Adalene: What In It and How It Works

Adalene is Nolla’s restorative nighttime formula built around adapalene - a synthetic retinoid - combined with niacinamide to support the skin through the adjustment process. If this is your prescription, your clinician has determined that a retinoid-based approach is right for your skin, and that adapalene is the appropriate starting point given your skin’s tolerance profile.

What’s In Adalene

Adapalene is a third-generation synthetic retinoid. Like tretinoin, it works by binding to retinoid receptors in skin cells and accelerating cell turnover - the process of pushing new cells to the surface while clearing dead cells from the follicle, which prevents the blockages that cause acne. It also reduces inflammation in and around the follicle.

The key distinction between adapalene and tretinoin is tolerability. Adapalene binds more selectively to specific retinoid receptors, which means it delivers retinoid-level efficacy with significantly less irritation, dryness, and peeling during the adjustment period. For patients who are new to retinoids, or whose skin has previously found tretinoin too aggressive, adapalene provides the same mechanism through a more manageable path.

Niacinamide reinforces the skin barrier, reduces inflammation, and inhibits melanin transfer to address the post-acne marks that sit alongside active breakouts.

What To Expect - And When

Weeks 1–3: Some purging and adjustment is expected. Adapalene accelerates cell turnover, so congestion beneath the surface gets pushed up faster. The purging response is typically milder with adapalene than with tretinoin.

Weeks 4–6: Purging settles. New breakouts should be less frequent, and initial dryness or irritation typically resolves.

Weeks 8–12: Fewer comedones, reduced inflammatory breakouts, and early improvements in skin texture and post-acne marks. Adapalene’s benefits compound over time - effects on texture and collagen continue to develop well beyond 12 weeks.

How To Use It

Adalene is a nighttime formula - apply it in the evening after cleansing and before moisturizer. Retinoids are photosensitive and work more effectively overnight.

• SPF every morning. Adapalene increases UV sensitivity. Daily SPF both protects photosensitized skin and prevents UV from deepening post-acne marks.
• Moisturize after application. A non-comedogenic moisturizer reduces irritation and supports overnight barrier repair.
• You can start with every-other-night application if your skin is very new to retinoids. Build to nightly use over the first two weeks.
• No additional actives in the same evening routine. Avoid AHAs, BHAs, vitamin C, and additional retinoids alongside Adalene.
• Avoid during pregnancy. Retinoids are contraindicated in pregnancy - flag any change in circumstances through the app immediately.

Who Adalene Is Designed For

Adalene is best suited to patients who need a retinoid-based approach but whose skin is sensitive, reactive, or new to prescription actives. It delivers the same core mechanism as tretinoin with a more manageable adjustment period. It’s also a logical starting point for anyone whose previous experience with retinoids involved significant irritation.

The Bottom Line

• Adapalene is a synthetic retinoid that accelerates cell turnover and clears follicle blockages - the same mechanism as tretinoin, with a gentler tolerability profile
• Niacinamide manages inflammation, barrier disruption, and post-acne pigmentation during the adjustment period
• Mild purging in weeks 1–3 is expected; it’s milder than with tretinoin and settles within the first month
• Daily SPF is essential - retinoids increase UV sensitivity significantly
• Adalene is the right retinoid choice for skin that needs a retinoid but hasn’t tolerated stronger options well
