When sebaceous glands do not secrete enough sebum, the skin becomes dry, is less protected and loses its natural moisture. Dry skin is often thin. The characteristics of a dry skin are fragility, a tendency to age prematurely, a tightness during the day and reddening in cold weather. In order to regain balance, your skin should be gently boosted.
When sebaceous glands are overactive, they secrete too much sebum and the skin becomes oily. Pores dilate and they might get obstructed by makeup residue and/or other impurities. Excess sebum will oxidize and offer the opportunity for bacteria to proliferate and cause infections and acne.
You have dry skin if your skin is pale and thin, pores are tightened, you do not have enough sebum and moisture, and present with wrinkles before your time.
If your skin is very dry, it is also very thin, and you feel tightness often, you have a great lack of sebum and moisture, early wrinkles, flaking, itching and even small inflammations.
One of the priorities for sensitive skin is to keep it clean. A fine skin that overly reacts to external aggressions (chemical products, cold or hot wind, coldness, pollution, cosmetics, etc.) is a sensitive skin. Sensitive skin is generally fine and dry. It can have visible capillaries (small blood vessels) that cause permanent redness localized on the cheeks and nose.
Sensibility is usually seen through tightness of the skin, redness, tingling, dryness, etc.
Mature skin is characterized by fine lines, wrinkles and sagging skin. It lacks thickness, can be dry and can have age spots. Additionally, mature skin lacks toning and has lines and wrinkles. Aging makes skin thinner and less elastic. It’s less resistant to the action of muscles, which causes the creation of wrinkles and sagging skin.
Wrinkles are the result of gradual loss of skin’s elasticity. The skin lines that are of 0.2 to 1 mm in depth are considered fine lines. If the depth exceeds 1 mm, they are wrinkles.
If your skin does not have any particular problem, that’s great! You’re lucky. Normal skin is rare in adults. It’s mostly encountered in babies and young children. However, your skin still requires care and maintenance to better deal with coldness, stress, pollution, cosmetics, chemicals, etc.
You have normal skin if your skin is pink, firm, smooth and pores are tightened. Your skin is clear with fine and tight grains. It is possible that the T-area (forehead, nose, chin) is slightly more oily.
Combination skin is determined by the distribution of sebaceous glands. The skin secrets more oil on the center of the face (forehead, nose, chin). But the sebaceous production is not excessive, as is the case for oily skin. On the cheeks, skin presents as normal to dry, as there are fewer oil glands.
Combination skin is the type of skin that nearly 80% of the 20-40 years old population has.
Acne is a very common skin problem. It is an inflammation of the skin that is characterized by red spots called “pimples”, with black and white points. The main inconvenient of acne is its unappealing appearance. Acne can occur on the face, chest, back and upper arms. It affects about 90% of adolescents and up to 30% of those between 20 to 40.
A very aggressive acne can leave deep and permanent scars. Acne is caused by overactive sebaceous glands (production of excess sebum) that provide a perfect environment for bacteria to settle. In particular, a bacteria called Propionibacterium acnes causes acne. It is advisable care carefully for acne-prone skin.
