Skin Care Guide
If a new skin care product leaves your face stinging or red, start with the timing and your skin’s response before adding another product. Mason Clinic explains what to prepare for a consultation.
Hello from Mason Clinic.
“I switched to a highly recommended product, but now my face stings.”
It is easy to wonder whether you need more moisture or a different product. Adding another step can feel like the next thing to try.
Let’s look at how to organise your symptoms and product history before deciding what your skin needs.

Stinging alone does not establish that a product is effective or that your skin barrier is damaged. Irritation, allergy and other possibilities need clinical assessment.
If you suspect a reaction to a new cosmetic, stop using it and gently wash it off. Prescription skin medication is different: ask the prescribing clinician whether to change its use.
Note when you started, how often you applied it and which products you layered with it. Did stinging begin immediately, or did itching or redness appear later?
If you changed several products together, list all of them. Avoid deciding in advance that only one must be responsible.
Instead of adding new masks or exfoliants, avoid products you suspect are irritating your skin. Give abrasive washing and repeated scrubbing a break.
Check how your skin responds to moisturiser, too. A moisturiser can also cause a reaction. If it keeps stinging, stop using that product and ask a clinician for help choosing one.
“Natural,” “unscented” and “for sensitive skin” do not guarantee that a product will suit you. Keep the ingredient list alongside your actual experience.
Save a photograph of the packaging or ingredients. Do not reapply a product that caused a reaction to your face to test the cause.

If you have booked skin care or a procedure, tell the clinic about new redness, itching or stinging beforehand. Whether to proceed may need to be reconsidered after assessment.
One reaction does not establish a need for a particular procedure. Assess the current problem before considering additional cosmetic care.
Persistent or recurring symptoms need assessment. Rapid worsening, discharge, increasing pain, fever or chills call for prompt medical attention.
Sudden swelling of the lips, tongue or throat, or trouble breathing, needs emergency help rather than a routine appointment. In Korea, call 119 immediately.
Your next step may be to organise what you used, when you used it and what changed. Bring that record so the consultation can consider both your routine and your current skin.
Mason Clinic follows the principle of “only what is needed, in the amount needed” when discussing skin concerns and everyday care.
