A widely used humectant, skin conditioner, and solvent (CosIng) that supports hydration and may help improve barrier function. Found in 11,581 products in our database, Panthenol is commonly formulated for sensitive, dry, and compromised skin.
This moisturizing compound acts as a humectant to attract and retain water in the skin, and may help improve stratum corneum hydration and barrier function. It's commonly added to skincare formulations for its conditioning properties and ability to improve skin texture and softness. This ingredient has a favorable safety profile and is generally well-tolerated, though rare contact dermatitis cases have been documented in the CIR assessment. Individual tolerance may vary.
Panthenol (INCI: Panthenol, CAS 81-13-0) is the alcohol analog of pantothenic acid (Vitamin B5). Once absorbed into the skin, Panthenol is enzymatically converted to pantothenic acid, which is a key component of Coenzyme A — essential for numerous metabolic processes including fatty acid synthesis and energy production in skin cells. This conversion is what makes Panthenol a "provitamin." It exists as D-Panthenol (the biologically active form) and DL-Panthenol (a racemic mixture), both widely used in cosmetics.
The CIR Expert Panel assessed Panthenol, Pantothenic Acid, and five derivatives in 2022 and concluded they are safe as used in cosmetics at present practices and concentrations. According to FDA VCRP data, Panthenol is reported at maximum concentrations of 5.3% in leave-on products and 5% in rinse-off products (these are observed industry values, not recommended or regulatory limits). The CIR found low potential for systemic toxicity, but noted that these ingredients may contain residual amines as impurities and should not be used in products where N-nitroso compounds may form.
Panthenol is a humectant that can penetrate the stratum corneum and help retain water, supporting moisture levels in the skin. It may contribute to both immediate and sustained hydration, helping to reduce dryness and flakiness over time.
Some studies suggest panthenol may support epidermal recovery, with supportive evidence for effects on cell proliferation and barrier restoration. This is why it is commonly found in repair-oriented ointments and post-procedure products. However, evidence strength varies by study design and formulation context.
Panthenol is commonly associated with soothing properties for irritated and sensitive skin. Some literature suggests it may help reduce irritation from environmental stressors and harsh skincare actives. It is frequently included in post-exfoliation and recovery formulations.
Panthenol may help improve stratum corneum hydration and support barrier function. Some studies have observed improvements in TEWL and barrier recovery, though results can vary depending on formulation, concentration, and study design.
Generally suitable for: Most skin types — especially sensitive, dry, irritated, and post-procedure skin. Also used in hair conditioning. Individual tolerance may vary.
The CIR Expert Panel (2022) concluded that Panthenol and its derivatives are safe as used in cosmetics at present practices and concentrations. EU approved with no restrictions. A generally well-tolerated provitamin with a favorable safety profile.
The CIR Panel noted that Panthenol may contain residual amines as impurities and therefore should not be used in cosmetic products in which N-nitroso compounds may be formed. This is a formulation-level consideration addressed during product development.
Published literature and market formulations commonly use panthenol in the low-to-mid single-digit percent range. CIR 2022 reports maximum observed concentrations of 5.3% (leave-on) and 5% (rinse-off) — these are industry-reported values, not clinically established optimal concentrations.
Both D-Panthenol and DL-Panthenol are used in cosmetics. D-Panthenol is the biologically active form and is generally preferred for skin benefits, while DL-Panthenol works well for hair conditioning.
Panthenol (Pro-Vitamin B5) is a water-soluble vitamin precursor naturally found in many foods including eggs, meat, and whole grains. The CIR 2022 assessment found low systemic toxicity potential. Topical panthenol is generally considered a low-risk ingredient during pregnancy based on its overall low toxicity, limited systemic exposure from topical application, and long history of cosmetic use — though this assessment is not based on dedicated pregnancy clinical trials. It is commonly found in sensitive-skin and some baby care formulations. Always consult your healthcare provider for personal advice.
Two humectants often used together. Both support skin hydration, though their performance depends on concentration, formulation, and product design rather than a simple deep/surface distinction. Complementary humectants in many skincare routines.
Panthenol (B5) and Niacinamide (B3) are a classic B-vitamin duo. Niacinamide strengthens the barrier and controls oil, while Panthenol hydrates and calms. They complement each other perfectly.
Panthenol may support barrier function while ceramides contribute to the intercellular lipid matrix. Together they are commonly combined in barrier-recovery formulations for dry, damaged skin.
Panthenol's soothing and hydrating properties help offset retinol's dryness and irritation. Apply retinol first, then layer Panthenol to calm and protect the skin during retinoid therapy.
Very high-concentration acid peels can temporarily compromise the skin barrier. Use Panthenol as a post-peel recovery treatment rather than layering it simultaneously with the peel.
Per the CIR caution, Panthenol should not be combined in formulations where N-nitroso compounds could form. This is a formulation-level consideration addressed during product development.
