The most common type of vascular headache is migraine. Migraine headaches are usually characterized by severe pain on one or both sides of the head, an upset stomach, and at times disturbed vision.
A migraine is a severe, throbbing headache that usually begins on one side of the head but may affect the whole head. Attacks can last for hours or days and may be preceded by warning signs. The precise underlying cause of this type of headache is unknown. The prevailing theory is that they are sparked by spasms in the arteries that supply blood to the brain.
There are basically two types of migraine: one without aura (a group of visual symptoms) which is characterized by nausea, vomiting and visual disturbances; and with aura which has warning signals like flashing lights before the eyes. A migraine can last from three hours to three days. Menstrual periods and certain specific foods are supposed to be the main reasons and that is why women are more susceptible to migraine than men.
What Causes Migraine?
Some people who suffer from migraines can clearly identify triggers or factors that cause the headaches, but many cannot. Potential migraine triggers

Skin rejuvenation can be confusing to even the most informed patients, and understanding how directed and combination therapies act to deliver results, is crucial. In general, the degree of effect is directly related to the depth of penetration in the skin. Skin can be divided into three layers, the epidermis, constituting the outer layer, and the dermis, the inner two layers. Therapies are classified as superficial, medium, or deep based on their depth of penetration. The three most common treatment modalities used for skin rejuvenation are chemical peels, mechanical dermabrasion, and lasers.

All three modalities can be used for superficial, medium, or deep rejuvenation.Medical grade skin care products act to hydrate skin, increase exfoliation, build collagen, and treat skin discolorations and blemishes. Topical vitamin therapy is a common, minimally invasive therapy, of which, the most relevant to skin rejuvenation is tretinoin, a vitamin A derivative. It acts to rejuvenate, by thickening the epidermis and decreasing photoaging, including: dyschromias and brown spots, in the short term and increasing collagen production with a decrease in fine wrinkles with longer courses. Hydroquinone and Kojic acid are topical bleaching agents that inhibit melanin production: lightening age spots, imporoving melasma, as well as other causes of hyperpigmented blemishes.

Superficial rejuvenation primarily includes glycolic acid and jessner chemical peels and acts on the epidermis, decreasing discolorations and blemishes while allowing the germinal layer of the epidermis to regenerate. Additionally, they also act to increase superficial collagen formation in the dermis, improving fine wrinkles. Lasers can be used to perform “micropeels,” acting on the epidermis only, with benefits similar to the other superficial rejuvenation procedures.
