Effect of Helix aspersa Mucus on the Regeneration of Skin with Photoaging Features in Different Methods of Application

Skin aging is associated with both intrinsic and extrinsic aging, with extrinsic aging caused by environmental factors and overlaying the effects of chronological aging. The main aim of this study was to evaluate the effect of preparations containing Helix aspersa snail mucus on skin regeneration with photoaging features. Before and 3 months after the series of treatments, skin biopsy specimens from the right preauricular region of the face were taken from six women. Histological, morphometric, and immunohistochemical analyses were performed. Positive changes, indicating a reduction in photoaging related to the reduction in epidermis thickness 3 months after the end of the treatments, were noted in each group. A statistically significant increase in the thickness of the collagen fiber bundles was also observed in the patients 3 months after a series of micro-needle mesotherapy treatments with snail mucus and 0.9% NaCl. There was a significant increase in the immuno-expression of Ki-67 and PCNA in the dermis. The aforementioned significance applies to patients in whom snail mucus was introduced with the use of micro-needle mesotherapy and needle-free mesotherapy. Moreover, a statistically significant increased area with the immunoexpression of MMP-2 in the dermis was observed in the above-mentioned groups of patients, who were treated with the preparation containing snail filtrate. The results of the study suggest that the use of snail mucus preparations for skincare, as well as its introduction by micro-needle and needleless mesotherapy, had a beneficial effect on the condition of the skin.
