Yugard facial Cream contains Retinol. Retinol work by causing surface skin cells to shed rapidly, making way for new skin cells underneath. They prevent collagen breakdown in the skin and thicken the skin to prevent formation of wrinkles. For hyper pigmentation, retinoids exfoliates dark skin cells and reduce the formation of melanin. Yugard can help improve hyper pigmented brown spots left by pimples. That is because it induces exfoliation of skin cells, so new, healthier skin cells come up faster and the pigmented cells are gotten rid of.
