Exam Question and Answers [100%
Correct] 2025/2026
How does the skin’s barrier function protect against environmental stressors, and what are the
consequences of barrier dysfunction?
dead skin cells (corneocytes) and lipids that act as a physical shield against environmental stressors, such
as pathogens, chemicals, and UV radiation. This barrier also prevents excessive water loss and helps
maintain hydration. When the barrier is disrupted, either by harsh skincare products, over-exfoliation, or
environmental damage, the skin becomes more susceptible to irritation, dehydration, infection, and
inflammation. Dysfunction of the skin barrier is implicated in skin conditions such as eczema, acne, and
rosacea, and can also accelerate aging by increasing the skin’s vulnerability to oxidative damage.
youthful skin appearance?
strength, structure, and elasticity. Collagen, which makes up about 75% of the skin’s dry weight, provides
tensile strength and supports the skin’s framework. Elastin allows the skin to return to its original shape
after being stretched or compressed, giving it flexibility. Over time, the production of both collagen and
elastin decreases due to factors like aging, UV exposure, and environmental pollution, leading to the
development of fine lines, wrinkles, and sagging. The degradation of these proteins results in the loss of
skin firmness and elasticity, hallmark signs of skin aging.
the removal of toxins and waste products from the skin?
consists of a network of vessels and lymph nodes that help drain excess fluids and remove toxins,
metabolic waste, and cellular debris from the skin and surrounding tissues. Lymphatic drainage facilitates
immune responses by transporting immune cells to sites of infection or injury. Poor lymphatic circulation
can result in fluid retention, puffiness, and the accumulation of waste products in the skin, contributing
to dullness, puffiness, and a less radiant complexion. Techniques such as lymphatic massage can
stimulate lymphatic flow and help promote detoxification and healthier skin.
and healing?
communicating between the nervous system and skin cells. These molecules can regulate skin functions
by controlling inflammation, vasodilation, and cell signaling. Neuropeptides such as substance P and
calcitonin gene-related peptide (CGRP) are involved in the skin’s inflammatory response, helping to
initiate healing following injury and regulating pain perception. However, an imbalance in neuropeptides,
such as an overproduction in response to stress, can contribute to chronic inflammation and exacerbate
skin conditions like rosacea, eczema, and psoriasis.
the skin’s hydration and protective function?
substance that lubricates and protects the skin. Sebum helps maintain the skin’s hydration by forming a
thin layer on the surface that prevents moisture loss, while also acting as a barrier to harmful
microorganisms and pollutants. An overproduction of sebum, often caused by hormonal changes, can
lead to oily skin and clogged pores, resulting in acne. On the other hand, a deficiency in sebum
production can cause dryness, irritation, and increased sensitivity. Proper sebum balance is essential for
maintaining healthy, well-hydrated skin.
of aging be managed or prevented?
is a natural process driven by genetic factors, including a decrease in collagen production, slower cell
turnover, and reduced skin elasticity over time. This results in fine lines, wrinkles, and thinner skin.
Extrinsic aging, on the other hand, is primarily caused by environmental factors such as UV radiation,
pollution, smoking, and poor diet. These external factors accelerate the breakdown of collagen and
elastin, leading to premature aging and skin damage. While intrinsic aging is inevitable, extrinsic aging
can be managed through sun protection, avoiding smoking, using antioxidant-rich skincare, and
maintaining a healthy lifestyle to minimize oxidative damage and promote skin repair.
prolonged UV exposure?
by creating thymine dimers, which distort the DNA structure. This damage can lead to mutations that,
over time, may result in skin cancer. UVA rays penetrate deeper into the skin and accelerate the
breakdown of collagen and elastin, contributing to premature aging (photoaging) by causing wrinkles,
sagging, and uneven pigmentation. Prolonged UV exposure also triggers the release of inflammatory
mediators that can lead to chronic inflammation, skin thickening, and a weakened skin barrier. Long-
term, excessive exposure to UV radiation is the leading cause of skin cancer, including melanoma, basal
cell carcinoma, and squamous cell carcinoma.
