Key Benefits How to Use Key Ingredients FAQ Soothes Sensitive & Reactive Skin: Calms redness, irritation, and discomfort associated with reactive or environmentally stressed skin. Restores Barrier Function: Lipid-rich actives replenish the skin's hydrolipidic barrier and reduce transepidermal water loss. Improves Softness & Elasticity: Regular use leaves the skin noticeably smoother, more supple, and better able to tolerate external aggressors. Antioxidant Protection: Defends against oxidative stress that exacerbates sensitivity and reactive responses. Apply a few drops to cleansed face and neck, massaging gently until fully absorbed. Follow with the recommended Mansard cream. Use morning and/or evening. Suitable for daily use. Glycine Soybean Oil: A nourishing emollient rich in essential fatty acids and phytosterols. Restores the lipid barrier, improves skin softness, and reduces transepidermal water loss. Squalane: A biomimetic lipid naturally found in skin sebum. Provides deep yet lightweight moisturization, improves elasticity, and reinforces the barrier without clogging pores. Blue Tansy: A powerful soothing and anti-inflammatory essential oil naturally rich in chamazulene. Calms redness, irritation, and reactive skin while supporting comfort and balance. What does "désensibilisant" mean? It means desensitizing — the serum is formulated to progressively reduce the skin's reactivity over time, helping it tolerate daily environmental stressors and skincare actives with less irritation and redness. Can I use this with other Mansard serums? Yes. It pairs well with Sérum N°24 Hydratation Cellulaire for a calming and hydrating protocol. If using multiple serums, apply this one first as it supports the barrier that allows subsequent actives to penetrate effectively. Is Blue Tansy safe for all skin types? Blue Tansy is well-tolerated by most skin types and is particularly beneficial for reactive, sensitive, or inflamed skin. At the concentrations used in professional skincare, it is non-irritating and non-photosensitizing. Can it be used on rosacea-prone skin? Its soothing and barrier-restoring profile makes it a suitable option for rosacea-prone skin. For more targeted rosacea care, pair with Crème Apaisante Sensitive N°1.
