Trifarotene (brand name Aklief) is a game-changer for acne treatment because it’s the first topical retinoid ever approved to work on both your face and body. The FDA approved this new molecule on October 4, 2019—the first new retinoid approved for acne in over 20 years. What makes this unique is that previous retinoids like tretinoin and adapalene were proven effective on facial acne, but trifarotene is the only one with clinical evidence showing it actually works on truncal (body) acne too, meaning the chest, shoulders, back, and other areas where stubborn acne often appears. This article covers how trifarotene works differently from other retinoids, what the clinical data actually shows, who benefits most from it, and what side effects you should expect.

How Does Trifarotene Work Differently From Other Retinoids?
Trifarotene’s mechanism is more selective than older retinoids. Instead of activating all three types of retinoic acid receptors in the skin (RAR alpha, beta, and gamma), trifarotene preferentially targets RAR gamma—which happens to be the most common RAR found in skin tissue. This selective targeting is why it can be formulated at a lower concentration (0.005%) while still being effective.
The selectivity also means less systemic absorption and potentially fewer side effects compared to first-generation retinoids like tretinoin, which blast all three receptors and can cause significant irritation, especially early in treatment. For comparison, tretinoin has been the gold standard for acne since the 1980s and works extremely well on facial acne, but it’s rarely used on body acne because of irritation concerns and the difficulty of applying creams consistently over large areas like the back. Adapalene, approved in the late 1990s, is gentler than tretinoin but still wasn’t formally studied for body acne efficacy. Trifarotene changes this equation by being gentle enough for body use while still delivering measurable acne improvement on the trunk—something no other topical retinoid had clinical evidence for before.
What Do the Clinical Trials Actually Show?
Trifarotene’s approval was based on two large phase 3 trials called PERFECT 1 and PERFECT 2, which together enrolled 2,420 patients with moderate acne. The results were consistent across both studies: in PERFECT 1, 29.4% of people using trifarotene achieved significant facial improvement compared to only 19.5% with the placebo vehicle cream. PERFECT 2 showed even stronger results, with 42.3% achieving improvement versus 25.7% with vehicle. The improvement timeline is practical too—facial acne shows visible improvement as early as 2 weeks into treatment, while body acne takes a bit longer at around 4 weeks, which is typical for any acne treatment since the skin cycles take time. However, it’s important to understand what “significant improvement” means in these studies.
The FDA defines this as at least a 2-grade improvement on the acne severity scale, not complete clear skin. Many patients in the trials had remaining mild acne even after the 12-week treatment period. Also, these trials tested once-daily application, which is the standard regimen. If you miss doses or apply inconsistently, results will be slower or less dramatic. The trials also excluded patients younger than 9 years old, so trifarotene is not approved for very young children with acne, and there’s limited data on teenagers versus adults.
Is Trifarotene Better Than Tretinoin or Adapalene?
This is the question dermatologists get asked constantly, and the honest answer is: it depends on where your acne is and how sensitive your skin is. For facial acne alone, tretinoin has decades of proven efficacy and is significantly cheaper because it’s generic. If you have acne only on your face and can tolerate tretinoin’s irritation, tretinoin is still a very solid choice and costs a fraction of what Aklief costs. Adapalene sits in the middle—gentler than tretinoin but not proven for body acne.
The real advantage of trifarotene shows up when you have significant acne on your face AND chest/back/shoulders simultaneously. A patient with facial acne who also breaks out across their shoulders and upper back would normally need to use one retinoid on their face and potentially nothing (or benzoyl peroxide) on their body, or they’d risk severe irritation trying to use tretinoin everywhere. With trifarotene, you can use the same product head to toe, which simplifies the routine and actually treats the full acne problem. For sensitive skin types, trifarotene’s selectivity for RAR gamma also makes it gentler than tretinoin, though not necessarily milder than adapalene.
What Are the Side Effects, and How Long Do They Last?
The most common side effects with trifarotene are application site irritation, itching, and sunburn—and importantly, most of these occur in the first 4 weeks of treatment. This is the adjustment period where your skin is learning to tolerate the retinoid. Some people experience redness, dryness, or mild peeling, especially around the nose and mouth where skin is thinner. The good news is that by week 5 and beyond, tolerance usually improves significantly. Your skin builds up a resistance to retinoid irritation over time.
The tradeoff worth understanding: if you skip retinoid use for a week or two and then restart, the irritation can come back temporarily. This is why consistency matters—using it every single night (or as prescribed) is actually easier on your skin than using it three times a week with breaks. You must also use broad-spectrum SPF 30+ sunscreen daily because retinoids increase sun sensitivity. Serious side effects like severe allergic reactions are rare, occurring in less than 1% of users. Pregnancy is a contraindication, as with all retinoids, due to teratogenic risks.
Who Should Actually Use Trifarotene?
Trifarotene makes the most sense for patients with moderate acne (not mild, not severe) on both the face and body, especially those who failed gentler options first or who have very oily, resilient skin that tolerates retinoids well. The FDA approved it for patients 9 years and older, so it can be used in adolescents, though dermatologists typically prefer to try gentler options (like adapalene or benzoyl peroxide) in younger teenagers first. Adults with persistent body acne—a real problem that’s often overlooked because people focus on face acne—are ideal candidates. However, trifarotene is not right for everyone.
Patients with very sensitive or dry skin often struggle with retinoid irritation regardless of how selective the retinoid is. If you have severe nodular acne, isotretinoin (Accutane) is still the appropriate choice, not trifarotene, because isotretinoin is the only drug that can potentially cure severe acne permanently. Pregnant women, patients with severe eczema, and anyone using other retinoids shouldn’t start trifarotene without stopping the other medication first. If you’re on oral antibiotics, trifarotene can be layered in, but this combination is typically used for moderate acne that’s resistant to single-agent therapy.
Cost, Insurance Coverage, and How to Get It
Aklief is a brand-name medication, and without insurance, the cost is typically $200-300 per month for a 45-gram tube, which usually lasts 4-6 weeks depending on how much you apply. This is substantially more expensive than generic tretinoin (usually $20-40 per month) or adapalene (generic versions around $30-60). Insurance coverage varies widely—some plans cover it as a tier 2 or tier 3 drug, while others require you to fail cheaper alternatives first through prior authorization. You’ll need a prescription from a dermatologist or primary care doctor.
One practical consideration: a 45-gram tube is a modest amount if you’re treating your entire body with acne. A patient treating face, chest, back, and shoulders might go through a tube in 3-4 weeks rather than the typical 6-week timeline for face-only users. If cost is a concern and you only have facial acne, ask your dermatologist about generic tretinoin or adapalene first—they’ll save you thousands per year and have strong evidence for face. If you truly have widespread body acne that affects your quality of life and didn’t respond to cheaper options, the higher cost of trifarotene may be worth it to actually treat the full problem.
The Future of Topical Retinoid Therapy
Trifarotene represents a shift toward more selective, receptor-targeted retinoids rather than the “hit everything” approach of earlier generations. The success of selective RAR gamma activation suggests we may see additional selective retinoids in the pipeline, potentially targeting different skin conditions beyond acne. The field is also moving toward combination products—for example, trifarotene plus benzoyl peroxide or trifarotene plus a mild antibiotic to reduce resistance concerns.
From a broader perspective, trifarotene has also highlighted an overlooked clinical problem: body acne is real, underdiagnosed, and undertreated. Before trifarotene, dermatologists had limited evidence-based options for truncal acne, so many patients went untreated. As awareness grows that body acne can be addressed with the right retinoid, we may see more systematic treatment of this complaint rather than just facial focus.
Conclusion
Trifarotene is a genuine advance in acne treatment because it’s the first topical retinoid with clinical evidence for treating both facial and body acne, making it a practical option for patients with widespread acne that other retinoids haven’t adequately addressed. The October 2019 FDA approval was the culmination of years of research into more selective retinoid molecules, and the clinical data (29-42% improvement rates in phase 3 trials) supports its use, with most side effects front-loaded into the first 4 weeks of treatment. That said, it’s not a miracle drug and not right for everyone.
For mild facial-only acne, cheaper options like adapalene work fine. For severe acne, isotretinoin is still necessary. For moderate acne on the face and body in patients who can afford it and tolerate retinoids, trifarotene is worth asking your dermatologist about—especially if you’ve been frustrated that body acne gets ignored in standard acne treatment regimens.
