The Don’ts of Skincare

This is a post dedicated on what NOT to use in your skincare regime. There are two main issues I want to touch on here, and it may be controversial. If you don’t agree with what I am saying, that’s okay. I will try to include sources where I can!

Please, do not use Bicarbonate Soda on your skin. I’ve seen countless articles and tips encouraging the use of Bicarb Soda as a gentle exfoliant, or using it in a face mask. The truth of the matter is, I was one of these people too. It’s okay if you don’t know. Skin pH levels are extremely important for maintaining healthy, clear skin. If you use a substance that is very alkaline, the skin barrier is disrupted or damaged. Bicarb Soda is very alkaline and can basically make your face the perfect breeding ground for bacteria.

It increases moisture loss and can result in a chemical burn, causing scarring. Here are some medical journals I found on a thread online for reference. Article 1, Article 2 and Article 3.

The second no-no I want to touch on is lemon juice. This is another skin care treatment that I always see in magazines where celebs claim this is what they use to get their skin looking amazing.

Lemon juice is an acid, and can burn your skin. It can also lead to a condition called Phytophotodermatitis, which can lead to hyperpigmentation (one of the reasons that you normally use lemon juice to combat against) and basically makes your skin hypersensitive to light.

This is not so much about products that contain lemon or other citrus fruits, it’s the fresh produce usage of citrus in skin care that can lead to some harmful side effects. Here are some useful articles for reference: Article 4, Photograph of Hyperpigmentation from Lemon Juice.

    Wow - I had no idea! I always used lemon juice on breakouts as a teenager, as the juice is so drying and has anti bacterial properties. Thankfully now I don’t have so much of a need for it. That’s pretty scary about the bicarb soda though!

      I had no idea either. I’ve read that you can use lemon juice so long as it is diluted with water as well, because, like you said, great anti-bacterial properties. Just a bit too harsh for skin on it’s own.

    Thank you for sharing this! I have very sensitive skin and it is really important to know what to stay away from.

      I absolutely agree! Sometimes it’s not best to take advice from magazines and blogs without doing a little research first :)

    Oh, I love this! So important to set people straight. Natural ingredients and DIY can be great, but not if it’s the wrong ingredient.

    • Kate Flint

      Agreed! There are fabulous and safe ingredients to use from home, but these two are not it!!! :)
