Efficacy of anti-sebum moisturizing cream containing 2% l-carnitine and 5% epigallocatechin gallate in seborrhea: A randomized clinical trial
- Kind of evidence
- Human trial 2023 · 90 people · subjects with seborrhea · PMID 37194909
- Measured outcome
- Skin effect
- Year
- 2023
- Who was studied
- 90 subjects with seborrhea
- Sample size
- 90
- Measured outcome
- In 90 people with seborrhea, moisturisers containing 2% L-carnitine, 5% epigallocatechin gallate, or both produced statistically significant reductions in sebum level from baseline over 4 weeks, with the EGCG and combination groups showing greater anti-sebum effects than L-carnitine alone (p = 0.009).
- Certainty
- Moderate
- Who was measured
- People with seborrhea applying an anti-sebum moisturising cream for 4 weeks.
- Study limits
- All three arms contained active ingredients; sebum was measured alongside hydration and TEWL improvements.

- Skin effectEffects of a grapeseed oil (Vitis vinifera L.) loaded dermocosmetic nanoemulgel on biophysical parameters of facial skin: A split-face, blinded, placebo-controlled study
In a split-face, blinded, placebo-controlled study of 15 volunteers, a grapeseed-oil nanoemulgel applied for 12 weeks significantly reduced facial sebum production and fine and large pores while significantly increasing skin moisture content and elasticity versus placebo (all p<0.05).

In a 12-week single-blind, base-controlled study in healthy men, a cream containing 3% Cannabis seed extract significantly reduced cheek sebum and erythema compared with the extract-free base (p<0.05).

- Skin effectThe effect of 2% niacinamide on facial sebum production
In a double-blind, placebo-controlled trial of 100 Japanese subjects, a 2% niacinamide moisturiser significantly lowered sebum excretion rate after 2 and 4 weeks; in a separate 30-person Caucasian split-face study it significantly reduced casual sebum level after 6 weeks.
Human trial · 2006 · 100 people · Japanese subjects plus 30 Caucasian subjects · Adults with facial sebum concerns applying a 2% niacinamide moisturiser for 2 to 6 weeks; measured with sebumeter-based sebum excretion rate and casual sebum level. · The effect differs by measured endpoint and population.
