Most acute skin problems, like the temporary blisters and swelling associated with contact dermatitis, stem from reactions to external irritants, such as nickel in jewelry, poison ivy sap, or insect bites, or from the swelling and pain of an infected cut. Chronic skin conditions, such as psoriasis, eczema, chronic hives, or acne, on the other hand, have internal causes, which ayurveda attributes to toxins generated by imbalances in the blood, lungs, and liver.

Tempted to corner the dermatologist you meet at a cocktail party for her best skin care advice? No need. We asked top experts in the field how they keep their skin young, fresh, and glowing 24/7. To ensure she layers on enough sunscreen ("the best way to keep skin youthful"), Garland, TX-based dermatologist Lisa Garner, MD, president of the Women's Dermatologic Society, fills the hollow of her palm (about ½ teaspoon) with a broad-spectrum sunscreen with SPF 30 or higher to coat her face, neck, and ears.

Bathing: A good quality bath can help moisturize your skin, but can dry your skin out if the water is too hot. Hot water will wash away the natural oils present in your skin. To hydrate your skin, your bath should be lukewarm and last between ten and twenty minutes. Also, a good quality moisturizing bath salt will help soften and moisturize your skin.
