Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for smoothing texture, which is beneficial for your combination skin due to the presence of mandelic acid and glycerin for balancing oily and dry areas.
- While it provides general skincare benefits like hydration, these are not directly targeted at your acne, blemishes, and breakouts, as the mandelic acid and retinol offer mild exfoliation and cell turnover.
- The product is generally safe for your combination skin, with a low risk of irritation from mandelic acid and retinol.
How to apply
- Use your serum as part of your PM routine and start 3x/week before working up to daily use.
- Apply this treatment after cleansing and toner, and before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the product on clean, dry skin to help manage your breakouts safely.
- Avoid the eye area and do a patch test before your first use.

Questions and answers
How well does The INKEY List Mandelic Acid work for acne-prone skin?
The INKEY List Mandelic Acid Treatment works for acne-prone skin as an average fit because it offers mild exfoliation to smooth texture, though it is not directly targeted at blemishes and breakouts. A product for this skin needs effective ingredients like niacinamide, propolis, or zinc PCA that directly target acne and blemishes while providing balanced hydration without irritation.
Journal of Cosmetic Dermatology, 2020International Journal of Cosmetic Science, 2017
Which ingredients make this exfoliant a good fit for acne-prone skin?
Mandelic acid and retinol make this treatment a fit by offering mild exfoliation and cell turnover. To best care for acne-prone skin, this type of product needs ingredients like niacinamide, propolis, or zinc PCA that directly target breakouts and control oiliness.
Journal of Cosmetic Dermatology, 2020International Journal of Cosmetic Science, 2017
What does Mandelic Acid do for acne-prone skin?
Mandelic acid helps clear acne and smooth the skin by gently exfoliating and calming breakouts with fewer side effects than many other acids. It is unlikely to cause heavy irritation, and combining it with other treatments may improve stubborn acne and dark spots even further.
Journal of Cosmetic Dermatology, 2020Journal of Cosmetic Dermatology, 2022
What does Glycerin do for acne-prone skin?
Glycerin helps keep acne-prone skin hydrated and calm without clogging pores or feeling heavy. It supports the skin barrier so it stays soft and smooth while handling everyday treatments.
The British Journal of Dermatology, 2008International Journal of Toxicology, 2019
Where does it go in a skincare routine for acne-prone skin?
This treatment goes in the evening routine after cleansing and before moisturizing, starting once a week to see how your skin feels. To better target acne and breakouts, this skin type needs stronger ingredients like salicylic acid or benzoyl peroxide.
Can I use this exfoliant with niacinamide, and in what order?
You can use this treatment alongside niacinamide, applying the niacinamide first and letting it soak in before using this product. This helps keep your skin calm while smoothing texture, though acne-prone skin needs targeted ingredients like salicylic acid or benzoyl peroxide to directly clear breakouts.
How often should I use it?
Use this treatment in the evening once a week to start, since routines begin exfoliating steps slowly and use treatments at night for extra safety. If your skin feels comfortable and results look good, you may carefully use it more often. To truly tackle acne and breakouts for this skin, an acne product needs targeted ingredients that directly clear blemishes.
Can it clog pores, cause breakouts or purging for acne-prone skin?
This treatment is unlikely to clog pores, but its mild exfoliation may bring about some initial purging as cell turnover speeds up. Because it does not directly target active breakouts, acne-prone skin often needs a dedicated blemish-fighting ingredient like salicylic acid or benzoyl peroxide alongside hydrating and calming agents to stay clear and smooth.
Journal of Cosmetic Dermatology, 2020International Journal of Cosmetic Science, 2017
Is this exfoliant fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (benzyl alcohol). Cetearyl alcohol is a fatty alcohol, which soften the skin.
What the research says
