Mens Skin and Womens Skin Differences

2009-12-13 05:29:29

Mens skin and womens skin do have some key differences and it is these differences that may require the use of unique skin care products and skin care treatments. It may not necessarily be prudent for men to use womens skin care products and for women to use skin care products specifically designed for men. However, some experts believe that as long as the skin care products are good quality, then they are suitable for either gender. This may be true for some types of skin care products, but keep in mind that there are real differences in skin properties between the two genders. Therefore, it is logical that men and women should use different skin care products in certain situations.

There are six key differences in skin properties between a man and a woman. Of course, not all of these differences are necessarily applicable to all individuals. Each person s skin has its own properties that are determined by a number of factors such as heredity. However, in general, a man s skin does show differences when compared to women s skin.

Sebaceous Glands

Mens skin has smaller sebaceous or oil glands. This is opposite to what most people believe to be true. Absorption of active ingredients in skin care products is primarily through these glands, and therefore this is a consideration in the formulation of products for proper mens skin care.

Oily Skin

Despite the fact that a mans skin has smaller oil glands, mens skin is generally more oily than womens skin. This is due to the male hormone testosterone, which is responsible for the skin generating a higher amount of oil secretions. The female hormone estrogen results in womens skin secreting less oil. After the age of 50, the oil secretions in mens skin tend to slow down making mens skin closer to women s skin in the degree of oiliness.

Higher oil production in the skin means that a man's skin is more susceptible to acne related problems and other blemishes. Therefore, skin care products for men need to take this into account in order to function as required.

Skin Thickness

A man's skin is thicker than a woman's skin. This means that women are more vulnerable to damage of the skin caused by the sun s UVA rays and is one of the principle reasons why female skin suffers more from sun aging.

Fragility

The skin on a man s face is more delicate than for a woman. You wouldn t think that this is the case. However, there are some reasons why this is true:

• men historically have taken less care of their skin
• mens skin tends to be exposed more often to damaging environmental elements
• daily shaving destroys the hydrolipidic film, leading to loss of natural lubrication and protection
• daily shaving also causes scraping and nicks

All of these factors result in mens skin becoming more sensitized than womens skin and more easily irritated.

Skin Aging

As skin ages, its properties change. A mans skin gradually becomes thinner with age (about 1% per year). A womans skin is more likely to change colour and texture with age because it is more sensitive to sun damage and because of the fall-off of estrogen production after menopause. Estrogen maintains the bony framework beneath the skin, keeps it soft, resilient and healthy. Prior to menopause, women s skin thickness remains fairly constant.

The amount of collagen in the skin decreases to a greater extent in women than in men as individuals get older. This is also a main reason why women, who have similar historical sun exposure to men, appear older than men of the same age.

Skin Cancer

Skin cancer in men and women differs in a number of ways:

• men have a higher incidence of all forms of skin cancer (this applies specifically to Caucasian men in the United States)
• women develop melanoma more on the hips and lower legs (women dress in skirts and wear bikinis in the summer months)
• for a man's skin, melanoma is more prevalent on the upper back (men are often shirtless in the summer months)
• melanoma on the ears, head, face and neck is higher in males, likely due to less hair covering these areas

Nerve Fibers

Finally, there has been some research indicating that a mans skin has less nerve fibers (about 50% less) that womens skin. This can potentially explain why it is suspected that females have a greater sensitivity to skin pain.

Sex differences in humans

Appearances

See also: Secondary sex characteristics

Humans show some sexual dimorphism, but are less dimorphic than most other primates.

• On average, men are taller than women, by about half a foot (~15 cm)[1] (See sexual dimorphism).
• On average, men have a larger waist in comparison to their hips (see waist-hip ratio) than women.
• On average, men have longer canine teeth than women.
• On average, men have a greater capacity for cardiovascular endurance[citation needed]. This is due to the enlargement of the lungs of boys during puberty, characterized by a more prominent chest.
• On average, men are stronger than women. This is due to a greater capacity for muscular hypertrophy as a result of men's higher levels of testosterone.
• On average, men have more body hair than women.
• Men s skin is thicker (more collagen) and oilier (more sebum) than women s skin.[2]
• Women's skin is warmer on average than men's.
• In men, the second digit (index finger) tends to be shorter than the fourth digit (ring finger), while in women the second digit tends to be longer than the fourth (see digit ratio).
• Women have a larger hip section than men, an adaptation for giving birth to infants with large skulls.
• Men have a more pronounced 'Adam's Apple' or thyroid cartilage due to larger vocal cords (and deeper voices).

Health

Women live longer than men in most countries. One possible explanation is that more men die young because of war, criminal activity, and accidents. The gap between males and females is decreasing in many developed countries as more women take up unhealthy practices that were once considered masculine like smoking and drinking alcohol, and more men practice healthier living. In Russia, however, the sex-associated gap has been increasing as male life expectancy declines.

The World Health Organization (WHO) has produced a number of reports on gender and health.[16] The following trends are shown:

• Overall rates of mental illness are similar for men and women. There is no significant gender difference in rates of schizophrenia and bipolar depression. Women are more likely to suffer from unipolar depression, anxiety, eating disorders, and post-traumatic stress disorder. Men are more likely to suffer from alcoholism and antisocial personality disorder.
• Worldwide, more men than women are infected with HIV. The exception is sub-Saharan Africa, where more women than men are infected.
• Adult males are more likely to be diagnosed with tuberculosis.
• Before menopause, women are less likely to suffer from cardiovascular disease. However, after age 60, the risk for both men and women is the same.
• Overall, men are more likely to suffer from cancer, with much of this driven by lung cancer. In most countries, more men than women smoke, although this gap is narrowing especially among young women.
• Women are twice as likely to be blind as men. In developed countries, this may be linked to higher life expectancy and age-related conditions. In developing countries, women are less likely to get timely treatments for conditions that lead to blindness such as cataracts and trachoma.
• Women are more likely to suffer from osteoarthritis and osteoporosis.

Sensory

Main article: Sex Differences in Sensory Systems

• Females have a more sensitive sense of smell than males, both in the differentiation of odors, and in the detection of slight or faint odors.
• There is also indication that females are better at discerning differences in colours, while males are more aware of, and capable of discerning movement.
• Females have more pain receptors in the skin. That may contribute to the lower pain tolerance of women.
• Males have a more developed sense of direction.
• Males have a more developed sense of spatial awareness.

Other health differences

• Women generally have a higher body fat percentage than men.
• Women usually have lower blood pressure than men, and women's hearts beat faster, even when they are asleep.
• Men generally have more muscle tissue mass, particularly in the upper body.
• Men and women have different levels of certain hormones. Men have a higher concentration of androgens while women have a higher concentration of estrogens.
• Adult men have approximately 5.2 million red blood cells per cubic millimeter of blood, whereas women have approximately 4.6 million.
