Women

Nearly half of all adult women experience mild to moderate blemishes at some point in their lives- mainly due to fluctuating hormones.

Premenstrual 
So called ‘PMS blemishes’ are caused due to an increased release of the male hormone androgen which is known to alter the skin’s pH and to increase sebum secretion, a combination that can encourage blemishes.

Pregnancy
Some women experience blemishes during pregnancy while others report their blemishes cleared up. If you find yourself suffering it's likely to be due to an increased amount of androgen which is known to increase sebum production – similar to what happens with 'PMS blemishes'. 

Please note: certain medications are not safe to take during pregnancy e.g:- tetracycline, doxycycline and minocycline. Nelsons Pure & Clear does not contain any of the above substances. 

If pregnant or breast feeding always consult a healthcare professional before using any anti-blemish treatments.

Menopause
Menopause is defined as the time in a woman’s life when her reproductive cycles end. This typically occurs between the age of 45 and 60. During this transition, the ovaries start producing lower levels of estrogen and progesterone and many women find themselves suffering from hormonal imbalances expressed by hot flushes, night sweats, mood swings, aching joints and blemishes. 

Blemishes during the menopause can be explained by the dramatic decrease in estrogen levels allowing for testosterone and DHEA to cause the oil glands in the skin to produce an excess quantity of sebum which tends to block pores and hence results in blemishes.
