Simple offers soothing moisturizers, makeup removers, cleansers, and toners with [niacinamide](https://lovi.care/skincare/ae/ingredients/niacinamide) and [glycerin](https://lovi.care/skincare/ae/ingredients/glycerin), suiting oily and acne-prone skin best, while the other brand is known for precise cleansers and formulas that suit balanced to oily skin.
