Yes. Your DermClick account has a secure messaging channel that goes to your dermatologist's case queue, not a generic support inbox. Use it for clinical questions — unexpected reactions, application timing, layering with another product, a concern that has changed since your last review, a new medication you are starting that may interact with your formula.
For non-clinical questions — shipping, billing, account changes — use the standard support channel (phone, email, or the support form on your dashboard). Routing clinical questions through the dermatologist channel and operational questions through support keeps the response time fast for both.
