Use the product-specific label first
The safest starting point is the exact label on the product you have. Directions and warnings can differ even when products appear similar.
Check where the product should not be applied
Many topical labels restrict use around eyes or mucous membranes and on damaged or irritated skin. Do not assume a cream is suitable for every body area.
Heat and occlusion can change exposure
Heating pads, bandages or tightly covering a topical product can change skin exposure. If the label says not to combine the product with heat or bandaging, follow that instruction.
Be cautious when layering topical products
Using multiple creams, ointments or liniments on the same area can increase irritation or create combinations that have not been evaluated. Product-specific warnings should guide decisions.
Know when to stop
Persistent or worsening symptoms, unusual skin reactions or symptoms that exceed the product label’s self-care context are reasons to stop and seek appropriate professional advice rather than simply applying more product.
