I have very reactive skin — how should I test and use this balm? — After Shave Balm Active for Normal Skin with Panthenol "Top Ten", 75 ml - Rubella

If your skin reacts easily to new products, a cautious approach reduces the risk of a full-face flare-up. Apply a pea-sized amount to a small patch — for example, just under the jawline or on one cheek — after shaving and wait 15–20 minutes. If no stinging, redness, or itching develops, you can extend use to the whole shaved area. The product guidance notes to avoid the eye area and any broken skin (nicks, cuts, active breakouts) because even soothing ingredients can irritate compromised barrier zones. Use clean hands and apply to freshly rinsed, patted-dry skin; rubbing aggressively can itself trigger reactivity. If you use a separate moisturiser or sunscreen, let the balm absorb fully (usually under a minute) before layering. Should any irritation appear — persistent redness, burning, or a rash — discontinue use and consult a dermatologist or pharmacist. This product is a cosmetic for comfort and hydration; it is not a treatment for skin conditions such as eczema, psoriasis, or folliculitis.
