Isdin Isdinceutics Retinal Smooth – Biphasic Night Serum with Retinaldehyde

Reveal Radiant, Youthful Skin with Every Use

Isdin Isdinceutics Retinal Smooth is a cutting-edge biphasic night serum designed to prevent and correct the first signs of aging, including fine lines, uneven skin tone, and loss of luminosity. Formulated with retinaldehyde, a powerful form of Vitamin A, along with Matrikines, Niacinamide, and Melatonin, this innovative serum enhances skin renewal, repairs oxidative damage, and delivers intense hydration—all while you sleep.

With its unique biphasic technology, Retinal Smooth ensures that its potent active ingredients remain fresh and effective until the moment of application, providing a gentle yet powerful anti-aging action suitable even for sensitive skin.

Clinical studies show that after just four weeks of use:

• 40% increase in luminosity
• 52% reduction in visible pores
• 91% of users noticed fewer fine lines
• 100% of users reported no irritation and improved skin radiance

Why Choose Isdin Isdinceutics Retinal Smooth?

1. Gently Repairs and Renews the Skin: Retinaldehyde is a well-researched anti-aging powerhouse, known for its ability to stimulate cell turnover, reducing the appearance of fine lines and uneven skin tone while keeping skin smooth and hydrated. Unlike traditional retinoids, it works without excessive irritation, making it ideal for beginners or those with sensitive skin.
2. Enhances Skin Brightness and Luminosity: Thanks to the combined action of retinaldehyde and matrikines, Retinal Smooth revitalizes dull skin and enhances natural radiance. In just four weeks, users noticed a 40% increase in skin brightness.
3. Antioxidant Protection & Repair: This serum is enriched with melatonin, a powerful nighttime antioxidant that protects against oxidative stress, reduces free radical damage, and supports the skin’s natural repair process.
4. Strengthens & Soothes with Niacinamide: Niacinamide (Vitamin B3) is a multi-benefit ingredient that calms irritation, reinforces the skin’s barrier function, and boosts hydration. It is especially effective for reducing redness and improving overall skin texture.
5. Hydration for Comfort & Smoothness: Unlike many retinol-based products that cause dryness, Retinal Smooth’s formulation provides continuous hydration, keeping the skin nourished and comfortable throughout the night.
