YTBIO's Acetyl Heptapeptide-4 (98%) is a high-purity cosmetic active peptide ingredient produced using advanced biosynthetic technology. It offers excellent compatibility and is suitable for use in skincare products designed for anti-aging, moisturizing, and skin repair.

Acetyl Heptapeptide 4 is an active cosmetic peptide frequently used in high-end skincare products as a probiotic-inspired ingredient. Its molecular structure consists of seven amino acids, and it is modified via acetylation to enhance stability and transdermal absorption. It strengthens the skin barrier by promoting microbial balance and diversity and increasing beneficial bacteria, thereby boosting the skin's natural defense system.

Regulates microbiome balance

Strengthens the physical barrier

Inhibits inflammatory responses

① Microbial Barrier

It promotes the balance and diversity of the skin microbiota and increases the proportion of beneficial bacteria, thereby helping to activate the skin's innate defense system. Rather than directly applying live bacteria to the face, it fosters a more favorable environment for beneficial bacteria to thrive.

② Physical Barrier

It has been observed to enhance corneocyte cohesion and reduce skin scaling. It provides a barrier-protective effect, helping to minimize transepidermal water loss (TEWL) and prevent dryness.

③ Immune / Anti-inflammatory

In vitro studies demonstrate that it inhibits the activation of Kallikrein-5 (KLK5, a serine protease) and PAR-2. The overactivation of PAR-2 ​​by KLK5 is a key factor in triggering inflammation and itching, as well as compromising the skin barrier; Acetyl Heptapeptide-4 helps alleviate inflammation and itching, and is also effective in reducing scalp inflammation, itching, and flaking.

It is particularly suitable for skincare products designed for sensitive skin, offering rapid relief from redness and discomfort. It can be incorporated into any formulation to strengthen the skin barrier and prevent dehydration.

Storage Conditions
Store in a sealed container, protected from light, in a dry place at 2–8°C. For long-term storage, freezing at -15 to -20°C is recommended.

Formulation Recommendations: It is often paired with barrier-repairing ingredients (such as ceramides, cholesterol, and panthenol) and prebiotics/postbiotics (such as inulin and alpha-glucan oligosaccharides) to nourish the skin microbiome and support barrier repair.

Safety: Acetyl Heptapeptide-4 is suitable for long-term, regular skincare use. It is generally considered to have good tolerability, though individual responses may vary.

Is a higher concentration always better?

It is an ingredient that is effective at low dosages; "low" does not mean ineffective, nor does "high" necessarily mean better. The optimal concentration depends on the product positioning and the overall formulation.

Can it cure eczema or dandruff?

While the mechanisms involved are indeed related to these issues, it is a cosmetic ingredient designed to soothe and protect the skin, not a pharmaceutical drug. It cannot cure skin diseases; please consult a medical professional if you have a diagnosed skin condition.
