Lessons for Optimal Skin Care: Skin’s Function and Care

clinical creations

The skin is the largest organ within the integumentary system, the largest organ system which protects the body from damage.

Skin plays a key role in:

  • Insulation
  • Temperature regulation
  • Sensations
  • Synthesis of vitamin D
  • Protection of Vitamin B folates

Keeping skin healthy is important because the skin retains moisture and protects our body from harmful pathogens. A daily skin care routine is important for keeping skin soft and healthy. Many skin problems like acne, sensitivity, sunburn, and even skin cancer can result from inadequate skin care.

This article will discuss:

Skin’s Function

The skin has a number of functions, all important to maintain one’s overall health.

Some of the skin’s functions include:

  • Heat regulation
  • Storage of water and lipids
  • Water resistance -keeps essential nutrients inside of the body
  • Excretion – sweat regulates body temperature
  • Synthesis – absorbs vitamin D through UV rays
  • Evaporation – acts as a barrier to retain body’s fluid
  • Absorption – small amounts of oxygen, nitrogen, and carbon dioxide can enter through the skin

It serves other purposes as well, including:

  • Protection
  • Sensation
  • Communication and aesthetics

Protection: The skin blocks pathogens and provides protection from internal and external environmental factors. The layer of skin protects our:

  • Muscles
  • Bones
  • Ligaments
  • Internal organs

Sensation: Nerve endings in your skin react to:

  • Heat
  • Cold
  • Touch
  • Pressure
  • Vibration
  • Injury

Communication and Aesthetics: Skin condition can tell a lot about a person. Skin reveals one’s physical health and can aid in overall beauty.

Skin Care Tips

Skin requires daily cleansing and attention to remove the sweat and toxins accumulated throughout the day. A good skin care regimen includes:

  • Cleansing
  • Moisturizing
  • Sun protection


Skin should be cleansed daily, not just for treating adult acne. However, over-cleansing can cause skin to become dry or sensitive. Many different soaps and cleansers are available. Creamy cleansers work best for dry skin, while a clear cleanser should be used for oily skin.

Never clean your face with water that is too hot or too cold. Extreme temperatures can break capillaries in the face. While showering, aim for lukewarm water; long, hot showers cause skin to dry up.

Occasional exfoliation leaves skin youthful and glowing year round. Try facial treatments that exfoliate gently with chemicals like retinol or lactic acid.


Moisturizers are a good tool to keep skin soft. Tight skin is a sign a moisturizer is needed. Moisturizers improve the look of skin by sealing in moisture. Skin’s texture is also softened with moisturizers.

Of course, drinking water also provides the skin with moisture. Drink at least 8 glasses of water a day. Staying hydrated is a healthy way to enhance the look of your skin.

Sun Protection

Sunscreen is vital for long term skin care. Too much sun exposure can cause wrinkles, burns, or even skin cancer.

Sunscreen may be the most important part to a healthy skin care regime. Apply sunscreen 15 minutes before contact with the sun. This gives the sunscreen time to absorb into the skin. The best sunscreen to use is a broad spectrum of at least 15 SPF.

Another option for protecting your skin from the sun is choosing a moisturizer which contains SPF.

  1. Thanks for the info, I’ve been struggling to sort out a skin care routine that actually makes my skin look and feel any better. It looks like customers like this! So I’ll give it a try. How expensive are we talking though? Because with 2 teenage girls (whose skin is fine but they don’t believe me) I may have to keep it wrapped in Tamper Proof Tape to keep their hands off! Esp if it’s pricey. Thanks

  2. I’ve been using Perricone products and following his research for many years. I primarily use the Skin Clear line and his supplements; however, I also use the Ceramic products and the wonderful Peel-off mask (amazing products!)! I’d love to see more items in the Skin Clear line and in total body care (more selections of creams, lotions or body butters and shower gels, for example).

    I was disappointed when they discontinued the acne gel, however. I hope they are crafting another solution. I also hope they develop a make-up remover gel or solution that is safe and effective for sensitive skin.

    Perricone products are the ONLY ones that worked for me. (My dermatologist actually scolded me for spending too much on his products! She said I could find all the same ingredients in drug store brands. I told her that I was a believer in the Perricone formulations and happy to have good results without meds and spending even more on pharmaceuticals, derm brand in-office products, and so on. Plus, his products have NO unwanted side effects. I even told her that I had already tried her products, drug store products and ALL of the lines in fine department stores. I have spent a TON of money without results.)

    His 4-day “Prove it” Diet worked for me too! I have read all of his books and use his recipes regularly.

    I wonder what people who have nut allergies should do if they want to follow his diet though…. It’s a great diet that utilizes nuts quite a bit, but it doesn’t provide options for people who have nut allergies.

    I’ve gone on and on, but Perricone products were a godsend to me. I hope he continues to research and develop quality products.

    I would be honored to be a Perricone tester. If it works for me, then you know you have a great product!

  3. I am 61 years old and I have had a daily skin care regime from the time I was a teenager.

    I have tried and used some of, the best of the best products. I love the science and ever-changing technology in skin and health care. I want to look and feel, the best that I can.

    The cutting-edge information, ingredients and systems that are now being used to address the problems of aging, can really change your life. They have changed mine.

    When, I wake up in the morning and utilize my skin care products and supplements, I see a healthy glow, firm skin and I “THANK” the skin inventors for their research. My skin looks better now than it did, ten years ago. It is the technology in skin care and health that is keeping me “youthful” at 61.

    I would be a great tester because I am detailed in observations and would like to assist “us” baby boomers in continuing to look good and feel great!

    Thank you Dr. Perricone for your scientific research. It is one thing to get old and feel old but, your strategies are allowing us all, to age beautifully.

  4. Seeing is believing. I am 61 years young. I’ve been using Dr. Perricone’s products for several years now. When people ask me my age they never believe me.

    Yesterday, I had a doctor visit and in a conversation with the nurse, she said to me, “I’m so much older than you, so you can’t imagine what it’s like to be 50 years old.” She seriously believed I was in my 30s.

    I’ve not had any facial cosmetic surgery, and believe Dr. Perricone’s products have kept my skin youthful looking. As a result, I wear little makeup and have a healthy, clean, appearance to my skin.

    Thank you Dr. Perricone for making me smile everytime someone asks me my age.

  5. Oh and I made your crabmeat salad and my husband and I loved it. It was simple to make and so refreshing. This will be a staple in our home come spring and summer as we live in New England.

  6. I have been using your products now for about 4 or 5 years religiously. As a result my skin looks and feels wonderful and I am 51. I have three children my oldest is 30, and I am always told you have a 30 year old you look so young. Also your products last a long time, you only need a little bit. Thank you Dr. Perricone for wonderful products.
