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.

Aloe percentages usually describe an extract, gel, or juice rather than a standardized amount of active compounds. There is no established best percentage for routine skin care.

70%

70% cream studied

A small human sunburn study tested this formula and found no benefit over placebo for treating sunburn. This is a study concentration, not a recommended target.

Choosing a strength: Choose a well-tolerated finished moisturizer rather than judging aloe by its front-label percentage.

Higher strengths: More aloe has not been shown to provide better sunburn treatment or sun protection.

Formula matters: Aloe juice, powders, and concentrated extracts are not equivalent at the same percentage.

Safety and sensitive skin

Common reactions

Usually comfortable; discontinue for a rash or persistent stinging.

Fragrance, alcohol or aloe itself can irritate; avoid raw plant latex on skin.

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.

On intact skin very little is expected to be absorbed, but ask the doctor managing your pregnancy rather than trusting a label, and raise oral aloe separately — that is a different question.

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 aloe vera in a particular vehicle.

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

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.

Aloe Vera:What should I choose aloe vera for?

Choose for a comfortable cooling gel, without expecting UV protection or faster healing.

Aloe Vera:How strong is the evidence?

A small controlled UV study found no sunburn-treatment or pigment benefit versus vehicle. Comfort from a gel does not establish accelerated healing of burns or wounds.
