Erasmus
Two new projects with the Erasmus University

Time for science! I undertake research projects each year together with medical students from the Erasmus University. Soon I will be carrying out two more very interesting studies. What are we going to be doing in the next few weeks? (more…)

Happy Food - part 1
Happy Food, a diet to make your skin happy too (part 1)

Happy food, the title alone generates happiness don’t you agree? There is a lot to tell you about this subject. So much so, that I’ve decided to make a series out of it. There are actually five parts in total! But let me start at the beginning… (more…)

Vitamin D acne
Vitamin D and skin

These late summer days are so fine! They make me truly happy. And something good happens when those rays of sun are on my skin. If you follow my blog you’ll know that the sun is responsible for the production of vitamin D in your skin. And that is super because this vitamin, or hormone to be more precise, has a positive effect on your immune system. During the summer months you usually have enough vitamin D in your body. In the winter, however, the supply runs out because of less sunlight. So, what can you do to have enough ‘D’? (more…)

Jetske Ultee Sun
My sun cream routine

I think that the nicest thing about Winter, perhaps, is that Spring will be here again. Because that I can thoroughly enjoy! In the last few days that initial Spring sun on your skin has been glorious. It does seem slightly crazy that in a few days we will be leaving for Lapland to enjoy our family holiday in the snow and freezing temperatures. And last month it was even -25°C there! And while I am busy packing all those thermals, an enormous pile of woolly hats, gloves and heavy snow boots, the terraces here are all full. The warm weather has come early this year; never too early for me, personally, however, it is for my website www.smeerjein.nl, which is currently being updated.

Sunny dilemma
A sunny dilemma

A couple of weeks ago I was on holiday with my family on a paradisiacal piece of earth below the equator. It was warm there, to say the least. As the only options to cool off were either under a palm tree or in the water, we spent a lot of time in the beautiful clear blue sea. However, that is when applying sun protection lapses… I was again reminded when I saw the discussion in the media, this week, about the importance of sun cream.

After sun
The reason for after sun

A couple of weeks ago I was invited by the programme Radar to speak about after sun products. I had to consider whether to do it or not, as I am not too keen on television presentations. In contrast to interviews for magazines, you have little control over what and how your story is broadcast. Some cutting and pasting can, in no time, make your carefully thought out statements sound very different than you intended. Having said that, I did give my story to Radar in the end. Because sun burn is so common. And the incorrect use of after sun can do your skin a lot of harm. For the purpose of clarity I have put it all down on paper for you.

Pregnancy and the Skin
Pregnancy and the Skin

You know that fairytale about the pregnant woman with that ‘never looked better’, healthy and radiant looking skin. Well I, myself, appeared in a different story; I was that expectant mother with the blotchy, irritated and over sensitive skin.

Vitamin D

My “Smear it all over” campaign is aimed at raising awareness to parents and children of the importance of sun protection. Unprotected exposure to ultra violet rays (UVR) during childhood increases the risk of developing skin cancer in later life.

My New Non-Profit Sun Protection Cream and the Sun Campaign ‘Smear It All Over!’

Those who regularly read my blog know that my great passion is, not only skincare products but, in fact everything to do with keeping our skin healthy. And high up on the list is, of course, sun protection. Even though we haven’t seen much of the sun for a while and are desperate for some, it is good to first stop and think about sun protection. Because the sun can cause a lot of damage even in cloudy weather. We think that in the Netherlands it isn’t so dangerous, but hardly anywhere else (in Europe) has as much skin cancer as here. Furthermore, the numbers are increasing dramatically and we are seeing it in more and more younger people. Even though an estimated 90% of the skin cancer cases are preventable! Therefore: ‘Smear it All Over!!’
