The Even Tone Cleansing Bar by Urban Skin Rx is a great option for those looking to address dark marks and uneven skin tone. Irene, the reviewer, appreciates the gentle exfoliation and cleansing properties of this product. She particularly likes the non-abrasive sponge that comes with it, which is gentle on the skin. The bar creates a gentle lather that effectively cleanses the face without leaving it feeling overly stiff or dry. Irene advises using it every other day instead of twice a day, as it may cause irritation for those with sensitive skin. However, for individuals dealing with hyperpigmentation or seeking to even out their complexion, she highly recommends this product. Overall, the Even Tone Cleansing Bar is a suitable choice for those looking to improve their skin's appearance and texture.
