People Say
★4.7Overall rating based on 200+ reviewsUsers consistently describe this toner as a "facial in a bottle" specifically suited for mature, dry, or "devitalized" skin due to its vitamin-enriched formula. While gentler than the original P50, it is highly praised for effectively resurfacing texture and creating a "glass skin" glow without stripping moisture, though the application process requires tolerance for its potent scent and sensation.

The Australasian Journal of Dermatology, 1992BioMed Research International, 2020
What does Gluconolactone do for acne-prone skin?
Gluconolactone helps clear acne-prone skin by reducing both inflamed and non-inflamed blemishes. It is well tolerated and tends to cause fewer side effects than traditional treatments.
The Australasian Journal of Dermatology, 1992Clinical, Cosmetic and Investigational Dermatology, 2019
What does Niacinamide do for acne-prone skin?
Niacinamide helps acne-prone skin by reducing both inflamed and uninflamed breakouts and calming redness. It is also very helpful for keeping oily skin balanced by cutting down on excess oil production, and it is well tolerated by most people.
Where does this toner go in a skincare routine for acne-prone skin?
This exfoliating toner is used in the evening after your cleanser and before your treatment and moisturizer. Lovi routines start exfoliating products like this once a week, and you can carefully use it more often if your skin tolerates it well and sees good results.
Can I use this toner with retinol, and in what order?
You can use this toner with retinol by applying the toner first in your evening routine, but use them on alternate nights or space them out to keep your skin calm and minimize irritation. Combining too many strong active ingredients at once may lead to dryness and redness, so watch how your skin feels.
How often should I use this toner?
Start using this exfoliating toner once a week in your evening routine, and if your acne-prone skin tolerates it well and sees good results, you may carefully use it more often. It helps clear clogged pores and reduce breakouts while keeping irritation low.
Dermatologic Surgery, 2003Journal of Cosmetic Dermatology, 2021
Can this toner clog pores, cause breakouts or purging for acne-prone skin?
This toner is unlikely to clog pores or cause breakouts because it uses exfoliating acids and niacinamide to clear out congestion, calm inflammation, and regulate oil production. It may cause mild initial irritation or purging as it renews your skin, but soothing ingredients help keep that risk low.
The Australasian Journal of Dermatology, 1992BioMed Research International, 2020
Is this toner fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
