Distinguish hydration, exfoliation, retinoids and antioxidants, with realistic expectations.
Core ideas before application
Is hyaluronic acid an exfoliant like glycolic acid?
No; its main role here is hydration. The word acid does not assign every ingredient the same skincare function.
Does vitamin C remove the need for sunscreen?
No. An antioxidant is not equivalent to a tested sunscreen.
This molecular model identifies ascorbic acid. It does not represent every vitamin C derivative or establish a serum’s stability or efficacy.

What is the key retinoid rule during pregnancy?
Avoid them and discuss alternatives with a clinician. Pregnancy requires an appropriate choice, not merely reduced stinging.
Does the word peptides guarantee a result?
No; identity, formula and evidence matter. Peptides are a group, not one substance with fixed performance.
