The Ordinary PHA 5% Exfoliating Lip Serum - 15ml

You can use this serum once or twice daily, depending on your lip's needs and sensitivity. For best results, consistent daily use is recommended.

Yes, this serum is formulated with PHA (polyhydroxy acid), which is known for its gentler exfoliating properties compared to other acids, making it suitable for sensitive skin. However, always perform a patch test first.

PHA stands for Polyhydroxy Acid, specifically Gluconolactone in this product. It's a gentle chemical exfoliant with a larger molecular size, meaning it exfoliates the surface of the skin without penetrating too deeply, making it less irritating. It helps to remove dead skin cells, improve texture, and enhance brightness.

The slightly tangy taste comes from the exfoliating acids (PHAs) present in the formula. This is a normal characteristic of the product and indicates its active ingredients are at work to gently renew and smooth your lips.

Absolutely! For optimal results, apply the serum to clean, dry lips first and allow it to absorb for a minute or two. Afterwards, you can follow with your favorite lip balm, lipstick, or any other lip treatment.

No, The Ordinary PHA 5% Exfoliating Lip Serum does not contain SPF and does not offer sun protection. It is recommended to use a lip balm with SPF during the day if you are exposed to the sun.

A small, pea-sized amount is generally sufficient for both lips. Start with less and adjust as needed. Over-applying will not necessarily yield better results and might lead to stickiness.

Ensure consistent daily use, especially before bed. Consider applying a richer, occlusive lip balm over the serum after it has absorbed to lock in moisture effectively. You might also need to increase water intake throughout the day.

This taste is a natural characteristic of the PHA. Try applying a smaller amount of the serum, or use it primarily at night when you are less likely to notice it. The taste should dissipate shortly after application.

While designed for sensitive skin, some initial tingling is normal. If irritation persists or becomes uncomfortable, reduce usage frequency to every other day or a few times a week until your lips adjust. Discontinue use if severe irritation occurs.

Allow adequate time for the product to work; results may not be immediate. Consistent daily use for at least 2-4 weeks is often needed to see significant improvements in texture and brightness. Ensure your lips are clean before application.
