Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for dry or flaky skin due to the presence of sulfur, which helps shed dead skin cells, but may be too drying for your dry skin.
- While polyethylene glycol offers some humectant properties, it may not be sufficient to counteract the drying effect of sulfur for your dry skin.
How to apply
- Apply this serum PM, starting 3脳/week and working up to daily use as your skin adjusts.
- Place the serum after cleansing and toner, but right before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on slightly damp skin to help lock in extra moisture.
- Avoid the eye area and do a patch test before your first use.
Questions and answers
Why does Lovi advise caution with De La Cruz 10% Sulfur Ointment for dry skin?
Lovi advises caution because sulfur sheds dead skin cells through moderate exfoliation which may be too drying for your dry skin, and polyethylene glycol may not be sufficient to counteract that drying effect. A product for dry skin needs soothing and deeply hydrating ingredients like propolis, niacinamide, ceramides, vitamin C, bifida fermentation, or peptides to nourish and support skin health without irritation.
Which ingredients make this ointment a poor fit for dry skin?
Sulfur makes this ointment a poor fit because it sheds dead skin cells which may be too drying for dry skin, and polyethylene glycol may not be sufficient to counteract that drying effect. To fit dry skin properly, a treatment of this type needs soothing ingredients like propolis, niacinamide, ceramides, vitamin C, bifida fermentation, or peptides that provide significant hydration and support skin health without irritation.
What does Polyethylene Glycol do for dry skin?
Polyethylene Glycol helps boost skin hydration and improves the delivery of moisture into dry skin. However, it may sometimes cause allergic skin reactions or irritation, particularly on damaged or compromised skin.

Where does this ointment go in a skincare routine for dry skin?
This treatment goes in the evening routine after cleansing and before moisturizing, but it may be too drying for your dry skin. A product of this type needs gentle exfoliating ingredients paired with rich, deeply hydrating ingredients that keep the skin soft and comfortable.
Can I use this ointment with benzoyl peroxide, and in what order?
Using this ointment with benzoyl peroxide may excessively dry and irritate your skin, so it is best to avoid combining them in the same routine. If you choose to use both, apply them on alternate days or times to minimize irritation risks. A skincare routine for dry skin needs rich moisturizers with ceramides or hyaluronic acid and gentle hydrators to prevent moisture loss.
How often should I use this ointment?
This ointment may be too drying for your dry skin, so you should use it with caution and start just once a week. To care for dry skin properly, a product of this type needs rich moisturizing ingredients and gentle hydrators that can actively prevent moisture loss and flaking.
Can this ointment clog pores, cause breakouts or purging for dry skin?
This ointment is unlikely to clog pores or cause breakouts on dry skin, but its sulfur content may cause dryness or peeling. A product for this skin needs gentle moisturizers and hydrating ingredients to keep the skin soft and smooth.
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.
