My Doctor's Diagnosis: Analysis and Target

Green Keratin C20 Lipid Serum primarily targets the fight against skin aging, particularly wrinkles, dullness, and loss of firmness. The Green Keratin brand offers a formula focused on revitalizing and protecting the skin, suitable for mature, dull skin or skin exposed to oxidative stress. My expert opinion is that this serum is for anyone looking for powerful antioxidant action and a visible improvement in skin texture, while preserving hydration and the lipid barrier.

Formula Analysis: Key Assets

Three active ingredients stand out in this formula:

• Tetrahexyldecyl Ascorbate : A fat-soluble derivative of vitamin C, it effectively penetrates the skin to stimulate collagen synthesis, reduce pigmentation spots, and provide antioxidant protection against free radicals.
• Glutathione : A major antioxidant, it works in synergy with vitamin C to strengthen cellular defenses, limit oxidation, and promote a radiant complexion.
• Sodium Hyaluronate : A form of hyaluronic acid, it intensely hydrates, plumps the skin, and improves skin suppleness.

The presence of panthenol and saccharide isomerate complements the moisturizing and soothing action, making the formula particularly beneficial for dehydrated or sensitive skin.

Tips and Application Ritual

I prefer to apply this serum in the morning, on clean, dry skin, before moisturizer and sunscreen. It is compatible with most moisturizing active ingredients (hyaluronic acid, ceramides), but I recommend avoiding immediate combination with powerful exfoliating acids (AHA/BHA) to preserve the stability of vitamin C. It can also be used in the evening for enhanced repair action.

My Final Verdict & Safety Opinion

This serum stands out for its high concentration of stabilized vitamin C and its intelligent combination of antioxidants and moisturizing agents. Its lipid texture promotes the penetration of active ingredients without leaving a persistent greasy effect. The only possible drawback is the presence of colorants, which may not be suitable for ultra-sensitive skin. In conclusion, this is an expert, safe, and effective treatment for revitalizing and protecting the skin on a daily basis.
