Works for skin with dark spots; other serums fit it better.

## Why this fit

- Offers moderate exfoliation for pigmentation and texture refinement suitable for your normal skin, as mandelic acid and retinol promote skin renewal and cell turnover.
- The formula provides basic hydration and nourishment, though additional humectants could enhance overall comfort for normal skin.
- The product is generally safe for your skin, with minimal risks of irritation from mandelic acid and retinol.

## What the research says

- Topical bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging. ([The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/))
- Topical 0.4% retinol significantly increased epidermal thickness, dermal vascularity, and extracellular matrix production by stimulating keratinocyte proliferation, endothelial cell proliferation, and fibroblast activation in naturally aged human skin compared to vehicle. ([International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/))
- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.

- Chemical 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, 2019](https://pubmed.ncbi.nlm.nih.gov/31619887/))
- Commonly 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, 2018](https://pubmed.ncbi.nlm.nih.gov/29705755/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))

- Topical stabilized retinol treatment induced HAS gene expression and increased hyaluronic acid production in human skin in vitro, ex vivo, and in vivo compared to vehicle. ([Archives of Dermatological Research, 2017](https://pubmed.ncbi.nlm.nih.gov/28247017/))
- Topical application of all-trans-retinol induced epidermal thickening and increased retinoid binding protein expression similar to all-trans-retinoic acid in normal human skin, but without causing significant erythema or measurable retinoic acid levels.

- Treatment with 14% ferulic acid and 12% l-ascorbic acid significantly reduced pigmentation and erythema while improving hydration and elasticity in 20 women with photoaged skin, with neither acid proving definitively more effective overall though ascorbic acid showed slightly greater skin lightening.

- Combining fractional microneedle radiofrequency with a topical antioxidant serum significantly reduced wrinkle severity by 29.9% versus 18.0%, increased elasticity by 12.9% versus 2.3%, and improved aesthetic outcomes in 31 participants compared to radiofrequency and placebo. ([The Journal of Dermatological Treatment, 2025](https://pubmed.ncbi.nlm.nih.gov/40464749/))
- Pretreatment with a topical antioxidant mixture of vitamin C, ferulic acid, and phloretin attenuated ultraviolet-induced sunburn cell formation, thymine dimer formation, matrix metalloproteinase-9 expression, p53 protein expression, and the suppression of CD1a-expressing Langerhans cells in human skin compared to vehicle control.

## Questions and answers

### How well does The INKEY List Mandelic Acid work for skin with dark spots?

This treatment works for skin with dark spots by using mandelic acid and retinol to help renew the skin and fade dark spots, though other products fit this skin better. A product for this skin needs strong antioxidants and soothing ingredients to help clear dark spots without causing irritation, along with extra hydrating ingredients.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### Which ingredients make this exfoliant a good fit for skin with dark spots?

Mandelic acid and retinol make this treatment a good fit because they help fade dark spots by promoting skin renewal and cell turnover. To work best for dark spots, a treatment for this skin type needs potent antioxidants, soothing ingredients like niacinamide and propolis, and extra hydrating components to keep skin comfortable.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### What does Mandelic Acid do for skin with dark spots?

Mandelic acid helps fade dark spots and uneven skin tone while being generally gentle on the skin. It works by gently exfoliating the outer layer to reveal fresher, more even skin underneath. To properly treat dark spots, a product of this type needs additional brightening ingredients and soothing agents to calm the skin and improve pigment reduction.
Sources: [Journal of Cosmetic Dermatology, 2016](https://pubmed.ncbi.nlm.nih.gov/27028014/)

### What does Glycerin do for skin with dark spots?

Glycerin helps keep dry skin hydrated and supports a healthy skin barrier, which makes skin feel soft and smooth. While it does not directly fade dark spots on its own, it is often added to spot-fading products to keep the skin comfortable while other ingredients work.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Acta Dermato-venereologica, 2017](https://pubmed.ncbi.nlm.nih.gov/27349297/)

### Where does it go in a skincare routine for skin with dark spots?

This treatment goes in the evening routine after cleansing and before moisturizing, starting once a week and slowly using it more often if your skin tolerates it well. Skincare for dark spots of this type also needs extra hydrating ingredients to keep normal skin fully comfortable.

### Can I use this exfoliant with niacinamide, and in what order?

You can use this treatment with niacinamide by applying niacinamide first and letting it absorb before putting on this formula. This routine helps brighten dark spots and refine texture while keeping skin comfortable, though this skin type needs extra hydrating ingredients to prevent dryness.

### How often should I use it?

Start by using this treatment once a week in the evening, and if your skin feels comfortable, you can carefully use it more often. This product needs extra hydrating ingredients to boost comfort and better address dark spots on normal skin.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

### Can this exfoliant clog pores, cause breakouts or purging for skin with dark spots?

This treatment is unlikely to clog pores, but the mandelic acid and retinol in it help speed up cell turnover, which may cause some initial purging on skin with dark spots. A product of this type needs reliable exfoliating acids and soothing hydrators to help clear dark spots while keeping normal skin comfortable.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### Is it 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.
