Homemade cosmetics world is very fascinating but it could be potentially dangerous if don’t follow the correct procedures and the safety rules.
Find below 7 facts you should know before starting to create your own DIY cosmetics.

homemade cosmetics safety rules


  1. If you are a homemade cosmetics beginner, I suggest you to stick to the DIY cosmetic recipes you can find on this blog or in others before starting to formulate your own recipes or to make changes to existing formulas.
    Some ingredients could negatively interact with others or require certain pH conditions, so it’s very important that you get enough experience before doing things on your own.

  2. You should also pay special attention to procedures and be extra careful when you heat beakers and use blenders or other tools that could hurt you. It’s also recommended to use disposable gloves and to protect your eyes and face with laboratory glasses and safety mask.
    Make sure that the surfaces of your kitchen and all the tools and containers are perfectly clean to avoid contaminating your own DIY cosmetics.

  3. Be very careful when you measure the ingredients and always check the product page of the ingredients you bought to make sure the doses of the formulas you are following are not exceeding the limits. Also, 1,5 g of a liquid ingredient are very different from 1,5 g of the powder version of the same ingredient, so make sure you are using the correct one.

  4. Never measure by eye!!! If you don’t exactly stick to the doses and don’t use a balance with at least a 0.05 g accuracy, you could add more quantities than needed and the result could be dangerous for your health. The regular kitchen balances with 1 g accuracy are not suitable for homemade cosmetics formulas.

  5. Be informed and read a lot about homemade cosmetics and ingredients in blogs, forums and books. Discussion groups are very helpful when you have doubts and questions.

  6. If you want to stick to natural and toxic free cosmetics, always check the nature of the ingredients you find in cosmetic recipes, because some of them could contain ingredients that are not compliant to it.
    For your info, all the recipes of this blog only contain natural and toxic free ingredients that are usually allowed in Eco-Cert cosmetics (and other similar entities).

  7. Never use herbal infusions or starch in creams or other water based cosmetics that are meant to last for more than 2 days. Infusions are great and very beneficial when immediately used but, even if you add a natural preservative or anti-oxidants in your cosmetics, they tend to oxidize and facilitate the bacteria proliferation. The result? Your cream will be rotten and will lose its properties in few days!
    I know that many people use herbal infusion anyway in long term DIY recipes. However, think about commercial juices and tea bottles: even if they contain strong preservatives and anti-oxidants and are prepared in extremely high hygiene conditions (of course we cannot even compare our home kitchen with it), they tell the consumer to use the content of the bottle within 2-4 days once opened. So, how could we expect that it wouldn’t affect homemade cosmetics? Please also note that a homemade cosmetic can never been considered as “not opened yet” because, as mentioned before, our kitchen are way far from being considered sterile and the tools we use cannot be compared with the ones of a cosmetic lab.
