Oxidative Stress and Acne: Antioxidant Signaling, GHK-Cu and NAD+ Research

Oxidative stress is one of the less obvious pieces of acne biology. It helps explain why inflammation becomes severe and why some research peptides draw attention for antioxidant effects.

What oxidative stress is

Cells constantly produce reactive oxygen species (ROS) as byproducts of metabolism. Normally antioxidant defenses neutralize them. When ROS overwhelm those defenses, they damage lipids, proteins and DNA. That is oxidative stress.

The acne connection

• Squalene, a lipid in sebum, can oxidize into squalene peroxide, which has been linked to inflammation in follicles
• C. acnes growth and immune cells in the lesion release more ROS
• Oxidative damage can amplify the inflammatory signals that produce lesions and marks

Peptides and cofactors studied for antioxidant signaling

GHK-Cu

In experimental systems GHK-Cu has been associated with increased antioxidant enzymes (such as superoxide dismutase) and reduced oxidative damage. See GHK-Cu.

NAD+

NAD+ is a coenzyme that cells use in energy metabolism and in stress-response enzymes. Because cellular defense systems depend on it, it features in research on aging and oxidative stress. See NAD+ 500mg.

A note on caution

Antioxidant effects in a dish do not guarantee benefits in living skin. Too much or too little of a signal can both cause problems, and results vary by model.

The bottom line

Oxidative stress is a real piece of the acne puzzle, and it explains why researchers study peptides and cofactors beyond just inflammation.
