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 skin treatment for your normal skin, as retinal and Centella Asiatica promote cell turnover and calming effects, though these concentrations are mild for your pigmentation concerns.
- The formula provides general skincare benefits like hydration and soothing, which are supportive but not directly targeted at addressing pigmentation.
- The product is safe for your normal skin, with no risks of irritation due to the absence of harsh ingredients and the presence of soothing agents like Centella Asiatica and Niacinamide.

## What the research says

- Cosmetic formulations containing 5% Centella asiatica extract showed the best efficacy in improving skin moisture and decreasing transepidermal water loss, while also exhibiting antiinflammatory properties in 25 volunteers compared to baseline measurements.

([Molecules, 2023](https://pubmed.ncbi.nlm.nih.gov/37446936/))
- 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/))
- Treatment with a combination of niacinamide and hyaluronic acid improved skin aging signs and demonstrated a senomorphic effect by decreasing SASP and autocrine signaling genes in women. ([Scientific Reports, 2024](https://pubmed.ncbi.nlm.nih.gov/39009698/))
- Twice daily application of retinaldehyde 0.1% and 0.05% creams for 3 months improved skin texture and hydration and reduced transepidermal water loss in 40 female Korean volunteers, with only the 0.1% cream significantly improving the melanin index. ([Journal of Cosmetic Dermatology, 2018](https://pubmed.ncbi.nlm.nih.gov/29663701/))
- Topical retinaldehyde demonstrated significant antibacterial activity against gram-positive bacteria both in vitro and in vivo, leading to decreased bacterial counts without inducing resistance. ([Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12218231/))
- Topical 0.05% retinaldehyde applied over 1 year significantly increased epidermal thickness of the temple and cutaneous elasticity compared to an emollient control group in 40 aging skin patients. ([Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473959/))

([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.

## Questions and answers

### How well does MEDI THERAPY Retinal work for skin with dark spots?

MEDI THERAPY Retinal Skin Booster works moderately for skin with dark spots, as its ingredients help with cell turnover and calming, though the concentrations are mild for pigmentation concerns. A treatment of this type needs a blend of potent antioxidants, skin-repairing ingredients, and soothing agents to significantly benefit pigmentation without irritation.
Sources: [Indian Journal of Pharmaceutical Sciences, 2016](https://pubmed.ncbi.nlm.nih.gov/27168678/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/)

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

Retinal, Centella Asiatica, and Niacinamide make this serum a fit for skin with dark spots by helping promote cell turnover, calming the skin, and providing general soothing and hydration. However, a product for this skin needs higher concentrations of targeted pigmentation ingredients and effective antioxidants to deliver optimal results.
Sources: [Indian Journal of Pharmaceutical Sciences, 2016](https://pubmed.ncbi.nlm.nih.gov/27168678/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/)

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

Retinal helps fade dark spots and uneven pigmentation by encouraging faster skin turnover. It may also improve overall skin texture while maintaining a good safety profile for everyday use.
Sources: [Journal of Drugs in Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/39496127/), [Journal of Cosmetic Dermatology, 2018](https://pubmed.ncbi.nlm.nih.gov/30027612/)

### What does Centella Asiatica do for skin with dark spots?

Centella asiatica helps reduce dark spots by targeting the processes that cause excess pigment in the skin. Studies show that key compounds in this ingredient help calm the skin and manage melanin production.
Sources: [Molecular Medicine Reports, 2014](https://pubmed.ncbi.nlm.nih.gov/24756377/), [International Journal of Molecular Medicine, 2025](https://pubmed.ncbi.nlm.nih.gov/39513603/)

### 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, which keeps things simple and protects your skin during sun exposure. To properly target dark spots, a product of this type needs stronger concentrations of active ingredients like retinal and brightening agents.

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

You can use this treatment with vitamin C by applying your vitamin C in the morning and saving this treatment for the evening routine. This helps keep your skin calm while getting the most out of both ingredients.

### How often should I use this serum?

This treatment is used in the evening as part of your routine. Skincare for dark spots works best with higher concentrations of active ingredients and targeted brighteners like vitamin C or stronger retinoids.

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

This serum is unlikely to clog pores or cause breakouts on your skin, as it avoids harsh ingredients and includes soothing agents like Centella Asiatica and Niacinamide. It may cause mild cell turnover and light purging from the retinal, but this helps clear and smooth the skin over time.
