Aklief Side Effects: What to Expect and When to Call Your Doctor

If your dermatologist prescribed Aklief (Trifarotene) for your acne, you're probably wondering what side effects to expect. The short answer: some skin irritation is completely normal in the first few weeks, and it usually gets better as your skin adjusts. But there are a few side effects that deserve a call to your doctor.

This guide covers everything you need to know about Aklief's side effects — from the common and manageable to the rare and serious — so you can start treatment with confidence.

What Is Aklief? (Quick Overview)

Aklief is a topical retinoid cream containing Trifarotene 0.005%. It's FDA-approved for treating acne vulgaris in patients 9 years and older. Unlike older retinoids, Aklief selectively targets retinoic acid receptor gamma (RAR-γ), the most common retinoid receptor in skin. This targeted approach was designed to improve acne while potentially reducing some of the irritation associated with older retinoids.

Aklief is manufactured by Galderma and comes as a 45g airless pump. It's applied once daily in the evening. For a deeper look at how it works, read our guide on how Aklief works.

Common Side Effects

Most people who use Aklief will experience some degree of skin irritation, especially during the first 2 to 4 weeks of treatment. These side effects are expected and usually temporary:

• Application site irritation: General discomfort, sensitivity, or tenderness at the area where you apply the cream
• Skin dryness: Flaking, tightness, or a rough texture — one of the most common complaints
• Skin redness (erythema): Pink or red patches at application sites, particularly on the face
• Skin scaling or peeling: Your skin may visibly flake or peel as it adjusts to the retinoid
• Itching (pruritus): Mild to moderate itching at the application site
• Stinging or burning sensation: A brief sting or burn immediately after applying the cream, usually lasting a few minutes
• Sunburn: Increased sensitivity to UV light can lead to sunburn more easily than usual

These effects are signs that the retinoid is working — Aklief increases skin cell turnover, which causes old, dead skin cells to shed faster. Think of it as your skin's adjustment period.

How Long Do Common Side Effects Last?

For most patients, the irritation peaks during weeks 1 through 4 and gradually improves. By week 6 to 8, most people find that dryness, redness, and peeling have significantly decreased. If you can push through the first month, it typically gets much easier.

Serious Side Effects

Serious side effects from Aklief are uncommon, but they can happen. Contact your doctor if you experience:

• Severe skin irritation: Intense redness, swelling, blistering, or crusting that doesn't improve after reducing application frequency. If your skin is so irritated that it's painful or interfering with your daily life, your doctor may recommend pausing or discontinuing Aklief.
• Severe allergic reaction: Symptoms like hives, swelling of the face or throat, difficulty breathing, or severe rash. This is rare but requires immediate medical attention.
• Severe sunburn or photosensitivity reaction: Even with sunscreen use, some patients may develop significant sunburn or a photosensitivity reaction with blistering. If you notice an exaggerated sunburn response, stop sun exposure and contact your doctor.

Aklief does not carry a boxed warning (the most serious type of FDA warning). This is an important distinction from some other acne medications like isotretinoin (Accutane), which has extensive warnings.

Side Effects in Specific Populations

Adolescents (Ages 9 to 17)

Aklief is approved for patients 9 years and older. Side effects in adolescents are similar to adults — skin irritation, dryness, and redness are the most common. Parents should help younger patients with application technique and sun protection.

Pregnancy and Breastfeeding

Aklief should be used with caution during pregnancy. While topical application results in minimal systemic absorption, animal studies showed adverse fetal effects at high exposures. There is no adequate human data. If you are pregnant, planning to become pregnant, or breastfeeding, talk to your doctor before using Aklief. It is not established whether Trifarotene passes into breast milk.

Older Adults

There are no specific studies of Aklief in geriatric populations. If you're an older adult using Aklief, follow the same precautions — moisturize, use sunscreen, and start slowly.

How to Manage Aklief Side Effects

The good news is that most Aklief side effects are manageable with the right approach. Here's what dermatologists typically recommend:

Start with Moisturizer

Apply a gentle, fragrance-free moisturizer from day one. Don't wait until your skin gets dry — proactive moisturizing can significantly reduce irritation. Good options include CeraVe Moisturizing Cream, Vanicream, or La Roche-Posay Toleriane.

Apply to Dry Skin

Wait at least 15 to 20 minutes after washing your face before applying Aklief. Applying to damp skin can increase irritation because the medication absorbs more readily.

Use a Pea-Sized Amount

More is not better. A thin, even layer across the affected area is all you need. Using too much won't clear acne faster — it'll just increase irritation.

Build Up Gradually (If Needed)

If your skin is sensitive, consider starting with every other night for the first 1 to 2 weeks, then increasing to nightly use as your skin tolerates it. Some dermatologists call this "retinoid ramping."

Wear Sunscreen Every Day

Aklief increases your skin's sensitivity to UV light. Wear SPF 30 or higher every morning, even on cloudy days. Reapply if you're spending time outdoors. A broad-spectrum mineral sunscreen (zinc oxide or titanium dioxide) is often best for sensitive skin.

Avoid Harsh Products

While using Aklief, minimize use of other potentially irritating skincare products:

• Avoid other topical retinoids (Tretinoin, Adapalene, Tazarotene) — don't double up
• Use caution with benzoyl peroxide, salicylic acid, or glycolic acid — these can increase dryness and irritation when combined with Aklief
• Avoid alcohol-based toners, astringents, or exfoliating scrubs

Protect Sensitive Areas

Avoid applying Aklief to cuts, scrapes, eczema patches, or sunburned skin. These areas are already compromised and will become significantly more irritated. Also avoid waxing any skin areas where you apply Aklief.

When to Call Your Doctor

Contact your dermatologist or prescribing provider if:

• Irritation is severe or getting worse after 4 weeks (it should be improving by then)
• You develop blistering, crusting, or open sores at application sites
• You have signs of an allergic reaction (hives, facial swelling, difficulty breathing)
• You experience a severe sunburn even with sun protection
• You become pregnant or are planning to become pregnant while using Aklief
• Your acne is significantly worse after 12 weeks of consistent use (some initial worsening is normal, but you should see improvement by 8 to 12 weeks)

Don't stop Aklief without talking to your doctor first. Mild irritation in the early weeks is expected and doesn't mean the medication isn't working.

Final Thoughts

Some skin irritation with Aklief is normal — and it's actually a sign the retinoid is doing its job. Dryness, redness, peeling, and mild stinging are common in the first few weeks and usually improve by week 6 to 8. The key is to moisturize generously, use sunscreen daily, and give your skin time to adjust.

If side effects become severe or don't improve, your doctor can help adjust your routine — whether that means using Aklief less frequently, adding a barrier cream, or trying a different treatment.
