Old marks still sticking around take patience and consistency to treat. One way to even out skin tone over time is with regular exfoliating. "[Exfoliating] is important in treating acne scars at home as it lifts dead skin and allows new skin to grow and proliferate," Dr. Moy explains. This exfoliator contains papaya enzymes to break down dead skin cells and microderm crystals to buff away acne scars. Aloe vera, coconut, and vitamins E and B nourish the skin simultaneously.
No one factor causes acne. Acne occurs when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty or due to other hormonal changes. Sebum (oil) is a natural substance that lubricates and protects the skin. Associated with increased oil production is a change in the manner in which the skin cells mature, predisposing them to plug the follicular pore. The plug can appear as a whitehead if it is covered by a thin layer of skin, or if exposed to the air, the darker exposed portion of the plug is called a "blackhead." The plugged hair follicle gradually enlarges, producing a bump. As the follicle enlarges, the wall may rupture, allowing irritating substances and normal skin bacteria access into the deeper layers of the skin, ultimately producing inflammation. Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); if the inflammation is deeper still, it forms a cyst.
