What Is Oligopeptide-133 Tripeptide-44 Tyrosinyl D-Alanyl Tripeptide-76?
Oligopeptide-133 Tripeptide-44 Tyrosinyl D-Alanyl Tripeptide-76 is a lab-made chain of 34 amino acids pieced together from several smaller peptides including Oligopeptide-133, Tripeptide-44, tyrosine, D-alanine and Tripeptide-76. Because it is synthetic it does not come from plants or animals, which helps keep the material consistent from batch to batch. Peptide technology took off in skin care through the late 1990s and early 2000s when researchers learned these tiny protein fragments could signal the skin to look and feel healthier. This particular peptide blend was developed during that period as scientists combined different short peptides to create a multitasking skin conditioner.
Manufacturing starts with solid-phase peptide synthesis, a step-by-step process where each amino acid is added in a set order on a resin bead. After the 34-unit chain is complete it is cut from the bead, purified and then freeze-dried into a fine powder. The finished ingredient dissolves easily in water-based formulas making it simple to add to a wide range of products.
You’ll most often spot Oligopeptide-133 Tripeptide-44 Tyrosinyl D-Alanyl Tripeptide-76 in anti-aging serums, firming creams, sheet masks and targeted eye treatments. Brands use it when they want to boost hydration, support smoother texture and give tired skin a refreshed look.

Who Can Use Oligopeptide-133 Tripeptide-44 Tyrosinyl D-Alanyl Tripeptide-76
This peptide is considered gentle enough for most skin types including dry, normal, combination, oily and sensitive because it is water based and non greasy. Those with extremely reactive or allergy-prone skin should still look closely at the full product formula since irritation is usually triggered by added fragrance or preservatives rather than the peptide itself.
Because the ingredient is fully synthetic and contains no animal by-products it suits both vegetarians and vegans.
Current research shows no specific risks for pregnant or breastfeeding women when the peptide is used topically in cosmetic amounts. That said this is not medical advice and anyone who is expecting or nursing should have their doctor review their skin care routine to be certain it matches their individual needs.
The peptide does not make skin more sensitive to sunlight so it will not raise the chance of sunburn. Still use daily sun protection to shield skin from routine UV damage.

Comedogenic Rating
Rating: 0
This peptide is completely water soluble and carries no oily residues so it cannot mix with sebum or block pores. Lacking fats waxes or heavy silicones it sits at the bottom of the comedogenic scale.
Because of this it is considered suitable for acne-prone or breakout-prone skin.
Any chance of clogged pores would come from richer co-ingredients in the final formula not from the peptide itself.
