Does it really work? Vitamin D is an essential nutrient that performs lots of vital functions. In addition to normal hormonal and glandular activity, the nerve chemical is known as substance P also stimulates more sebum when the body is under pressure or attack.
Zinc can break down or deactivate this chemical peptide the eliminate the over-abundance of oil. Combined with alpha and beta hydroxy acids AHA and BHA , zinc can also slough off residual skin cells from dried sebum and curtail overly active sebaceous glands.
Importantly, zinc also plays a central role in apoptosis natural cell death and renewal at the end of the cellular life cycle. Without zinc, normal apoptosis fails to occur, leading to the unnatural buildup of dying cells. Zinc helps to stabilize this normal cell life cycle, particularly during stages of rapid growth. Because the hormonal activity of the adrenal glands and oil production of the sebaceous glands increase naturally during puberty, use of topical or dietary zinc is a common treatment for pubescent acne.
Antibacterial Benefits Studies have shown that zinc can kill the bacteria known as Cutibacterium acnes or Propionibacterium acnes that invade pores and cause acne. Zinc can also prevent the reproduction or growth of latent bacteria. Importantly, most bacteria and fungi cannot develop resistant strains to zinc because it is a mineral element rather than a chemical antibiotic.
For example, a study in the European Journal of Dermatology found that the most common acne-causing bacteria had developed a resistance to erythromycin an antibiotic used to clear breakouts.
However, the use of zinc lowered resistance to these treatments. In this way, zinc can help clear breakouts in people with antibiotic-resistant skin. Because zinc does not negatively affect digestive gut flora, many health professionals consider the mineral a safer alternative to antibiotics which can inadvertently destroy healthy intestinal bacteria.

While steroids may lower swelling and inflammation for emergencies and the most severe forms of bacterial acne, too many steroids can cause problems with blood pressure and digestive health. Zinc is naturally antimicrobial and can gradually kill off acne-causing bacteria with fewer potential side effects.
Zinc also helps proteins within the body convert vitamin A into a usable form known as retinol. Research has shown that retinol-A compounds can kill acne-causing bacteria and prevent the growth of several types of organisms in clogged skin pores.
Retinol can also help repair lesions or scars that result from repeated breakouts. Zinc boosts the effectiveness of topical retinol treatments, and it can also transport stored vitamin A from the liver. Similarly, zinc helps boost the absorption and transport of vitamin E, a fat-soluble nutrient that has healing properties for the skin. Dermatologists may combine treatments of zinc, vitamin E, and selenium to repair damaged cell membranes or inflamed sebaceous glands.
The mineral zinc can also help expand the growth of white blood cells that fight invasive organisms and prevent pores from becoming infected.
A study in the Journal of Clinical Aesthetic Dermatology found that oral zinc supplements may lower inflammation and limit the pervasiveness of bacteria that causes acne.
Topical zinc may also subdue surface irritation and acne scars. Cystic acne — Breakouts that include sac-like pockets that may be filled with pus or other substances. Pustules — Red, swollen, and eruptive form of acne that often contains yellow pus.
Pustules are usually painful to the touch. If picked or squeezed, pustules can lead to acne scars or permanent hyperpigmentation on the skin. Melasma — Patches of skin discoloration or hyperpigmentation often due to hormonal changes. Rosacea — Skin disease that causes extreme redness, visible blood vessels, and pink, pus-filled eruptions on the face. Comedones — Follicular blockages in which pores or hair follicles become packed with dead skin, sebum, or makeup.
