Nasolabial folds — those lines running from the nose to the corners of the mouth — deepen over time as collagen production slows and skin loses its bounce. A targeted serum or cream can plump the skin, fill in the crease, and soften the shadow these lines cast, but choosing the wrong active ingredient wastes time and can irritate sensitive cheek and mouth areas.
I’m Mohammad — the founder and writer behind ProteinJug. I spend my time analyzing ingredient concentrations, delivery systems, and formulation stability across hundreds of anti-aging products to separate marketing claims from real structural improvement.
This guide reviews seven serums and creams specifically selected to address smile lines, ranking them by formulation quality and real-world efficacy. Whether you are looking for a gentle daily moisturizer or a potent retinoid treatment, this is the most practical resource for finding the right products for smile lines.
How To Choose The Best Products For Smile Lines
Smile lines are unique because they sit right at the intersection of skin movement, sun damage, and natural aging. The best treatment delivers hydration to plump the skin, an active to stimulate collagen, and a delivery system that keeps ingredients working without migrating into the mouth or eyes. Every product in this guide was judged on those three criteria.
Active Ingredient Match
Retinol and retinoids are the gold standard for rebuilding collagen, but they irritate the thin skin around the mouth if dosed too high. Niacinamide (vitamin B3) is a gentler alternative that still improves elasticity and fades the shadow of a deep line. Peptides and glycolic acid fill a middle ground — less irritation than retinol but slower results. Match the ingredient to your skin’s tolerance, not just the line’s depth.
Texture and Spreadability
A cream or serum for smile lines must spread easily across a small, curved area without feeling tacky. Heavy waxes or thick silicones can slide into the mouth or pill under makeup. Lightweight gel-creams or serums with fast absorption are preferred for daytime use. Richer creams work better overnight when the product has hours to penetrate undisturbed.
Packaging and Freshness
Smile line products are judged by how long the active stays stable. Vitamin C and retinol oxidize quickly in clear bottles exposed to light. Airless pumps or opaque tubes preserve potency longer than jars that are opened daily. Check the container type — a poorly packaged product loses effectiveness weeks after opening.

In‑Depth Reviews
1. SUNGBOON EDITOR Deep Collagen Retinol Capsule Cream
The SUNGBOON EDITOR capsule cream is the most versatile product in this list because it combines low-molecular collagen, retinol, and micro-sized spicules into a single customizable formula. The transparent gel base includes eight types of hyaluronic acid and panthenol for layered hydration. The spicules provide gentle stimulation that helps the conditioning ingredients penetrate deeper around the nasolabial fold without the stinging associated with clinical microneedling.
Users with dry or stressed skin report a dewy glow within ten days of nightly use, with fine lines around the eyes and smile lines visibly softening. The capsule-to-gel ratio lets you adjust the strength — more capsules for a stronger retinol effect on deeper folds, fewer capsules for a lighter maintenance dose. The packaging is compact and the mixing spoon keeps application hygienic. No irritation or greasiness was noted across multiple review cycles.
The cream absorbs quickly and layers well under sunscreen or makeup. Some users with extremely reactive skin may need to start with a lower capsule ratio to build tolerance. The texture is lightweight but richer than a standard serum, making it suitable as a standalone overnight treatment. For a mid-range price, it delivers a clinical-style collagen boost without a prescription.
Why it’s great
- Adjustable retinol strength via capsule ratio reduces irritation risk
- Micro-sized spicules boost ingredient absorption into deeper skin layers
- Eight types of hyaluronic acid provide lasting hydration without greasiness
Good to know
- Mixing capsules into the gel adds an extra step to the routine
- Some users may feel mild tingling from the spicules on first application
2. TruSkin Vitamin C Serum
TruSkin uses Sodium Ascorbyl Phosphate, a highly stable form of vitamin C that maintains potency longer than L-ascorbic acid. This is critical for smile lines because the product stays active through months of daily use without turning yellow or oxidizing in the dropper bottle. The serum layers vitamin C with hyaluronic acid, vitamin E, aloe vera, and jojoba oil to support the skin barrier while brightening the shadow cast by deep nasolabial folds.
Multiple users with sensitive skin report no redness or dryness, which is unusual for a vitamin C product. The unscented formula works well on non-Caucasian skin tones and fades dark spots around the mouth area within a few weeks. The dropper bottle is a minor frustration — some users prefer a pump to prevent air exposure — but the product itself delivers visible brightening and a smoother texture around the smile line zone.
For about two ounces, this serum offers a generous volume compared to standard one-ounce serums. It is dermatologist and clinically tested, cruelty-free, and free from parabens and dyes. The formula is not heavy enough to replace a moisturizer, so you will need to layer it under a cream, but its gentle brightening action makes it ideal for morning use when retinol is too strong.
Why it’s great
- Stable vitamin C form stays effective longer in the bottle
- Hydrating base with aloe and jojoba oil prevents the tightness vitamin C can cause
- Large bottle size offers good value for daily application
Good to know
- Dropper design can introduce air and accelerate oxidation over time
- Results on deep static lines are slower than retinol-based alternatives
3. Eight Saints Original Cin Niacinamide Serum
Eight Saints pairs ten percent niacinamide with hyaluronic acid and aloe vera to create a serum that reduces fine lines without the peeling or purge phase common with retinol. Niacinamide is especially effective for smile lines that appear as shallow creases rather than deep-set folds — it improves elasticity and evens out the complexion so the line is less visible. The formula is fragrance-free and carries an EWG 1 rating for safety, which matters when applying near the mouth where product can migrate.
Users consistently note that the serum smooths skin texture and reduces pore visibility around the nose and cheek area. The lightweight gel spreads easily over the nasolabial fold and absorbs in seconds, leaving a non-sticky finish that works well as a primer under makeup. Several reviewers switched from prescription retinoids to this serum because it provides visible results without the irritation they experienced on their cheek and mouth skin.
The one-ounce bottle lasts about three months with daily single-pump use. The pump mechanism is hygienic and prevents contamination. For an entry-level active serum targeting smile lines, this product offers the gentlest entry point with no downtime. It pairs well with the Eight Saints retinol serum in the evening and a vitamin C serum in the morning for a complete anti-aging routine.
Why it’s great
- 10% niacinamide reduces fine lines without irritation or purging
- Fragrance-free formula keeps the product safe for the sensitive mouth area
- Lightweight texture layers easily under moisturizer and makeup
Good to know
- Deep-set nasolabial folds may need a stronger active for full correction
- The gel can feel goopy if you apply too much before it dries
4. DIME Beauty Dewy Day Cream
DIME Beauty’s Dewy Day Cream is built for dry and combination skin that needs multi-layered hydration without heaviness. Smile lines look more prominent when the surrounding skin is dehydrated, and this cream addresses that by combining rosehip seed oil, ceramide 3, tremella snow mushroom, and squalane into a lightweight daily moisturizer. The ceramide complex strengthens the skin barrier, which is often compromised around the nose and mouth from frequent wiping and product application.
Reviewers with dry, flaky skin around the nasolabial area report that the cream reduces flakes and breakouts after a single use. The texture is non-greasy and non-comedogenic, making it safe for acne-prone skin. A single tub lasts about three months with twice-daily application. The cream works best when applied after a hyaluronic acid serum — the multi-layered hydration plumps the skin, softening the appearance of smile lines over time.
DIME Beauty commits to clean ingredients with a safe EWG rating across every component. The cream is vegan, cruelty-free, and free of parabens, sulfates, phthalates, and artificial fragrances. It does not contain a high concentration of retinol or peptides, so it is best used as a hydrating base layer rather than a standalone anti-aging treatment. For users who struggle with dehydration lines, this cream is a practical first step before adding active serums.
Why it’s great
- Ceramide-rich formula strengthens the skin barrier around the mouth
- Lightweight, non-greasy texture works under makeup without pilling
- Free of artificial fragrances and safe for sensitive skin
Good to know
- Not a standalone treatment for deep static smile lines
- Tub packaging exposes the cream to air and contaminants each use
5. MAELOVE Hydrator Hyaluronic Acid B5 Serum
MAELOVE’s serum delivers an immediate plumping effect that is ideal for smile lines because it fills the crease from the inside out. The formula combines hyaluronic acid with resveratrol, a super-antioxidant that supports skin rejuvenation, and vitamin B5 for nourishment. The oil-free gel texture absorbs in seconds and leaves a dewy glow without stickiness — a rare combination for a hyaluronic acid product.
Multiple users describe the effect as “glass skin” — a smooth, reflective surface that makes fine lines less noticeable. The serum layers well under moisturizer and makeup without pilling. Over time, the antioxidant support from resveratrol helps protect the skin around the nasolabial fold from environmental stress that accelerates aging. The formula is vegan, cruelty-free, and free of parabens, phthalates, and synthetic dyes.
The one-ounce bottle is small but concentrated — a little serum goes a long way. Users with dry or aging skin report that the immediate plumping lasts through the day when paired with a good moisturizer. This product is best positioned as the hydrating step in a retinol or vitamin C routine. It will not rebuild collagen on its own, but it makes existing lines look shallower within minutes of application.
Why it’s great
- Instant plumping effect makes smile lines visibly shallower after application
- Oil-free gel texture absorbs quickly without stickiness or greasiness
- Resveratrol provides antioxidant protection for the delicate mouth area
Good to know
- Does not stimulate collagen production; results are temporary hydration
- Small bottle size requires careful usage to avoid running out
6. goPure Glyco-Peptide Anti Wrinkle Face Cream
goPure’s Glyco-Peptide cream targets the structural component of smile lines with a proprietary blend of Solumoist, Dermaxyl, and Matrixyl — peptide complexes that signal the skin to produce collagen and fill wrinkles from within. Glycolic acid provides mild exfoliation to smooth the surface texture, while ceramides and niacinamide support the skin barrier. This multi-angle approach makes it one of the most effective non-retinol options for deep nasolabial folds.
Users report visible differences in skin smoothness and softness within two weeks of consistent use. The cream is rich but non-greasy, absorbing quickly without leaving a film. It works well as a night treatment when the skin has hours to absorb the peptides. The formula is science-backed and clinically tested, with natural botanicals at active levels. Some users with very deep static lines find the results slower than prescription retinol, but without the irritation or peeling.
The 1.7-ounce glass jar is small but concentrated — a little product covers the entire face. The jar packaging is less hygienic than a pump, but the cream’s consistency prevents contamination when used with clean hands. For a premium-peptide cream at a mid-range price, this product offers a strong alternative for anyone who cannot tolerate retinol but still wants collagen stimulation around the mouth.
Why it’s great
- Matrixyl and Dermaxyl peptides actively signal collagen rebuilding in deep lines
- Glycolic acid exfoliates surface texture for smoother skin around the mouth
- Rich formula absorbs quickly without greasiness
Good to know
- Deep static nasolabial folds may take longer to show improvement
- Glass jar packaging exposes the product to air and bacteria
7. Eight Saints Retinol Skin Care Serum
Eight Saints formulates a retinol serum that balances efficacy with gentleness, making it a strong choice for smile line treatment without the harsh downtime often associated with retinoids. The formula combines retinol with hyaluronic acid to pull moisture into the skin and green tea extract to calm redness and irritation. This is especially important around the mouth, where the skin is thinner and more reactive than the forehead or cheeks.
Users with sensitive skin who previously experienced peeling from other retinol serums report that this one causes no dryness or irritation even when used three times per week. The lightweight, scent-free serum absorbs immediately and leaves no greasy residue. After two weeks, reviewers note smoother skin, reduced fine lines, and a more even skin tone around the nasolabial area. The hyaluronic acid keeps the skin hydrated, so there is no tightness after application.
The one-ounce bottle comes with a dropper for controlled application. The pump-less design is less ideal for preventing oxidation, but users report the serum maintains potency through several months of use when stored away from direct sunlight. This is a strong entry-level retinol for anyone who has avoided retinol because of past irritation. It pairs perfectly with the Eight Saints niacinamide serum for a complete day-and-night smile line routine.
Why it’s great
- Retinol paired with hyaluronic acid prevents the drying effect common with retinoids
- Green tea extract calms redness and reduces irritation around the mouth area
- Lightweight, fragrance-free formula absorbs quickly without greasiness
Good to know
- Dropper bottle can introduce air and reduce retinol potency over time
- Deep-set nasolabial folds may need a higher retinol percentage for maximum effect
