Products with Progeline

Trifluoroacetyl Tripeptide-2 is found in face and neck serums to prevent skin sagging. Here are some of my favorite products with progeline:

Benefits

This three-amino-acid peptide works by inhibiting the production of progerin, thereby reducing its detrimental effects on cellular structure and function. Manufacturers claim that Progeline can:

Preserve skin elasticity

Reduce sagging, particularly in areas such as the jawline

Diminish the appearance of wrinkles

Enhance overall skin texture and smoothness

Protect elastin, thereby helping to prevent sagging

Note that there is not much data to support these claims that I can find. If you find any good studies, please tell me in the comments.

I have seen this claim on the ingredient manufacturers website but cannot find any proof or publication to support the following:

“Clinical studies have shown promising results, with a 2% Progeline cream reportedly preserving skin elasticity and firmness by 20% in 28 days and lifting a sagging jawline by up to 10% in 56 days. Additionally, Progeline has been found to reduce progerin synthesis, inhibit matrix metalloproteinases (MMPs) and elastase, increase syndecan production, and contract collagen.”

Safety

According to the Environmental Working Group (EWG), Progeline, as Trifluoroacetyl Tripeptide-2, has a moderate safety profile with some concerns related to cancer, allergies, and developmental and reproductive toxicity. While it is generally considered safe for topical use, comprehensive safety data, particularly regarding long-term use and effects during pregnancy and breastfeeding, are limited.

There are no reports of allergic reactions, however, it is possible to have an allergic reaction to peptide ingredients.

The Cosmetic Ingredient Review (CIR) has not published any safety findings on Trifluoroacetyl Tripeptide-2, but the general consensus from other sources, such as the Cosmetics & Toiletries magazine and various ingredient databases, highlights that it is considered safe for topical use. Further research is necessary to fully understand its long-term effects

Side Effects

While Progeline is generally well-tolerated, some individuals may experience skin irritation or allergic reactions. It is recommended to perform a patch test before using any new skincare product if you commonly have skin allergies.

Pregnancy

The safety of Progeline during pregnancy and breastfeeding is not well-documented, so caution and consultation with a healthcare provider are advised.

Mechanism of Action

Progeline is an antiaging peptide that helps keep your skin looking young by blocking the production of a protein called progerin. Progerin makes cells age faster, leading to wrinkles and sagging skin. By stopping progerin from being made, Progeline helps maintain skin’s elasticity and firmness, keeping it smoother and less saggy.

What is Progerin?

Progerin is a defective variant of the lamin A protein, which is crucial for maintaining the structural integrity of the cell nucleus. In normal circumstances, lamin A undergoes a series of processing steps to become fully functional. However, in the case of progerin, a crucial processing step is skipped, resulting in a version of the protein that retains a hydrophobic oligoisoprene chain. This defective processing causes progerin to accumulate on the inner side of the nuclear envelope, disrupting its structure and function.

The accumulation of progerin is linked to the accelerated aging seen in Hutchinson-Gilford Progeria Syndrome (HGPS), a rare genetic disorder. In HGPS, a point mutation in the LMNA gene results in the production of progerin, leading to rapid aging and a significantly shortened lifespan. The structural distortions caused by progerin impair nuclear-cytoplasmic transport and increase cell death, contributing to the aging process.

Research suggests that progerin also plays a role in the natural aging process. The presence of progerin in individuals without progeria indicates that it may contribute to the gradual decline in cellular function and vitality as we age. Strategies to prevent progerin accumulation or enhance its clearance are being explored as potential anti-aging therapies.

Sun and Progerin

Sun exposure, particularly longwave ultraviolet A (UVA) radiation, has been shown to increase levels of progerin in the skin, accelerating the aging process. UVA radiation penetrates deeper into the skin compared to UVB, reaching the dermis and causing oxidative damage. This damage leads to alternative splicing of the LMNA gene, resulting in increased production of progerin. A study by Takeuchi and Rünger (2013) demonstrated that UVA exposure, but not UVB, induces progerin expression and causes HGPS-like nuclear abnormalities in skin cells

Conclusion

In conclusion, Progeline (Trifluoroacetyl Tripeptide-2) shows promise as an anti-aging ingredient by targeting progerin, a protein linked to accelerated aging. While initial studies and product claims are encouraging, further research is needed to fully understand its benefits and safety profile. As with any skincare ingredient, it is important to consider individual skin type and sensitivity when incorporating Progeline into a skincare routine.

DQH Can I use salicylic acid first and then vitamin C? It’s easy to create a skincare routine, but knowing how to use it is another thing entirely. In most cases, if you’re not getting the desired skin results, it could be due to the layering of conflicting ingredients. So, is it possible that salicylic acid and vitamin C are such ingredients? Or are these active ingredients the duo that’s been missing from your skincare routine? If you want answers, stick around because today we are going to explain the benefits of salicylic acid and vitamin C and how they can be used in your daily life. What are the benefits of salicylic acid for skin? Salicylic acid is one of the most commonly used beta hydroxy acids and is favored by many people with oily, acne-prone skin. This acid is derived from willow bark, and unlike its water-soluble relatives (called alpha-hydroxy acids), salicylic acid is oil-soluble, which means it can penetrate deeper into the lower layers of the skin. Once it reaches the lower layers, it can help unclog pores of excess sebum, dirt, bacteria, debris, and impurities. This results in clearer skin tones and greater definition. Not only does salicylic acid benefit the underlying layers, but the outer surface of the skin benefits as well. When applied to the skin, salicylic acid removes the buildup of dead skin cells. This is accomplished by breaking the bonds that hold dead cells to the surface. Over time, this can cause the complexion to look dull and prone to acne, blackheads, and other blemishes. If you’d like to learn more about salicylic acid and how it can improve your skin, check out this dedicated blog post from a beauty insider. What are the benefits of vitamin C for skin? Vitamin C is considered one of the most powerful antioxidants, which means it is very effective at fighting free radicals and preventing them from causing further skin damage. Examples of free radicals include pollution, central heating, UV rays and harsh climate. They attack proteins, fats and cell membranes as soon as they come into contact with the skin, causing signs of premature aging such as fine lines and wrinkles as well as hyperpigmentation, flaky patches of skin and loss of elasticity. Many people usually prefer to use vitamin C in their morning routine as this ingredient gives the complexion a radiant glow. You’ll also find that vitamin C can target areas of hyperpigmentation, plumping the skin and reducing the appearance of fine lines and wrinkles. The thing about vitamin C is that there are a lot of outdated studies going back to the 1950s that describe vitamin C as an unstable skin component. Thanks to improvements in modern technology, this is no longer the case as all products now contain a stable form of vitamin C. Visit The Beauty Insider to learn more about vitamin C. So please check out our blog post. Can I use salicylic acid first and then vitamin C? Yes, you absolutely can. In fact, it’s thought that using salicylic acid before using vitamin C ensures it penetrates faster and works faster. This is an efficient way to utilize two power sources, and the reason has to do with pH. For example, the skin’s natural pH is about 4.7, making it slightly acidic. Salicylic acid and vitamin C are also both acidic, and you’ll find that vitamin C is absorbed quickly into the skin. Therefore, using salicylic acid beforehand can increase the acidity of the skin and allow vitamin C to penetrate into the skin faster. While this is considered an effective way to combine two powerful ingredients, you need to be aware of your skin type and how it reacts to certain active ingredients. Even people with perfect, normal skin can experience skin sensitivity and irritation. Therefore, always consult a doctor or dermatologist before using any new products on your skin. It’s also important to follow skin application rules. In this case, you need to use the product correctly to ensure you get the best results for your skin. If you’re not sure what I mean, the basic rule for skin is to start with the thinnest consistency and work your way up to the thickest consistency. This prevents a barrier from forming on the surface, preventing other active ingredients from penetrating the skin. Can I use salicylic acid at night and vitamin C in the morning? Yes, absolutely, this is considered the most effective way to get returns without any adverse side effects. This is because there is enough time between applications to ensure that the skin’s pH levels return to balance. You’ll also find that Vitamin C is rich in antioxidants and is perfect for use in the morning to ensure your skin is protected and looking its healthiest. Due to the small size of salicylic acid molecules, it is an acid that is able to reach the deepest parts of the skin. While this is effective at keeping skin clear, it also increases the risk of irritation and photosensitivity. Therefore, many people prefer to use powerful BHAs in their evening routine without exposure to UV rays, pollution, or harsh weather. Warning: If you avoid using sunscreen every day, none of these ingredients will do what your skin needs. The combination of chemical peels and powerful ingredients increases the risk of further damage to the skin’s surface. Use SPF 50 every day to keep your skin protected and your lipid barrier healthy, even on cloudy days, keeping your skin in top condition.
