Fine lines are a completely normal part of getting older, but that doesn’t mean you can’t give your skin a little extra support along the way. While a consistent skincare routine, daily sunscreen, a balanced diet, and healthy lifestyle habits all play important roles in how your skin looks and feels, certain supplements may also help support smoother, healthier-looking skin from the inside out.
Of course, no supplement is going to erase wrinkles overnight—and any benefits tend to appear gradually with consistent use. But some nutrients have research behind them for supporting collagen production, hydration, elasticity, and the skin’s ability to protect itself from everyday stressors. Here are three skin-supporting supplements that may be worth considering if softening the appearance of fine lines over time is one of your goals.

1. Fish Oil
Fish oil is rich in omega-3 fatty acids, particularly EPA and DHA, which can help support the skin’s natural barrier and its ability to hold onto moisture. Because omega-3s also have anti-inflammatory properties, getting enough of these healthy fats may help keep skin looking calm, supple, and healthy. While fish oil isn’t a wrinkle eraser, supporting hydration and barrier function can help give dry or mature skin a smoother, plumper appearance that may make fine lines look less noticeable.

2. Collagen
Collagen is one of the proteins responsible for giving skin its structure, firmness, and elasticity, but the body’s natural collagen production declines with age. Research suggests that regularly taking hydrolyzed collagen peptides may modestly improve skin hydration and elasticity and reduce the appearance of wrinkles over time. Think of collagen supplements as a long-game addition rather than an instant fix: when they do provide visible benefits, they typically require consistent use for several weeks or months.

3. Vitamin C
Vitamin C is especially important for skin because your body needs it to synthesize collagen in the first place. It’s also a powerful antioxidant that helps protect cells against oxidative stress caused by factors such as UV exposure and pollution, which contribute to visible skin aging. Getting enough vitamin C through food and supplements (when needed) can support the processes that help skin maintain its firmness and resilience, although taking more than your body needs won’t necessarily translate into younger-looking skin.
