PEH Balance Exfoliating & Smoothing Face Serum Exfoliating Therapy

• It’s the most researched AHA with the most proven skin benefits
• It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
• It can help skin’s own collagen production that results in firmer, younger skin
• It can fade brown spots caused by sun damage or PIH
• Choose a product where you know the concentration and pH value because these two greatly influence effectiveness
• Don’t forget to use your sunscreen (in any case but especially so next to an AHA product)
• Slight stinging or burning with a stronger AHA product is normal
• If your skin is very sensitive, rosacea prone choose rather a BHA or PHA product

• Mandelic acid is an AHA that comes from bitter almond
• It can gently lift off dead surface skin cells and make the skin more smooth and even
• It has antibacterial properties
• It’s promising against acne and post inflammatory hyperpigmentation
• It’s light sensitive, so choose a product with opaque packaging

The unfancy name for it is lye. It’s a solid white stuff that’s very alkaline and used in small amounts to adjust the pH of the product and make it just right. 

For example, in case of AHA or BHA exfoliants, the right pH is super-duper important, and pH adjusters like sodium hydroxide are needed.

A naturally occurring fructose polysaccharide found in the roots and rhizomes of several plants, for example, chicory. It is used in skincare for its prebiotic activity, meaning that it reduces the growth of bad bacteria in favor of friendly microorganisms naturally present on the skin.

Fancy name for fruit sugar. It has nice water-binding properties and helps to keep skin hydrated. 

A fancy name for sugar. Luckily when you put it on your skin it's good for you not like when you eat it. :) It has water-binding properties, which means that it helps to keep your skin nice and hydrated. 

A sugar beet-derived amino acid derivative with nice skin protection and moisturization properties. Betaine's special thing is being an osmolyte, a molecule that helps to control cell-water balance.  It is also a natural osmoprotectant, meaning that it attracts water away from the protein surface and thus protects them from denaturation and increases their thermodynamic stability. 

It also gives sensorial benefits to the formula and when used in cleansers, it helps to make them milder and gentler. 

Though its name says acid, it's not really an exfoliant. It's a plant extract with some antioxidant properties. Its main thing in cosmetic products is to neutralize the metal ions in the formula (that usually get into there from water) that would otherwise cause some not so nice changes.  It's a natural alternative to sometimes bad-mouthed chelating agents, EDTAs.

A cellulose (the big molecule found in the cell wall of green plants) derivative that is used as an emulsion stabilizer and thickener. 

It’s one of those little helper ingredients that makes sure the product stays the same over time. No color change or anything like that. It does so by neutralizing the metal ions in the formula (that usually get into there from water) that would otherwise cause some not so nice changes. 

It's one of the most commonly used thickeners and emulsion stabilizers. If the product is too runny, a little xanthan gum will make it more gel-like. Used alone, it can make the formula sticky and it is a good team player so it is usually combined with other thickeners and so-called rheology modifiers (helper ingredients that adjust the flow and thus the feel of the formula). The typical use level of Xantha Gum is below 1%, it is usually in the 0.1-0.5% range. 

Btw, Xanthan gum is all natural, a chain of sugar molecules (polysaccharide) produced from individual sugar molecules (glucose and sucrose) via fermentation. It’s approved by Ecocert and also used in the food industry (E415). 

A natural polymer (big molecule from repeated subunits) that can be found in the cell wall of green plants. It is a natural and sustainable helper ingredient that can improve the absorption of the formula and it also reduces oiliness on the skin. It is also used as a sensory additive and thickening agent.

We don't have description for this ingredient yet.

• It’s a polyhydroxy acid (PHA), that is often referred to as next generation AHA
• It gently lifts off dead skin cells form the skin surface making skin smooth and even
• In the long term it provides anti-aging benefits, like increased skin thickness and decreased wrinkles (though a tad less than even more proven superstar AHAs)
• It’s a great moisturizer and even helps to repair impaired skin barrier
• It’s antioxidant, and does not make your skin more sensitive to the sun
• It can be used even if your skin is very sensitive, rosacea prone or if you are post cosmetic procedure

A helper ingredient that helps to make the products stay nice longer, aka preservative. It works mainly against fungi. 

It’s pH dependent and works best at acidic pH levels (3-5). It’s not strong enough to be used in itself so it’s always combined with something else, often with potassium sorbate.
