Based on its formula, is Croissance! suitable for sensitive or damaged nails?

The polish includes soothing components such as glycerin, panthenol and vitamins that can help hydrate and strengthen the nail plate, but it also contains fragrance, phenoxyethanol and synthetic dyes that are known irritants; therefore, users with highly sensitive or damaged nails should perform a patch test before regular use.

What benefit does retinyl palmitate provide in a nail growth polish?

Retinyl palmitate is a vitamin A ester that promotes cell turnover and collagen synthesis, helping to reinforce the nail matrix and support faster, healthier nail growth when applied consistently.

What is the recommended application frequency for Croissance! and does it contain any controversial chemicals?

The product is intended for daily or every-other-day use as a base or top coat, and it contains phenoxyethanol, synthetic colourants (CI 77007, CI 42090, Yellow 5, blue) and a UV-filter, all of which are approved for cosmetic use but may be a concern for individuals with fragrance or dye sensitivities.

Product Insights

Croissance! is a 10 ml nail polish from Agnes b that markets itself as an energising treatment for short nails to promote growth. The formula blends moisturizing agents such as glycerin and panthenol with vitamins A (retinyl palmitate), C (magnesium ascorbyl phosphate) and E (tocopheryl acetate) and includes a UV-filter (benzophenone-4) for colour protection, while polymers create a smooth, durable finish. Nevertheless, it contains fragrance, phenoxyethanol, several synthetic colourants (CI 77007, CI 42090, Yellow 5, blue) and lactose, which may irritate sensitive skin and makes the product unsuitable for vegan users.

Comparative Analysis

Positioned as a growth-boosting nail polish, Croissance! stands out by combining vitamin-rich active ingredients and a UV-filter in a compact 10 ml bottle, targeting consumers who want both colour and nail-strengthening benefits.
