The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Saudi Arabia.

Brand: [Cos De BAHA](https://lovi.care/skincare/sa/brands/cos-de-baha)
Category: [Serums and treatments](https://lovi.care/skincare/sa/best/serums)

This fit is calculated for the concerns frequently associated with dry sensitive skin: flakiness, tightness, redness, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

A poor match for dry sensitive skin; the serums alongside fit it better.

## Why this fit

- Offers moderate exfoliation for your dry or flaky skin due to salicylic acid and lactic acid, which can cause dryness and irritation, potentially worsening your dry or flaky skin.
- Arbutin and hydroquinone provide moderate skin brightening to even skin tone, but the combination of exfoliating acids and humectant sodium hyaluronate may not fully counteract the drying effects for your dry skin.

## What the research says

- TFC-1067 and 2% hydroquinone both significantly lightened facial dyschromia after 8 and 12 weeks in 48 healthy female subjects, but only hydroquinone also lightened normal skin. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/33098161/))
- A non-hydroquinone topical formulation (SKNB19) improved hyperpigmentation by 28.5% in patient self-assessment and 27% in independent reviewer assessment compared with 4% hydroquinone in 18 adult subjects, while showing significantly less irritation and better tolerability. ([Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/33022197/))
- Encapsulation of alpha arbutin in an optimized ethosomal gel significantly improved skin melanin reduction, moisture content, and elasticity in human volunteers compared to conventional formulations. ([Heliyon, 2023](https://pubmed.ncbi.nlm.nih.gov/37681127/))
- Combining a home-based radiofrequency device and arbutin cream reduced mMASI scores by 25.6% and melanin index by 22.8% at 8 weeks compared to baseline in 38 participants. ([Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/39918262/))
- 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/))
- A topical formulation containing kojic acid, emblica extract, and glycolic acid demonstrated efficacy parity compared with hydroquinone 4% in multiethnic participants with mild to moderate facial dyschromia. ([Cutis, 2010](https://pubmed.ncbi.nlm.nih.gov/21049734/))
- A nanoemulsion containing 1 mg/mL kojic dipalmitate and 5% rosehip oil demonstrated high incorporation efficiency, suitable physicochemical stability, antioxidant and depigmenting efficacy close to 1 mM ascorbic acid, and no cytotoxicity at concentrations from 0.06% to 1% in vitro. ([Pharmaceutics, 2023](https://pubmed.ncbi.nlm.nih.gov/36839792/))
- Topical application of iron chelators kojic acid and deferiprone significantly accelerated wound healing in rats compared to control groups, with deferiprone showing superior efficacy due to higher antioxidant and iron chelation abilities. ([International Wound Journal, 2013](https://pubmed.ncbi.nlm.nih.gov/22621771/))
- Cryotherapy with liquid nitrogen achieved a higher cure rate (39%) than salicylic acid (24%) and a wait-and-see approach (16%) for cutaneous warts at 13 weeks in primary care patients. ([CMAJ, 2010](https://pubmed.ncbi.nlm.nih.gov/20837684/))
- A moisturizer containing licochalcone A, 1,2-decanediol, L-carnitine, and salicylic acid significantly reduced noninflammatory, inflammatory, and total acne lesion counts compared to a vehicle control in Thai patients during a 12-week maintenance phase. ([BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/))

## What reviewers say

This serum is highly effective for hyperpigmentation and dark spots, with many users reporting visible improvements in skin tone and clarity.

## How to apply

- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

## Questions and answers

### Why does Lovi advise against Cos De BAHA Hydroquinone Brightening Serum for dry sensitive skin?

Lovi advises against this product because its exfoliating acids can cause dryness and irritation, which may worsen your dry and sensitive skin. Treatments that fit this skin well need gentle hydrating ingredients, ceramides, and vitamins to provide moisture and protect the skin barrier without any risk of irritation.

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

Salicylic acid and lactic acid make this serum a poor fit because they exfoliate and can cause dryness and irritation on dry skin. Products for this skin need gentle hydrating and nourishing ingredients, such as ceramides and multiple forms of vitamin C, that provide moisture retention and skin barrier support without any risk of irritation.

### What does Hydroquinone do for dry sensitive skin?

Hydroquinone is unlikely to be a good fit for dry sensitive skin because it may cause irritation and redness in delicate skin types. A product of this type needs soothing and hydrating ingredients like polyhydroxy acids to keep sensitive skin calm and smooth.
Sources: [Experimental Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36463492/), [Cutis, 2004](https://pubmed.ncbi.nlm.nih.gov/15002656/)

### What does Arbutin do for dry sensitive skin?

Arbutin helps fade dark spots and even out skin tone. For dry sensitive skin, it is generally well tolerated and unlikely to cause irritation, though a product of this type needs added hydrating ingredients and gentle soothing agents to keep dry skin comfortable.
Sources: [Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/33022197/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34356362/)

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

This serum is a poor fit for dry sensitive skin because its exfoliating acids and brightening ingredients can cause dryness and irritation. If you still choose to use it, treatments of this type go in the evening routine, and this skin type needs gentle hydrating ingredients and soothing moisturizers to prevent irritation.

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

You should avoid using this treatment alongside retinol on dry sensitive skin, because the exfoliating acids and hydroquinone inside may cause excessive dryness and irritation. If you choose to use strong active treatments like this, your skin needs rich hydrating ingredients and gentle soothing agents to protect its moisture barrier.

### How often should I use this serum?

This serum is a poor match for your dry sensitive skin because its exfoliating acids can cause dryness and irritation. A product of this type needs gentle exfoliating ingredients alongside rich moisturizers and hydrating agents to keep dry skin calm and smooth.

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

This serum is unlikely to clog pores or cause breakouts on dry sensitive skin, but its exfoliating acids may cause dryness and irritation. A product for this skin needs gentle hydrating ingredients and soothing agents to keep the skin soft and calm without irritation.

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

Yes, it has no fragrance and no drying alcohol.
