Collagen is everywhere-in our skin, joints, and connective tissues. It’s also trending in powders, gummies, and drinks that promise improving skin, joint health, and fewer signs of aging. But a big question remains: can collagen cause acne?

Short answer: there’s no solid clinical evidence that collagen peptides directly trigger acne. Breakouts arise from a different pathway, and most studies find oral collagen safe with minimal side effects. What matters more are your skin biology, your skincare routine, your balanced diet. The additional ingredients that ride along with some products.

Collagen is the body’s most abundant protein and a core component of connective tissue in skin, bones, tendons, ligaments, and blood vessels. It plays an important role in strength, elasticity, and structure throughout the body. As we age, collagen production declines, which can affect skin appearance, joint comfort, and recovery. This guide explains collagen synthesis, types, potential benefits of oral collagen supplements, how to choose products, and smart ways to support collagen production with a balanced diet.
