Hyaluronic acid is a common ingredient in skincare products. It's used chiefly in moisturizing creams, lotions, and serums because of its ability to hydrate and plump the skin.
Because it has "acid" in its name, it's often mistaken for an exfoliating ingredient, much like salicylic acid or glycolic acid. However, hyaluronic acid has little in common with alpha hydroxy or beta hydroxy acids such as these. Hyaluronic acid attracts water from within the dermis and moves it along to the skin surface, the epidermis. Hyaluronic acid and other glycosaminoglycans also play a role in skin elasticity and tone, cell metabolism, regeneration, and healing.
As you age, hyaluronic acid levels in the skin naturally taper off. Your skin doesn't manufacture it as effectively as it used to. That is partly why the skin becomes thinner and drier as you get older. Hyaluronic acid levels in the skin begin a steep decline after age 40.
Apply a topical hyaluronic acid product and it will help pull moisture from the deeper layers of the skin to infuse the top layers of the skin with moisture. If you live in a humid area, it can also help pull water from the air into your skin.
Hyaluronic acid products also help reduce trans-epidermal water loss. This is another way of saying that it helps keep the water in your skin, rather than letting it evaporate out into the air.
Bumpy skin is actually called keratosis pilaris, and it is a common—and harmless—skin condition that is most typically found on the upper arms and thighs. Bumpy skin is caused by the buildup of keratin proteins which plug hair follicles, thus resulting in tiny bumps and often rough, dry skin. Usually, this condition begins in childhood and often dissipates with age.
Sometimes bumpy skin are caused by clogged pores that are deep under your skin.
Jojoba oil and rose hip oil are good for improving sebum texture and keeping in moisture for healthier skin. Ingredients that help exfoliate dead skin cells and increase new skin cell production, such as Vitamin A/Retinol, glycolic acid, and salicylic acid, are good for keeping skin smooth as well.
hyaluronic acid may be effective for bumpy skin, but there are many other factors that may affect whether this ingredient would work on your skin or if there are better ingredients that may work for you. Take this skin quiz to find the best ingredients for your skin and build your skincare routine.
