Strengths and forms

Concentrations

Allantoin’s U.S. skin-protectant range is 0.5–2%. This is a labeled protective use, not a concentration proven to erase scars.

0.5–2%

U.S. skin-protectant range

Used in qualifying protective products for skin comfort. Cosmetic formulas may include allantoin without stating its percentage.

Choosing a strength: Choose a finished cream or ointment suited to the area. For scars, assess evidence for the whole treatment rather than allantoin alone.

Higher strengths: More allantoin is not established as a better scar treatment or a substitute for care of a nonhealing wound.

Formula matters: Allantoin is often one ingredient in a moisturizing blend. Benefits of a combination product cannot be assigned to allantoin alone.

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.

Safety and sensitive skin

Common reactions

Usually comfortable; discontinue for a rash or persistent stinging.

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

When to stop

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

Sensitive or inflamed skin

Choose a simple formula and test a small area first. Individual tolerance matters more than an ingredient’s reputation for being gentle.

Important limits

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

Pregnancy

Very little is absorbed through the skin and it has a long record of use, but this is a question for the doctor managing your pregnancy, not for a label.

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.

How it works

In the skin

On the skin. The finished product delivers allantoin in a particular vehicle.

Entering skin. Below the 500 Da guideline; delivery still depends on the formula, solubility, stability and skin condition. Size does not prove effectiveness or penetration depth.

Conversion. No activation step is established as necessary for its intended topical role.

Skin response. Contributes protective and conditioning effects in topical formulas; proposed repair pathways are mainly experimental.

Additional effects. Proposed pathways do not establish a measured depth of delivery or clinical benefit beyond the studies cited.

On the skin. The finished product delivers cica in a particular vehicle.

Entering skin. No single molecular mass. The 500 Da guideline cannot be applied to this whole ingredient family or mixture.

Conversion. No activation step is established as necessary for its intended topical role.

Skin response. Contains plant compounds studied for inflammatory and repair signalling; extracts are not chemically identical.

Common questions

Allantoin:What should I choose allantoin for?

Consider in a gentle skin-protectant formula, without expecting scar removal.

Allantoin:How strong is the evidence?

Skin-protectant use is recognized in the FDA monograph. The cited wound-healing experiment was in rats and cannot establish faster human wound healing or acne treatment.

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.
