Acne Care While Breastfeeding.

To whom it may concern: I am currently breastfeeding and I have cystic acne on my chin and forhead. I don’t want to take oral medication and I am not sure which topical products are safe to use. I would like to use the Renee Rouleau Anti-Cyst Treatment. I contacted Renee Rouleau Customer Service and they said they believe it would be safe to use, but it would be best to check with my doctor. I live in Japan and my dermatologist is Japanese so I do not think it woukd be easy for him to determine this since all the ingredients are listed in English. Could someone one of your skin doctors possibly let me know if this product is safe to use while breastfeeding? The ingredients of the Anti-Cyst Treatment are as follows: Ethyl Lactate Methyl Gluceth 20 Citric Acid If there are any specific ingredients I need to avoid, it would be great if you could let me know that as well. Thank you!
