2 Week Spot Study

Study Summary

Alba Science would like to invite you to participate in a 2 week spot study.  Skin inflammatory lesions or blemishes are disorders of the sebaceous gland.  Excessive sebum which is responsible for skin imperfections contribute to proliferation of bacteria Propionibacterium acnes (P. Acnes). This microorganism (P. Acnes) plays a role in the inflammatory phase of skin lesions/blemishes.

You are being asked to participate in a research study to evaluate a plasma home device.  The device will either be used on its own on incipient skin inflammatory lesions (spots), or in combination with a product and will be compared against the same cosmetic formula.  It is hoped that by combining the 2 treatments, the effects of these treatments on skin imperfections will be faster.

The duration of the study will be a maximum of 15 days for each person, including a wash-out period of at least 2 days.  The wash out period will be followed by a maximum of 10 days of treatment period but could be less.

Approximately 50-100 male/female volunteers, with oily or combination oily skin, with at least 2-4 skin inflammatory lesions on each side of the face, in the beginning phase (emerging spots) will be recruited.

You should not be taking any regular medication which may influence the response of the skin, e.g. anti-inflammatory medication, steroids or anti-histamines.
