What Is Dipeptide-30?
Dipeptide-30 is a lab made peptide built from two naturally occurring amino acids, histidine and proline. Peptides are short chains of amino acids that can signal or support the skin in various ways, and this particular pair was selected for its skin friendly qualities. The ingredient was developed as part of the wider interest in bioactive peptides that began in the late twentieth century when researchers discovered that specific amino acid sequences could help skin look and feel healthier. Using solid phase peptide synthesis, chemists link histidine and proline in a controlled environment, purify the result, then dry it to a stable powder that can be blended into cosmetic bases.
Because of its gentle nature and compatibility with other skincare staples, Dipeptide-30 is found in lightweight serums, eye creams, anti aging formulations, hydrating masks and everyday moisturizers. Brands choose it when they want to add a touch of targeted skin support without resorting to heavy oils or strong actives.
Dipeptide-30’s Cosmetic Benefits/Uses
In formulas designed for daily use Dipeptide-30 serves one clear role.
Skin conditioning: Dipeptide-30 helps the skin surface feel smoother and more supple. By supporting the skin’s natural barrier it can improve softness and give products a pleasant after feel, making the overall routine more enjoyable.
Who Can Use Dipeptide-30
Dipeptide-30 is generally suitable for all skin types, including dry, oily, combination and sensitive skin because it is a mild conditioning agent that does not contain known irritants or pore clogging oils. People with very reactive or allergy-prone skin should still monitor how their skin responds, but most users find it gentle and non-sensitising.
The ingredient is produced entirely through laboratory synthesis, so no animal-derived materials are involved. This makes it appropriate for vegans and vegetarians who prefer cruelty-free and animal-free cosmetic ingredients.
Current research shows no specific risks for pregnant or breastfeeding women when Dipeptide-30 is applied topically. That said, this information is not medical advice and anyone who is pregnant or nursing should discuss new skincare products with a qualified healthcare professional to be on the safe side.
Dipeptide-30 does not increase photosensitivity, so it can be used in both morning and evening routines without making skin more prone to sunburn. As with any skincare ingredient, pairing it with daily sunscreen is still recommended for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical Dipeptide-30 can vary from one person to another. The issues listed below are possible outcomes rather than expected ones. When the ingredient is formulated correctly most users will not notice any negative effects.
- Mild redness or warmth shortly after application
- Temporary stinging or tingling on very sensitive skin
- Itching or minor irritation if combined with other strong actives
- Allergic contact dermatitis in individuals with a specific peptide sensitivity
If any of these reactions occur discontinue use and seek advice from a dermatologist or healthcare provider.
Comedogenic Rating
Rating: 0 / 5. Dipeptide-30 is a small, water-soluble peptide with no oily or waxy components, so it does not block pores. Because it stays on the skin surface and is usually delivered in lightweight bases it carries virtually no risk of triggering comedones.
Suitable for acne-prone or breakout-prone skin.
As with any ingredient, the overall formula matters; heavy oils or rich butters in the same product could influence how pore friendly the final product feels.
Summary
Dipeptide-30 is a lab-crafted two-amino-acid peptide used mainly for skin conditioning. It smooths and softens by supporting the outer skin barrier and giving formulas a silky after feel, all without adding grease or strong actives.
While effective, it is still a niche ingredient appearing mostly in specialty serums, eye creams and lightweight moisturizers rather than in every mass-market product. Its gentle profile, vegan origin and non-comedogenic nature make it attractive to formulators looking for mild performance boosters.
Current data shows it is low risk for irritation or sensitization, making it safe for most skin types. That said, skin is individual so it is always wise to patch test any new product containing Dipeptide-30 before full-face use.
