Sagging neck skin and horizontal lines are some of the most stubborn signs of aging, often appearing earlier than expected due to collagen loss, sun exposure, and everyday movement like looking down at phones. But according to Dr. Lim Ing Kien, there are a few standout skincare ingredients that can meaningfully improve the appearance of neck lines by targeting hydration, firmness, and collagen production.
In a recent video, Dr. Lim breaks down three key ingredients that can help smooth and support the delicate skin on the neck over time. Read on to learn more.

Best Ingredients For Neck Lines
First are peptides, which he describes as one of the most important ingredients for aging skin. Peptides act as building blocks that signal the skin to produce more collagen. Since collagen is responsible for keeping skin firm and lifted, increasing its production can help reduce the depth of existing neck lines and improve overall skin elasticity. With consistent use, peptides can help the neck appear firmer and more supported.
The second ingredient is hyaluronic acid, a powerful humectant known for its ability to attract and retain water within the skin. Dr Lim explains that this ingredient helps deeply hydrate the skin, which in turn plumps up fine lines and creases on the neck. Because dryness can make wrinkles look more pronounced, hyaluronic acid plays a key role in creating a smoother, more supple appearance almost immediately after application, while also supporting long-term hydration balance.
Finally, Dr. Lim points to retinol (also known as retinoids) as a gold-standard anti-aging ingredient. Retinol works by increasing cell turnover and encouraging consistent, healthy collagen production over time. This helps refine skin texture, improve tone, and gradually reduce the appearance of more stubborn, deeper-set neck lines. While it can be powerful, dermatologists often recommend introducing retinol slowly, as the neck area can be more sensitive than the face.
The bottom line
Together, these three ingredients—peptides, hyaluronic acid, and retinol—form a dermatologist-approved approach to improving neck aging concerns. While no product can “snap back” sagging skin overnight, consistent use of these actives, paired with sun protection and gentle skincare, can significantly improve the look and feel of the neck over time.
