The word acid sounds intimidating but hyaluronic acid is probably the friendliest acid. It is naturally present in the human body, especially in the fluids in the eyes and joints. Hyaluronic acid is a humectant (attracts/binds moisture to the skin) that can be found in the ingredients list of a lot of moisturizers. It is not anti-aging per say, but since it is a humectant naturally present in our body, it gets absorbed easily and provide moisture, which in turn makes the skin look plump, supple and firm.
Skin Type: Every skin type! Dry, oily, combination, sensitive, aging etc.
Purpose: It boosts the skin’s moisture content, prevents moisture loss and improves elasticity by keeping your skin healthy and hydrated. While it doesn’t have any fancy effect/purpose aside from hydration, or perhaps because of it, this ingredient is great for every skin type and can be used with anything. You don’t ever have to worry about this conflicting with any active ingredients in your other products.
My Beauty Diary Hyaluronic Acid Moisturizing Mask
My take: The mask is a thin smooth sturdy cotton sheet. The liquidy essence has no scent and it absorbs easily with no residue. There is enough essence leftover to use next day, or you can layer it all on. Unlike some masks where your skin might feel greasy or stuffy after you rubbed on the leftover serum, the skin feels moisturized but not stuffy or greasy at all even after I piled on all the serum. The skin feels very hydrated after use and stayed hydrated for the next few days. There is no other effect such as reduced redness etc, but it’s a hydrating mask that is appropriate for all skin type from dry to oily to sensitive.
Etude House Essential Mask Sheet, Hyaluronic Acid
My take: It is a thin smooth cotton sheet that adheres well to the face. Usually sheet masks are a bit larger than my face but this is just barely enough. The liquid have a mild fresh clean scent but it was not irritating. It’s a bit thicker and more of a serum than essence, but it sinks in pretty well. My skin is left hydrated and stays hydrated the next day.
Of the two sheet masks, I prefer My Beauty Diary more because the essence is more lightweight, more appropriate for my skin type and this summer weather. It also have no fragrance (hyaluronic acid itself is scentless I believe). While neither irritated my skin, I’m wary about fragrance since I’ve been dabbling in heavy duty peels and want everything else to be as calming or least irritating as possible. There really isn’t much to say about these masks, because they have just one purpose — to hydrate. If you have SUPER sensitive skin or just want something that is really good at providing hydration deep into the skin, My Beauty Diary Hyaluronic Acid mask is a worthy buy at ~$2 per sheet.
