Growth factors are currently a popular ingredient in skincare, and for good reason. These small molecules are natural proteins in our bodies that aid in cellular renewal by signaling cellular health and repairing damaged cells. As we age, our body’s natural supply of growth factors decreases, making serums infused with growth factors beneficial. I recently tried Le Mieux’s TGF-B Booster, a potent growth factor serum, and here’s why I loved it.
The Benefits
If you’re unfamiliar with Le Mieux, the brand was established in 2004 by Janel Luu and a team of scientists, physicians, and chemists. One of the brand’s notable features is its use of hyaluronic acid as a base instead of water in its formulas. The TGF-B Booster, a top-selling growth factor serum, follows this trend.
Understanding how growth factors function can be complex, but the brand simplifies it by likening them to a recharge for aging skin. These growth factors send signals to promote collagen production and prevent skin from sagging, loosening, and wrinkling. Le Mieux recommends growth factors for individuals over 30 experiencing signs of aging and environmental damage.
This serum is enriched with palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, and palmitoyl tripeptide-1. Palmitoyl tripeptide-5, also known as transforming growth factor (TGF), acts as a “collagen protector” by safeguarding existing collagen and preventing its breakdown. This results in smoother skin with reduced fine lines and wrinkles, as well as a more supple appearance. Additionally, the serum boosts the effectiveness of other products layered on top of it and is suitable for all skin types, including sensitive skin. It’s important to note that the serum contains fragrance, but the brand assures it’s a “proprietary natural oil blend” rather than synthetic fragrance.
Key Ingredients
Hyaluronic acid, hydrolyzed sodium hyaluronate, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, palmitoyl tripeptide-1, and niacinamide
How to Use It
After cleansing your face, apply three to five drops of the serum on your face and neck. The silky, milky texture absorbs quickly without leaving a greasy residue. You can use it twice daily, in the morning and evening. For added benefits, layer this serum with Le Mieux’s Hyaluronic Booster, which utilizes various weights of hyaluronic acid to hydrate and plump the skin. This combination provides a dewy finish without greasiness, keeping the skin hydrated throughout the day—ideal for my mid-30s skin.
