The skin is the largest organ of the human body, covering the entire external surface and protecting the internal organs, muscles, and bones. In an average adult, the skin covers approximately 2 square meters and constitutes a significant portion of body weight (approximately 9 kg including the fat layer).
The skin consists of three main layers, from the outside inward.
It is the outermost protective barrier of the skin. It contains no blood vessels. It prevents water loss, defends against germs, and gives the skin its color through melanin pigment.
It is the living layer beneath the epidermis. It provides elasticity and durability to the skin through collagen and elastin fibers. This layer contains blood vessels, nerve endings, sweat glands, sebaceous glands, and hair follicles.
It consists mainly of fat cells and connective tissue. It protects the body from impacts, provides thermal insulation, and stores energy.
The skin performs many biological functions that are critical for the survival of the body.
It is the first line of defense against pathogens, ultraviolet (UV) radiation, chemicals, and physical injuries.
It regulates body temperature through sweating and the dilation and contraction of blood vessels. Through its nerve endings, it transmits sensations such as touch, heat, cold, pressure, and pain to the brain.
It synthesizes vitamin D with the help of sunlight; stores water, fat, and electrolytes. It helps excrete excess water, salt, and toxins through sweat.
Your skin completely renews itself every 28 days. Throughout your lifetime, you will have approximately 1,000 new skins.
Approximately 1 billion bacteria live on every square centimeter of your skin. This microbiome is vital for the skin's immune system.
The skin makes up approximately 16% of your body weight. This makes it the largest and heaviest organ in the body.
Every person's skin type is different. Therefore, every skin has different needs. Skin type is determined by factors such as age, gender, and genetics.
Combination skin is the most common skin type in the world. It is the presence of more than one skin type in different areas of the face at the same time. The T-zone is oily, while other areas are dry or normal.
It is a skin structure that shows excessive reactivity to environmental factors. Redness, itching, burning, and stinging sensations are common. The protective barrier function is weakened.
It is a skin type characterized by high sebum production resulting from overactive sebaceous glands. A constant shine, enlarged pores, and a tendency toward acne are observed.
It occurs when the skin is unable to produce sufficient sebum or retain moisture. A matte appearance, feeling of tightness, flaking, and a tendency toward early wrinkling are present.
It is a skin type where the moisture and sebum balance is proportional. Pores are fine and closed, blood circulation is good, and the skin is smooth and soft.
You can determine which skin type you have through the correct analysis method. For this, you need to consult a specialist. Dehydration, sun spots, redness, and irritation are determined by expert dermatologists through skin analysis.
Wrinkles are a biological result formed by the combination of the body's internal aging process and external factors.
Collagen and elastin fibers found in the dermis, the deeper layer of the skin, begin to decrease by approximately 1% per year from the age of 25. As these fibers decrease, the skin loosens, sags, and permanent marks form at folding points.
Repetitive muscle movements such as smiling and frowning turn into permanent wrinkles over time. UV rays are responsible for 80-90% of wrinkles. UVA rays from the sun cause the release of enzymes that break down collagen fibers.
As we age, the skin's natural oil production and moisture retention capacity decrease. Dry and dehydrated skin wrinkles more easily like paper and existing lines appear deeper. Gravity, sleeping position, and smoking are also factors that increase wrinkles.
Crow's feet are one of the first signs of aging, occurring because the skin around the eyes is much thinner and more sensitive than other parts of the body.
The ingredients used to protect the skin barrier and fight the signs of aging are the cornerstones of modern dermatology.
It is considered the "gold standard" of anti-aging care. It reduces fine lines, accelerates cell turnover, and diminishes the appearance of blemishes. It should only be used at night and must be supported with sunscreen during the day.
It is a powerful antioxidant. It evens skin tone, adds radiance, and protects the skin against free radical damage caused by the sun.
They act like the "building blocks" of the skin. They signal the body to produce more collagen, making the skin appear firmer and more plump.
They are "adhesive" lipids that hold skin cells together. Without them, the skin becomes dry and cracked.
It has the capacity to retain up to 1,000 times its own weight in water. It fills the skin with moisture from the inside out.
It is a versatile ingredient. It both tightens pores and soothes redness by strengthening the barrier function.
It soothes the skin, prevents water loss, and accelerates the healing process of wounds.
