I've read that
vitamin A can help reduce stretch marks, as it stimulates the renewal process of epidermal cells which result in a thickening of the epidermis, and improves skin elasticity. The skin on the breasts is very delicate, and the weight of the breasts themselves are constantly stretching it - so it's possible that vitamin A treatment will improve - or at least maintain - perkiness. Anyway, I'm off out to get me some! Perhaps this could be the beginning of another breast experiment?
