The skin is our largest organ and also our protection against a lot of diseases apart from the vital role it has in our appearance. Hence it needs a much more regular care than any other organ. Exfoliation is very important in keeping our skin healthy and disease free.
Some products can be used anywhere on the body whereas there are certain products meant for problematic areas like feet and some are for gentle areas like the face and neck.
There are mainly two types of exfoliators - mechanical and chemical.
Mechanical exfoliators have tiny microscopic clenches which help to remove dead cells by scrubbing with them either by applying directly on to the skin or by using a loofah along with it. Common ones contain small pieces of apricot pits or walnut shells and are mainly used for feet to keep it soft and supple. Others for use except on face and neck are commonly referred to as body scrubs commonly have tiny particles almond shells or cosmetic shells. Those who have time can also make some wonderful scrubs at home using dried orange peel and a lot of other ideas which are freely available on the net. They are available over the counter in all shops selling beauty products in the form of creams and gels.
Chemical exfoliators work in the same way as the mechanical ones except for the fact they use mild acids in place of the grit or granules in the latter type. The common acids used are alpha hydroxyl, beta-hydroxyl and salicylic which are all skin friendly.
Choose your product according to your skin type; for example, for normal to oily skin lactic acid or alpha hydroxyl acid based products is recommended. Some allergic or sensitive skins may however experience itchiness and rashes so always test on a small area first before using any exfoliating product. However there are some products specifically for sensitive skin with contents like aloe-Vera, green tea and papaya etc but it is always advisable to do a small test.
