What Is Kerasal?
Kerasal is a brand consisting of foot and nail care products available without a prescription. Products from this brand are specifically created to improve damaged nails and dry, cracked feet. It is a cosmetic brand that focuses not on medical treatment but rather on renewal, making them over-the-counter products for restoring the nails and feet’s smooth and healthy appearance.
Some of the benefits that products from this brand claim to offer include reducing discoloration on the nails, softening thickened nails, exfoliating and hydrating dry and cracked heels to improve their texture and appearance over time. Kendal formula claims to be widely used in the United States by individuals looking for non-prescription medication options to restore fresh feet and nails affected by fungus and aging.

How Does Kerasal Work?
Kerasal formula claims to utilize a patented formula that features a combination of efficient ingredients, including urea and propylene glycol, that work through different mechanisms of action to improve nail and skin texture and appearance.
Urea, for instance, helps improve scaly and dry skin, leaving it smooth and hydrated. According to a research study published in Dermatology and Therapy, urea works to achieve this by regulating keratinocyte proliferation and gene expression in keratinocytes, which is relevant for antimicrobial peptide production.[1]
Propylene glycol on the other hand, has been found to improve skin hydration by enhancing small molecule permeation, including water interaction with the bylayer interface. This is according to a publication in the Journal of Physical Chemistry.[2]

Kerasal Ingredients
Kerasal formula claims to combine potent ingredients. Some of the key ingredients include the following:
Propylene Glycol – Propylene glycol is a great moisturizing ingredient known to enhance penetration, which helps in the absorption of ingredients deeper into the skin and nail, thus ensuring improved hydration. It has humectant properties, making it a helpful agent when it comes to maintaining softness and preventing dryness.
A study published in Archives of Dermatological Research notes that propylene glycol has moisturizing effects and can help in ensuring penetration of the product.[3] However, according to the results of the study, some subjects, especially those with sensitive skin, experienced mild allergic reactions and irritation upon frequent topical application, which may question the safety of this ingredient to some users.
Glycerin – Glycerin is popularly known for its hydrating benefits. It aids in drawing moisture and retaining it in the skin, keeping it hydrated.
According to research published in the British Journal of Dermatology, glycerin has been shown to improve skin barrier recovery and hydration.[4]
Urea – Urea is one of the key ingredients in the Kerasal formula, believed to contain exfoliating properties. It can help to soften dry skin and brittle or thick nails, naturally loosening and shredding damaged layers, which improves the nail and skin texture, leaving the surface smoother.
A review in Dermatology and Therapy reports that topical use of urea can help improve scaly, dry skin and restore surface smoothness.[5] However, since the results depend partly on the concentration, it is difficult to tell whether the Kerasal formula contains the right concentration that can guarantee this ingredient’s efficiency.
Sodium Hydroxide – Sodium hydroxide is used in the formulation of Kerasal to help balance the pH in the formula to improve product stability and effectiveness.[6] It works to ensure that ingredient like lactic acid works to benefit the skin while being gentle. A high level of pH in topical products can cause a burning sensation and irritation.

Mild sensitivity, redness, or burning sensations are highly likely to occur in the area applied. However, these reactions mostly occur if you have sensitive or broken skin.

Unimpressive Results, Cosmetic Only Effectiveness
I used Kerasal for months expecting clear, healthy nails — but the improvement was minimal at best. My nails looked only slightly less discolored, and fungal signs remained. It seems more like a cosmetic polish than a real solution.
