It unclogs pores & prevents acne
Accumulation of dead skin cells and debris seals your pores, so when sebaceous glands produce oil, it gets "stuck" under the dry skin. This causes breakouts, whiteheads and blackheads because there is nowhere for the oil to go.
When you exfoliate your skin, you're effectively unclogging your pores, sweeping away dry skin and other debris that might remain on your skin after cleansing. This stops it from clogging your pores which effectively prevents the formation of whiteheads, blackheads and acne.
It evens skin tone & lightens dark spots
Often, the real concern is not so much the actual blemishes, but rather the red, dark marks that remain on the skin long after the breakout has healed.
The key to fading those post-breakout marks is to increase your exfoliation. The more you remove the surface damaged cells, the more you are ridding the skin of the dark marks and encouraging the formation of new healthy (non-scarred) skin cells. The result is more even-toned skin with less scarring.
It improves the appearance of ageing skin
The skin's natural exfoliation process slows as the skin ages, resulting in an accumulation of dry skin cells.
Regular exfoliation helps to stimulate collage synthesis to improve the skin's texture, integrity and keep the skin looking plump, tight and young.
This means that exfoliating can actually offer a ton of anti-aging benefits, effectively helping to lessen the appearance of fine lines and wrinkles resulting in that ultra-dewey and baby-faced complexion we strive for.
