🔬 1. Weak or compromised skin barrier The skin has a natural protective layer (called the skin barrier) made up of lipids and corneocytes. When this barrier is damaged (due to genetics,over-cleansing, misuse of skincare products...), the skin loses moisture easily and becomes more vulnerable to irritating substances in cosmetics. ⚖️ 2. Naturally sensitive skin Some people are born with sensitive skin. This skin type reacts easily to temperature changes,cosmetic ingredients,or even environmental factors. Symptoms: redness, burning,itching,stinging,or flaking after using a product. 🧴 3. Irritating ingredients in skincare products Some common ingredients can cause irritation for certain skin types: Alcohol Fragrance Strong essential oils Preservatives (e.g.,parabens, formaldehyde) High concentrations of AHA/BHA,especially if the skin is not used to them 🧬 4. Allergic reactions or ingredient incompatibility Irritation may not always mean sensitivity;it could be an allergic reaction to a specific ingredient. For example: allergies to Niacinamide,Retinol,or synthetic fragrances. ⏳ 5. Skin under treatment or damage Skin after procedures like peeling, laser,or acne treatments is usually more fragile and prone to irritation. It needs gentler,specially formulated skincare products. 💡 Advice from LA’BELLA BEAUTE SG Skincare Experts: If your skin often reacts to cosmetics,try the following: 1. Always do a patch test before applying products to the entire face. 2. Choose skincare for sensitive skin,free from fragrance,alcohol, and parabens. __________Love🥰
