I'd like to know if the fragrance you use is artificial? Generally I keep away from artificial smells as they irritate my skin but would love to try your product.

Yes, my fragrance is synthetic (All Classic fragrances including Channel No 5 use synthetic fragrance) I'm surprised to read that you have irritation issues with synthetics as they are usually included to avoid this exact issue.

Essential oils are are far higher in allergenic compounds such as limonene, citral, cinnamyl alcohol, geraniol and eugenol. In fact, more than half of the allergens that need to be listed in the INCI list are naturals.  I do not think that essential oils are in anyway better for my range, in fact, I would be wary of using essential oils on teenage skin.

Using synthetics allows for a more controlled chemical compound and a reliability in quality and fragrance stability. Also, from a sustainability angle, fragrance from rare or protected raw materials, such as Sandalwood, can be reproduced without the risk of extinction! It also keeps the cost at an affordable level.

I suffer from excessive sweating and I'm keen not to use a deodorant that alters body chemical make up by using harsh chemicals. Can you help?

There are no 'harsh' chemicals in UK or EU Cosmetics.

It might be useful to just clarify an important distinction. In the UK, we are regulated by the Cosmetic Regulation (EC) No 1223/2009, there is a clear distinction here between what is a cosmetic and what is a medicine. A cosmetic is defined as (I'm summarising here) 'any substance or mixture intended to be placed in contact with the external parts of the body to clean, perfume, protect and/or correct body odours.' However, any product that 'restores, corrects or modifies physiological functions' is a medicine and is regulated by the MHRA (Medicines and Healthcare Products Regulatory Authority). As cosmetic chemists, we can only produce products that fit in to the first definition.

Sweat is secreted through the Eccrine and Apocrine sweat glands in the skin. However, it is only the Apocrine sweat that releases a thicker secretion containing molecules that are broken down by our skin bacteria and cause body odour. These glands are mainly found under the armpits and in the groin area.

The term 'Harsh Chemicals' is rather emotive language based largely on misinformation. If cosmetics or personal care products were harsh on the skin, they simply will not sell. Every product has to go through various complex processes to determine their safety, including a Toxicologist's report. In my opinion, the most successful, safe and proven cosmetic active to counter Apocrine sweat is Aluminium Chlorohydrate. The Aluminium salts form a gel like structure on the skin, blocking the pore. They sit on the skin, are designed to go no further and are simply washed off the next time we bath/shower.

My 10 year old has started to get get a few spots, will your products be helpful or is this too young?

Ten is a bit too young for my formulations.

Please see the SAMFARMER products recomended age FAQ

If someone has skin that is prone to spots, there isn't a cosmetic product on the planet that will prevent it 100%. However, start with a gentle face washing routine that will minimise outbreaks and help to reduce the 'redness' associated with these outbreaks.

The SAMFARMER face wash is extremely mild but I would reccommend other brands that deal with this 'tween' age group.  SAMFARMER formulations are created for teenagers in the full throws of adolescence, oily skin and breakouts being the most common skin issues.
