The Sanskrit word Twacha is derived from the root Tvach samvarane, meaning to cover the body. The skin is the seat of Vata dosha. Tactile sensation is the attribute of Vata dosha. The sensory stimuli from the skin are carried by Prana Vata (one among the five divisions of vata) to the brain. The sensation of touch is more on the tip of the tongue, eyes and the tip of the little finger.
The tvacha is the subsidiary tissue (upadhatu) of Mamsa dhatu. Susrutha has mentioned 7 types of skin viz. Avabhasini, Lohita, Shewta, Tamra, Vedini, Rohini and Mamsadhara, whereas Charaka has mentioned only 6 layers.
The skin is also the seat of Pitta dosha. Bhrajaka pitta (subtype of Pitta) located on the skin is responsible for the metabolism of the skin and maintenance of body temperature. Vyana Vata, sub type of Vata dosha expresses the colour of the skin and secretes the sweat from sweat glands. The sweat (sweda) is the waste of medho dhatu, sebum (majja mala) is the waste of majja dhatu and hair and nails are wastes of Asthi dhatu.

In Ayurveda, inner and outer beauty is intimately related. The more we nurture ourselves, the more radiant we become physically and expressively – regardless of our particular body shape or proportions. Ayurveda has always understood beauty to be the product of general physical health and appropriate daily care. It is not just a cosmetic event. To enhance beauty, one should realize the importance of self-care in our increasingly fast-paced and chaotic world.
