beauty, the subject of philosophical and artistic musings for
millennia, can be predicted by something as basic as hormones – in
women, but not men. Researchers at the University of St Andrews in
Fife, UK, have found that women’s facial attractiveness is directly
related to their oestrogen levels.

Miriam Law
Smith and colleagues photographed 59 women, aged between 18 and 25,
every week for six weeks. On each occasion, they provided a urine
sample for hormone analysis and gave information on where they were in
their menstrual cycle. None of the women wore make-up, nor were they
taking the contraceptive pill.

The researchers
then selected the photograph of each woman that had been taken at the
time of her highest urine-oestrogen level. As expected, this correlated
to the point of ovulation in the women’s menstrual cycles. These
photographs were rated by 14 men and 15 women, also aged 18 to 25, for
attractiveness, health and femininity.

The group
also rated two composite face images. One composite was an amalgamation
of the 10 women with the lowest peak-oestrogen levels, while the other
image was a combination of the 10 women with the highest levels (see

Facial formation

was a very strong and direct correlation between the level of each
woman’s oestrogen and how attractive, healthy and feminine they were
found to be, showing that fertility is related to attractiveness,” Law
Smith told New Scientist. The faces considered most healthy and feminine were also deemed the most attractive.

is likely that those women with higher hormone levels also had
increased levels of oestrogen during puberty – the time when the
hormone has a crucial role in determining facial appearance,” she

The amount of oestrogen produced by a
person’s body during the average seven-year-long puberty is largely
determined by heredity. The hormone has lasting effects on bone growth
and tissue formation as well as the skin’s appearance, Law Smith

So should 13-year-old girls be given
doses of oestrogen in the hope that they will grow into more beautiful
women? “Absolutely not,” Law Smith says. “It certainly may make them
more attractive, but who knows what other effects the hormone may have?”

course there may be an easier way – faking it. A further study by Law
Smith’s group found that when women wore make-up the correlation
between perceived attraction and oestrogen levels was completely
masked, because make-up improved appearance.

answers: The left-hand composite faces was from women with the highest
oestrogen levels, and was judged more attractive than the composite
face on the right, from women with the lowest levels of oestrogen.

    Thats some hot stuff… looks like increased blood flow to the face on the left, judging by the discreet color differences. Which, of course is a huge marker for attraction, and something everyone should subconsciously pick up on.
