The 20% glycolic acid concentration at a pH of 3.0 means the acid is active and potent enough to break down the bonds between dead, thickened skin cells, a process called corneodesmolysis. This level of exfoliation goes beyond what lighter AHA concentrations or standard moisturizers can achieve on heavily calloused areas. The addition of sorbitol, glycerin, and conditioning oils means skin is simultaneously softened and hydrated as the rough texture is reduced.

Yes, this cream is formulated to address keratin expression changes and hyper-proliferation disorders, which are characteristic of psoriasis-related skin thickening on the body. The recommended protocol for severely calloused or psoriasis-affected skin is to apply twice weekly to the affected area. Consistency with the protocol is key to seeing results.

This cream is formulated for use on body skin, specifically rough areas like heels, elbows, and knees. A 20% glycolic acid concentration at pH 3.0 is a high-strength formulation designed for thickened body skin, which is significantly more resilient than facial skin. It is not intended for use on the face.

For callous reduction on feet, a one-week nightly application followed by a pumice stone session typically produces noticeable softening. Ongoing use every other night helps maintain results and prevents buildup from returning. Skin that is severely thickened may take longer to respond, and consistency with the application schedule makes a significant difference.

The formula includes calendula, chamomile, cucumber, green tea, and hops extracts, which collectively provide antioxidant protection and help calm skin during the exfoliation process. Lavender extract contributes to the mild scent while also offering soothing properties. These botanicals help balance the intensity of the high-strength glycolic acid, making the experience more comfortable for skin.

Because of the high glycolic acid concentration, those with sensitivity to alpha hydroxy acids should use this cream only as needed rather than on a regular schedule. If redness, stinging, or irritation develops, discontinue use. Starting with less frequent application allows skin to adjust before building up to more consistent use.

This cream is free of added synthetic fragrance and parabens. The mild scent comes from lavandula angustifolia (lavender) flower and leaf extract, which is a botanical ingredient, not a synthetic fragrance additive. The formula is preserved with phenoxyethanol and ethylhexylglycerin rather than parabens.
