AHAs, particularly glycolic acid and lactic acid, are evidence-backed first-line keratolytic treatments for KP. They reduce corneocyte cohesion, facilitate desquamation of keratin plugs, and improve stratum corneum hydration. A 2025 PMC literature review confirmed AHAs demonstrate potential benefit for KP symptom reduction, and clinical studies show improvements in papule counts and skin texture within 4–12 weeks.

Azelaic acid is recognized as an additional topical treatment for KP, particularly for its anti-inflammatory, antioxidant, and mild keratolytic properties. One clinical study reported 92% of KP participants showed significant improvement in hyperkeratosis erythema after three months. Medscape and a 2020 systematic review list azelaic acid among effective topical treatments for KP appearance.

Ceramides are key lipid components of the skin barrier, and their use in KP management targets the impaired epidermal barrier and xerosis underlying the condition. KP is frequently associated with filaggrin-related barrier dysfunction and atopic dermatitis. Ceramide-containing moisturizers are recommended alongside keratolytics to support barrier repair, and are included in leading dermatologist-recommended KP formulations.

Glycerin is a humectant emollient central to KP moisturizing formulations, addressing the xerosis and skin barrier dysfunction underlying the condition. Emollients are listed as a first-tier treatment by StatPearls, and glycerin is explicitly cited as a key ingredient in dermatologist-recommended KP emollient products. Adequate skin hydration is a cornerstone of all KP management protocols.

A 2024 split-body randomized clinical trial published in the Journal of Cosmetic Dermatology found that injected non-cross-linked hyaluronic acid compound significantly improved skin roughness and promoted hair shaft growth in KP patients, with improvements maintained up to 24 weeks. This represents the first clinical trial demonstrating HA's utility specifically in KP.

Lactic acid is one of the most clinically studied topical keratolytics for KP. In a 12-week randomized controlled trial, 10% lactic acid produced a 66% mean reduction in follicular papules, outperforming 5% salicylic acid. It acts as both a humectant and keratolytic, improving texture and hydration of KP-affected skin, and is among the most dermatologist-recommended first-line ingredients.

Omega-3 essential fatty acid deficiency is associated with dry, rough skin and impaired skin barrier, conditions that underlie and exacerbate KP. Integrative dermatology sources recommend omega-3 supplementation for KP patients when deficiency is detected, as fish oil supplementation influences epidermal fatty acid composition and supports skin barrier integrity.

Topical retinoids (vitamin A derivatives such as tretinoin and tazarotene) are a recognized treatment escalation for KP per StatPearls and Medscape, used when first-line keratolytics are insufficient. Case reports document KP resolution with 0.01% tazarotene applied nightly over 4–8 weeks. Vitamin A deficiency is also associated with dry, rough skin and elevated KP risk.

Niacinamide (vitamin B3) is used as a supportive ingredient in KP management for its anti-inflammatory and skin barrier-repair properties, addressing the perifollicular erythema and barrier dysfunction component of KP. It is consistently included in dermatologist-recommended KP formulations alongside keratolytics and ceramides. Multiple current KP treatment reviews cite niacinamide as a validated barrier-repair adjunct.

Vitamin D3 derivatives are listed in StatPearls as a recognized treatment escalation option for KP beyond first-line keratolytics, for patients who do not respond to initial therapy. This is mechanistically supported by vitamin D3's role in regulating keratinocyte differentiation relevant to KP's follicular hyperkeratosis pathology.

Aloe vera is used traditionally in KP management for its soothing, moisturizing, and anti-inflammatory properties on the rough, irritated follicular skin characteristic of KP. It is recommended in natural KP care protocols as a topical application. Evidence is based on traditional use and aloe vera's established emollient and anti-inflammatory properties in dermatology broadly.

Coconut oil is traditionally used as a topical emollient for KP, with anti-inflammatory and antimicrobial properties that help soothe and moisturize affected skin. It is consistently recommended in natural KP management protocols. A published study found virgin coconut oil supported skin hydration and barrier function more effectively than mineral oil in children with skin discomfort.

Vitamin C deficiency has been associated with rough, keratotic follicular papule presentation characteristic of KP, and adequate vitamin C is important for keratinocyte differentiation and skin barrier maintenance. Integrative dermatology sources recommend supplementation when deficiency is identified in KP patients. Topically, vitamin C is also cited as useful for post-inflammatory hyperpigmentation associated with KP.
