Simplify body care by using targeted active ingredients: glycolic acid for bumpy arms, urea for rough heels, lactic and kojic acids for underarm radiance, ceramides for dry skin, and a peptide-retinol duo for skin firmness.

Science largely supports these targeted body care recommendations. For dry skin, a 2020 systematic review in the Journal of Cosmetic Dermatology confirms that ceramides effectively restore the skin's moisture barrier. The efficacy of urea on rough feet is also validated by clinical trials (RCTs), notably a 2021 study in Dermatology and Therapy demonstrating its excellent exfoliating and softening properties. For bumpy arms and shadowy underarm areas, the use of glycolic, lactic, and kojic acids is based on solid observational and formulation data regarding exfoliation and evening out skin tone, although the sensitive underarm area requires gentle concentrations to avoid irritation. Finally, the action of retinol on skin firmness is validated by numerous randomized controlled trials (RCTs) showing an improvement in elasticity, while peptides provide complementary moisturizing support, although their direct firming effects are more subtle.
