How we count reviews: https://openreviews.io/en/methodology ## AI summary This concentrated vitamin-based serum is particularly appreciated for its lightweight, non-sticky texture that absorbs easily. Designed to brighten the complexion and fade hyperpigmentation spots, it easily fits into a daily skincare routine, especially as a base under sunscreen. Its gentle formula provides notable comfort, leaving the skin supple and visibly more radiant. Although highly effective for evening out skin tone, fading the deepest and oldest dark spots requires regular and prolonged use over several months to deliver fully visible results. ## Strengths - Material / Texture (21%) - Feel / Usage (17%) - Size (8%) - Comfort (8%) - Price (7%) ## Weaknesses - **Gradual results** — Fading acne scars and stubborn hyperpigmentation requires patience and consistent application. ## Frequently asked questions - Is this serum suitable for sensitive skin? - Does the texture leave a sticky effect after application? - How long does it take to see effects on dark spots? - Can it be used daily under sunscreen? ## Top reviews ### 4.0/5 · S. D. · October 1, 2025 J’aime beaucoup ce sérum. Très agréable sur la peau. Je ne l’utilise pas tout le temps donc je n’ai pas encore assez d’utilisations pour parler de son efficacité mais il convient très bien pour les peaux mixtes et grasses. Je recommande. ### 5.0/5 · Solange · September 14, 2025 Au bout de 3 mois à l’utiliser tous les matins et en pensant à mettre ma crème solaire après, j’ai vu un éclaircissement significatif de mes tâches profondes que j’ai depuis plusieurs années. Fonctionne aussi très bien sur les tâches post-acné. ### 5.0/5 · Lalvenhimi Khiangte · September 9, 2025 Since I easily get acne scars, I have tried a lot of different viral products, but this one is definitely the best so far.
