Because the Apollinea study had no placebo and all components strongly contributed to anti-aging efficacy, it is impossible to conclude about the impact of snail mucus itself on the biological effect of the cream.

“However, there was no placebo in this study. There was a limited number of participants (12 participants aged 35 and 67). The authors themselves indicated that all the components strongly contributed to the anti-aging efficacy of the final product.
