My Doctor's Diagnosis: Analysis and Target

Green Keratin #RTN 1.0 night serum is primarily intended for skin showing signs of aging, such as wrinkles, loss of firmness, and uneven skin tone. The presence of retinol in the Green Keratin brand's formula positions this product as an expert anti-aging treatment, ideal for those seeking regenerating and smoothing action during the night. Its texture, enriched with plant oils and moisturizing agents, also makes it suitable for skin lacking comfort or nutrition, while remaining appropriate for a targeted nighttime routine.

Formula Analysis: Key Assets

Three major active ingredients stand out in this formula. The retinol, known for its effectiveness in stimulating cell renewal and collagen synthesis, acts deeply to reduce wrinkles and improve skin texture. The’sea buckthorn oil provides omega fatty acids and antioxidants, promoting skin repair and protection against oxidative stress. Finally, the sodium hyaluronate (hyaluronic acid) provides intense hydration, plumping the skin and strengthening the skin barrier. The combination of these active ingredients gives the product a comprehensive anti-aging, moisturizing, and repairing action, while respecting the skin's balance thanks to the absence of fragrance.

Tips and Application Ritual

I recommend applying this serum in the evening, on clean, dry skin, before your night cream. Due to the presence of retinol, it is best to avoid combining it with other potentially irritating active ingredients such as exfoliating acids (AHA/BHA) or pure vitamin C. It can be combined with moisturizing or soothing skincare products. It is essential to use sunscreen in the morning during the treatment.

My Final Verdict & Safety Opinion

This Green Keratin #RTN 1.0 serum stands out for its anti-aging effectiveness, fragrance-free formula, and rich content of repairing and moisturizing active ingredients. Its enveloping texture is suitable for normal to dry skin. One possible drawback: the presence of cotton oil, which can be comedogenic on oily or acne-prone skin. My opinion: a high-performance nighttime treatment that should be incorporated with caution into a suitable routine.
