Vitamin D is actually created by your skin. When exposed to sunlight for a while (at least a half an hour) the skin will begin converting cholesterol into Vitamin D. The conversion process will continue as long as you are exposed to sufficiently strong direct, full-spectrum sunlight.
Most people get their vitamin D by exposing their bodies to the sun's rays. It typically takes at most 30 minutes of exposure twice a week to synthesize all of the vitamin D you need. You should keep in mind, however, that staying in the sun for too long could cause skin damage and put you at greater risk for developing a skin disorder or disease.
Use a sunscreen and wear protective clothing to safeguard your skin from the sun's harmful rays. Over fifty years ago, Dove® discovered the importance of moisture, as well, in maintaining healthy, beautiful skin. Dove® believes that outstanding moisturization and mild cleansing can genuinely improve the look and condition of skin.

by simulating the effects or manufacturing vit D on the skin.
No, vitamin D synthesis is a function of the integumentary system.
The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails. In addition to its barrier function, this system performs many intricate functions such as body temperature regulation, cell fluid maintenance, synthesis of Vitamin D, and detection of stimuli.
Vitamin A is required for the synthesis of rhodopsin. That's why a deficiency of vitamin A can affect night vision.
Vitamin A
The Sun causes the synthesis of Vitamin D in the skin.
Yes, vitamin B1 is essential for its synthesis.
Vitamin K
vitamin D
1. Maintenance of body temperature 2. Protection/physical barrier 3. Perception of stimuli (detects temperature, touch, pressure, pain) 4. Excretion (through sweat) 5. Synthesis of vitamin D (when exposed to sunlight/UV radiation) 6. Immunity
The function of the Integumentary System is to protect us. Without having skin, our organs would fall out, the integumentary system also keeps our temperature in check, and keeps us from dehydration and a lot more!

The dermal (or Integumentary system) is comprised of principal organs (skin, hair, nails, cutaneous glands).The principal functions are protection, water retention, thermoregulation, vitamin D synthesis, cutaneous sensation & nonverbal communication.
Your skin is responsible for synthesis of Vitamin D.
