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

Brand: [De La Cruz](https://lovi.care/skincare/ca/brands/de-la-cruz)
Category: [Serums and treatments](https://lovi.care/skincare/ca/best/serums)

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.

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

## Why this fit

- Offers moderate exfoliation for redness and irritation due to the presence of sulfur, which helps with acne and inflammation, though it lacks sufficient humectant or emollient ingredients for optimal hydration for your normal skin.
- The absence of harsh ingredients ensures no risks of irritation for your sensitive skin.

## What the research says

- Azelaic acid was probably less effective than benzoyl peroxide in acne treatment response, while showing little or no difference compared to tretinoin, and adverse events were mild and transient across evaluated topical treatments. ([Journal of Evidence-based Medicine, 2020](https://pubmed.ncbi.nlm.nih.gov/33034949/))
- Topical application of precipitated sulphur 2-8% petrolatum achieved a 95% clinical and ectoparasitological cure rate in 40 ambulatory scabies patients without relevant adverse effects. ([Revista de Investigacion Clinica; Organo Del Hospital de Enfermedades de la Nutricion, 2004](https://pubmed.ncbi.nlm.nih.gov/15776866/))
- Topical 10% benzoyl peroxide and 2%-5% sulfur cream achieved "good" to "excellent" results with no undesirable side effects in 113 consecutive patients with acne. ([Canadian Medical Association Journal, 1966](https://pubmed.ncbi.nlm.nih.gov/4223133/))
- Binary systems of trans-resveratrol with polyethylene glycol or beta-cyclodextrin enhanced its antioxidant activity and in vivo skin anti-aging effects compared to trans-resveratrol alone in human keratinocytes and volunteers. ([Drug Development and Industrial Pharmacy, 2014](https://pubmed.ncbi.nlm.nih.gov/23862976/))
- Topical application of 30% salicylic acid in polyethylene glycol effectively cleared comedones and papules in 436 patients with acne while causing no stinging, burning, edema, bleeding, or crusting. ([Dermatologic Surgery, 2008](https://pubmed.ncbi.nlm.nih.gov/18363720/))
- Glycerol-containing zinc shake lotion and PEG gels produced hydration on nonmoisturized and moisturized skin in healthy volunteers, whereas zinc oil and Lotio Cordes had little impact on stratum corneum hydration. ([Skin Pharmacology and Applied Skin Physiology, 2001](https://pubmed.ncbi.nlm.nih.gov/11174089/))

## How to apply

- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .

## Questions and answers

### Why does Lovi advise caution with De La Cruz 10% Sulfur Ointment for sensitive skin?

Lovi advises caution because this treatment lacks enough moisture-adding or softening ingredients to keep normal skin hydrated while sulfur helps with acne and redness. A treatment of this type needs soothing antioxidants, hydrating components, and skin-repairing ingredients to properly care for sensitive skin.

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

Sulfur and polyethylene glycol make this ointment a poor fit because it lacks sufficient soft, smooth, moisturizing ingredients to keep this skin type comfortable. A treatment for this skin needs soothing antioxidants, hydrating components, and skin-repairing ingredients like niacinamide.

### What does Sulfur do for sensitive skin?

Topical sulfur helps manage various skin concerns with a low likelihood of irritation, though sensitive skin requires gentle formulations and careful monitoring. This type of skin needs soothing and protective ingredients like ceramides or niacinamide alongside treatments to prevent dryness and redness.
Sources: [Journal of Drugs in Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/15303787/)

### What does Polyethylene Glycol do for sensitive skin?

Polyethylene glycol is unlikely to cause irritation when used in properly formulated products for sensitive skin, though allergic reactions can occasionally occur in sensitive individuals. Products of this type need gentle, non-irritating ingredients and soothing agents to help calm sensitive skin without triggering redness.
Sources: [Acta Odontologica Scandinavica, 1997](https://pubmed.ncbi.nlm.nih.gov/9176662/), [The Journal of Allergy and Clinical Immunology. In Practice, 2019](https://pubmed.ncbi.nlm.nih.gov/30557713/)

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

This treatment goes in the evening routine for your sensitive skin. Since this product lacks the ingredients needed to keep normal skin soft and hydrated, this skin type needs extra soothing hydrators and moisturizers.

### Can I use this ointment with benzoyl peroxide, and in what order?

It is best to avoid using this sulfur ointment at the same time as benzoyl peroxide, as combining them may cause excessive dryness and irritation on your sensitive skin. If you do use both, alternate the days you apply them or use one in the morning and the other at night, always following up with a gentle moisturizer.

### How often should I use this ointment?

This ointment is a poor fit for sensitive skin, so you should use it cautiously and less frequently, such as once a week to test how your skin reacts. Sensitive skin needs gentle hydrating ingredients and soothing emollients to stay calm and comfortable while using treatments.

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

This ointment is unlikely to clog pores or cause breakouts for your sensitive skin, but because it is a poor match for you, a product of this type needs extra soothing and hydrating ingredients to keep dry skin comfortable.
