The Formula
Active Ingredients & The Science Behind Them
Every ingredient in BYM Skin Care KP Treatment Cream was chosen for a specific, clinically validated reason. Together, they address KP from four distinct angles exfoliation, hydration, barrier repair, and regeneration.
Lactic Acid 5%
Niacinamide
Saffron Stem Cell Extract
UREA 20%
The Deep Hydrator
UREA 20%
Urea is a naturally occurring molecule in healthy skin’s Natural Moisturizing Factor (NMF). At 20% concentration, it acts as a powerful keratolytic breaking down the excess keratin buildup that forms KP bumps while simultaneously drawing water deep into the stratum corneum.
How It Works
Disrupts hydrogen bonds in keratin protein structures, softening and dissolving the plugs that block hair follicles. Simultaneously increases skin’s water-binding capacity by up to 400%.
Visible Outcomes
- Visibly reduces bump height within 2–4 weeks
- Deeply hydrates dry, rough skin texture
- Softens and loosens keratin plugs
- Restores skin’s natural moisture barrier
The BYM Skin Care Synergy Difference
Most KP products address only one problem. BYM Skin Care combines all four actives in precisely calibrated concentrations so they amplify each other’s effects exfoliating, hydrating, calming, and regenerating simultaneously.

At concentrations above 10%, urea transitions from a pure humectant into a keratolytic agent — actively breaking down the abnormal keratin plugs that define KP. A 20% concentration hits the therapeutic sweet spot: potent enough to exfoliate hyperkeratotic follicles, yet well tolerated for daily use.

KP is fundamentally a keratin-overproduction problem. The most effective topical strategy combines a keratolytic urea at 20% is ideal with an AHA like lactic acid to dissolve the plug from two angles simultaneously. Urea also restores the moisture barrier that KP chronically disrupts.
