Lovi Assistant explains
- Excellent suitability for your oily skin is provided by glycolic acid and retinol, which effectively exfoliate and regulate oil production, complemented by niacinamide for enhanced oil control and barrier support.
- The serum offers moderate exfoliation for your acne, blemishes, and breakouts due to the resurfacing and pore-clearing properties of glycolic acid and retinol.
- The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of harsh ingredients and the presence of soothing components like niacinamide and allantoin.
How to apply
- Could be used as part of your PM routine. Start 3 times a week and build up to daily use if your skin tolerates it well.
- Apply your serum after cleansing and toning, but before putting on your moisturizer.
- Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on clean, dry skin to help manage your blemishes safely.
- Do a patch test before your first use and avoid the delicate eye area.

Questions and answers
What makes Peter Thomas Roth Even Smoother Glycolic Retinol Resurfacing Serum a great fit for oily acne-prone skin?
This serum is a great fit because glycolic acid and retinol help exfoliate and control oil, while niacinamide supports your skin barrier. It also helps clear pores and reduce blemishes without causing irritation, thanks to soothing ingredients like allantoin.
Journal of Cosmetic Dermatology, 2019Clinical, Cosmetic and Investigational Dermatology, 2019
Which ingredients make this serum a good fit for oily acne-prone skin?
Glycolic acid and retinol are the main ingredients that make this serum a great fit because they exfoliate the skin and help clear pores. Niacinamide also helps control oil and supports your skin barrier, while soothing components like allantoin keep your oily skin comfortable with a very low risk of irritation.
Journal of Cosmetic Dermatology, 2019Clinical, Cosmetic and Investigational Dermatology, 2019
What does Glycolic Acid do for oily acne-prone skin?
Glycolic acid helps clear breakouts and smooth oily skin by exfoliating dead surface cells. It may reduce both inflamed and non-inflamed blemishes when used regularly, though a product of this type also needs soothing ingredients like niacinamide or ceramides to keep skin calm and comfortable.
What does Retinol do for oily acne-prone skin?
Retinol helps clear breakouts and smooth oily skin by targeting clogged pores and reducing acne lesions. It is generally well tolerated, though an oily acne-prone routine needs ingredients that balance oil without causing irritation.
American Journal of Clinical Dermatology, 2019Journal of Drugs in Dermatology, 2018
Where does this serum go in a skincare routine for oily acne-prone skin?
This serum goes in your evening routine after cleansing and toning, and before applying your moisturizer. Lovi routines start exfoliating treatments once a week, and you can carefully use them more often if your skin tolerates them well.
Can I use this serum with BHA, and in what order?
You can use this serum with BHA by alternating the nights you apply them to avoid overwhelming your skin with too much exfoliation at once. Applying both at the same time may increase the likelihood of irritation, so it is best to use them on separate days or use BHA in the morning and this serum at night.
American Family Physician, 2012Clinical, Cosmetic and Investigational Dermatology, 2019
How often should I use this serum?
Start using this treatment serum once a week in the evening, and if your skin feels comfortable and results look good, you can carefully use it more often. Glycolic acid and retinol help clear pores and regulate oil, while niacinamide and allantoin keep irritation low.
Journal of Cosmetic Dermatology, 2024Journal of Cosmetic Dermatology, 2019
Can this serum clog pores, cause breakouts or purging for oily acne-prone skin?
This serum is unlikely to cause breakouts on oily skin, as it contains glycolic acid and retinol to help clear pores, along with soothing niacinamide and allantoin. Some reviewers do mention minor breakouts, and active ingredients like retinol may cause initial purging while clearing the skin.
Journal of Cosmetic Dermatology, 2019Clinical, Cosmetic and Investigational Dermatology, 2019
Is this serum fragrance-free and alcohol-free?
It has no fragrance and contains drying alcohol (alcohol).
