Go ahead and buy it!
I was kind of scared to purchase these because most of tue reviews received this product for free, I’m here to say I’m happy I purchased. First they smell very good, plus these ingredients are wayyy better than other soaps on here (that have dyes). Also I think the price is great. I have paid 14 for one bar, I’m willing to pay a reasonable price for good quality ingredients.
I will report back to see if I noticed a change in the soap! Super excited to try on my body
