What should I be careful about when introducing this gel into my existing skincare routine?

If your skin is reactive, perform a patch test first by applying a small amount to a discreet area (like behind the ear or on the jawline) and monitor for 24 hours for any signs of redness, itching, or irritation—discontinue use if these occur. Avoid applying the gel directly to the eye area, as the skin there is more sensitive. Crucially, if you are already using other intensive anti-blemish products such as exfoliating acids (like salicylic or glycolic acid), retinoids, or prescription treatments, introduce this gel carefully to avoid overloading your skin. Consider using it on alternate days initially or applying it only in the morning if you use other actives at night. The goal is to support your skin's balance without causing dryness or sensitivity from too many active ingredients at once.
