Smile lines are not caused by dryness alone, so even the best serums for smile lines cannot erase every crease. Yet well-chosen formulas can soften their appearance by supporting hydration, surface smoothness, and firmer-looking skin.
The products in this roundup span retinol, peptides, PDRN, and plumping ingredients, with different formats and strengths. Keep reading to compare what each option is designed to do and which specifications deserve your attention.
Key Takeaways
- Choose a serum with retinol or retinal if your priority is improving the look of persistent lines over time.
- Prioritize hyaluronic acid and glycerin when dehydration makes smile lines appear deeper or more pronounced.
- Check the ingredient concentration and packaging, since unstable actives can lose effectiveness after repeated air and light exposure.
- Select a lightweight serum for daytime use, while richer formulas or retinoid products may suit an evening routine.
- Consider the container size and dose format, especially for concentrated capsules, patches, or eye-area products that may require precise application.

RoC Retinol Wrinkle Filler
For pronounced smile lines and other deep wrinkles, this RoC formula is the strongest fit in the roundup. Its combination of retinol and hyaluronic acid targets the look of lines while adding a moisture-focused ingredient to the formula.
The wrinkle-filler format makes it suited to focused application around the mouth, rather than broad all-over use. Retinol can be drying or irritating for some skin, so introduce it gradually and use daytime sun protection. Its main limitation is that the title does not provide a concentration or detailed usage directions.
- Brand:RoC
- Product Type:Wrinkle filler
- Key Ingredient:Retinol
- Skin Area:Face
- Additional Feature:Hyaluronic acid included
- Additional Feature:Designed for deep wrinkles
- Additional Feature:Focused wrinkle-filler format
-
RoC Forehead Wrinkle Patches
Choose these for a targeted forehead treatment rather than a traditional serum. The patches include hyaluronic acid and are designed to sit directly over a specific wrinkle area, which can make application more precise and less messy.
The six-piece count supports occasional, focused use, especially before an event or as part of a scheduled routine. However, forehead patches are not a direct match for smile lines, and the title does not indicate a retinol concentration or broader facial coverage.
- Brand:RoC
- Product Type:Wrinkle patches
- Key Ingredient:Hyaluronic acid
- Skin Area:Forehead
- Count:6 patches
- Additional Feature:Patch-based application
- Additional Feature:Designed for forehead wrinkles
- Additional Feature:Six patches per package
-
No7 Instant Wrinkle Filler Serum
No7’s formula is a sensible choice if you want a serum texture with an instant wrinkle-filler positioning. It is aimed at softening the visible look of lines, making it particularly appealing for makeup preparation or occasions when surface smoothness matters.
The one-ounce size is practical for regular facial use, and the product is clearly labeled as a face serum. Its limitation is that the title does not identify the key active ingredients, so you cannot assess a specific retinol, peptide, or acid strategy from the available information.
- Brand:No7
- Product Type:Face serum
- Size:1 fl oz
- Skin Area:Face
- Additional Feature:Designed for wrinkle appearance
- Additional Feature:Suitable for facial application
- Additional Feature:Instant-finish focus
-
Abib PDRN Volume Booster
This Abib booster is built for shoppers seeking a multi-active formula for smile lines, the forehead, and the neck. Its listed combination of PDRN, peptides, and retinal gives the product a broader anti-aging profile than a single-ingredient serum.
The 15,000 ppm PDRN claim and 1.01-fluid-ounce tube are clearly stated, while the cream format may suit anyone who prefers richer application around drier-looking lines. Because it contains retinal, sensitivity and dryness are possible, and the title does not explain the ingredient percentages for the peptides or retinal.
- Brand:Abib
- Product Type:Booster cream
- Size:1.01 fl oz
- Key Ingredient:PDRN
- Skin Area:Face and neck
- Additional Feature:15,000 ppm PDRN
- Additional Feature:Peptides included
- Additional Feature:Retinal included
-
RoC Retinol Night Serum Capsules
These capsules suit a nighttime retinol routine with individually portioned applications. The capsule format can help keep each use consistent, while the anti-aging wrinkle serum positioning focuses the product on visible line care.
With 30 capsules in the package, the supply is easy to organize as a month-long routine if used once nightly. The limitation is that single-use capsules may create more packaging waste than a pump bottle, and the title does not state the retinol strength or capsule material.
- Brand:RoC
- Product Type:Night serum
- Key Ingredient:Retinol
- Skin Area:Face
- Count:30 capsules
- Additional Feature:Single-use capsule format
- Additional Feature:Designed for nighttime use
- Additional Feature:Wrinkle-focused formula
-
The Ordinary Argireline Solution
The Ordinary’s serum centers on Argireline 10%, giving you a clearly identified active rather than an unspecified anti-aging blend. It is a good fit for shoppers who want a lightweight, ingredient-focused product aimed at the appearance of fine lines.
The one-ounce bottle offers a standard facial-serum size, and the formula can be directed toward areas such as smile lines. Its limitation is that Argireline is not a substitute for a complete moisturizer or sunscreen routine, and the product title does not promise correction of deep, established wrinkles.
- Brand:The Ordinary
- Product Type:Facial serum
- Size:1 fl oz
- Key Ingredient:Argireline
- Skin Area:Face
- Additional Feature:10% Argireline solution
- Additional Feature:Ingredient-focused formula
- Additional Feature:Fine-line appearance support
-
No7 Line Correcting Booster
No7’s booster serum is best for shoppers who want a compact treatment product aimed specifically at line correction. The booster format suggests a concentrated step that can be added to a broader skincare routine, especially around areas with visible smile lines.
Its 15 ml size works well for targeted application, where only a small amount may be needed per use. The tradeoff is the smaller volume compared with several full-size serums, and the available title does not identify the active ingredients or their concentrations.
- Brand:No7
- Product Type:Booster serum
- Size:15 ml
- Skin Area:Face
- Additional Feature:Designed for line correction
- Additional Feature:Suitable for targeted use
- Additional Feature:Compact treatment format
-
medicube NAD EGF Firming Serum
This medicube serum is a fit if your routine includes both the face and neck, not just the smile-line area. The formula highlights NAD and EGF, two named ingredients, alongside a firming-focused product concept.
Its broad application area makes it useful for anyone building one serum step across multiple regions. Still, the title gives no size, ingredient concentration, or texture details, so you have less information for comparing dosage and value with the other options.
- Brand:medicube
- Product Type:Firming serum
- Key Ingredient:NAD and EGF
- Skin Area:Face and neck
- Additional Feature:NAD-focused formula
- Additional Feature:EGF included
- Additional Feature:Intended for neck use
-
LIBERYEW PDRN Eye Roll-On
The roll-on design makes this LIBERYEW serum the most specialized pick for eye-area application. It contains PDRN and comes as a two-piece set, so it may appeal if you want a portable, precision-focused product rather than a standard dropper serum.
Each container holds 10 ml, for 20 ml across the duo, and the pink volume positioning connects the product to a plumper-looking finish. Its biggest limitation for this roundup is coverage: an eye roll-on is not designed as a primary treatment for broad smile lines.
- Brand:LIBERYEW
- Product Type:Eye roll-on serum
- Size:2 x 10 ml
- Key Ingredient:PDRN
- Skin Area:Eye area
- Count:2 roll-ons
- Additional Feature:Pink volume positioning
- Additional Feature:Portable application format
- Additional Feature:Designed for eye area
-
Volufiline Plumping Face Serum
This serum is designed for shoppers focused on plumping the look of specific areas, including the eye area, cheeks, and smile lines. Its formula lists Volufiline 92% and Pal-Isoleucine 1%, giving you unusually specific ingredient percentages for a product in this category.
The 60 ml size is generous for targeted application, and the lightweight, fast-absorbing positioning may suit layered routines. The limitation is that “plumping” describes a cosmetic appearance goal, not guaranteed structural correction, and the high listed Volufiline percentage should not be treated as a promise of wrinkle removal.
- Brand:Volufiline
- Product Type:Face serum
- Size:60 ml
- Key Ingredient:Volufiline
- Skin Area:Face and eye area
- Additional Feature:Volufiline 92%
- Additional Feature:Pal-Isoleucine 1%
- Additional Feature:Fast-absorbing positioning
Frequently Asked Questions
Can A Serum Remove Smile Lines?
No serum can permanently remove established smile lines, but the right formula can make them look softer, smoother, and less noticeable. Hydrators create a temporary plumping effect, while retinoids may support gradual changes in skin texture with consistent use. Expect visible improvement to take several weeks to a few months, depending on the active ingredient, skin condition, and daily sun protection. Deeper folds may require professional options for a larger change.
Which Ingredients Work Best For Smile Lines?
Retinoids have some of the strongest support for fine lines because they encourage skin renewal and collagen production. Peptides, vitamin C, niacinamide, and hydrating ingredients such as hyaluronic acid can complement them by supporting smoother-looking, more comfortable skin. No single ingredient suits every complexion. Choose based on your tolerance, routine, and primary concern, then use sunscreen every morning to protect the results.
Should You Use Retinol Around The Mouth?
You can use retinol around the mouth if your skin tolerates it, but apply a small amount and avoid the lip edges, corners, and any irritated areas. Begin two or three nights per week, then increase gradually rather than applying it nightly from the start. Use moisturizer before or after retinol if dryness develops. Stop and simplify your routine if you experience persistent burning, swelling, or cracking, and follow medical guidance if you are pregnant, nursing, or managing a skin condition.
Can You Layer Smile-Line Serums?
Layering is possible, but combining too many actives can cause irritation without improving results. A practical pairing is a hydrating serum with a moisturizer, while retinol, exfoliating acids, and strong vitamin C formulas may be better separated by time of day or alternate nights. Apply products from thinnest to thickest texture, and introduce one new active at a time. That approach makes it easier to identify what helps and what leaves your skin cross-examining every decision.
How Long Does A Smile-Line Serum Take To Work?
Hydration can make lines look temporarily smoother within days or weeks, while retinoids and collagen-supporting ingredients usually require eight to twelve weeks of consistent use. Results vary with age, sun exposure, genetics, and how deeply the lines are etched. Apply the serum as directed, moisturize regularly, and use broad-spectrum sunscreen daily. If the product causes ongoing irritation, reduce frequency or discontinue it, since a calm skin barrier is part of the result.
