This topical formula is the most comparable to actual lip filler, IMO. (I don’t personally have any filler at this point in my life, but I’ve talked to other beauty fans who do, and they agree.) Like the previous product, DermInfusions contains four molecular weights of HA to usher water into each layer of the lip skin. Trehalose, another humectant, adds even more water-binding properties to plump the lips with moisture.
It also contains a peptide blend (palmitoyl tripeptide-38 and palmitoyl tripeptide-1, to be specific) to help stimulate collagen and give lips a firmer appearance. Finally, the treatment includes known skin soothers—ectoin, bisabolol, and centella asiatica—to heal chapped lips, prevent dryness, and protect the skin from environmental aggressors (which can make lips appear dull).
You can read my full review of the lip treatment here for more info, but overall, this is my favorite option. I love how instantly full and vibrant my lips look after just a few minutes, and without any additional swipe of color. It does come with a slight tingle, but the sensation goes away after about a minute. The finish reads just like a nonsticky lip oil—I’m obsessed.
The only downside I can think of is that it’s less inconspicuous than other options on this list. It looks high-tech, and it’s a relatively large pen, so you can’t really stash it in your pocket or small handbag like you might a standard lip balm. I personally don’t mind the design—I’ll happily gush about the effective formula to anyone who asks me what I’m applying.
