My Doctor's Diagnosis: Analysis and Target

Good Molecules' 5% Niacinamide with Ectoin serum is primarily intended for skin prone to blemishes, excess oil, enlarged pores, and dehydration. This product also aims to strengthen the skin barrier and improve radiance. Based on my analysis, Good Molecules' formulation is suitable for combination to oily skin, but also for sensitive skin types seeking to soothe and protect their epidermis. The 5% niacinamide concentration is optimal for visible effectiveness without the risk of irritation, demonstrating a balanced and skin-friendly approach.

Formula Analysis: Key Assets

Three active ingredients stand out in this serum. Niacinamide, or vitamin B3, regulates sebum production, tightens pores, and reduces redness thanks to its anti-inflammatory action. Ectoine, a naturally occurring amino acid, protects skin cells from environmental stress and strengthens the skin barrier, thereby limiting water loss. Finally, acetyl glucosamine works in synergy with niacinamide to improve skin tone uniformity and stimulate cell regeneration. The presence of glycerin and betaine completes the moisturizing effect, making the formula particularly suitable for dehydrated or sensitive skin.

Tips and Application Ritual

I recommend applying this serum in the morning and/or evening, on clean, dry skin, before your moisturizer. It fits perfectly into a minimalist routine or can be combined with gentle active ingredients such as hyaluronic acid. It is compatible with most skincare products, but I do not recommend combining it with powerful exfoliating acids (AHAs/BHAs) or retinol at the same time to avoid any risk of irritation.

My Final Verdict & Safety Opinion

This Good Molecules serum stands out for its short, effective, and well-tolerated formula. Its strengths lie in the synergy between niacinamide, ectoine, and moisturizing agents, offering comprehensive action on radiance, protection, and skin balance. Its light texture and fragrance-free formula make it a safe choice for sensitive skin. The only possible downside is a temporary sticky feeling for some users. My opinion as a doctor: an excellent ally for strengthening the skin on a daily basis.
