What kinds of moisturizers are generally safe with Cosentyx (secukinumab)?
Cosentyx (secukinumab) targets the immune system and is used for conditions like plaque psoriasis. For most people using Cosentyx, the “safest” moisturizer is one that is simple, fragrance-free, and made for sensitive skin—because irritated or barrier-damaged skin can itch, flare, or feel uncomfortable regardless of the biologic. Look for:
- Fragrance-free and dye-free formulas
- A gentle emollient base (creams, ointments, or thick lotions that reduce dryness)
- Ingredients aimed at hydration and skin-barrier support (common examples in many products include glycerin, ceramides, petrolatum, or dimethicone)
Which moisturizer ingredients should Cosentyx users avoid or be cautious with?
Cosentyx itself doesn’t dictate a single “forbidden” ingredient list in the way it would for specific drug-drug interactions. Instead, the biggest practical issue is irritation. Many patients avoid moisturizers that are more likely to sting or trigger contact dermatitis, such as:
- Fragrances and essential oils
- Strong acids or exfoliating blends (for example, leave-on products with high concentrations of glycolic/lactic acid)
- Menthol, camphor, or “cooling” agents if they irritate your skin
- Products that you already know cause redness, burning, or itching
If a moisturizer burns or makes plaques itch more, stop it and switch to a plain, fragrance-free option.
Are steroid-free moisturizers enough if I’m still flaring?
Many people can manage dryness and scaling with barrier moisturizers alone. If you have active inflamed plaques, dryness-related itching may not fully improve with moisturizing alone. In those cases, clinicians often use targeted psoriasis treatments (which can include topical corticosteroids or other therapies) alongside regular moisturization. Moisturizer stays important, but it may not replace anti-inflammatory treatment when plaques are actively inflamed.
Can I use “medicated” moisturizers (anti-itch, anti-eczema, etc.)?
Medicated moisturizers can be okay if they are gentle and you tolerate them, but they’re more likely to irritate than basic emollients—especially if they contain fragrances, multiple active botanicals, or strong anti-itch ingredients. A cautious approach is:
- Start with a plain fragrance-free moisturizer first
- Add medicated products only if your clinician says they fit your regimen and your skin tolerates them
Patch test and step-in approach if you’re trying a new brand
A safe way to find a moisturizer that works for you while on Cosentyx is to:
- Apply a small amount to a limited area for a few days
- Stop and switch if you get burning, increased redness, or new bumps
- Once tolerated, use it consistently, especially after bathing and before bed
What to do if your skin reaction happens after starting a moisturizer
If you notice worsening redness, hives, swelling, or significant burning after applying a moisturizer, treat it as a possible sensitivity and discontinue that product. If you have widespread blistering, severe swelling, or breathing trouble, seek urgent care. For milder irritation, contact your dermatologist or prescribing clinician.

The information above is general skin-care guidance based on tolerability and irritation risk for moisturizers. I don’t have product-specific data in the material provided, and I can’t reliably name specific “approved” moisturizer brands for Cosentyx users without additional details (country, product ingredients, and your skin condition).
If you share:
1) which country you’re in,
2) whether you have plaque psoriasis, eczema, or just dryness, and
3) the moisturizer name(s) you’re considering (or ingredient lists),
I can help you screen them for common irritants and suggest safer alternatives.
