Product Description
A gentle yet effective retinol formula designed for those beginning their retinol journey or with sensitivity concerns. Dr.Nuell No.5 combines 0.25% pure Retinol with a multi-layered Hyaluronic Acid complex and skin-calming actives — delivering the renewal benefits of retinol while actively supporting hydration and barrier integrity.
Formulated to minimize irritation without compromising efficacy, this serum works to improve skin texture, refine pores, and promote a smoother, more even-toned complexion over time.
Key Actives — Retinol 0.25% — promotes cell turnover and skin renewal — Niacinamide 20,000ppm — brightens, refines, and supports barrier function — Adenosine 400ppm — smooths the appearance of fine lines — Hyaluronic Acid + Hydrolyzed Hyaluronic Acid + Sodium Hyaluronate 100ppm each — multi-depth hydration — Aloe Barbadensis Leaf Extract — soothes and calms during the adjustment period
Suitable for: Sensitive skin | Allergen-free | Fragrance-free
How to Use
For first-time retinol users, apply every other day for the first two weeks before transitioning to nightly use. Apply in the evening after cleansing and toning. Follow with moisturizer.
As retinol increases photosensitivity, daily SPF application is essential.
Cautions
Some initial redness, dryness, or flaking may occur during the adjustment period. Avoid use alongside exfoliating scrubs, peeling treatments, or skin-stimulating devices.
For external use only. Avoid contact with eyes. Do not apply to broken skin or open wounds. Discontinue use if irritation persists and consult a healthcare provider.
Storage
Store in a cool, dry place away from direct sunlight and heat. Do not freeze.
