Creams can do several things. A good aggressive skin care regimen, is a great start.
A good face cream and daily skin care, are very important aspects in keeping a youthful appearance, it might improve the texture of the skin.
A certain amount of skin tightening may be achievable with effective topical treatments, but real facelifting requires an actual repositioning and sculpting of the tissue underneath the skin.
A good facial cream can improve skin color, texture, and decrease some fine lines and wrinkles.
All of these, when combined with sun avoidance, sunscreen avoidance and avoidance of yo yo weight gain/loss patterns and avoiding smoking can make the skin look dramatically better than if these steps were not followed.
