Exfoliation is the process of removing dead skin cells from the surface of your skin using a chemical, granular substance, or exfoliation tool. There are two types of exfoliation: physical and chemical. Physical exfoliation involves using a product or tool that requires manual scrubbing or rubbing, such as cleansing scrubs, body brushes, and loofahs. Chemical exfoliation involves using acids or enzymes to dissolve away either the ‘glue’ that holds skin cells together or the actual skin cell itself.
Exfoliating is beneficial in removing dead skin cells and maintaining the appearance of healthy skin. However, over-exfoliating and certain chemical exfoliants can irritate the skin if done incorrectly. Therefore, it is important to choose the right exfoliating method and ingredients for your skin type and concerns.
Here are some positive and negative aspects of exfoliation:
Positive:
- Removes dead skin cells and build-up from the outer layer of skin, revealing fresher, healthier skin underneath.
- Prevents clogged pores and breakouts.
- Allows for cell turnover, which is important for protecting the skin and assisting in the anti-aging process.
Negative:
- Physical exfoliation can sometimes irritate the skin and may result in transepidermal water loss.
- Chemical exfoliation can irritate the skin if done incorrectly.
Ingredients or materials:
- Abrasive materials for physical exfoliation include cleansing scrubs, exfoliating mitts, dry brushes, loofahs, pumice stones, and microdermabrasion treatments.
- Gentle exfoliating ingredients for chemical exfoliation include glycolic acid, lactic acid, and salicylic acid.
- Natural exfoliants for mechanical exfoliation include sugar, oatmeal, and sponges.
