People change their skincare products when their skin is unhealthy. Actually, skincare products may not be the main cause of unhealthy skin. The biggest damages of your skin come from the environment. You may not get yourself the right type of skincare products without understanding these enemies. Free radical is probably skin's biggest enemy. Free radicals are unstable molecules and atoms which tend to combine with stable ones.
When free radicals combine with skin cells, injury, irritation and death to cell parts, cell walls and collagen fibres may happen. Actually, the natural defence system of a young and healthy is able to scavenge and neutralize these free radicals.
But sun, air pollution, cigarette smoke, pesticides, poor diet, illness and stress, etc trigger more free radicals than we can absorb. As a result, our skin loses its suppleness, elasticity, resilience, healthiness and ability to self-repair.
Sunlight is not only a source of free radicals, but also UV radiations and heat. UV radiations from the sun cause significant damages to protein fibres. It may also thicken the epidermis and cause skin cancer (under severe exposure). Heat from the sun draws away moisture and making skin sensitive and dry.
Other than heat from the sun, heat from the general environmental (e.g. central heating) may lead to water evaporation from the skin. On the other hand, cold air from outdoor and air conditioning is also dry and dehydrating. Such moisture loss is unable to be compensated by skin's normal sebum and moisture production. Therefore, the resulted skin may be parched, flaky and cracked.
Other than external factor, internal factor such as hormone may also be an enemy of our skin. Production of sebum (natural oil) is affected by hormone. The moisture level of skin is also affected by hormone, Oestrogen which is a natural humectant of skin. As Oestrogen decreases with age, skin sebum and moisture decrease. Natural sebum may also be stripped by poor skincare products. This leaves your skin irritated and scratchy.
