause red spots or rash.
Moles On The Skin
Moles are black patches or spots on the skin that most people get during their youth or adolescence. They are caused by pigmented cell clusters. They are generally innocuous, but if they change size, shape, or color, or if itching or bleeding develops, it is important to consult a dermatologist, as some may become malignant.
In general, it’s vital to pay attention to your skin’s appearance because certain traits, regardless of your skin type, can indicate a skin problem.
