trans epidermal water loss(TEWL), stratum corneum hydration and visual analog scale were measured at 2-week intervals for 6 weeks.

Treatment
Other |
The volunteer with mild-to-moderate atopic dermatitis were given an 4-week treatment with oral collagen tripeptide (4g/day).
The volunteer with mild-to-moderate atopic dermatitis were given an 4-week treatment with oral lactose (2g/day) as placebo control.
The volunteer with mild-to-moderate atopic dermatitis were given an 4-week treatment with topical application containing collagen tripeptide on both sides of upper arms(15ml/each arms)more than 2 times per day.
The volunteer with mild-to-moderate atopic dermatitis were given an 4-week treatment with topical placebo-applicatio(without collagen tripeptide) on both sides of upper arms(15ml/each arms)more than 2 times per day.

Seventeen AD patients were assigned randomly. Four patients dropped out of. The eruption area and SCORAD score were significantly decreased in theCTP group. TEWL levels were improved in the CTP group. Skin hydration tended to elevate, but did not reach statistical significant.In blood samples, a significantly reduction in the TARC level was seen only CTP group. The levels of serum LDH and IgE were not changed in either group. In the control group, eosinophil counts were increased compared to baseline.
2019 | Year | 09 | Month | 14 | Day |
Atopic dermatitis patients with mild to moderate disease.
Patients were allowed to use their daily topical products, except on one upper arm.
Eligible patients were assigned randomly under double-blind conditions to receive either a CTP product or normal collagen which does not contain CTP.
Peptides were administered orally for 12 weeks.
