This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate brightening for your normal skin due to niacinamide and ascorbic acid, which help to even skin tone, but these ingredients are not targeted for your primary concerns of redness and irritation.
- While glycerin and hyaluronic acid provide hydration, they offer general skincare benefits that are mostly supportive rather than directly addressing your specific skin issues.
- The product is generally safe for your sensitive skin, with a low risk of irritation from ascorbic acid.

## What the research says

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- 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/))
- 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. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- Topical hyaluronic acid filler serum combined with Botulinum toxin type A lengthened the duration of the toxin's effect in reducing wrinkles compared to Botulinum toxin type A alone. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/))
- 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/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects. ([Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22206073/))
- Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- Topical 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, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 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, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- 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/))

## Questions and answers

### How well does Hydinity Vivid Brightening work for sensitive skin?

This serum is an average fit for your sensitive skin because its ingredients help even skin tone, but they do not directly target redness and irritation. While it is generally safe and unlikely to cause irritation, a product for this skin needs soothing and calming ingredients that specifically address redness while keeping the skin comfortable and balanced.

### Which ingredients make this serum a good fit for sensitive skin?

Glycerin, niacinamide, ascorbic acid, and hyaluronic acid make this serum work for your sensitive skin by offering moderate brightening and general hydration, though other products fit it better because they target redness and irritation. A treatment for this skin needs ingredients that calm redness and irritation, provide excellent skincare benefits, and pose no risk of irritation.

### What does Glycerin do for sensitive skin?

Glycerin helps keep sensitive skin soft and deeply hydrated while supporting the skin barrier. It is unlikely to cause irritation and may protect against dryness and roughness.
Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [Acta Dermato-venereologica, 1999](https://pubmed.ncbi.nlm.nih.gov/10598752/)

### What does Niacinamide do for sensitive skin?

Niacinamide helps calm sensitive skin by strengthening the skin barrier and reducing redness and irritation. It is very well tolerated and may improve overall comfort and resilience with regular use.
Sources: [Cutis, 2005](https://pubmed.ncbi.nlm.nih.gov/16209160/), [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/)

### Where does this serum go in a skincare routine for sensitive skin?

This treatment goes in your evening routine, applied after your cleanser and soothing toner and before your moisturizer. Putting it in the evening keeps things simple and provides extra safety around sun exposure.

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

You can use this serum with retinol, applying the treatment in the evening after a soothing toner and before your moisturizer. It is generally safe for your sensitive skin with a low risk of irritation, but sensitive skin needing this type of product works best with calming ingredients like centella asiatica or green tea to directly target redness.

### How often should I use this serum?

You can use this treatment in your evening routine, applying it once a day or a few times a week. To fit your sensitive skin better, a serum of this type needs calming ingredients that specifically soothe redness and irritation.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

### Can this serum clog pores, cause breakouts or purging for sensitive skin?

This serum is unlikely to cause major breakouts, though a small number of reviewers do report breakouts from it. It is generally safe for sensitive skin, but a product of this type needs calming ingredients and extra soothing agents to properly care for easily irritated skin.
