Let’s talk about phyto-oestrogens. The term stems from the Greek word “phyto”, or plant, and “oestrogen,” being the hormone that makes us fertile. Phyto-oestrogens, also known as plant oestrogens, are naturally occurring chemicals with a structure similar to that of the female hormone, oestrogen.


Phyto-oestrogens affect the body by attaching themselves to our oestrogen receptors[i]. Whether or not they can act detrimentally to oestrogen blocking drugs for breast cancer, the answer is unclear[ii]. This is a contentious and complicated subject matter, with inconclusive and inconsistent research surrounding it. So, what do we know?

According to Breastcancer.org, most breast cancers are hormone-receptor-positive:


About 80% of breast cancers are oestrogen-receptor positive.


About 65% of oestrogen-receptor-positive breast cancers are also progesterone-receptor-positive. This means that the cells have receptors for both hormones, which could be supporting the growth of the breast cancer.


About 13% of breast cancers are oestrogen-receptor-positive and progesterone-receptor-negative. This means that estrogen, but not progesterone, may be supporting the growth and spread of the cancer cells.


About 2% of breast cancers are oestrogen-receptor-negative and progesterone-receptor-positive. This means that the hormone progesterone is likely to support the growth of this cancer. Only a small number of breast cancers test negative for oestrogen receptors but positive for progesterone receptors.


If the breast cancer cells do not have receptors for either hormone, the cancer is considered oestrogen-receptor-negative and progesterone-receptor-negative (or “hormone-receptor-negative”). About 25% of breast cancers fit into this category.

What does a Positive Test Result mean?

Any positive test result — whether just for oestrogen receptors, progesterone receptors, or both — means that the breast cancer is considered “hormone-receptor-positive.” Hormonal therapy may help to slow or stop the growth of hormone-receptor-positive breast cancers by lowering your body’s oestrogen levels or blocking the effects of oestrogen. These medications also may reduce the risk that the cancer will come back (reoccur).

Oils such as borage, avocado, evening primrose, flaxseed & soy are examples of plant-based oestrogens. Should these ingredients be going onto and in some cases into the skin? Each of us must may decide this for ourselves. As a practising Oncology Certified Facialist Corneotherapist in Raby Bay, I choose not to use phyto-hormone based plant extracts on my health challenged clients.

My brand of choice is dermaviduals. One of only a few corneotherapy products in the world today, and the only corneotherapy line in Australia. They use premium ingredients from around the world, coupled with best practice – From animal-free testing, sterile formulating and packaging to containing no fragrance, silicones, mineral oils, amines, colours, preservatives, parabens and emulsifiers. Demaviduals is safe, efficacious, and extremely gentle on the skin.

What is corneotherapy?[i] As a progressive skin treatment methodology, corneotherapy is built on the foundation of principles that it is possible to achieve healthy skin with a functioning innate immune system, which is done by preventing or reducing structural inflammation.

By using preventative interventions that are designed to assist in the correction and restoration of the stratum corneum and barrier defence systems, it leads to homeostasis and the improved function of the entire integument. This helps to protect you from harmful substances and micro-organisms, while keeping the epidermis intact at all times.

Corneotherapy uses methodologies that are designed to correct and promote skin barrier defences that have been impaired by disease, or intrinsic and extrinsic factors. As a practicing Oncology Certified Facialist Corneotherapist in Raby Bay, corneotherapy is an innovative skincare and clinical treatment methodology that provides an individualised skin care solution adapted to the specific needs of the skin.
