Ingredient review
Allantoin PABA
INCI: Allantoin PABA
Allantoin PABA combines soothing allantoin with PABA, a former sunscreen ingredient, but PABA is rarely used today due to safety concerns and allergy risks.
In plain English
Allantoin PABA is a lab-made ingredient that pairs allantoin (a gentle skin soother often found in diaper creams) with PABA (a chemical that was once common in sunscreens but is now mostly avoided because it can cause skin irritation and allergic reactions). In skincare, it may help calm irritated skin while offering a small amount of UV protection, but the PABA part makes it less popular in modern products.
Quick decision guide
Useful, but context matters
Allantoin PABA is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Allantoin PABA.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic compound formed by combining allantoin, a soothing agent derived from the comfrey plant or made in a lab, with para-aminobenzoic acid (PABA), a chemical historically used as a UV filter in sunscreens.
How it works
Allantoin helps soften and soothe the skin by promoting gentle exfoliation and supporting moisture retention. PABA absorbs UVB rays, but its use has declined because it can cause skin sensitivity and staining of clothing. Together, the compound aims to provide both calming and photoprotective benefits, though the PABA component is now considered outdated.
Pros
Soothing properties
Allantoin is well-known for calming irritated skin and supporting gentle healing, making this compound potentially helpful for post-sun or sensitive skin.
Dual function
Combines soothing and UV-absorbing abilities in one ingredient, which could simplify formulations for products like after-sun lotions.
Cons and cautions
PABA safety concerns
PABA has been linked to skin allergies, irritation, and potential DNA damage under UV exposure, leading to its decline in sunscreen use.
Outdated ingredient
Most modern sunscreens avoid PABA due to safety and cosmetic issues (e.g., staining clothes), so this compound is rarely found in new products.
Best for
- People with dry or mildly irritated skin looking for a soothing ingredient
- Those who tolerate PABA well and want a dual-action soothing and UV-filter ingredient
Use caution if
- Individuals with sensitive or allergy-prone skin, especially those with known PABA sensitivity
Usage tips
Safety summary
Allantoin PABA is generally considered safe for topical use at low concentrations, but the PABA component carries a risk of allergic reactions and skin irritation. It is not recommended as a primary sunscreen ingredient due to outdated safety profiles.
Research notes
Research on allantoin supports its soothing and moisturizing benefits. PABA's UV-absorbing properties are well-documented, but studies also highlight its potential to cause contact dermatitis and phototoxicity, leading to its replacement by safer UV filters.
Common label clues
