“This foot cream contains Menthol, Rosemary, Pine and Lavender which provide nourishing and protecting care for the feet.”

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, c12-15 alkyl benzoate.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).
