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.

A great choice for skin with dark spots; a few moisturizers fit it even better.

## Why this fit

- Offers high suitability for your normal skin, as niacinamide and glycerin provide excellent moisturizing and seboregulation, while niacinamide and acetyl glucosamine target hyperpigmentation and improve skin tone.
- The formula is highly compatible with normal skin due to niacinamide's antioxidant activity and glycerin's humectant action, further enhancing skin tone.
- The product is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

([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/))

- Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups. ([Military Medicine, 2024](https://pubmed.ncbi.nlm.nih.gov/38771104/))
- Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms.

## Questions and answers

### What makes Neutrogena Hydro Boost+ Niacinamide Serum a great fit for skin with dark spots?

Neutrogena Hydro Boost+ Niacinamide Serum is a great fit for skin with dark spots because niacinamide and acetyl glucosamine help fade uneven skin tone and dark patches, while glycerin and sodium hyaluronate keep skin feeling soft and moisturized. The formula is very safe and unlikely to cause irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

Niacinamide and acetyl glucosamine make this serum a great fit because they target dark spots and help improve uneven skin tone. Niacinamide significantly decreases hyperpigmentation, and combining it with acetyl glucosamine gives an even greater effect on fading pigmented spots.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

Niacinamide helps fade dark spots and uneven pigmentation by slowing down the transfer of pigment in the skin. It is generally well tolerated and may improve overall skin brightness with consistent use.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

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

Hyaluronic acid is unlikely to directly fade dark spots, but it helps keep dry and uneven skin plump and deeply hydrated. To effectively target dark spots, this type of skin needs brightening ingredients like vitamin C or niacinamide alongside your hydrator.

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

This serum goes in your evening routine, applied before your moisturizer for simplicity and extra safety around sun exposure. Niacinamide and acetyl glucosamine target dark spots to help improve your skin tone.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

Yes, you can use this serum with retinol by applying the serum first to keep your skin hydrated and help fade dark spots while your skin gets used to retinol. This approach is unlikely to cause irritation because the formula is gentle and free of harsh ingredients.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

### How often should I use this serum?

You can use this serum in your evening routine, applying it once a day for simplicity and safety around sun exposure. Some people may also use it in the morning or twice a day.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

### 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, and harsh ingredients are absent so it is safe for daily use. A few reviewers mention breakouts, but the gentle formula generally fits this skin well.

### Can I use this serum around the eyes or on my body?

You can use this serum around the eyes because the thin skin there tolerates its gentle ingredients well, but it is best reserved for smaller facial areas rather than the whole body. The formula is unlikely to cause irritation while helping to smooth and balance the skin.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/)

### Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
