Acne is very common; around 80% of people between the ages of 11 and 30 will be affected at some time. It occurs most frequently in puberty but it can persist into or even develop in adulthood, where approximately 5% of women and 1% of men over the age of 25 have acne. Most people have acne on and off for several years until their symptoms start to improve as they get older1.

Acne is often triggered by hormonal changes, especially in teenagers going through puberty and in women during their monthly hormonal cycle. The symptoms occur when the grease-producing glands (sebaceous glands) stimulated by these hormonal changes, produce abnormally high levels of sebum. This, in turn, causes narrowing or blocking of the pores (leading to whiteheads and blackheads) and allows normally benign bacteria to multiply, gather in the closed pores and cause inflammation, swelling and pus.

The redness of the spots (papules) is due to inflammation. If the pores rupture, the bacteria are released onto the skin surface as yellow-headed spots (pustules) containing a mixture of bacteria and inflammatory cells (pus). In more severe acne, this can produce hard, painful spots (called nodules and cysts) and these can result in scarring.

The impact of acne should not be underestimated. It is now recognised that people living with acne can experience social, psychological and emotional problems similar to people with long-term illnesses such as asthma, epilepsy or arthritis2.

Acne can run in families, but this does not necessarily mean that all children of parents with acne will develop the condition. There are a number of myths about acne that should be dispelled. Acne is NOT contagious and cannot be ‘caught’ from another person. It is NOT caused by poor hygiene or over-eating of junk foods.

Acne treatment with topical and in some cases oral therapies is very important as the fewer breakouts a person has, the less likely the chance of scarring. Picking and squeezing of spots should be avoided, and gentle skin-care regimens should be followed3. Whilst there is no actual cure for acne, it does usually improve over time and eventually disappears (although this can take several years).


Pharmaceutical (i.e. non-surgical) acne treatments that may be recommended by a pharmacist or prescribed by a GP in the UK are described in the table below.

  • Can only be used for six months because of the risk of antibiotic resistance
  • Can make skin more sensitive to sunlight, and can cause nausea, vomiting, diarrhoea and mild stomach pains
A hormonal treatment that can be used in women when hormonal conditions, such as polycystic ovary syndrome, are thought to be causing acne

  • Causes a person to bruise and bleed more easily


SEQuaderma Acne Prone Skin does not have the side effects associated with prescribed acne treatments. It works quickly, and significant improvements in acne have been seen after just 1 week’s treatment (although it may take longer to work for some people). In addition, the sebum reduction effect of SEQuaderma means that recurrences may be reduced and other topical and oral treatments needed less. It can also help patients currently on prescription medication to care for their skin better as SEQuaderma can be used in conjunction with drugs. Please check our life changing stories.
