The Dermis lays below epidermis. Dermis consists of net work of collagen fibers which is responsible for elastic properties of skin. Sebaceous glands associated with hair follicles and sweat glands, are all present in dermis and get blood supply from the subcutaneous tissue present below dermis. Sebaceous glands get activated during puberty and produce an oil like substance sebum sebum.

Ayurveda description of Normal Skin
Even though skin harbors tridoshas it is mainly dominated by vata. Vata is responsible for the perception of touch, secretions from glands (sweat, sebum) , blood circulation and movement of nutrients between cells and interstitial fluids.
Acharya charaka has said
“Kupitastu khalu shareere shareeram nanavidhairvikaarairupatapati balavarnasukhaayushaamupaghaataaya”
“This means- vata when aggravated afflicts the body with various types of diseases and affects the strength, complexion, happiness and span of life.”
For a healthier skin the vata should be always in normal balanced condition. The balanced vata keeps all other tissues and remaining two doshas in healthy condition. The imbalanced vata vitiates the tissues of skin and leads numerous skin problems.”
The Inner Physiological processes and skin :
The inner physiological processes like digestion, metabolism, elimination of waste products etc directly affect the beauty of skin.
The process of digestion is carried out by agni or fire which is present in our digestive system.
(Agni is the body fire, which is responsible for transformation of one substance to another. It breaks down the food substances, eliminates toxins and wastes, maintains body temperature, and resists the invasion of microbes by maintaining strong body immunity.
The body fire, which is assisted by balanced doshas, digests the food completely to form Pakwa Anna rasa (the liquid form of food which is completely digested by digestive enzymes), which is ready to get absorbed by body tissues. According to ayurveda Pakwa Anna Rasa nourishes the body and its components to keep the body devoid of diseases. But when body fire is impaired there will be an incomplete digestion of food forming Apakwa Rasa (indigested food). The indigested food fails to nourish the body components leading to lowered body resistance. Due to indigestion toxins start accumulating in body.)
An unhealthy diet and life style imbalance doshas and the imbalanced doshas impair agni. Due to impaired agni toxins accumulate in body. These accumulated toxins affect the health of skin and the skin loses its luster and glow, dark circles, acne and pimples start appearing, wrinkling of skin starts in an early age.
