How to Make Anti-Pollution Skincare

Anti-Pollution Skincare

Environmental pollution is a significant problem in many large cities around the world and anti-pollution skincare is a hot new trend coming out of Asia. A significant number of studies have examined the effects of pollution on the ageing of the skin and found some alarming results.

Pollutants are very diverse, from some airborne components such as Ozone or Nitrogen Dioxide to industrial residues such as polycyclic aromatic hydrocarbon and nanoparticles. The effect that these pollutants can have on the skin depends of course on the daily environmental exposure. This exposure will vary from location to location and between individuals. However, if you live in a large polluted city then it is very likely that your skin is being exposed to significant pollution every single day.

Effects of Pollution on the Skin

Researchers have found the following effects of pollution on the skin:

  • Ozone in photochemical smog appears to speed up skin ageing, by depleting Vitamin E levels in the skin, interfering with wound-healing processes and causing oxidative stress.
  • Skin exposed to pollution areas experiences a higher sebum secretion rate, when compared to non-polluted areas.
  • There is a tendency of the cutaneous pH to decrease when exposed to pollution. One study found a higher a significantly higher amount of lactic acid in the skin in polluted areas compared to non-polluted areas.
  • Squalene and vitamin E are the main antioxidants at the surface of the skin. Squalene is decreased in polluted areas, as this antioxidant is mobilised to combat oxidative stress in the skin. Low values of both these two antioxidants is normally associated with dry skin which may be a side effect of pollution.
  • Cholesterol in the skin is decreased when exposed to pollution.

Scientific studies into Pollution and Skin

Globally, studies have found a tendency to find more skin problems in the more polluted areas of the world. Research is still ongoing into the skin’s deep layers’ reactions to pollutants.

Skin Pollution Research in China

Anti-Pollution SkincareOne study was undertaken during summer 2008 in two different districts of Shanghai, on 159 local residents: 79 subjects from Xu Jia Hui (a centre Shanghainese area), more exposed to pollution, and 80 subjects from Chong Ming, an agricultural region closely located north of Shanghai (<100 kms) and less exposed to pollution, according to official data. Researchers then measured various skin parameters, and feedback from volunteers was collected through a questionnaire.

The study demonstrated significant differences in several biochemical parameters measured in the rural Chong Ming area, as compared to the urban Shanghai area, with an increased ratio of squalene/lipids, a lower level of lactic acid and a better cohesion of stratum corneum. Both sebum excretion rate and sebum casual levels did not differ between the two districts. The volunteer’s feedback suggested a perceived link between pollution and their skin problems.

Skin Pollution Research in Mexico

A similar clinical study was performed on 96 people in Mexico City (exposed to pollution) and 93 people in Cuernavaca (less exposed to pollution). Both biochemical and clinical skin parameters were studied.

The study demonstrated significant quantitative and qualitative modifications of parameters related to sebum excretion in Mexico City compared to Cuernavaca: the participants in Mexico City noticed an increased level of sebum excretion rate, a lower level of vitamin E and squalene in sebum, an increase of lactic acid and a higher erythematous index (redness) on the face of the subjects.

How to formulate Anti-Pollution Skincare

What is anti-pollution skincare? It will either include products that prevent skin damage caused by pollution, or products that rectify skin damage caused by pollution – or both.

When you’re formulating with the overall aim of providing anti-pollution skincare, you should aim to incorporate high antioxidant levels into the overall skincare product. Living in a highly polluted area means that often your skin may feel as if it has a thick layer of grime and grease on your skin, so gentle cleansing products will be important. You may also wish to account for higher levels of sebum production by formulating skincare which has a balancing effect on the oil levels of the skin. Barrier repair functionality is also a key point to consider, as cholesterol levels are low in the skin exposed to pollution. Some people may find that pollution has a drying effect on their skin given depleted antioxidant levels. Finally, consider the pH of your products and aim to normalise skin pH by ensuring that your products sit in the correct pH range of healthy normal skin – somewhere between 4- 6.5.

So to summarise, the most important rules for formulating anti-pollution skincare:

  1. Incorporate adequate levels of antioxidants.
  2. Consider gentle cleansing products to remove grime.
  3. Aim to balance the natural oil levels of the skin.
  4. Consider strengthening the barrier function of the skin.
  5. Ensure your product provides good moisturising properties.
  6. Normalise skin pH by ensuring that your product sits in the correct pH range for the skin.

Effective natural anti-pollution skincare products would include:

  • Oil-based cleansing products
  • Balancing toners or tonics
  • Mild cleansing products that can be applied frequently and when out and about
  • Deep cleansing products that do not compromise the skin’s pH or dry out the skin
  • Cleansing masques based on adsorbent clays (enrol for our Certificate in Facial Masque Therapy)
  • Products that can be carried around in a purse and applied when out in a polluted city.
