  • Emollient Therapy — Daily unperfumed moisturisers are first-line for toddler eczema; lotion, cream, gel and ointment work equally; they treat, not prevent.
  • Petrolatum — Most occlusive emollient base; penetrates stratum corneum, speeds barrier repair; rarely allergenic; no benefit for infant prevention.
  • Mineral Oil — Refined petroleum oil (liquid paraffin) in licensed emollients; beaten by virgin coconut oil in one child RCT; fire risk on fabric.
  • Glycerol — Humectant in many standard emollients; RCTs show it improves skin hydration and modestly helps eczema, with less stinging than urea.
  • Urea Creams — Urea humectant emollients (2–10% for eczema): low-quality evidence of benefit, more side effects than control; often sting raw toddler skin.
  • Ceramides — Barrier lipids depleted in eczema; ceramide creams sting less than urea, but paediatric RCTs show them no better than paraffin emollients.
  • Linoleic Acid — Omega-6 fatty acid; plant oils with a high linoleic:oleic ratio (e.g. sunflower) are thought to support, not damage, the skin barrier.
  • Oleic Acid — Omega-9 fatty acid dominant in olive oil; described as irritating and detrimental to the skin barrier (Vaughn 2018; Danby 2013).
  • Aqueous Cream — SLS-containing cream no longer advised as a leave-on emollient for eczema; stung in 56% of child exposures in one clinic audit.
  • Sodium Lauryl Sulfate — Detergent in aqueous cream, toothpaste, shampoo, bubble bath; thinned the skin barrier 12% in 4 weeks (Tsang & Guy 2010); stings eczema.
  • Emollient Bath Additives — Oils/emulsions poured into bath water; BATHE RCT found no added benefit in children 1–11, so NHS England and NICE no longer advise them.
  • BATHE Trial — UK RCT (Santer, BMJ 2018) of 483 children aged 1–11: emollient bath additives added no benefit to standard eczema care.
  • BEE Trial — UK RCT (Ridd 2022) of 550 children 6 mo–12 y: lotions, creams, gels and ointments equally effective; ointments sting least.
  • BEEP Trial — UK RCT of 1,394 high-risk newborns: daily emollient in year 1 did not prevent eczema (age 2 or 5) and raised skin infections.
  • PreventADALL Trial — Norway/Sweden RCT (2,397 babies): early emollients did not prevent eczema or food allergy; early allergenic foods cut food allergy at 3.
  • Emollient Fire Risk — Dried emollient residue on fabric makes it ignite fast and burn hot; MHRA says this applies to paraffin-free products too.
  • Bathing Frequency — Daily vs twice-weekly bathing in childhood eczema; small RCTs disagree, but soak-then-moisturise bathing is safe and may help acute flares.
  • Soak and Seal — Lukewarm soak, pat damp, then medicine on patches and emollient everywhere within ~3 min; twice-daily soaks cut SCORAD 21 points (2020 RCT).
  • Soap Substitutes — Washing with a leave-on emollient or soap-free wash instead of alkaline soap; clinical consensus, untested in trials, cheap and safe.
  • Syndet Cleansers — Synthetic-detergent cleansers (pH 5.5–7) that strip less lipid and shift skin pH less than soap; liquids more reliably acidic than bars.
  • Wet Wrap Therapy — Damp cotton layer plus dry layer over emollient or steroid for severe flares; helps in practice but low-quality evidence it beats TCS alone.
  • Barrier Creams — Protective ointments (petrolatum, zinc oxide, dimeticone) applied thinly to nappy and drool areas to shield skin from urine, faeces, saliva.
  • Colloidal Oatmeal — FDA OTC skin protectant for eczema itch; paediatric RCT shows parity with barrier cream, but oat proteins can sensitise infants with AD.
  • Sunflower Seed Oil — Linoleic-rich oil that spared the adult barrier (Danby 2013) and cut preterm infections, but delayed neonatal lipid lamellae (Cooke 2016).
