My Doctor's Diagnosis: Analysis and Target

Green Keratin #RTN 0.75% night serum is primarily intended for skin showing signs of aging, such as wrinkles, fine lines, and loss of firmness. The presence of retinol at 0.75% positions this Green Keratin brand product as an expert skincare treatment, specifically formulated to stimulate cell renewal and improve skin texture. Its fragrance-free formula makes it particularly suitable for sensitive or reactive skin, while effectively targeting skin aging issues.

Formula Analysis: Key Assets

Three major active ingredients stand out in this serum:

• Retinol (0.75%) : A powerful derivative of vitamin A, it accelerates cell renewal, stimulates collagen production, and visibly reduces wrinkles and pigmentation spots. Its effectiveness is widely documented in dermatology for the prevention and correction of signs of aging.
• Hyaluronic acid (Sodium Hyaluronate) : This active ingredient intensely hydrates the skin, improves its elasticity, and counteracts the potentially drying effect of retinol, ensuring comfort and suppleness.
• Bisabolol and chamomile/calendula extracts These soothing agents reduce inflammation and the risk of irritation, making the formula more tolerable even for sensitive skin.

The synergy of these active ingredients gives the product anti-aging effectiveness while preserving the skin barrier.

Tips and Application Ritual

I recommend applying this serum in the evening to clean, dry skin, avoiding the eye area. It is best to start by applying it every other night, then gradually increase the frequency depending on tolerance. This serum is compatible with simple moisturizers, but it is not recommended to combine it with other irritating active ingredients such as AHA/BHA or pure vitamin C in the same routine.

My Final Verdict & Safety Opinion

This Green Keratin serum stands out for its balance between anti-aging effectiveness and skin tolerance, thanks to the combination of retinol, moisturizing and soothing agents. The absence of fragrance limits the risk of allergies. The only possible downside is a slight feeling of dryness or irritation in very sensitive skin, which should be monitored during the first few uses. My opinion: an excellent choice for a nighttime anti-aging routine, provided it is introduced gradually.
