Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservatives
Allantoin is a soothing ingredient known for its protective and moisturizingg properties. Because of this, it is often added to products with strong active ingredients.
Studies show higher concentrations of this ingredient can promote wound healing.
Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity.

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

It is found naturally in sugar cane but the form used in skincare is usually synthetic for purity and stability.
Glycolic acid removes the top layer of dead skin cells to allow newer and fresher ones to emerge.
AHAs work by breaking down the structural “glue” that holds old skin cells in place. When that buildup is gone, your skin can renew itself more efficiently.
Research also shows glycolic acid stimulates collagen production, helping to firm and thicken the skin over time. This is one of its biggest advantages over other AHAs.
Overall, glycolic acid helps with:
Fun fact: Glycolic acid boosts skin hydration by helping it produce molecules that increase hyaluronic acid naturally.
To work best, glycolic acid products should have a pH between 3-4 (that’s where exfoliation is most effective but still gentle on skin).
The pH and concentration of a product are key to its effectiveness:
It is normal to feel a slight stinging sensation when using glycolic acid. This usually fades as your skin adjusts.
Because glycolic acid has the smallest molecular size in the AHA family, it can penetrate deeper, which enhances its effectiveness but also makes it more likely to irritate sensitive skin.
If your skin is very sensitive or prone to rosacea, glycolic acid may be too strong; in that case, try milder options like lactic acid or a PHA instead.
Recent studies suggest glycolic acid might even help protect against UV damage. But don’t skip sunscreen! Freshly exfoliated skin is more sensitive to the sun.
Glycolic acid is a skincare superstar. It smooths, brightens, hydrates, and firms the skin. Unless you’re highly sensitive, it’s well worth adding to your routine.

There are two forms of panthenol: D and L.
D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.
This ingredient is also referred to as pro-vitamin B5.

Apples contain a large amount of antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells.
The sugar in Apples helps keep the skin hydrated. Apples also contain some acids, such as malic acid. These acids may have a mild exfoliating effect.
Apples also contain Vitamins C and B.

This ingredient has often been described as salicylic acid's cousin. This is due to the salicin it contains. However, studies are limited showing salix alba bark to be an effective salicylic acid alternative.
Salicin does have anti-inflammatory and antioxidant properties. It has shown to decrease the formation of inflammatory mediators, such as tumor necrosis factor-α and nuclear factor-kappa B. Salicin also has a mildly exfoliating effect on the skin.
As an astringent, salix alba bark water helps tighten the skin by drawing water out. This helps reduce the appearance of large pores.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
