Lovi Assistant explains
- Offers excellent exfoliation for your combination skin, as mandelic acid and lactic acid work to smooth texture and reduce blemishes while niacinamide helps regulate oil production.
- The presence of Saccharomyces Zinc Ferment and amino acids further supports skin health and hydration, complementing the keratolytic action.
- The formula is safe for your skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Use this exfoliant PM once a week to start, and gradually increase if your combination skin tolerates it well. Always apply SPF the next morning to protect your clear skin.
- Apply the exfoliant after cleansing and toning, but right before your moisturizer step. This ensures the treatment targets blemishes effectively.
- Gently press 2-3 drops of the exfoliant into your skin without rubbing. Let it absorb for a minute before moving to the next step.
- Apply the exfoliant on clean, dry skin to help control breakouts safely. Since your skin is not sensitive, this dry application method ensures good product absorption.
- Avoid the sensitive eye area and do a patch test before your first use. Do not mix this exfoliant with other strong acids in the same routine.

Questions and answers
What makes Vivant 8% Mandelic Acid Serum a great fit for acne-prone skin?
Which ingredients make this serum a good fit for acne-prone skin?
Mandelic acid and lactic acid make this serum a great fit for your acne-prone skin because they smooth texture and reduce blemishes, while niacinamide helps regulate oil. These ingredients work together safely to clear pores without causing irritation, leaving your skin smooth and calm.
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.
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 serum go in a skincare routine for acne-prone skin?
This serum goes in the evening routine after cleansing and before moisturizing, starting once a week and gradually increasing as tolerated. Putting treatments in the evening provides simplicity and extra safety around sun exposure.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol, but it is best to apply them on alternate nights or separate them into your morning and evening routines to avoid irritation. Using both strong treatments at the same time may dry out your skin, so alternate them to keep your face calm and smooth.
How often should I use this serum?
Start by using this serum once a week in the evening, and if your skin feels comfortable and you see good results, you can carefully use it more often. The formula smooths texture, helps reduce blemishes, and regulates oil while supporting overall skin health.
Can this serum clog pores, cause breakouts or purging for acne-prone skin?
This serum is a great fit because mandelic acid and lactic acid smooth texture and reduce blemishes while niacinamide helps control oil, though you may notice a little initial dryness. It is unlikely to cause breakouts or clog pores, and a product for this skin needs gentle exfoliating acids and oil-regulating ingredients like these.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
What the research says
Treatment with 45% mandelic acid peel showed nearly equal overall efficacy as 30% salicylic acid peel in patients with mild-to-moderate facial acne vulgaris, but with fewer adverse effects.
Journal of Cosmetic Dermatology, 2020Commonly used chemical peels showed no significant differences in effectiveness for acne vulgaris in most comparisons, though combined salicylic and mandelic acid peeling was superior to glycolic acid and glycolic acid was superior to placebo, based on twelve randomized controlled trials.
BMJ Open, 2018Chemical peels using 35% glycolic acid, 20% salicylic-10% mandelic acid, and phytic acid reduce acne scores by 70.55%, 74.14%, and 69.7% respectively, and significantly decline the postacne hyperpigmentation index in Asian patients with mild to moderate acne.
Journal of Cutaneous and Aesthetic Surgery, 2019Treatment with 30% lactic acid peel showed a significantly greater reduction in pigmentation and higher patient satisfaction compared to 30% mandelic acid peel in patients with periorbital melanosis.

Journal of Cosmetic Dermatology, 2021Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women.
The Journal of Investigative Dermatology, 2008Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging.
Dermatologic Surgery, 2005Application of a cream containing lactic acid 12% and pramoxine HCl 1% significantly improved skin dryness, hydration, and itch compared with a nontreated control in 24 women with a history of dry itchy skin.
Cutis, 2004Topical 12% ammonium lactate produced a significant sparing of epidermal and dermal atrophy induced by clobetasol propionate in human volunteers, without influencing the corticosteroid's bioavailability or antiinflammatory properties.
Journal of the American Academy of Dermatology, 1992A lactic acid/ceramide lotion significantly improved skin moisturization and desquamation compared to no treatment in women with dry, rough skin on the anterior shins.
The Journal of Clinical and Aesthetic Dermatology, 2020Specially neutralized 12% lactate lotion provided significantly greater reductions in xerosis severity scores compared with a nonlactated emollient lotion and a 5% lactic acid lotion during the post-treatment regression period in sixty patients with moderate to severe xerosis.
Archives of Dermatology, 1983Long-pulsed alexandrite laser achieved a significantly greater mean percent reduction in pigmentation area compared to topical tretinoin-ammonium lactate (25.7% versus 18.3%) in 15 patients with bilateral axillary acanthosis nigricans over 14 weeks.
Caspian Journal of Internal Medicine, 2016Topical application of 5% aqueous lactate lotion twice a day for 1 year achieved a 90-100% reduction in inflammatory lesions in 40.9% of patients and in non-inflammatory lesions in 22.7% of patients, with most patients showing significant reduction in lesion counts.
