Determining the best moisturizer for dry skin can depend on individual preferences and skin reactions. Based on the reviews provided, several users have mentioned positive experiences with products that offer deep hydration and effective sealing to prevent moisture loss. However, none of the reviews specifically highlight a moisturizer as the best for dry skin. Therefore, while the COLLAGEN CAPSULE PATCH [RETINOL] by MEDIHEAL is praised for its hydrating properties, it is not a traditional moisturizer. For a more accurate recommendation, it would be beneficial to look into dedicated moisturizer reviews or consult with a skincare professional.
