This fit is calculated for the concerns frequently associated with dark spots: hyperpigmentation, sun spots, and uneven skin tone. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

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

## Why this fit

- Offers moderate antioxidant protection and brightening for your normal skin due to the presence of ascorbic acid, which provides general skincare benefits but is not in a concentration optimized for treating your specific pigmentation concerns.
- The formula is generally suitable for normal skin, and while it offers hydration and cleansing, its primary function is not directly targeted at addressing hyperpigmentation.
- The product is safe for your skin, as it contains no harsh ingredients and carries no risk of irritation.

## What the research says

- A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/))
- Vitamin C mesotherapy produced a significant and earlier reduction in gingival pigmentation and higher patient satisfaction compared to topical gel in twenty healthy non-smokers with hyperpigmented gingiva, with both methods reducing the mean area fraction of melanin-forming cells at 6 months without causing pain. ([Clinical Oral Investigations, 2021](https://pubmed.ncbi.nlm.nih.gov/33966113/))
- Topical application of 5% vitamin C cream significantly improved global clinical scores, increased skin microrelief density, and induced elastic tissue repair in photoaged skin compared to excipient control in healthy female volunteers. ([Experimental Dermatology, 2003](https://pubmed.ncbi.nlm.nih.gov/12823436/))
- Ascorbic acid 2-glucoside gel significantly reduced gingival melanin pigmentation after 4 weeks compared to placebo in 73 subjects with symmetric pigmentation. ([Journal of Periodontology, 2009](https://pubmed.ncbi.nlm.nih.gov/19186973/))
- Topical application of VC-IP cream twice daily for 8 weeks reduces periorbital wrinkles in female subjects compared to a placebo cream. ([Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/34910367/))
- Treatment with a combination of propylene glycol, ethanol, water, and shampoo was found effective, easy to use, and cosmetically attractive with no observed side effects in patients with dandruff. ([Cutis, 1988](https://pubmed.ncbi.nlm.nih.gov/2970946/))
- A moisturizer containing glycerol and propylene glycol reduced transepidermal water loss, decreased epidermal thickness, increased stratum corneum thickness, and reduced dermal inflammatory infiltrate compared to untreated disrupted skin in six healthy beagle dogs. ([Veterinary Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32628309/))

## Questions and answers

### How well does Obagi Professional-C Serum 10% work for skin with dark spots?

Obagi Professional-C Serum 10% works moderately well for skin with dark spots, as it helps brighten and protect normal skin with ascorbic acid, though its concentration is not fully optimized for specific pigmentation concerns. It is safe and unlikely to cause irritation, but treatments that fit this skin better typically need potent antioxidants, soothing ingredients, hydration, and targeted brighteners like niacinamide and propolis.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

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

Ascorbic acid makes this serum a fit for skin with dark spots by offering moderate brightening and antioxidant protection. For a better fit, dark spots need a formula with potent antioxidants, soothing ingredients like niacinamide and propolis, and hydration that target pigmentation more effectively.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### What does Vitamin C do for skin with dark spots?

Vitamin C helps fade dark spots and brightens uneven skin. It works by slowing down pigment production and boosting overall skin clarity.
Sources: [Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029672/)

### What does Propylene Glycol do for skin with dark spots?

Propylene glycol is unlikely to fade dark spots on its own, but it helps other active ingredients soak into your skin more effectively. A product of this type needs brightening ingredients like vitamin C or niacinamide to specifically target dark spots.
Sources: [The Journal of Physical Chemistry. B, 2024](https://pubmed.ncbi.nlm.nih.gov/38622775/)

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

This treatment goes in the evening routine after cleansing and before moisturizing, though products targeting dark spots work best when they feature higher concentrations of brightening ingredients optimized for pigmentation.

### Can I use this serum with retinol, and in what order?

You can use this serum with retinol by applying them at different times of day, such as vitamin C in the morning and retinol at night, to help prevent irritation. This product is safe for your skin with no harsh ingredients, but dark spots need ingredients specifically targeted at fading pigmentation and optimized for stronger brightening.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### How often should I use this serum?

This treatment is used in the evening for simplicity and extra safety around sun exposure, though some treatments can also be used in the morning or twice a day. A product of this type needs targeted brightening ingredients and optimal concentrations specifically designed to treat your dark spots.

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

This serum is unlikely to clog pores or cause breakouts for skin with dark spots, as it contains no harsh ingredients and carries a very low risk of irritation. A product of this type needs targeted brightening ingredients and an optimized concentration to effectively treat dark spots.
