Acetyl Tetrapeptide-3 Peptide

Mild to moderate barrier damage in daily home settings is currently the most common skin problem. This group of people mostly have the habit of excessive cleaning, frequent use of strong efficacy products, and long-term staying up late in skincare. Their skin is characterized by redness during seasonal changes, burning when exposed to heat, and a slight stinging sensation during daily skincare. Ordinary moisturizing products cannot relieve the dry and tight state. In such scenarios, the core function of acetyl tetrapeptide-3 peptide is to break the vicious cycle of "barrier damage → inflammation release → further barrier damage" by regulating inflammatory signals inside the skin.

In the application of daily repair toners, low concentrations can quickly penetrate into the gaps between the stratum corneum, inhibit the excessive release of pro-inflammatory factors such as IL-6 and TNF - α, and alleviate the hidden inflammatory state of the skin. Many repair toners that focus on maintaining the stability of sensitive skin are compounded with sodium hyaluronate to replenish moisture and soothe the redness and burning sensation of the skin. After continuous use for 7 days, the sensitive state of the skin turning red when exposed to air conditioning or changing seasons can be significantly improved.

Unlike traditional plant soothing ingredients such as purslane and centella asiatica, acetyltetrapeptide-3 has a more precise effect and does not pose additional sensitization risks due to impurities in plant extracts. Long term use also does not result in decreased tolerance.

In the application of daily repair essence, 0.01% concentration of this substance can act on the epidermal basal layer, accelerate the proliferation and differentiation of keratinocytes, promote the autonomous synthesis of ceramide, cholesterol and other barrier lipids, and rebuild a healthy stratum corneum structure from the root.

The 2025 clinical data of a third-party skin laboratory in China shows that after 4 weeks of continuous use of the repair essence, the transcutaneous water loss rate of the subjects has decreased by 28% on average, and the water locking capacity of the skin barrier has significantly improved.

The skin that was originally tingled with ordinary efficacy products can gradually tolerate mild sunscreen and makeup products, and completely get rid of the label of "fragile muscles". The daily repair essence launched by many sensitive muscle brands takes it as the core ingredient, replacing the traditional hormone soothing ingredients, achieving independent long-term barrier repair, and avoiding the risk of hormone face caused by long-term use of hormone ingredients.

In the emergency repair scene with seasonal sensitivity, it can quickly relieve the sudden redness and tingling. Many repair facial mask that focus on seasonal emergency have been added with acetyltetrapeptide-3. When the skin is suddenly sensitive, thick application for 15 minutes can quickly fade red and relieve, without bringing additional burden to the already fragile barrier. For the sensitive issue of "mask face" caused by long-term wearing of masks, it can also be accurately adapted. It can alleviate the skin inflammation caused by long-term mask covering, repair the damaged stratum corneum caused by friction, and improve the redness and acne problem in the mask coverage area after 2 weeks of continuous use. It is suitable for the daily commuting sensitive protection needs of urban residents.

For severely barrier damaged skin that has already shown obvious symptoms, such as sore face, hormone dependent dermatitis, and frequent red blood streaks, ordinary surface repair ingredients are no longer able to solve the problem of deep inflammation disorder. The multi-channel repair ability of acetyl tetrapeptide-3 peptide demonstrates irreplaceable value in such scenarios. In the barrier bad face scene caused by improper use of acid brushing and alcohol A, the skin will appear a large area of redness, peeling, tingling, and even accompanied by exudation symptoms.

At this time, the cuticle of the skin has been severely damaged, and ordinary thick repair face cream is easy to suffocate the skin, causing additional burden.

It can quickly regulate the excessive inflammatory response of the skin and accelerate the regeneration of the stratum corneum without sealing the skin. Many dermatologists recommend acid brushing repair products that are compounded with panthenol and squalane, which have a refreshing and non stuffy texture. They can quickly relieve the stinging sensation and accelerate the healing of damaged barriers. The repair cycle after acid brushing is shortened from the traditional 1-2 months to about 2 weeks, greatly reducing the risk of color fading on the face after acid brushing.

Clinical tracking data from a domestic medical beauty institution shows that among 120 subjects with barrier damage after acid brushing, 92% of them recovered their normal skincare status within 14 days after using repair products containing acetyltetrapeptide-3, without any subsequent rebound sensitivity.

In the repair scenario of hormone dependent dermatitis, the skin's immune barrier has been disrupted by hormones for a long time and is in a highly sensitive state. Many common repair ingredients may trigger strong rejection reactions. Its molecular structure is pure, without any excess impurities, and will not bring additional stimulation to the skin.

At the same time, it can gradually regulate the immune signals of the skin disorder, allowing the barrier function suppressed by hormones to gradually return to normal, helping hormone faced people smoothly pass the withdrawal period of the pan red hot stage. Unlike traditional hormone depletion therapy, using this substance to assist in repairing hormone face does not create new dependencies, ultimately achieving complete autonomous recovery of barrier function. This is also the core component of many mild hormone withdrawal programs currently used in dermatology clinical practice.

In the long-term repair scenario of bloodshot skin, many people's bloodshot skin is caused by long-term barrier damage, and the capillaries in the dermis layer are in a state of expansion for a long time, losing their elasticity. Acetyl tetrapeptide-3 peptide not only repairs the stratum corneum, but also acts on the superficial layer of the dermis, regulating the endothelial cell activity of capillaries and improving the excessive expansion of capillaries. Long term use can gradually fade superficial red blood vessels, reduce the frequency of frequent redness and burning of the skin, and fundamentally improve the sensitive characteristics of red blood vessels, rather than temporarily using ingredients to shrink blood vessels to mask symptoms.
