Not All Hyaluronic Acid Is Equal

Herworld (Singapore) - - TO KNOW -

The su­per­hero mois­tur­is­ing in­gre­di­ent holds up to 1,000 times its weight in water. And it’s in a lot of skin­care. But it’s not the same in every prod­uct. The molec­u­lar weight, or size of the hyaluronic acid (HA) mol­e­cules, mat­ters. The higher the molec­u­lar weight, the larger the mol­e­cules.

Sothys says larger HA mol­e­cules sit on top of skin, so the hy­drat­ing ef­fect can be seen right away, while smaller mol­e­cules sink into skin, so the hy­dra­tion lasts longer.

The brand uses both mol­e­cule sizes in its Hy­dra 3HA Hyaluronic Acid range. The In­ten­sive Hy­drat­ing Serum for all skin types has low molec­u­lar weight HA. The two moisturisers (Hy­drat­ing Com­fort Youth Cream for nor­mal to dry skin, and Hy­drat­ing Youth Cream for nor­mal to com­bi­na­tion skin) and the Hy­dra-smooth­ing Mask for de­hy­drated skin have high molec­u­lar weight HA. Used to­gether, they pro­vide longer­last­ing and bet­ter hy­dra­tion. $113-$185
