Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate brightening for your combination skin as diglucosyl gallic acid and niacinamide help even skin tone and provide antioxidant activity. Glycerin and shea butter offer hydration and soothing benefits for your acne, blemishes, and breakouts.
- The formula is safe for your combination skin with no risks of irritation due to the absence of harsh ingredients.
- While it provides general skincare benefits and moderate brightening, it lacks sufficient ingredients for optimal oil control on your oily areas.
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 Gundry MD Polyphenol Dark Spot Diminisher work for acne-prone skin?
Gundry MD Polyphenol Dark Spot Diminisher works moderately well for acne-prone skin, offering helpful brightening and soothing hydration without causing irritation. However, it lacks sufficient oil-control ingredients for oily areas. Acne-prone skin needs products containing ingredients like zinc PCA and propolis to balance oil and manage breakouts effectively.
The British Journal of Dermatology, 2002International Journal of Cosmetic Science, 2022
Which ingredients make this cream a good fit for acne-prone skin?
Diglucosyl gallic acid and niacinamide help even skin tone, while glycerin and shea butter offer hydration and soothing benefits for blemishes. However, acne-prone skin needs additional ingredients like propolis or zinc PCA to provide optimal oil control and balance.
The British Journal of Dermatology, 2002International Journal of Cosmetic Science, 2022
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.
What does Diglucosyl Gallic Acid do for acne-prone skin?
Diglucosyl gallic acid helps brighten skin and fade dark spots, but acne-prone skin also needs ingredients that clear pores and calm redness.
International Journal of Cosmetic Science, 2022Journal of Cosmetic Dermatology, 2020
Where does it go in a skincare routine for acne-prone skin?
This treatment goes in your evening routine after cleansing and before moisturizing. A product for this skin needs extra oil-controlling ingredients to manage oily areas.
Can I use this cream with retinol, and in what order?
You can use this treatment alongside retinol by applying the retinol first at night and following it with this cream to keep your skin calm and hydrated. Because this product lacks oil control, acne-prone skin needs a product with ingredients that balance oil production and clear pores.
How often should I use it?
You can use this treatment in the evening as part of your routine. It is safe for your skin with no risks of irritation, though acne-prone skin needs extra ingredients for oil control.
Can this cream clog pores, cause breakouts or purging for acne-prone skin?
This treatment is unlikely to cause irritation on your acne-prone skin since the formula leaves out harsh ingredients. However, it may not work as well as other products for this skin type because it lacks enough oil-controlling ingredients to properly manage oily areas.
Is it fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (parfum).
