The Ordinary PHA 5% Exfoliating Lip Serum: Overnight Hydration and Gentle Lip Exfoliation (15ml)
Product description
What it is
The Ordinary PHA 5% Exfoliating Lip Serum is a lip treatment designed to smooth and hydrate the lips. It combines a gentle chemical exfoliant based on 5% polyhydroxy acid (gluconolactone) with hydrating overnight appeal, aimed at improving texture while keeping the lips comfortable through the night.
How it works

On the surface, gluconolactone acts as a PHA to gently exfoliate without the aggressive feel of harsher acids. This makes it suitable for lip care where sensitivity is a concern. The formulation is focused on smoothing away dry or flaky skin and helping the lips feel more moisturised as you wake.
Who it’s for
If you’re looking for a low‑maintenance lip exfoliant that isn’t aggressive, this product is positioned for daily life where you want a subtle improvement in texture. It may appeal to those who prefer a lightweight, hydrating finish after exfoliation and want to avoid heavy balms during the night.



The advantages
The key point is its gentle approach: a 5% PHA exfoliant that targets surface texture while incorporating hydrating elements. On paper, this combination can deliver smoother lips without pronounced irritation. It’s relatively straightforward to incorporate into a nighttime routine and does not require mechanical scrubbing.
The limitations

Not every lip concern will be solved by a chemical exfoliant alone. If your lips are severelydry or cracked, or if you expect dramatic immediate results, this product may feel modest in impact. There is no information here about scent, texture feel, or long‑term durability of results, so results can vary. Also, guidance on how often to use it isn’t stated, which means you’ll need to assess comfort and comfort over time.
Practical use tips
Apply a thin layer to the lips as part of a night routine. Because it’s designed for overnight use, you might notice the texture improving by morning, though initial days may feel subtle. If you usually wear lip products to bed, consider how this serum sits beneath them and adjust usage accordingly. A small amount tends to go a long way, so start conservatively and observe how your lips respond.



How it compares to alternatives
This is a gentler option for lip exfoliation compared with harsher chemical or mechanical scrubs. If you prioritise everyday comfort and a non‑abrasive approach, it sits closer to a maintenance step rather than a dramatic corrective treatment. In contexts where more intensive exfoliation is required, a different formulation or applied frequency might be more appropriate.
What to check before buying

- Confirm your lip care goals: light textural improvement versus a more intensive exfoliation.
- Consider whether you want a product that also emphasises overnight hydration.
- Look for any guidance on usage frequency to tailor it to your routine.
- Pay attention to how you react to gluconolactone if you have sensitive or reactive skin.
Is it worth it?
It makes sense if you prioritise a mild, overnight exfoliation that also aims to hydrate. If your lips respond better to heavier exfoliants or you need noticeable fast results, you might want to consider alternatives or adjust expectations accordingly.



FAQ
- What is the main exfoliating ingredient? Gluconolactone at 5% (a Polyhydroxy Acid).
- Is it an overnight treatment? Yes, it’s described as an overnight lip exfoliator.
- Can I use it every night? The available information does not specify frequency, start with a cautious approach and monitor tolerance.
- Will it replace a balm? It aims to smooth texture, you may still want a lip balm for routine hydration.
Final thought
If you’re after a gentle, low‑risk way to refresh lip texture while keeping lips hydrated, this product offers a straightforward approach. It may not be the strongest option for those needing dramatic exfoliation or for those with very sensitive lips seeking no sensation at all.
Decision point
Is it worth it? Worth considering if you favour gentle, overnight exfoliation with hydration. Not the best match if you need aggressive exfoliation or have unmet sensitivity concerns.
