<br /> <br />Introduction<br />Collagen is a natural protein that forms the primary component of connective tissue found in skin, bones, tendons, and cartilage. Skin collagen is one of the most important components for maintaining skin's youthfulness and elasticity. As we age, the body's production of this vital protein declines, leading to signs of aging such as wrinkles and sagging skin.<br /><br />What is collagen?<br />Collagen is a fibrous protein that makes up approximately 75% of skin's dry weight. It is composed of amino acids, most notably glycine, proline, and hydroxyproline. It occurs in the body in the form of triple helical chains that contribute to supporting tissue structure and giving skin strength and elasticity.<br /><br />Functions of Skin Collagen<br />Maintaining skin elasticity: Collagen acts as a support network that maintains skin tone and smoothness.<br />Strengthening the skin's protective barrier: Protects the skin from environmental aggressors such as UV rays and pollution.<br />Accelerating cell turnover: Contributes to the repair of damaged cells and stimulating the growth of new ones.<br /> Preventing Wrinkles: Collagen deficiency leads to thinning skin and the appearance of fine lines.<br />Causes of Skin Collagen Deficiency:<br />Aging (gradual decline begins after the age of 25).<br />Excessive sun exposure.<br />Smoking.<br />Imbalanced nutrition.<br />Stress and lack of sleep.<br />How can we stimulate collagen production naturally?<br />Healthy nutrition:<br />Eat foods rich in vitamin C (such as citrus fruits and strawberries).<br />Foods rich in amino acids (such as eggs, meat, and fish).<br />Zinc and copper (such as nuts, seeds, and legumes).<br />Avoid bad habits:<br />Stop smoking.<br />Reduce sun exposure and use sunscreen.<br />Collagen supplements:<br />Available in powder or capsule form.<br />Some studies indicate an improvement in skin elasticity after 8-12 weeks of use.<br />Topical skin care:<br /><br />Use creams containing retinol or peptides.<br /> Apply masks containing marine collagen.<br />Cosmetic techniques to stimulate collagen:<br />Microneedling: Stimulates collagen production by pricking the skin with fine needles.<br />Laser therapy: Promotes collagen formation in the deeper layers.<br />Platelet-rich plasma (PRP) therapy: Used to stimulate tissue regeneration.<br />Summary<br />Collagen is the foundation for maintaining youthful and beautiful skin. Although its production declines over time, adopting a healthy lifestyle and using appropriate treatments can help boost its levels. Early skincare is a long-term investment in skin health.<br /><br />Al _ Mustaqbal University, the first university in Iraq<br />Prepared by: Shahad Nawras Abbas<br />
