My Doctor's Diagnosis: Analysis and Target
Green Keratin #RTN CAP 0.5% night serum is primarily intended for skin showing signs of aging, such as wrinkles, loss of firmness, and uneven texture. The presence of retinol at 0.5% positions this Green Keratin brand product as an expert skincare treatment, specifically formulated to stimulate cell renewal and improve skin quality overnight. In my opinion, the fragrance-free formula limits the risk of irritation and is suitable for sensitive skin types seeking effective anti-aging action.
Formula Analysis: Key Assets
Three major active ingredients stand out in this serum:
- Retinol (0.5%) : A powerful derivative of vitamin A, it accelerates cell renewal, stimulates collagen production, and reduces wrinkles and pigmentation spots. Its effectiveness is widely documented in dermatology for the treatment of skin aging.
- Hyaluronic acid (Sodium Hyaluronate) This active ingredient intensely hydrates the skin by retaining water in the dermis, which improves elasticity and plumps up surface wrinkles.
- Grape seed extract (Vitis Vinifera Seed Extract) Rich in antioxidant polyphenols, it protects the skin from oxidative stress and strengthens the skin barrier.
The synergy of these active ingredients gives the product a comprehensive anti-aging, moisturizing, and protective effect.
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 irritating active ingredients such as AHAs/BHAs or pure vitamin C in the same routine. However, it is compatible with moisturizing or soothing skincare products (hyaluronic acid, ceramides).
My Final Verdict & Safety Opinion
This Green Keratin serum stands out for its anti-aging effectiveness, fragrance-free formula, and proven active ingredients. One possible downside: the texture may be too rich for oily skin, and the retinol may cause slight irritation at first. My opinion: an excellent choice for an anti-aging nighttime routine, to be introduced gradually.
