Chemical Or Mechanical Exfoliants

Cosmetic exfoliation can be done in two ways, mechanically or chemically. Mechanical exfoliation is done physically using an abrasive such as pumice stone, ground walnut shell, microbeads or fibres. The product is physically rubbed onto the skin to dislodge dead skin cells then wiped or washed off. Chemical exfoliation is done chemically using products that contain acids that dissolve the dead skin cells. The acids used are either BHA or AHA. BHA (beta hydroxy acid, commonly known as salicylic acid) is used in many anti-ageing and acne creams. AHA (alpha hydroxy acids), such as lactic acid and citric acid, are often derived from foods such as sour milk, apples and grapes.

In terms of effectiveness, both chemical and mechanical exfoliants have their place. Chemical exfoliants are generally more effective because the strength of the acids can be increased depending on the desired effect. Chemical exfoliants also target the skin better than mechanical exfoliants which rely on the thoroughness of the user. On the other hand, it is not yet known what the long term effects of using chemical exfoliants on the skin are; moreover there is a risk of the acid burning the skin if it is too strong or misused. Mechanical exfoliants do not have a risk of long term effects or burns. Cosmiko has never incorporated plastic microbeads, often used as mechanical exfoliants, and which are being banned in Europe due to their effect on the environment. At Cosmiko we only use natural exfoliants such as pumice and we recommend our stronger chemical exfoliants are only used by professionals.
