Dry skin is very likely to have wrinkles and creases at earlier age the moist skin. So I think apply Vaseline could help reduce wrinkles. Wrinkles happen because of contribution of various complicated factors, and they are inevitable as we age. But we still can try to avoid some factors so that we could get wrinkles later and less. Keeping skin moist is very important. Many of us are suffering from dryness of skin today. When season is changing, I can feel my skin is rough and dull. In summer or winter, I always stay in rooms with air-conditioning, which just makes my skin drier and worse. Moisturizer is necessary to protect my skin from wrinkles.
