While serums will not completely remove acne scars, they can help gradually reduce their appearance over time. Retinol is derived from vitamin A and is excellent for increasing collagen production to smooth the skin and create a more even skin texture and tone. Retinol can be prescribed by a dermatologist as tretinoin or found over the counter in various serums or creams. As retinol makes the skin sensitive to the sun, it is essential only to use retinol at night and practice proper sun protection by using a broad-spectrum sunscreen with a minimum SPF of 50.
Dark spots and discoloration that may be left on the skin after an acne lesion or breakout has healed are known as post-inflammatory hyperpigmentation (PIH). Post-inflammatory hyperpigmentation is not true acne scarring and typically resolves independently over time. However, it can take months or even years to diminish without intervention. Targeted over-the-counter skincare products, such as brightening serums, can help accelerate the process and create a more even skin tone. Serums containing active ingredients like vitamin C, azelaic acid, or alpha hydroxy acids (AHAs), such as glycolic acid and lactic acid, are great topical options for reducing post-inflammatory hyperpigmentation. Vitamin C increases cell turnover and has powerful antioxidant properties to slough off pigmented skin cells and brighten skin tone. Alpha hydroxy acids exfoliate discolored skin cells to reveal healthy, even-toned skin cells. Azelaic acid inhibits the activity of enzymes involved with melanin production.
