Background: Chemical exfoliation of the skin is a frequently utilized treatment in dermatology to improve the appearance and health of photoaged skin. Photodamaged skin is especially prone to dryness and irritation. Over-exfoliation with at-home products are partially to blame for the "epidemic" of sensitive skin affecting over half the population. Combining AHA, BHA, and PHA together creates a complementary blend that has the potential to target numerous age-related changes in the skin including the appearance of pores and smoothing skin texture, while firming skin and increasing its collagen and moisture content.
Objectives: The following study tested the clinical efficacy of a triple acid blend designed specifically for sensitive skin and measured improvements in signs of photodamage and hydration levels in the skin over time.
Methods: Thirty females aged 35-60 with mild to moderate facial lines, wrinkles, sun damage, uneven skin tone/texture, dark spots, or pores were enrolled. Subjects were instructed to use the test article, DWB-EN, on a clean face at night 3 times weekly with 48 h between applications for 4 weeks.
Results: Statistically significant improvements were noted in all parameters of photoaging clinical assessments (wrinkles, pores, overall appearance, luminosity, visible texture, skin tone evenness, hyperpigmentation) at the end of the 4-week study period. There were no instances of skin irritation throughout the duration of this study despite half of the women having sensitive skin.
Conclusions: Overall, this study demonstrated the clinical efficacy and tolerability of DWB-EN for treating photoaging in subjects with all skin types.
