Topical vitamin C serum: "Vitamin C serums block abnormal pigment production and can brighten spots that have already developed," says Dr. Zeichner. "They can be layered underneath your sunscreen in the morning." These serums can also help build collagen and promote healing, says says Dr. Shah, who suggests trying "SkinCeuticals C E Ferulic to do the trick.
According to dermatologist Dr. Whitney Bowe, some scars are thick, raised hypertrophic scars that stick out above the skin; others are keloid, which are scars that have over-healed, and manifest as dense, rubbery skin tissue. Then, there are atrophic scars that appear as depressions in the skin — they're the most challenging to treat. The three main categories of atrophic scars are:
Your doctor might recommend an injectable treatment called a filler. "Mainly, I treat acne scars with hyaluronic acid fillers, such as Restylane, but not all acne scars respond to this sort of treatment," Schlessinger says. "Additionally, I personally find that Accutane has a remarkable effect on acne scars if it is prescribed early on in the course of a scarring acne."
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.
