Regenerist Retinol24 Night Moisturizer
While formulated with beneficial Niacinamide, the use of a jar container is a significant flaw as it exposes the photosensitive retinoids to air and light, leading to rapid degradation. Furthermore, the brand uses a vague 'Retinoid Complex' label without disclosing the specific percentage of Retinol, making it difficult to gauge its actual potency compared to clinical-grade alternatives.
