What Sunday Riley Says
Product Description:
With 1.5 percent salicylic acid, this fast-acting, quick-drying, medicated oil clears acne and blackhead-causing buildup and debris from congested pores for smoother, blemish-free skin. Tea tree oil and black cumin seed oil support clear skin, while hexylresorcinol and licorice naturally brighten the appearance of old acne discolorations.

Key Ingredients
salicylic acid, tea tree oil, black cumin seed oil, hexylresorcinol, licorice
Ingredients Details
Caprylic/capric Triglyceride
Common Name(s): Mct oil,fractionated coconut oil,c8/c10 triglyceride
CAS Number: 73398-61-5
DESCRIPTION
What It Does: Lightweight, stable emollient that solubilizes oil-soluble actives for excellent delivery without greasy feel.
Why It's Used: Universal lightweight emollient base and solubilizer for oil-soluble actives in serums and low-viscosity formulations where mineral oil or petrolatum would be too heavy.
How It Works: Medium-chain length provides ideal balance of spreading coefficient, penetration rate, and barrier-sealing properties. excellent solubilizer for vitamin e, retinoids, and other lipophilic actives.
Typically Found In: Serums,facial oils,sunscreens,anti-aging products,hair products
TECHNICAL DETAILS
Primary Category: Active ingredient โ medium-chain triglyceride emollient
Secondary Functions: Active solubilizer,spreading agent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ50%
SOURCING & ETHICS
Vegan Status: Yes โ from coconut/palm kernel oil
Halal Status: Yes
Source Notes: Fractionated by hydrolysis and re-esterification of coconut oil. only c8 and c10 fatty acids retained.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 1/5 โ very low; medium-chain length generally non-comedogenic
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Mct oil's medium-chain length (c8/c10) provides superior oxidative stability vs longer polyunsaturated chains and better skin aesthetics (lighter, less greasy) vs longer chain emollients (c16/c18). excellent solubilizer for retinoic acid, tocopheryl esters, and other lipophilic actives.

Diisopropyl Sebacate
Common Name(s): Diisopropyl sebacate,cosmetic active,functional ingredient
CAS Number: N/a
DESCRIPTION
What It Does: Delivers characteristic cosmetic function at recommended use concentration.
Why It's Used: Selected for functional contribution and formulation compatibility supported by cosmetic science and regulatory safety data.
How It Works: Works through the mechanism of its molecular class โ physicochemical or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed cosmetic literature.
Typically Found In: Skin care formulations
TECHNICAL DETAILS
Primary Category: Active ingredient โ cosmetic active
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ10%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Diisopropyl sebacate has an established safety and efficacy profile within the cosmetic regulatory framework at standard use concentrations.

Dimethyl Isosorbide
Common Name(s): Dmi,isosorbide dimethyl ether,arlasolve dmi
CAS Number: 5306-85-4
DESCRIPTION
What It Does: Provides biocompatible penetration enhancement for improved active ingredient delivery.
Why It's Used: Biocompatible penetration enhancer from renewable sorbitol โ dmi provides penetration enhancement without the toxicity of oleic acid or conventional chemical penetration enhancers.
How It Works: Cyclic ether from sorbitol is biocompatible and biodegradable. disrupts stratum corneum lipid packing via ether oxygen hydrogen bonding. solubilises challenging actives (retinoids, salicylic acid, ahas). enhances penetration 2โ5ร vs equivalent concentrations without dmi.
Typically Found In: Active delivery formulas,penetration-enhanced products,retinoid vehicles
TECHNICAL DETAILS
Primary Category: Functional ingredient โ penetration-enhancing solvent
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ20%
SOURCING & ETHICS
Vegan Status: Yes โ from sorbitol (corn or wheat derived)
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Dmi's penetration enhancement mechanism differs from oleic acid's lipid disruption: dmi hydrogen bonds to stratum corneum proteins and lipids, temporarily creating more permeable protein-lipid domains without the membrane-fluidisation that causes oleic acid's irritation. this protein-hydrogen-bonding mechanism provides penetration enhancement from a different, gentler pathway.

Glycyrrhiza Glabra (licorice) Root Extract
Common Name(s): Licorice triterpenoid,glycyrrhetinic acid active,anti-inflammatory brightening
CAS Number: N/a
DESCRIPTION
What It Does: Reduces skin inflammation and redness through 11ฮฒ-hsd inhibition (cortisol-amplifying mechanism), inhibits tyrosinase and melanogenesis for brightening, and provides antioxidant protection from the triterpenoid phenol system.
Why It's Used: One of few botanicals with documented cortisone-amplifying anti-inflammatory mechanism โ 11ฮฒ-hsd inhibition elevates local cortisol concentration in skin tissue, providing a pharmaceutical-level anti-inflammatory effect without direct corticosteroid application.
How It Works: Glycyrrhetinic acid inhibits 11ฮฒ-hydroxysteroid dehydrogenase (11ฮฒ-hsd) โ the enzyme that converts active cortisol to inactive cortisone in peripheral tissues. inhibition elevates local skin cortisol, amplifying the glucocorticoid anti-inflammatory response. simultaneously, glabridin (a flavonoid in licorice) inhibits tyrosinase for brightening.
Typically Found In: Anti-inflammatory,soothing,brightening
TECHNICAL DETAILS
Primary Category: Active ingredient โ antioxidant
Secondary Functions: Free radical scavenging,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01%โ2%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; well-tolerated.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Vitamin c,vitamin e,ferulic acid,spf,other antioxidants
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
11ฮฒ-hsd inhibition by glycyrrhetinic acid was first documented in the context of licorice consumption causing pseudoaldosteronism โ the same enzyme inhibition applied topically provides localised cortisol amplification for cosmetic anti-inflammatory activity without systemic effects.
