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.

- Apply a small amount to slightly damp skin after cleansing.
- Follow with moisturiser to reduce water loss, especially in dry or air-conditioned environments.
- Use once or twice daily according to the formula and your tolerance.
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.
