My Doctor's Diagnosis: Analysis and Target

Green Keratin RTN-X SERUM by Green Keratin is primarily intended for skin showing signs of aging, including wrinkles, loss of firmness, and lack of radiance. Its formula, rich in innovative active ingredients, aims to stimulate cell renewal and improve skin texture. My expert opinion is that this serum falls into the category of advanced anti-aging skincare, while also providing a soothing and moisturizing effect, making it suitable for sensitive skin or skin prone to discomfort.

Formula Analysis: Key Assets

Three active ingredients stand out in this serum:

• Retinol : A powerful derivative of vitamin A, it stimulates collagen production, accelerates cell renewal, and visibly reduces wrinkles and pigmentation spots. Its effectiveness is widely documented in dermatology.
• Psoralea corylifolia (Bakuchiol) : This plant extract is known for its retinol-like properties, but with better skin tolerance. It works synergistically to enhance anti-aging action while limiting irritation.
• Hyaluronic acid (Sodium Hyaluronate) This benchmark moisturizing active ingredient captures and retains water in the skin, instantly plumping up the tissue and improving skin suppleness.

The presence of bisabolol and beta-glucan provides a soothing and restorative effect, ideal for limiting intolerance reactions.

Tips and Application Ritual

I recommend applying this serum in the evening, on clean, dry skin, before your moisturizer. It is best to avoid combining it with other powerful exfoliating active ingredients (AHAs, BHAs) to limit the risk of irritation. It can be combined with moisturizing or soothing skincare products, but you should avoid direct sun exposure after application and use sunscreen in the morning.

My Final Verdict & Safety Opinion

This serum stands out thanks to the synergy between retinol and bakuchiol, offering enhanced anti-aging effectiveness with good tolerance. Its light, non-greasy texture makes it easy to apply. One slight drawback: the presence of fragrance or potential allergens may not be suitable for ultra-reactive skin. In conclusion, this is a high-performance skincare product that should be gradually incorporated into your evening routine to optimize results while preserving the skin barrier.
