—
Extreme close-up of light skin in an active eczema flare, too close to tell which part of the body it is. Blotchy pink-red inflammation covers the whole frame with no clear edge, with small raised bumps, fine dry scale and a few fresh scratch marks.

Eczema

Trials of 1% creams support symptom relief and moisturizing care.
The front of one shin on pale skin. The surface is pink with fine white flaking and a few shallow cracks, and the skin around it is even in tone.

Dry Skin

Tested creams improved hydration and dryness.

Barrier Support

A controlled cream study supports improved barrier measurements.

Scars

Inflamed acne on light skin. The spots sit in a patch of pink, and the ring of redness around each one is easy to see. A few have a yellow-white head, and the skin between them is dry and flaking.

Acne

Strengths and forms

Concentrations

Cica usually means Centella asiatica extract, a mixture whose composition varies with extraction and standardization. There is no established percentage scale that makes different cica products equally potent.

Choosing a strength: Check whether the label names whole Centella extract, madecassoside, asiaticoside, or another purified compound.

Higher strengths: A higher extract percentage does not necessarily mean more of the compounds studied in clinical research.

Formula matters: A study of 0.1% madecassoside with 5% vitamin C cannot be used as a recommended percentage for whole cica extract.

A 1% colloidal oatmeal cream has clinical trial evidence for mild-to-moderate eczema. Different bath products and creams do not need the same percentage to meet their own labeling conditions.

1%

Studied eczema cream

A finished cream studied in children with mild-to-moderate atopic dermatitis. It does not establish that stronger creams work better.

Choosing a strength: Choose a labeled colloidal-oatmeal product and a texture that suits the area; bath powder and leave-on cream are different formats.

Higher strengths: A higher oat percentage is not a proven upgrade. Stop and reassess if the product causes an itchy rash or other signs of allergy.

Formula matters: Colloidal oatmeal is a processed ingredient, not interchangeable with kitchen oats or an arbitrary oat extract.

Safety and sensitive skin

Common reactions

Can cause a contact rash; avoid assuming botanical products are allergy-free.

Avoid if you have reacted to oats or the product; stop for a new rash.

When to stop

Stop for persistent burning, swelling, blistering or a new rash. Seek urgent care for breathing difficulty or a severe allergic reaction.

Important limits

Do not use a cosmetic product as a substitute for diagnosis of an unexplained, changing or persistent skin problem.

Pregnancy

Applied to the skin, very little is expected to be absorbed, but ask the doctor managing your pregnancy. Mention it separately if you also take gotu kola by mouth.

Colloidal oatmeal products are generally considered acceptable in pregnancy.

Common questions

Cica:What should I choose cica for?

Consider for a gentle moisturizer; check the complete formula and your tolerance.

Cica:How strong is the evidence?

A 20-person study tested madecassoside together with vitamin C for six months. It cannot isolate Centella extract or establish treatment of acne, eczema or scars.

Colloidal Oatmeal:What should I choose colloidal oatmeal for?

Choose for dry, itchy or eczema-prone skin in a fragrance-free formula.

Colloidal Oatmeal:How strong is the evidence?

Trials support specific 1% oatmeal creams, including an active-comparator pediatric trial. They do not establish treatment of the cause of hives, psoriasis or acne.
