Carbon Theory Charcoal and Tea Tree Oil Facial Cleansing Bar Review

carbon Theory Review

If you’re from the UK, you may have heard about Carbon Theory. I received an advert for their Charcoal and Tea Tree Oil facial cleansing bar on Instagram and was immediately intrigued. You might be too when you read these claims:

– Using three ‘powerful natural ingredients’ (Activated Charcoal, Tea Tree Oil and Shea Butter), this soap is ‘dermatologically proven to prevent breakouts and keep your skin clear, balanced and hydrated’.

– This facial cleansing bar will allegedly ‘transform breakout and acne prone skin’ as the Activated Charcoal will ‘draw out dirt and unblock pores’, while Tea Tree Oil will ‘kill bacteria and reduce inflammation’.

Wow, right?

On their website, there are thousands of rave reviews left by fans of the soap.

There, I also learnt that the soap is vegan friendly and cruelty free, and best of all: it was only £6! For the price, I thought, ‘What have I got to lose?!’

First impressions

The bar arrived in a resealable plastic pouch, but now Carbon Theory have started selling plastic-free bars that come in paper, which is great for those who are trying to live low-waste lifestyles (like me!)

When I received my first order I was immediately impressed with the design of the bar. It is charcoal black and has Carbon Theory’s logo stamped on it. It’s quite striking.

This facial soap is a bar soap, not a liquid soap such as a gel or foaming cleanser. Although this can sound scary, this bar differs from the typical bar soap that we use to clean our hands. It’s formulated to be more gentle and shouldn’t disturb the skin’s pH level.

The facial soap has a mild scent to it, but I think this due to the tea tree oil.

How to use this cleanser

To use the soap, wet your hands and face, then lather it up in your hands and it’ll produce a loose foam. The directions on the packaging say to use the foam to wash your face for 30 seconds, then rinse off.

It’s not a foaming cleanser so don’t expect a thick foam, but it’s pleasant on the face. I try to avoid foaming cleansers anyway as they can be quite drying for the skin because of their high content of surfactants.

Carbon Theory recommends using this soap morning and night in order to see improvements in the skin.

So, does it work?

I find that this cleanser cleanses my skin without leaving it feeling dry. I think this is in part due to the Shea Butter added in the bar, which helps to leave the skin slightly moisturised rather than stripped.

I have not personally found that this cleanser has had much of an effect on my comedonal acne (spots caused by blocked comedones, or blocked pores). Although I don’t have inflammatory acne, I just get whiteheads on my cheeks, forehead and chin, I have not noticed a reduction in breakouts. This is disappointing, but there are so many other benefits with this cleanser that I have repurchased twice now!

Is it worth the price?

For £6, it is absolutely worth it in my opinion. This soap lasts me ages; using this cleanser day and night, one bar can last me 4 months. That works out at £1.50 a month!

Because the cleanser is a solid bar soap, there are no issues regarding carrying liquids when travelling (which frees up some well-needed space in your carry-on cosmetics bag). This is a fantastic benefit for me.

Another bonus for me is that it is plastic free! I have found a sustainable and affordable cleanser which actually works for my skin. And let’s not forget it’s vegan and cruelty free!

For now, I will continue repurchasing Carbon Theory’s facial soap. I am happy with how it leaves my skin and it has many benefits for me, so unless I’m recommended the ultimate spot-busting cleanser, I will be using this one for a while longer!

Had you heard of this cleanser before? Do you fear using bar soaps on the face?

Bye for now,
