Firming cream for breast and décolleté Arma-Bust helps to maintain breast shape and skin elasticity even during periods of hormonal changes or weight fluctuations. Arma-Bust firming cream is safe to use during pregnancy to prevent stretch marks and maintain skin elasticity. It can also be beneficial as a breastfeeding cream, supporting your stretching skin. However, it is important to remove all cream from the nipple area before nursing your baby! Remember, no cosmetic products should be ingested by little children.
