Retinol vs. peptides for eye wrinkles: which should you use?

Retinol has more evidence for fine lines but can irritate; peptides are thought to be gentler but have less evidence behind them. Around the eyes, put morning sun protection first and start retinol low and slow. Eye-area skin is thought to be thin, so it folds with every blink and reacts fast to anything harsh.

Why does the eye area wrinkle first?

The skin here is thought to be thin with few oil glands, and it creases in the same spots every time you blink, smile, or squint. Because thin skin folds here countless times a day, fine lines tend to show around the eyes earlier than elsewhere. If you are noticing them young, our note on eye fine lines in your 20s walks through the early signs.

Retinol vs. peptides: which is better for eye wrinkles?

They aim at the same goal but work differently. Retinol is thought to support skin and collagen turnover, and it has more evidence for fine lines than peptides. When older people applied retinol to the inner upper arm, fine wrinkling eased and markers of new collagen rose (Kafi et al., 2007). That wasn't tested around the eyes. Retinol can irritate, so on thin eye-area skin start low and go slow. If you are layering it with other actives, our guide on using vitamin C and retinol together helps.

Peptides take a softer route. Palmitoyl peptides and similar ingredients are thought to help signal skin to build collagen. They are thought to be gentler than retinol, so they are easy to use daily. Retinol still carries more evidence, but if irritation worries you, starting with peptides to build tolerance is a smart order. For why collagen drives firmness, see our note on cheek firmness and collagen.

In short: sun protection comes first for eye wrinkles

Around the eyes, put morning sun protection first, and add retinol or peptides at low strength while you watch how your skin responds. The eye area is thin skin that folds countless times a day. Retinol reduced fine wrinkling on older people's inner arms (Kafi et al., 2007), but that wasn't checked around the eyes. Peptides are thought to be gentler, though their evidence is thinner than retinol's. UV is thought to be a major driver of skin aging, so rather than rushing a high strength, keep up daily sun protection.

One thing today

• Around the eyes, start retinol at low strength, two or three nights a week. Even in the arm trial, 0.4% retinol was applied up to three times a week (Kafi et al., 2007). The next morning, check the eye area for redness, flaking, or stinging. If the area swells or stinging lasts several days, stop and see a dermatologist.
• If irritation worries you, keep a peptide as your daily base step. Whether peptides reduce eye wrinkles hasn't been tested in a trial. That evening, check that the eye area isn't stinging or red. If redness and itching continue even with peptides alone, see a dermatologist.
• Whatever you apply, put morning sun protection first. Sun protection is a common baseline, not something tested on eye wrinkles specifically. Check in the mirror that the outer corners and under-eyes aren't missed. If a spot near the eyes is new or keeps changing shape, see a dermatologist.
