What creators are saying
TikTokTikTok reviewers are enthusiastic about this serum, highlighting its lightweight, fast-absorbing formula and visible results like smoother skin texture, reduced pores, and faded acne scars within days to weeks. They love that it's vegan, gentle enough for sensitive skin despite containing retinol, and affordable at $37, with one reviewer noting it absorbs significantly better than salmon-derived alternatives. They recommend it for anyone ready to get serious about skincare, particularly those with maturing skin, enlarged pores, or uneven texture who want an effective but non-irritating retinol option.
