If you’re looking to slow down the signs of aging and keep your skin youthful, neuroscientist Robert Love has some science-backed supplement advice that may help. On his TikTok, Love explains that inflammation is not only a primary risk factor for Alzheimer’s disease but also one of the main drivers of aging—including skin aging. By supporting your body with the right nutrients, you can protect both your brain and your skin.
Here are the three supplements he recommends for reducing wrinkles:
1. Fish Oil
Often associated with brain health, fish oil is also a powerhouse for your skin. Research shows that people who consume high levels of omega-3 fatty acids from fish oil have fewer wrinkles. Its anti-inflammatory properties help maintain skin elasticity and reduce the visible effects of aging.

2. Collagen Peptides
Collagen peptides have recently gone viral in the beauty world—and for good reason. Studies indicate that women who take collagen peptides regularly see benefits for skin, bones, and muscles. For the skin, collagen peptides support firmness and hydration, helping to smooth out fine lines and wrinkles over time.

3. Vitamin C
Vitamin C is essential for new collagen production, making it a must-have for anyone concerned with aging. Love recommends at least 1,000 milligrams per day, preferably in a time-release form, which helps your skin maintain its structural integrity. Collagen is the protein that keeps skin plump and resilient, so vitamin C plays a crucial role in promoting youthful-looking skin.
By incorporating these three supplements into your daily routine—fish oil, collagen peptides, and vitamin C—you can tackle wrinkles from the inside out while also supporting overall health. As Love emphasizes, what’s good for your body and brain is often good for your skin too.
