Vitamin B12
High levels of vitamin B12 and potential acne outbreaks

There has recently been a great deal of focus on Vitamin B12. This substance is important for several processes in your body including the proper functioning of the nervous system. A deficiency can cause symptoms such as fatigue, tingling and lapses in concentration, as well as menstrual problems and depression. Such symptoms are not always caused by a lack of vitamin B12 though. Therefore don’t increase your intake just because you recognise these symptoms in yourself. You should always consult your doctor first. It is commonly thought that extra or too much of it won’t do any harm, especially if it is a water soluble vitamin like B12. But this cannot be said with certainty. What I can say is that I have been asked a few times whether extra vitamin B12 can cause acne. This, I have been looking into… (more…)

Happy Food Part 3: fish, fish and once again fish…

Part 3 of my series about happy food: oily fish. I just think of sashimi or a delicious salad with fish… I just hope that you enjoy it as much as I do. And otherwise I might be able to persuade you to enjoy it, because oily fish contains a wealth of substances that can also be beneficial for your skin and brain. You get a lot of omega-3 fatty acids and vitamin D in oily fish. What has that got to do with your skin? Perhaps more than you think. (more…)

Happy Food Part 2: the Mediterranean cuisine

Time for part 2 of my series about happy food. Do you remember? Today we are going to look at Mediterranean cuisine. Because if you ask the experts what diet will make you feel good, then most will probably say the Mediterranean diet. There are a number of scientific indications that this diet really does help our mood! (more…)

Biohack beautiful skin
Biohack yourself to beautiful skin

Good skincare is essential for beautiful skin, but if you have too much stress and not enough sleep then sadly, when you look in the mirror, this will be reflected. So, I always look at the whole picture. By that I mean looking at diet, relaxation, sleep and any potential vitamin and mineral deficiencies, as well as skincare. The best way is to tweak everything a little bit. But that is a lot to think about. How do you go about it? Keep it subtle by making small changes in all those areas. This can be done by biohacking.

Melasma
Melasma and nutrition, what do we know about it?

I’ve encountered some interesting things about melasma. A stubborn and unpleasant skin condition, perhaps better known as pregnancy mask. I was wondering to what extent food may play a part in this pigment disorder as well. I will say though, ‘unfortunately there is still a lot that we don’t know’. (more…)

Biotin

I think first and foremost that food should be enjoyed. But it would be a bonus if the food is also good for you. So, on today’s menu is vitamin B8. Doesn’t ring a bell? And if I now say biotin…? Yes, an important substance for your skin, hair and nails.

Product advice for baby skincare 2020

I’ve written a few times about baby products. Also that, as a new mum (or dad), you don’t want to succumb to the heaps of purple, yellow and blue bottles and jars available. I am convinced that all those intensely perfumed and irritating baby products play a very large part in the onset of skin problems in young children. The fact is that more than two thirds of babies up to the age of one, and more than three quarters of children up to the age of five have skin problems. Furthermore, 20% of newly born babies develop eczema within six months (Arch Dis Child, 2006).
