PHA (gluconolactone)
PHAs such as gluconolactone are gentle exfoliants with a larger molecule, so they work slowly at the surface and are less likely to sting.
PHA (gluconolactone) at a glance
- What it does
- They also attract water, so they hydrate while they exfoliate. A sensible first acid.
- Who it suits
- Sensitive and dry skin, and anyone new to acids.
- Who should be careful
- Gentle is not the same as zero. Use daily sunscreen and start a few times a week.
- AM or PM
- Morning or night. Most people use it in the evening.
- Don’t layer with
- Retinol and retinal: Best split AM and PM, or on different nights. PHA is gentle, but keep it to different nights while your skin adjusts to retinol.
- Glycolic and lactic acid (AHA): Best split AM and PM, or on different nights. Both exfoliate. Pick one per routine.
