ISDIN Retinal Intense Serum is a nighttime renewal serum designed to improve skin texture, smooth the appearance of fine lines, and support overall skin renewal while you sleep. It is ideal for adults noticing early or visible signs of ageing, uneven texture, dullness, or loss of firmness, especially those ready to introduce a stronger vitamin A–based skincare step into their routine.

This formula uses retinaldehyde, a more advanced form of vitamin A that works faster on the skin compared to traditional retinol, while still being well-tolerated when used correctly. It helps accelerate skin renewal with less discomfort for many users when introduced gradually.

With consistent nighttime use, skin may appear smoother, more even, and refined. Many users notice improved texture, reduced look of wrinkles, and a healthier glow as the skin renewal cycle becomes more efficient. The formula also aims to minimise dryness commonly linked with vitamin A products.

The serum combines retinaldehyde for renewal, bakuchiol for retinol-like smoothing support, melatonin for antioxidant protection during nighttime repair, and niacinamide to help calm and balance the skin. These ingredients work together to support smoother and more resilient-looking skin.

It can be suitable for sensitive skin if introduced slowly. The inclusion of soothing ingredients like niacinamide helps improve comfort, but beginners should start witth limited weekly use to allow the skin to adjust.

Yes, lightweight textures and renewal-focused ingredients can help improve uneven texture and the appearance of clogged pores over time. Many people with oily or combination skin appreciate its fast-absorbing feel.

Dry skin can benefit from the smoothing and renewal effects, but it is important to pair it with a nourishing moisturiser to maintain hydration and reduce the chance of dryness during the adjustment phase.

This serum works best as part of your nighttime skincare routine because vitamin A ingredients support overnight skin renewal. Apply it after cleansing and before moisturiser.

Dispense the recommended amount, mix the two phases until the texture looks uniform, and apply a thin layer on clean, dry skin while avoiding delicate areas like around the eyes and corners of the nose or mouth.

Start using it two to three nights per week and gradually increase frequency as your skin becomes comfortable. Slow introduction helps improve tolerance and reduces irritation risk.

It pairs well with gentle hydrating products and barrier supporting moisturisers. Strong exfoliating acids or other potent actives are usually better used at different times to avoid overwhelming the skin.

Yes, daily sunscreen is essential because vitamin A–based products can make skin more sensitive to sunlight. Protecting the skin helps maintain results and prevents irritation.

Many users begin noticing smoother texture and improved radiance within a few weeks, while more visible refinement in fine lines and overall skin appearance typically develops with continued consistent use.

Yes, but it is better suited for beginners who are ready to move beyond basic skincare and are willing to introduce active ingredients gradually with proper moisturising and sun protection.

Not at all. While it is popular for improving the look of wrinkles, it can also help people dealing with uneven texture, dull skin, or roughness who want a more refined and refreshed appearance.
