Daily broad-spectrum sunscreen plus a prescription retinoid is the best-evidenced routine for reducing facial wrinkles, with in-office procedures reserved for deeper lines.
Two habits do most of the work: blocking ultraviolet light every day and using a retinoid long enough for collagen remodeling to show. Everything else — moisturizer, peels, injectables, lasers — plays a smaller, specific role. Dermatologists split wrinkles into two camps: lines etched by sun damage and lines carved by repeated muscle movement. Each responds to different tools, and mixing them up wastes money.
What Actually Reduces Wrinkles, Ranked by Evidence
Sun protection and topical tretinoin carry the strongest clinical backing; moisturizers, injectables, and resurfacing procedures address narrower problems. The American Academy of Dermatology lists all as legitimate treatments, but the research weight varies sharply.
- Daily sun protection. UV drives photoaging, so unprotected skin undoes whatever else you apply. The AAD recommends sunscreen every day — overcast, cold, or indoors near windows — and stopping tanning beds entirely.
- Prescription tretinoin. A 2025 systematic review and meta-analysis pooled 8 randomized trials covering 1,361 patients, with follow-up from 16 weeks to 2 years. Tretinoin significantly improved both fine and coarse photodamage wrinkles versus a placebo vehicle.
- Moisturizer. Hydration plumps the surface and temporarily softens fine lines. It does not restructure collagen, so don’t expect it to erase anything deep.
- Botulinum toxin. OnabotulinumtoxinA is FDA-labeled for temporary improvement of moderate-to-severe glabellar lines, lateral canthal lines, and forehead lines in adults — dynamic creases that form when muscles contract.
- Dermatologist procedures. Fillers, chemical peels, microdermabrasion, and laser resurfacing target volume loss, surface texture, or etched lines creams can’t reach.
One nuance before you buy a serum: the FDA label for tretinoin cream 0.02% reviewed five controlled trials (324 tretinoin-treated, 332 vehicle-treated patients, 24 weeks) and found adequate evidence for improving fine facial wrinkling in only two of the five — with insufficient evidence for coarse wrinkling, mottled pigmentation, roughness, or laxity. In plain terms, tretinoin reliably helps fine lines; coarse wrinkles often need more than a cream. The AAD’s guide to treating wrinkles and sun damage lays out the same layered logic.
How Do You Use Tretinoin Without Quitting?
Start at the lowest concentration, apply a pea-sized amount at night, and build tolerance gradually — irritation is the main reason people abandon retinoids before results appear. Reviewed studies used concentrations from 0.025% to 5% over 3 to 24 months, with improvement sometimes appearing as early as one month.
Tretinoin is a U.S. prescription medicine, so formulation, strength, and label instructions come from your clinician — not from assumptions that all tretinoin products work identically. Two non-negotiables: apply to dry skin to limit stinging, and wear sunscreen daily, since UV can trigger side effects and cancel out gains.

Which Treatment Fits Which Wrinkle Type?
Matching treatment to wrinkle is the biggest predictor of satisfaction. Dynamic lines respond to neuromodulators; sun-etched fine lines to retinoids; volume loss and deep folds to fillers and resurfacing.
| Wrinkle Type | Best-Fit Treatment | Realistic Expectation |
|---|---|---|
| Fine lines from sun damage | Daily sunscreen + prescription tretinoin | Measurable softening over months |
| Coarse photodamage wrinkles | Tretinoin, often plus a procedure | Partial improvement, rarely full erasure |
| Forehead and frown lines | OnabotulinumtoxinA injections | Temporary smoothing, repeat visits needed |
| Deep folds and volume loss | Dermal fillers | Plumping that fades over time |
| Rough surface texture | Chemical peel or laser resurfacing | Resurfacing with real downtime |
| Dry, crepey surface | Moisturizer | Temporary visual smoothing only |
Injectables carry cautions. The onabotulinumtoxinA label warns against injecting inflamed areas and notes care around existing ptosis or excessive weakness in targeted muscles. Glabellar dosing runs 20 Units total across five intramuscular sites — this is a medical procedure, not a spa impulse. All injectables and resurfacing should be done by a qualified professional after evaluating your skin type, medications, and history.
What Should You Do First?
Build the foundation first: sunscreen every morning, a retinoid at night if tolerated, and a moisturizer to keep the barrier intact. Give it three to six months — trial data measured results in months, not days. If dynamic lines or volume loss still bother you, a dermatology consult sorts out which procedure matches your wrinkle type. No treatment permanently erases wrinkles, and anyone promising that is selling something the evidence doesn’t support.
Common Questions
Can moisturizer actually get rid of deep wrinkles?
No. Moisturizer hydrates the outer layer and temporarily softens fine lines, which is why skin looks smoother right after application. It does not rebuild collagen or change skin structure, so deep wrinkles and folds stay put. It’s a supporting player alongside sun protection and retinoids, not a standalone fix.
How long before tretinoin shows results?
Reviewed studies reported improvement as early as one month, with continued gains through 24 months. Most people need several months of consistent nightly application before change is obvious, and early irritation is common. Gradual introduction at a low strength, per your prescriber’s instructions, keeps you on track long enough to benefit.
Are injections a permanent fix for forehead lines?
No. OnabotulinumtoxinA is FDA-labeled for temporary improvement of moderate-to-severe forehead lines, glabellar lines, and crow’s feet in adults, so smoothing fades and repeat treatments are needed. It also targets only muscle-driven dynamic lines — sun-etched wrinkles and volume loss need different approaches.
