The INKEY List PHA Facial Toner 100ml
Not all exfoliants are the same — and if your skin is sensitive, dry, or has a compromised barrier, a high-strength AHA like Glycolic Acid can do more harm than good. The INKEY List PHA Facial Toner 100ml is built differently. PHAs (polyhydroxy acids) are the next generation of chemical exfoliants: larger molecules than AHAs mean slower, gentler penetration, with the added bonus of humectant properties that draw moisture into the skin as they exfoliate. The result is a toner that refines and exfoliates without stripping — making it the right choice for sensitive, dry, or reactive skin types who still want the benefits of chemical exfoliation.

Exfoliate Without Irritation: The INKEY List PHA Facial Toner 100ml
Chemical exfoliation doesn't have to come with stinging, redness or a recovery period. PHAs — polyhydroxy acids — are the gentlest family of exfoliating acids, and The INKEY List PHA Facial Toner 100ml harnesses their unique dual action: they exfoliate dead skin cells while simultaneously attracting moisture to the skin. Unlike AHAs such as Glycolic Acid, PHAs have a larger molecular size, meaning they work more slowly and superficially — which is precisely what sensitive, dry and reactive skin types need.
This is the exfoliating toner for anyone who wants clearer texture, smoother skin and healthier pores — without the harshness of higher-strength acids. It can be used daily, morning or evening, and is gentle enough even for those with a compromised skin barrier.
PHA vs AHA: Choosing the Right Exfoliant
If you've used Glycolic Acid and found it too intense, PHA is the natural alternative. It exfoliates progressively and gently, and its humectant properties mean it hydrates at the same time — making it especially well suited to dry skin or skin going through a reactive phase.

Barrier-Supportive Exfoliation
PHAs are one of the few exfoliating acids that may actually support the skin barrier rather than compromise it. For those managing acne and breakouts alongside barrier sensitivity, this toner offers a balanced approach — clearing without stripping.
How to Use
- After cleansing, sweep across face and neck with a cotton pad. Do not rinse.
- Suitable for morning and/or evening use.
- Follow with moisturiser. Apply SPF every morning without exception.
The INKEY List is a UK ingredient-led brand — they put the science first, explain every ingredient honestly, and keep prices accessible.
Usage & Benefits
- Gentle chemical exfoliation — PHAs (polyhydroxy acids) loosen and remove dead skin cells with significantly less irritation risk than AHAs like Glycolic Acid
- Hydrates while it exfoliates — PHAs are humectants, meaning they attract water to the skin as they work — unique among exfoliating acids
- Strengthens the skin barrier — PHA is associated with improved barrier function, protecting skin from moisture loss and environmental triggers
- Smooths skin texture — regular use refines rough texture and dullness without the harshness of stronger acids
- Reduces the appearance of pores — gentle clearing of congestion leads to visibly cleaner, tighter-looking pores
- Suitable for all skin types — especially beneficial for sensitive, dry, rosacea-prone or eczema-prone skin that cannot tolerate AHAs
- Beginner-friendly exfoliant — ideal for those new to chemical exfoliation or who have had negative reactions to Glycolic or Lactic Acid
- Can be used morning or evening — gentleness allows for flexible use within a routine
How To Use
1. Cleanse your face as usual.
2. Saturate a cotton pad with the PHA Toner.
3. Sweep gently across face and neck, avoiding the eye area.
4. Do not rinse — this is a leave-on toner.
5. Allow to absorb for 5 minutes, then apply serum and moisturiser as usual.
6. Can be used morning and/or evening — its gentleness makes twice-daily use suitable for most skin types.
7. Apply SPF every morning — PHAs do increase photosensitivity, though less than AHAs.
Tip: If transitioning from no chemical exfoliation, begin with every other day and increase as your skin acclimates. There is no rush — consistency matters more than frequency.
FAQs
What are PHAs and how are they different from AHAs like Glycolic Acid?
PHAs (polyhydroxy acids) are the newest generation of chemical exfoliating acids. They have a larger molecular structure than AHAs (alpha-hydroxy acids like Glycolic or Lactic Acid), which means they penetrate the skin more slowly and with less depth. This makes them significantly gentler and less likely to cause stinging, redness or irritation. The key additional difference: PHAs are also humectants, so they attract moisture to the skin as they exfoliate — AHAs do not do this.
Who should use PHA toner instead of Glycolic Acid toner?
Anyone with sensitive, dry, reactive, rosacea-prone or eczema-prone skin. If you have tried AHA toners and experienced excessive stinging, prolonged redness, or barrier disruption, switching to a PHA toner is the recommended step down. PHA delivers similar (though more gradual) exfoliation benefits without the same irritation risk.
Can I use PHA toner every day?
Yes — PHAs are gentle enough for daily, even twice-daily use for most people. This is a significant advantage over higher-strength AHAs like Glycolic Acid, which typically require a tolerance-building schedule.
Will PHA toner give me the same results as Glycolic Acid?
PHA exfoliates more gently and gradually — so results develop more slowly. Glycolic Acid's smaller molecule penetrates more deeply and typically delivers faster, more dramatic texture changes. PHA is the right trade-off if your skin cannot tolerate that intensity.
Do I still need to wear SPF when using PHA?
Yes. Although PHAs increase photosensitivity less than AHAs, they still remove surface cells and make skin more vulnerable to UV damage. Always apply SPF every morning.
