We are all looking for ways to reduce our environmental impact, whether that’s holding your weekly shop in your arms over opting for a plastic bag or having your reusable water bottle always in tow.

The beauty industry, in particular, is one of the biggest offenders of single-use plastic waste but until recently, there were few alternatives.

From refillable and recyclable packaging, to plastic-free alternatives, some of the biggest beauty brands in the biz are getting creative with ways to reduce waste. But one of the more surprising solutions goes back to basics in the form of solid bars. We’ve seen a massive resurgence in soap bars as well as shampoo and perfume in solid form, but the latest, cleansing bars may just be the most innovative yet.

Forget all preconceived ideas of drying and harsh soap bars, these sustainable solutions are not like their predecessors. They are jam-packed with natural and skin-friendly ingredients that will not strip your face’s natural barrier with harsh preservatives or suds-inducing detergents. Many formulations have been reinvented without chemicals like SLS (sodium lauryl sulfate) to nourish skin and remove oil, dirt or makeup and some even have exfoliating properties.

While our beauty routines are progressively getting more complicated and scientific with a new beauty buzzword every week, there is something comforting about the simplicity of this beauty hero that is gentle, cost-efficient and eco-friendly.

Cleansing bars also tend to be housed in minimal packaging like recyclable cardboard or cork boxes to help you in your fight against excess plastic.

ARgENTUM le savon lune Illuminating Hydration Bar

ARgENTUM

The first time we used this facial cleansing soap we were amazed by its makeup-removing ability — not a trace of face paint remained. Occasional breakouts have been reduced to extinction, and despite the lack of any grainy texture, it exfoliates better than most scrubs tested. It’s wildly expensive, but it has lasted the better part of a year.
