There is not only one type of hyaluronic acid, both—it is available in totally different sizes that are capable of penetrate totally different layers of the pores and skin. “Every molecule is assigned a molecular weight, which inversely pertains to how deep the molecule can penetrate the pores and skin,” says Rina Allawh, MD, a board-certified dermatologist at Schweiger Dermatology Group in King of Prussia, PA. The smaller the molecule, the deeper into the pores and skin it is capable of penetrate.
It might look like you’d all the time need to go for the hyaluronic acid with the bottom molecular weight doable, however that is not all the time the case. “The benefit of higher-molecular-weight hyaluronic acid serums are the anti-inflammatory and soothing properties, because it types a sturdy movie with the highest layer of the pores and skin,” says Allawh. “A low-molecular-weight hyaluronic acid serum is extra more likely to have a long-lasting anti-wrinkle and regenerating impact and works within the deeper ranges of the pores and skin. As you’ll be able to think about, lower-molecular-weight hyaluronic acid serums are capable of lock within the moisture within the connective tissue of the pores and skin and, in consequence, stimulate firming results.”
