Is this set suitable for sensitive skin, and how do I patch test it?

Both formulas lean on gentle, hydration-oriented ingredients such as aloe vera, chamomile and a green tea infusion, without harsh exfoliating acids or strong actives, which generally makes this kind of duo a reasonable choice for skin that dislikes aggressive products. Still, two precautions are worth taking:

• Check the full ingredient list on the packaging against your known sensitivities. Note in particular that the day cream contains almond oil — relevant if you react to nut-derived oils — and plant extracts like chamomile can occasionally trigger reactions in people sensitive to that botanical family.
• Do a patch test before first full use. Apply a small amount of each cream to the inner forearm or behind the ear, leave it for 24–48 hours, and watch for redness, itching or stinging. Test the eye cream separately on the skin near (not on) the eye area once the forearm test is clear, since eyelid skin can react to products the rest of the face tolerates.

If irritation appears, stop using the product. Both creams are for external use only, and the eye cream should stay on the contour rather than getting into the eyes. If you have a diagnosed skin condition or are under dermatological treatment, it makes sense to check with your specialist before adding new cosmetics to your routine.
