How do I sterilize pencil sharpener blades

Not all old glass is the same - what is allowed in the container and what is not

The constant washing of hands and disinfecting hands is at least a problem for my skin. For me, that means constantly putting lotion on my hands - and that's what I'm doing with this homemade, beginner's hand cream that does not leave a greasy film on the skin.

Every Sunday between 10:00 and 10:30 a.m. in COSMO I hear something about sustainability on my ears! COSMO is the cosmopolitan radio program from WDR, Radio Bremen and Rundfunk Berlin-Brandendenburg (RBB). The talk is available here to listen to and read up on!

Zozan (Cosmo presenter): How has your skin been doing since Corona?

Shia: Given the circumstances, my skin is doing really amazingly well. I mean, I'm one of those people who tend to have permanent skin problems. Eczema and such. And every year, really every year, I curse the dry heating air in winter. Constantly washing and disinfecting hands doesn't make it any better, of course. So I make sure I drink enough every day. Studies to date have shown that drinking water softens dry and rough skin and makes the skin more elastic if the test subjects were insufficiently hydrated. [1, 2] Whether drinking more water generally improves the skin needs to be investigated more comprehensively become. By the way, I always tell by my lips whether I've drunk enough. If not, I get rough lips straight away and they really go away within a few hours if I have a good drink. Crazy! But maybe I'm just a mutant there 😉.

Zozan: I also watched the video and it's really very easy ...

Shia: This is also my recipe for beginners who otherwise use more conventional products.

100 g coconut oil - you can buy it everywhere now. 50g cocoa butter and 50g shea butter. If you don't get one of these, you can just take 100g of what you get. Then another 1 tablespoon of olive oil. I buy all the ingredients in the unpackaged shop, with the exception of coconut oil, everything is there for filling and there is coconut oil in a deposit jar, which I think is very cool.

Zozan: But you can also get the ingredients in the health food store, right?

Shia: Exactly. I heat the ingredients on very low heat until everything has melted. A water bath is also possible, of course, but it is not necessary, as I stand by and stir. I stir it well and pour this liquid mixture into a screw cap jar that I sterilized with hot water beforehand and dried well with a very clean cloth. Then just cool it down and let it set and that's it!

Zozan: But that's more of a body butter than a cream, isn't it? Isn't it too greasy?

Shia: That's right, strictly speaking, it's not a cream, i.e. not an emulsion of water and fat. But this is particularly good for dry skin. The mistake most people make is putting on as much body butter or oil as you would put cream on - it's too much! Much less is enough, which makes this homemade hand cream super economical.

Zozan: So take less and then there is no greasy film?

Shia: At least not with this DIY hand cream. Different oils and fats have different properties. Olive oil, for example, is super good for dry skin, but absorbs super slowly. Anyone who has already had more experience with oils in skin care and knows that their own skin can cope well with them - here now for advanced users - can also experiment with pure and regional oils. I often use native rapeseed oil from Germany for creaming. Almond oil from Europe, not California, is great too. And everything can be mixed, which is so cool about doing it yourself, because you can adapt it to your own skin type 💚.

Recipe: Zero Waste Hand Cream

This Zero Waste hand cream does not leave a greasy film on the skin when applied correctly (namely very sparingly 😉). This recipe is aimed at beginners who have no previous experience with body butter or oils in skin care. I recommend that advanced users experiment with more regional oils. I tolerate virgin rapeseed oil, for example, very well, also on my face. But that always depends on your skin type.


  • Small pot
  • stove
  • Clean screw cap jar that holds over 300ml


  • 100 g coconut oil
  • 50 g cocoa butter
  • 50 g shea butter (alternatively either 100g cocoa butter or 100g shea butter instead of 50g of each)
  • 1 TBSP (corresponds to about 15 g) Olive oil


  1. Put all the ingredients in a saucepan. The whole at the lowest level Heat and stir until all fats have melted. This is also possible in a water bath, but it is not necessary.
  2. Pour the melted mass into a clean glass. I like to sterilize the jar beforehand with boiling water, but it doesn't have to be.
  3. Put the glass aside and let it cool down to room temperature.


The mass, which has cooled to room temperature, can also be whipped again in a mixing bowl with a hand mixer with a mixer attachment. This makes it fluffy and easier to remove. I myself am too lazy for that and only do it if it is supposed to be a gift 😉.
