Can you use salicylic acid while pregnant?
Vessa leaves leave-on salicylic acid out during pregnancy. Guidance on low-strength topical BHA is more relaxed than on retinoids, but this is a question for your clinician rather than an app.
What Vessa does with both on your shelf
With pregnancy on the profile, salicylic acid is filtered out of every slot except cleansers, which rinse off.
Why
The app takes the cautious side of a genuinely mixed picture: rather than pick a threshold, it chooses something else and leaves the decision with you and your clinician.
When this is a question for a clinician
If your obstetrician or dermatologist has told you a specific product is fine, they know your pregnancy and this page does not.

How this answer is decided
These verdicts are the rules Vessa applies when it builds a routine, not an editorial opinion. The app schedules retinoids in the evening only, keeps exfoliants on different nights from them, puts vitamin C in the morning and sunscreen last every morning, and removes retinoids, salicylic acid and hydroquinone from consideration entirely when someone tells it they are pregnant or breastfeeding. Where the evidence is genuinely mixed, the app takes the cautious side and this page says so rather than picking one for you.
Vessa sells a subscription, not the products it recommends, and it suggests buying something only where a step is missing from what you already own. This is skincare guidance, not medical advice: anything painful, spreading or changing quickly belongs with a dermatologist.
