My Doctor's Diagnosis: Analysis and Target

Visit Isana Overnight Moisture Serum of the brand Isana is primarily intended for skin that lacks moisture, is prone to dehydration, or feels uncomfortable, especially after cleansing or during periods of skin stress. Its formula aims to restore the skin barrier and provide intense hydration during the night, a key time when the skin regenerates. My expert opinion is that this serum is part of a preventive and restorative skincare routine, ideal for tired, dull skin or skin exposed to external aggressions.

Formula Analysis: Key Assets

Three major active ingredients stand out in this formula:

• Glycerine : A powerful humectant, it attracts and retains water in the epidermis, promoting long-lasting hydration and a visible plumping effect.
• Niacinamide (Vitamin B3) : This multifunctional ingredient improves barrier function, reduces redness, and evens out skin tone. It also helps regulate sebum and reduce blemishes.
• Lactic Acid : This gentle AHA promotes mild exfoliation, stimulates cell renewal, and improves skin texture without damaging it.

The synergy of these active ingredients guarantees optimal hydration, smoother skin, and a radiant complexion. The presence of sugars (xylitol, glucose) enhances the moisturizing and protective effect.

Tips and Application Ritual

I recommend applying this serum in the evening, on clean, dry skin, before your night cream. It can be used alone or in combination with other moisturizers. It is compatible with most active ingredients, but I do not recommend combining it with powerful exfoliants (retinoids, other AHAs/BHAs) to avoid irritation. It is ideal for use in combination with soothing or repairing skincare products.

My Final Verdict & Safety Opinion

This serum stands out for its light, non-greasy texture and excellent tolerance. Its strengths lie in its moisturizing effectiveness and its ability to improve skin quality from the very first applications. A slight drawback could be the presence of fragrance or preservatives for ultra-sensitive skin, but the formula remains safe overall and suitable for daily use. In conclusion, it is an excellent choice for restoring nighttime hydration and strengthening the skin barrier.
