Dimethicone is a silicone-based ingredient that forms a smooth, protective layer on your skin. It helps lock in moisture, creates a soft feel, and is commonly used in moisturizers and primers to improve product texture and skin hydration.
Benefits
Improves skin hydration by creating a moisture-barrier layer
Provides a smooth, silky feel to products and on skin
Well-tolerated by sensitive and atopic (eczema-prone) skin
Non-greasy alternative to heavier oils
Science: Clinical studies demonstrate dimethicone is safe and well-tolerated in children with atopic dermatitis from 12 months of age. Research shows moisturizers containing dimethicone effectively improve skin hydration in mild-to-moderate atopic dermatitis patients over 14 days.
Glycerin is a naturally derived humectant—a ingredient that draws moisture from the air into your skin. It's one of the most widely used and well-studied moisturizing agents in skincare, helping skin feel softer and more hydrated.
Benefits
Attracts and retains moisture in the skin
Improves skin hydration and softness
Helps strengthen skin barrier function
Suitable for most skin types, including sensitive skin
Science: The Cosmetic Ingredient Review Expert Panel concluded glycerin is safe as used in cosmetics across all concentrations. Research shows glycerin effectively improves skin hydration and is well-tolerated with minimal irritation risk. It is also referenced in clinical guidelines for managing inflammatory skin conditions and maintaining skin integrity.
Trehalose is a naturally occurring sugar (disaccharide) used in skincare products for its stabilizing and protective properties. It helps preserve the integrity of skin cells and other ingredients, particularly when exposed to environmental stressors like heat or dryness.
Benefits
Helps stabilize and protect skin cells from damage
May improve skin barrier function and reduce moisture loss
Supports ingredient stability in formulations
Science: Trehalose is widely recognized in biopharmaceutical and cosmetic industries for its cryoprotective and stabilizing properties. While peer-reviewed evidence specifically for topical skincare benefits is limited, research demonstrates its effectiveness as a cellular protectant and its ability to enhance the uptake and efficacy of other beneficial compounds in tissues.
Sodium benzoate is a preservative used in skincare products to prevent bacterial and fungal growth, extending shelf life. It's a salt derived from benzoic acid and is one of the most widely used preservatives in cosmetics, skincare, and food products.
Benefits
Prevents microbial contamination and extends product shelf life
Generally effective at low concentrations (0.1-0.5%)
Approved for cosmetic use by major regulatory bodies
Potential concerns
Can cause allergic contact dermatitis in sensitive individuals; identified as an allergen in medical hand cleansers
Recent research suggests long-term oral intake may affect bone health and increase osteoporosis risk, though topical skincare exposure is minimal
Science: Sodium benzoate is well-established as a safe preservative in cosmetics at typical use levels. However, emerging research indicates that chronic systemic intake may interfere with bone metabolism through the FGF2/p38/RUNX2 pathway. For topical skincare use, the exposure and absorption are minimal compared to dietary intake, but individuals with known sensitivities should avoid it.
Sodium lactate is a salt derived from lactic acid that acts as a humectant and pH buffer in skincare products. It helps draw moisture into the skin and maintain the product's stability.
Benefits
Humectant that attracts and retains water in the skin
Helps maintain skin hydration and plumpness
Gentle pH buffer that stabilizes formulations
Science: Limited peer-reviewed data available specifically for topical skincare use. The provided research focuses on medical applications (intravenous use in shock treatment) and cellular mechanisms unrelated to cosmetic skincare; these do not directly inform safety or efficacy for topical skin application.
Lactic acid is a mild chemical exfoliant that works by gently dissolving the bonds between dead skin cells on the surface, helping to slough them away. It's an alpha hydroxy acid (AHA) derived from milk fermentation and is gentler than stronger exfoliants, making it suitable for sensitive skin types.
Benefits
Gently exfoliates dead skin cells for a smoother texture
Improves skin radiance and brightness
Helps reduce the appearance of fine lines and uneven skin tone
Supports skin hydration by improving moisture absorption
Potential concerns
Can cause redness, stinging, or irritation, especially at higher concentrations or on sensitive skin
Increases sun sensitivity — daily SPF is essential when using
May irritate active acne or compromised skin barrier
Can cause dryness if overused or not followed with adequate moisturizer
Science: Lactic acid is widely recognized as an effective gentle exfoliant for improving skin texture and hydration. It has a longer history of safe topical use in dermatology compared to stronger AHAs, though it requires proper formulation (typically 5-12% for leave-on products) and concurrent sun protection to minimize irritation risk.
Niacinamide is an active form of vitamin B3 that works within your skin's cells to strengthen the barrier, reduce inflammation, and regulate oil production. It's a water-soluble ingredient that's been shown to have multiple benefits across different skin concerns, from sensitivity to aging.
Benefits
Reduces redness and calms irritation
Minimizes pore appearance and controls excess oil
Supports skin barrier function and hydration
Brightens skin tone and evens complexion
Has anti-aging properties and protects against environmental damage
Science: Niacinamide is well-tolerated and safe across diverse skin types with strong clinical evidence supporting its use for acne, dermatitis, and general skin health. Research shows it works by regulating inflammation at the cellular level and protecting skin barrier integrity, with proven efficacy in concentrations commonly found in cosmetic products.
Titanium dioxide is a mineral powder that sits on top of your skin to physically block both UVA and UVB rays from the sun. It's one of the most commonly used active ingredients in mineral (physical) sunscreens and is also used in tinted formulations to provide visible light protection.
Benefits
Provides broad-spectrum UV protection (UVA and UVB)
Physical blocker that doesn't require absorption into the skin
Generally well-tolerated and suitable for sensitive skin
Offers additional visible light protection when used in tinted formulations, which may benefit those with melasma or other pigmentation concerns
Potential concerns
Can leave a white or chalky cast on skin, though nanoparticle formulations minimize this
May feel heavy or occlusive for some users
Science: Titanium dioxide is a well-established, inorganic UV filter with a strong safety profile. Unlike organic sunscreen filters, it is not systemically absorbed and does not pose the environmental concerns (such as coral bleaching) associated with chemical filters. Recent research confirms its effectiveness in both standard and visible light protection applications.
Polyacrylate Crosspolymer-6 is a synthetic polymer used as a thickener and stabilizer in skincare formulas. It helps create a smooth, gel-like texture and keeps product ingredients evenly distributed without separating.
Benefits
Creates smooth, spreadable texture
Stabilizes formulas and prevents separation
Helps products feel lightweight on skin
Science: Limited peer-reviewed data available for this ingredient. As a synthetic polymer, it is generally recognized as safe for topical use and is not absorbed through the skin due to its large molecular size. It is approved for cosmetic use in major regulatory regions.
