BeautyPro ROSE Infused Sheet Face Mask

On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations.

Typical use levels in a formula run about 1-5%.

It's a very large molecule that doesn't meaningfully get through intact skin and the CIR Expert Panel has concluded it's safe at current use levels.

True allergy is rare and there are only two published cases from internal/mucosal exposure rather than anything topical. Most of the scary internet content about Carrageenan is actually about poligeenan (also called "degraded carrageenan").

Poligeenan is a deliberately acid-broken down version that isn't food or cosmetic grade.

Wakame prefers cold and temperate oceans. It is used in Japanese and Korean cuisine (yummy!).

Those sugars help hold water and form a light film on the skin's surface, giving it humectant and mild-barrier supporting properties.

The best human data is a small Korean study where a cream with 10% extract upped skin hydration about 14% over placebo and cut water loss through the skin for up to eight hours.

Beyond this study, most of the anti-aging and anti-inflammatory claims come from mouse and cell studies; these studies found that topical kelp sugars preserved collagen in aging mice and the extract calmed UVB-triggered inflammation markers in cultured skin cells.

Though this sounds promising, it isn't the same as proof on human faces.

Industry data shows this ingredient is usually used anywhere from 0.0005% - 5%. Most leave-on products sit well under 1% and the 5% end mostly shows up in bath products.

Allergy-risk for this ingredient looks low as well. A cream with 10% extract patch-tested on 25 people caused no irritation and there have been no sensitization reports either.

There is one real allergy report on "laminaria" that involves medical cervical dilators made from whole dried kelp stems inserted internally; though this is a very different exposure from a few tenths of a percent in a serum.

When exposed to air, these two compounds become strong allergens. This ingredient exhibits cytotoxicity at low concentrations; amounts of 0.25% have been shown to damage skin cells.

A study from Japan found this ingredient caused lavender sensitivity after widespread exposure.

Lavender essential oil has some antimicrobial, antibacterial, and anti-inflammatory properties. However, the cons of this ingredient may outweight the pros.

More research is needed to confirm lavender essential oil's effects when used in aromatherapy.

Lavandula Angustifolia is known as the English Lavender and famous for creating purple fields in Provence, France.

Because it has a neutral charge, it is compatible with a wide range of ingredients and stays stable across a broad pH range/water hardiness conditions.

Patch testing has shown it to have the lowest irritation potential among common cleansing surfactants (like SLS).

Typical use levels range from 5-20% in rinse-off cleansers.

One thing worth knowing: The American Contact Dermatitis Society named the parent family, alkyl glucosides, "Allergen of the Year" in 2017. The prevalence of allergy is pretty low but be sure to patch test if you've reacted to "gentle" or sulfate-free cleansers before.

This ingredient is fungal acne safe because the fatty alcohol portion of this ingredient is not within the C11-24 chain length that Malassezia can metabolize.

These compounds protect your skin two ways:

1) They fight off free radicals, or the unstable molecules from things like sun and pollution that age and damage skin.
2) They help calm inflammation by switching off the chemical signals that tell skin to get red and irritated.

Lab studies also suggest that rosmarinic acid may help protect collagen and slow sugar-related damage to it.

The Cosmetic Ingredient Review has concluded rosemary-derived ingredients to be safe when formulated to be non-sensitizing.

Rosemary can occasionally cause allergic contact dermatitis (due to carnosol), so be sure to patch test if you have reactive or fragrance-sensitive skin.

Antioxidant components in chamomile make it an effective ingredient to help slow the signs of aging. Antioxidants help fight free-radical molecules, or molecules that may damage your skin.

Essential oils from chamomile have been found to improve wound healing due to its antimicrobial properties.

Ancient Greeks and Egyptians used Chamomile to treat skin redness and dryness. Chamomile has also been used to help treat stomach issues.

Vitamins C and E are potent antioxidants and may help with anti-aging. The fatty acids are emollients that help soften and hydrate your skin.

Another potent vitamin found in rosehip is Vitamin A, or retinol. Retinol encourages collagen production in the skin.

Rosehip extract may help with brightening the skin. Several components, such as beta-carotene, are able to reduce pigmentation caused by sun damage.
