ISDIN Retinal Intense Serum | Antiwrinkle ISDINCEUTICS Retinaldehyde Serum | 50 ml

How ISDIN Retinal Intense Works

ISDIN Retinal Intense uses a two-phase serum technology that mixes at the moment of application to preserve the stability of sensitive active ingredients like retinal.

The formula works through multiple mechanisms:

Skin renewal stimulation

Retinaldehyde (a direct vitamin A derivative) accelerates epidermal turnover and supports collagen production.

Overnight antioxidant repair

Melatonin helps neutralize oxidative stress accumulated during the day and supports nighttime skin recovery.

Retinol-like activity with improved tolerance

Bakuchiol enhances anti-aging performance while helping reduce irritation and dryness.

Barrier strengthening and tone improvement

Niacinamide helps improve skin hydration, reduce redness, and promote a more even skin tone.

The result is smoother, firmer, and more radiant skin with improved texture and reduced wrinkles.

Advanced Retinaldehyde Technology for Nighttime Skin Renewal

ISDIN Retinal Intense is developed as a biphasic anti-aging night serum designed to support the skin’s natural renewal cycle. The formula combines retinaldehyde with melatonin in a patented combination, helping improve the appearance of wrinkles, texture, and overall skin tone while maintaining good skin tolerance.

Retinaldehyde is a vitamin A derivative known for its ability to stimulate epidermal renewal and collagen support, two essential mechanisms involved in smoother and younger-looking skin. Through regular nighttime use, the serum helps refine skin texture and improve the visible signs of skin aging.

Biphasic Serum System for Active Ingredient Stability

A distinctive feature of ISDIN Retinal Intense is its two-phase serum technology. The formula is separated into two phases that combine at the moment of application.

This system helps maintain the stability of sensitive ingredients such as retinaldehyde until the product is dispensed. Once mixed, the serum creates a lightweight texture that spreads evenly across the skin and absorbs smoothly without leaving a heavy residue.

The biphasic system is designed to ensure that the active ingredients remain effective throughout the product’s use.

Balanced Anti-Aging Formula with Retinal, Melatonin, and Bakuchiol

The formula of ISDIN Retinal Intense combines multiple dermatological ingredients that work together to support skin renewal and improve visible signs of aging.

Retinaldehyde acts as the main vitamin A ingredient, promoting smoother skin and helping reduce the appearance of wrinkles. Melatonin contributes antioxidant support that helps protect skin from oxidative stress and supports the nighttime skin recovery process.

Bakuchiol is included in the formula as a plant-derived ingredient known for its retinol-like properties. It helps improve skin firmness and elasticity while supporting better tolerance for vitamin A derivatives.

Niacinamide is also present to help strengthen the skin barrier, improve hydration, and promote a more even and radiant complexion.

Texture and Finish on the Skin

Once the two phases are mixed, the serum forms a silky, lightweight texture designed for nighttime use. The formula spreads easily across the skin and absorbs smoothly without leaving a greasy film.

This allows the product to be integrated comfortably into a night skincare routine while delivering active ingredients that support overnight skin renewal.

With consistent use, ISDIN Retinal Intense helps promote smoother, softer, and more refined-looking skin.
