Skin Care Theory


When we think of skin care we will usually think of skin care treatments or skin care solutions, and while this is perfectly okay, there is more to it.

What is Skin Care?

From a ten thousand foot view of skin care the reality can be seen as a range of practices designed to support skin integrity, enhance appearance and relieve any number of skin conditions. These practices are varied taking the form of cosmetics, botulinum, exfoliation, fillers, laser resurfacing, microdermabrasion, peels, retinol therapy, and ultrasonic skin treatment. Some of these we have seen before if you have been following my posts.

The treatments are designed to resolve conditions from skin that’s too dry or too moist, to prevention of dermatitis and other skin conditions. They include wound healing, radiation therapy and medications.

Born from the blending of overlapping disciplines of cosmetics, dermatology, and
traditional medical discipline, skin care is more than medical or cosmetic subject but big business.


In the USA cosmetic and medications have been defined by the Federal Food, Drug, and Cosmetic Act. It states medications are products or procedures designed to diagnose, cure, mitigate, treat, or prevent disease, or to affect the structure or function of the body, this could include sunscreens and acne creams. The definition of cosmetic are products designed to cleanse or beautify such as make-up, cleaners, and shampoos.

You may have notice the possible crossover where sun-creams can also be moisturizer cream so it sits in both categories.

Skin Care Theory

You may be asking if skin care and dermatology are the same thing and it’s a good question. The main difference can be defined be its practice, and by this I mean skin care is traditionally or commonly practiced by non-physician professionals, like care staff or estheticians, for example.

It can also be seen to include modifications to the patients behavior and environmental in support of the treatment.

The Main Points

The basics of skin care is a mixture of medication and behavioral and environmental change on the part of the patient, for example, to protect against sun damage by using sunscreens, which is technically medication, and a crossover if it has moisturizing properties. Wearing protective clothing to reduce exposure would be a behavioral and environmental approach to protection, and avoiding being out in the hottest hours of the day.

Sunscreen is on the front line of the fight against skin damage and although sun is a great source of both vitamin C and D, unprotected exposure can cause damage. It’s the UVA and UVB rays that can cause early ageing, sunburn with the risk of cancer, and reduce the skins elasticity resulting in wrinkling and sagging.

The good news is that sunscreens have come along way over the last few years. Now these products come in the form of creams, gels or lotions with high SPF numbers, but not only that…..modern products are available as non-comedogenic for oily and moisturizing for dry skin.

Additional behavioral and environmental changes to consider when we looking after skin care are avoiding smoking as it makes you look older due to restricting blood flow to the skin, depleting nutrient and oxygen levels, and damaging collagen and elastin reducing strength and elasticity of the skin.  So too is treating your body with some respect by offering it good nutrition in the form of fruit and veg, whole grain products, and plenty of water. The things to avoid are proceed and fast food, fatty foods, sugar and salt.

Stress is something else that we need to control and not just for skin care but overall health. In terms of the effect of stress on the skin, it can make it more susceptible or sensitive to acne breakouts and other skin problems. Controlling stress can be achieved in a number of ways or a mixture of multiple approaches from exercise, good diet, enough sleep, relaxation and stress relief exercises, cutting down on caffeine and alcohol and any other stimulant that could effect you ability to relax.

Cosmetic care of the skin can help in terms of treating your skin well, from cleansing and exfoliating gently to limiting time in the bath to avoid removing naturally occurring oils in the skin. Also be careful about the cleansers you use. Try to use mild soaps and cleansers. We may all be aware on moisturizing after bathing but if you add one additional action to your routine in the form of patting skin dry with a towel rather than rubbing, which will allow the skin to retain some moisture.


There was a mention of healing with radiation therapy and medications which is something nobody can do for themselves but just a quick mention is needed here.

For serious medical conditions of the skin more drastic measure are called for, such as radiation therapy, this is used to induce skin reactions in the treated area, particularly in the axilla, head and neck, perineum and skin fold regions. For those suffering from breast cancer calendula cream may reduce the severity of radiation effects on the dark spot corrector, and although formulations with moisturizing, anti-inflammatory, anti-microbial and wound healing properties are used, there are no preferred approaches or individual products identified as best practice.

Finally EGFR or Epidermal growth factor receptors are medications designed as inhibitors used in the treatment of cancer. Common side effects include skin and nail problems like rashes, dry skin and paronychia. The prevention of this is possible with the use of emollient ointments.
