Does DerMend work for bruising?
By Margaret Hale, Reunoa EditorialLast updated
The short answer
DerMend's ingredients have research behind them individually: arnica and vitamin K for bruise fading, ceramides for the barrier, and retinol and glycolic acid for thickening aged skin. We found no independent randomized trial of the DerMend product itself; the multi-ingredient approach is described in a review funded by its maker. Retinol and acids can irritate very thin skin at first.
DerMend Moisturizing Bruise Formula is one of the best-known US bruise creams for aging skin, often recommended in pharmacies. Here's a fair look at whether it works.
What's in it
According to its published ingredient list, DerMend contains arnica flower extract, phytonadione (vitamin K1), five ceramides, retinol, glycolic acid and niacinamide, among other ingredients [1]. The arnica concentration isn't stated publicly. The maker's directions are to apply twice daily to the whole affected area, not as a spot treatment [2].
Evidence by ingredient
| Ingredient | What the research shows |
|---|---|
| Arnica | 20% arnica beat placebo on laser bruises [4]; DerMend's % not stated |
| Vitamin K1 | Reduced bruise severity after laser treatment [5] |
| Ceramides | Barrier lipids improved barrier function in a trial [8] |
| Retinol | Increased procollagen in aged skin over 24 weeks [6] |
| Glycolic acid (AHA) | AHAs increased skin thickness ~25% in a pilot study [7] |
A dermatology review describes a topical regimen for actinic purpura combining these ingredient types; the review was funded by DerMend's maker [3]. We found no independent randomized trial of the finished DerMend product.
Who it may suit
- people with senile purpura and thin skin whose skin tolerates retinoids and acids
- people who want one product that targets both bruise fading and skin thickening
- those who prefer a rich cream texture
Who might prefer something else
- very thin, reactive skin that stings with retinol or glycolic acid
- people who already use a prescription retinoid (doubling up can irritate)
- those who want a known, stated arnica concentration
- people who prefer a light, fast-absorbing texture
How to try it well
- Patch-test on the inner forearm for a few days.
- Start once daily for the first week if your skin is sensitive.
- Use sunscreen in the morning (retinol and AHAs increase sun sensitivity).
- Give it 8–12 weeks to judge thickening effects.

What users commonly report
Without verified independent data we won't quote ratings. In public reviews of bruise creams with retinol and acids in general, the most common complaints are stinging, redness or peeling in the first weeks and a heavier texture; the most common praise is for fewer and faster-fading bruises over time. Your experience will depend largely on how your skin handles retinol.
Questions to ask yourself before buying
- Does my skin tolerate retinol or AHA products?
- Do I want a cream or a lighter serum?
- Am I already using a prescription retinoid?
- Am I on warfarin (ask about vitamin K)?
Frequently asked questions
Does DerMend really work on bruises?
Its ingredients have supporting evidence individually. We found no independent randomized trial of the product itself.
How long does DerMend take to work?
Bruise-fading ingredients may help within weeks; retinol and glycolic acid effects on skin thickness take months.
Can DerMend irritate thin skin?
Retinol and glycolic acid can sting, redden or peel very thin skin, especially at first. Patch-test and build up use.
Is DerMend safe with blood thinners?
It's a topical cosmetic used on unbroken skin, which doesn't affect how blood thinners work. On warfarin, ask about vitamin K-containing products.
