Understanding Oily Skin
What is oily skin?
Oily skin is characterized by excessive sebum production by the sebaceous glands. Sebum is a natural oil-based substance that protects the skin and helps maintain hydration. When produced in excessive amounts, however, it can impair skin quality and alter the appearance of the face. This skin type often has a thicker texture, a shiny finish, and a tendency toward imperfections. Understanding how oily skin functions makes it possible to adopt an appropriate cleansing and skincare routine in order to preserve its beauty and health.
The causes of excess sebum
Several factors can explain excessive sebum production. Hormonal fluctuations play a major role, particularly during adolescence or periods of stress. Skin type may also be influenced by genetic factors that affect sebaceous gland activity. Environmental factors and pollution can further stimulate the pores and encourage the appearance of impurities. The use of overly aggressive skincare products can disrupt the skin barrier, triggering a defensive response in which the skin produces even more sebum to compensate.
Signs of oily skin
Oily skin can be identified through several visible signs. The face often appears shiny, especially on the T-zone, which includes the forehead, nose, and chin. Pores may appear enlarged, and the skin may be prone to breakouts, blackheads, and sometimes acne. Makeup generally holds less well due to the presence of oil on the skin’s surface. Despite these characteristics, it is worth noting that oily skin can retain a plumper appearance and may show dehydration-related wrinkles less quickly.
Mistakes to avoid with oily skin
Washing the face too often
Cleansing too frequently can produce the opposite effect of what is intended. When the skin is stripped or irritated, it responds by increasing sebum production to protect itself. It is therefore preferable to adopt an appropriate routine using gentle cleansing products that respect the hydrolipidic film. Our products for oily skin are formulated to deliver effective cleansing while preserving the skin’s natural balance.
Using overly aggressive products
Some products designed for oily skin contain drying agents that can weaken the skin. Overly strong formulas may cause redness, intensify imperfections, and damage the skin barrier. It is recommended to choose cleansing skincare products that provide softness and purifying properties without aggressing the epidermis. Algotherm products follow this approach by combining performance with respect for the skin.
Neglecting hydration
A common misconception is that oily skin does not need hydration. In reality, all skin types require hydration to function properly. Dehydrated skin may produce more sebum to compensate for this lack. Applying a suitable lightweight cream or fluid helps improve the overall appearance of the face.
Steps for effective cleansing
Cleansing gently morning and evening
Cleansing is the first essential step in maintaining clear skin. It removes pollution particles and excess sebum accumulated throughout the day or night. Using a cleanser suited to oily skin helps preserve the skin barrier and prepares the skin to receive subsequent skincare products. Morning and evening use is generally sufficient to maintain optimal balance.
Exfoliating regularly to prevent clogged pores
Exfoliation promotes cell renewal and helps remove dead skin cells that clog the pores. Gentle exfoliation refines skin texture and limits imperfections. It can be performed once or twice a week depending on skin type. This step enhances the effectiveness of subsequent products and reveals a more radiant complexion.
Toning to balance sebum
Using a toning lotion can complete the cleansing routine. It helps tighten pores, refresh the skin, and restore balance after cleansing. This step enhances the effectiveness of the skincare applied afterward and provides an immediate sensation of purity and comfort.
Hydrating with suitable products
Hydration is essential for all skin types. It strengthens the skin barrier and helps limit excessive sebum production. Applying a face serum followed by a lightweight moisturizing product helps maintain supple, comfortable, and visibly healthier skin.
Facial skincare products to include in an oily skin routine
