Effects of VitaminC Peeling on Skin Condition Improvement

This study compared the effects of vitaminCC 40% peeling and AHA peeling on skin condition and examined short-term changes and maintenance patterns through repeated measurements. Adult women were randomly assigned to an experimental group receiving vitaminC 40% peeling and a control group receiving AHA peeling. Facial skin conditions were objectively assessed at five time points: before treatment, immediately after the first peeling, one week after the first peeling, immediately after the second peeling, and one week after the second peeling. The evaluation parameters included skin moisture, sebum, elasticity, roughness, and pigmentation. In the vitaminC 40% peeling group, sebum levels decreased after each peeling session and remained lower at the one-week follow-up after the second peeling, indicating relatively consistent sebum control over time. Pigmentation values also showed a noticeable reduction immediately after peeling, and this improvement was maintained through the final measurement point. Elasticity temporarily increased after peeling and gradually returned toward baseline, suggesting transient stimulation followed by recovery. In contrast, the AHA peeling group exhibited temporary increases in moisture and elasticity immediately after peeling; however, these effects diminished across subsequent measurements, with values tending to return toward baseline levels. Sebum and roughness showed less consistent patterns, with partial rebound observed during the follow-up period. In conclusion, vitaminC 40% peeling demonstrated relatively sustained effects compared to AHA peeling, suggesting its potential applicability in aesthetic skin care practice.
