Best Polyglutamic acid products on Amazon India

Polyglutamic acid is a water-binding polymer used as a topical humectant. It is different from exfoliating acids: a PGA serum is generally designed to support surface hydration rather than exfoliate.

What the evidence says

Useful context before shopping

PGA can form a moisture-retaining film on the skin surface. Consumer claims comparing it directly with hyaluronic acid often rely on ingredient marketing rather than head-to-head clinical outcomes, so formula texture and supporting ingredients matter more than dramatic percentage claims.

How to use it

Safety notes

Pause before adding to cart

  • PGA is not an exfoliating treatment despite the word 'acid'.
  • Very tacky formulas can pill under sunscreen; use less product or allow layers to set.
  • Patch test the complete product because preservatives and fragrance can still irritate.
