530 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS (b) (o) Figure 11. Transparent overlay from Fig. 10 showing uplifting layers present (a) initially (12 per cent area black), (b) after 1 h (0.3 per cent area black), and (c) after 5 h (1 per cent area black) zation" probably does not properly describe the mechanism of action of the typical moisturizer prodnets presently being sold. ACKNOWLEDGMENTS The authors are grateful to the microscopists who actually took the SEM pictures (Carol Kazimir, Patricia Kaiser, John Ware) to Richard W. Swayne

SCANNING ELECTRON MICROSCOPY 531 for help in the development of the replicating procedures, and to Dean Law- thers for his suggestions involving the quantitative image analysis. We are also grateful for the stimulating discussions on skin texture and quality with many individuals active in the cosmetics industry including Sal DiBianea (American Can Company) Dr. John Hil]er (Yardley) R. R. Riso (Stepan Chemical) Dr. George Cohen (Bristol-Meyers) Dr. Martin Rieger (Warner- Lambe•) Albert Kligman, M.D. (University of Pennsylvania) Dr. Myra Barker (Pantene) and D. G. Muccia (Leeming/Pacquins). REFERENCES (1) (2) (3) (4) (5) (7) ('8) (9) (lO) (11) (12) R. D. B. Fraser, and G. E. Rogers, Aust. J. Biol. Sci., 8, 129 (1955). R. B. Barnes, C. J. Burton, and R. G.
