Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Hydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.
In one study, Hydrogenated Polyisobutene showed better skin hydration levels than Caprylic/Capric Triglyceride. As an emollient, it helps keep your skin soft and hydrated by trapping moisture in.
Hydrogenated Polyisobutene is often used as a mineral oil replacement.
Learn more about Hydrogenated PolyisobuteneLactic Acid is another well-loved alpha hydroxy acid (AHA). It is gentler than glycolic acid but still highly effective.
Its main role is to exfoliate the surface of the skin by loosening the âglueâ that holds dead skin cells together. Shedding those old cells leads to smoother, softer, and more even-toned skin.
Because lactic acid molecules are larger than glycolic acid, they donât penetrate as deeply. This means theyâre less likely to sting or irritate, making it a great choice for beginners or those with sensitive skin.
Like glycolic acid, it can:
Lactic acid also acts as a humectant (like hyaluronic acid). It can draw water into the skin to improve hydration and also plays a role in the skin's natural moisturizing factor (NMF) in the form of sodium lactate.
Studies show it can boost ceramide production to strengthen the skin barrier and even help balance the skinâs microbiome.
To get results, choose products with a pH between 3-4.
Lower strengths (5-12%) focus on surface exfoliation; higher strengths (12% and up) can reach deeper in the dermis (deeper, supportive layer) to improve skin texture and firmness over time.
Though it was originally derived from milk, most modern lactic acid used in skincare is vegan. It is made through non-dairy fermentation to create a bio-identical and stable form suitable for all formulations.
When lactic acid shows up near the end of an ingredient list, it usually means the brand added just a tiny amount to adjust the productâs pH.
Legend has it that Cleopatra used to bathe in sour milk to help reduce wrinkles.
Lactic acid is truly a gentle multitasker: it exfoliates, hydrates, strengthens, and brightens. It's a great ingredient for giving your skin a smooth, glowing, and healthy look without the harshness of stronger acids.

Learn more about Lactic AcidPentaerythrityl Tetraethylhexanoate is an emollient that helps make your skin smooth and hydrated. It specializes in creating a non-oily and "wet" feeling on skin.
This ingredient comes from isostearic acid, a saturated fatty acid. It is a synthetic ingredient.
Polybutene is used to help control the viscosity of a product. This just means it helps adjusts the texture.
It is a polymer and does not get absorbed into the skin due to its large size.
Studies found this ingredient did not irritate skin in concentrations below 15%.
Learn more about PolybuteneSorbitan Isostearate is an emulsifer. It is created from isostearic acid and sorbitol.
As an emulsifier, it keeps the water and oil ingredients from separating. This keeps formulas stable and smooth.
In a 24 hour occlusive patch test on 56 subjects, 10% sorbitan isostearate was completely non-irritating. Most formulas use less than 10%.
Because it's a fatty acid ester, it may not be fungal acne safe since the Malassezia yeast can utilize it as a nutrient source.
Learn more about Sorbitan IsostearateTocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.
One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.
Tocopheryl Acetate is commonly found in both skincare and dietary supplements.
Learn more about Tocopheryl AcetateTribehenin comes from glycerin and behenic acid.
It is used as an emollient, or moisturizer. Emollients form a thin barrier on skin to prevent moisture from escaping.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
Learn more about TribeheninVP/Hexadecene Copolymer is a synthetic film-forming agent. It has both water and oil loving properties, allowing it to create a flexible, even film on the skin.
This ingredient helps enhance texture, smoothness, and wear resistance in makeup products while reducing tackiness.
