Since its launch, Winlevi® (clascoterone 1%) has attracted widespread attention as the first FDA-approved topical anti-androgen for acne. But beyond the buzz, where does it really fit in the treatment landscape? And what new data is emerging about how it works in combination with other acne medications?
A Quick Recap: What Is Winlevi?
Winlevi works by blocking androgen receptors in the skin. Androgens (like testosterone) are hormones that can drive excess oil production, contributing to acne—especially in hormonally sensitive individuals. Unlike hormonal therapies such as oral contraceptives or spironolactone, Winlevi is topical, making it a unique option for patients who want hormone-targeted treatment without systemic effects.
Is Winlevi Compatible with Other Acne Treatments?
One of the biggest questions surrounding Winlevi has been how to combine it with other standard acne medications—especially benzoyl peroxide (BPO) and retinoids.
A recent in vitro study addressed this. Researchers layered Winlevi with various commonly used acne agents—including benzoyl peroxide, adapalene, tretinoin, and tazarotene—in a simulated skin model. They measured the clascoterone content and stability after co-application.
The key takeaway:
Winlevi remained stable when used alongside benzoyl peroxide.
This is a significant finding because BPO is known to degrade some topical retinoids (like tretinoin) when layered. Since Winlevi is intended for twice-daily use, and benzoyl peroxide is also a staple in many regimens, compatibility makes co-application easier for patients—without requiring complex scheduling or multiple product layers at different times of day.
Extended Shelf Life: Stability Data
Originally, Winlevi came with a one-month shelf life after opening. That raised concerns for some dermatologists and patients, especially those using it more sparingly or combining it with other treatments.
Now, updated six-month stability data confirms that the product remains effective well beyond the initial 30 days—giving patients more flexibility and confidence in its long-term use.
Where Does Winlevi Fit in Acne Treatment?
Winlevi has become a go-to choice for hormonal acne, particularly in patients who:
- Don’t want to take oral hormonal treatments
- Cannot tolerate spironolactone
- Want a non-systemic, well-tolerated option
That said, Winlevi isn’t a replacement for everything. It’s often paired with other topicals—like retinoids, BPO, or triple-combination products like Cabtreo™—to create a more complete regimen.
Looking Ahead
While no major new drugs have entered the acne market in the last few months, layering studies like this one help refine how existing treatments can be combined for better outcomes. And as providers and patients alike continue to look for options that are both effective and well-tolerated, Winlevi’s unique mechanism and growing data set give it a clear place in the future of acne care.
