Bella Aura Skincare Hydra Revive Treatment

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

These "skin-like" liquid crystals improve skin barrier integrity and promote the delivery of actives into the skin.

This ingredient is well-tolerated and has no significant sensitization data.

Because it is derived from the fatty acids in olive oil, this ingredient may not be fungal acne safe.

This ingredient is also known as part of Olivem 1000, with Cetearyl Olivate being the other part.

According to a manufacturer, this ingredient helps preserve the natural microbiome of skin. Having a healthy microbiome helps keep our skin healthy and protects against harmful bacteria.

Please note, having a healthy microbiome is different from fungal acne; a healthy microbiome includes small amounts of yeast that normally live on your skin without causing problems.

Fungal acne happens when one type of yeast (Malassezia) grows out of control. This is usually because it's feeding on certain oils or fatty acids. Due to the olive oil base, this ingredient may not be fungal acne safe.

In cosmetics, HJE works mainly to soften skin, reinforce the barrier, and lock in moisture by reducing water loss. This ingredient also holds onto the skin even after rinsing which is why you'll see it in cleansers or wipes.

There's a decent clinical backing for the moisturizing claims: a small controlled study found that pairing HJE with glycerin lowered transepidermal water loss significantly than glycerin alone (and this effect lasted up to 24 hours).

Follow-up work showed HJE appear to "trap" glycerin in the film they form on skin to boost its hydrating power.

Typical use levels are low: the glycering-synergy research used around 1.25% (a common pairing is roughly 1.25% HJE and 3.75% glycerin).

This ingredient has been found safe as used in cosmetics with low irritation risk.

As for fungal acne, the fatty acids and alcohols in jojoba fall in roughly the C18-24 range. This overlaps the C11-24 window that Malassezia yeast can feed on in lab studies, so this ingredient may not be fungal acne safe.

This ingredient is considered hypoallergenic and non-toxic. Cellulose Gum can be found in cosmetics, food, and other household goods such as paper products.

Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

PHAs are more gentle than AHAs due to their larger structure. They do not penetrate as deeply as AHAs and take a longer time to dissolve dead cells. Studies show PHAs do not cause as much irritation.

Gluconolactone has some interesting properties:

In a 2004 study, Gluconolactone was found to prevent UV damage in mouse skin cells and has not been found to increase sun sensitivity. However, we still recommend wearing SPF daily.

This ingredient is is an created by reacting gluconic acid with an alcohol.

Caprylhydroxamic Acid is often used with natural antimicrobial products as an alternative to preservatives.

However, this exfoliating effect only happens at high concentrations (20%) which can be hard to find in cosmetic products.

Due to this, citric acid is usually included in small amounts as a pH adjuster. This helps keep products slightly more acidic and compatible with skin's natural pH.

In skincare formulas, citric acid can:

While it can provide some skin benefits, research shows lactic acid and glycolic acid are generally more effective and less irritating exfoliants.

Most citric acid used in skincare today is made by fermenting sugars (usually from molasses). This synthetic version is identical to the natural citrus form but easier to stabilize and use in formulations.

Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.

It is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.

Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.

We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.
