The Chemistry

Powered by
nature's rarest
fatty acid.

Castor oil's extraordinary efficacy comes from its exceptional molecular composition — a profile unlike virtually any other plant oil on earth. Each drop is a concentrated delivery of compounds that science has proven effective for skin, hair, and overall cellular health.

90%
Primary Fatty Acid · Omega-9
Ricinoleic Acid
The rare omega-9 fatty acid found almost exclusively in castor oil — responsible for its remarkable anti-inflammatory, antimicrobial, and deep-penetrating moisturization. It acts simultaneously as a humectant, an occlusive, and an active anti-inflammatory — a combination no synthetic ingredient replicates.
Vit E
Antioxidant
Tocopherols
Naturally occurring vitamin E protects against oxidative damage and supports collagen synthesis for firmer, more resilient skin.
ω-6
Linoleic Acid
Skin Barrier Support
Reinforces the lipid barrier that keeps moisture locked in and environmental stressors locked out.
ω-9
Oleic Acid
Deep Penetration
Enhances absorption of other beneficial compounds into deeper dermal layers for sustained, lasting results.
pH
Scalp Microbiome
Balance Restoration
Naturally balances scalp pH and suppresses Malassezia fungi — a primary driver of dandruff and hair loss.
What It Does

Six ways castor oil
transforms your ritual.

Backed by centuries of use and validated by modern science — these are castor oil's most significant proven benefits for skin and hair.

Skin Care
Deep Moisturizing
Ricinoleic acid penetrates deeply into the skin's layers, attracting water molecules and locking them in. Its dual humectant-occlusive action provides sustained hydration far beyond what surface-level moisturizers achieve.
Skin Care
Anti-Inflammatory
A clinically proven anti-inflammatory agent. Applied topically, it calms redness, soothes irritated skin, and provides measurable relief for eczema, psoriasis, and post-sun exposure — without steroids.
Skin Care
Antimicrobial
Proven effective against Staphylococcus aureus and Candida albicans — fighting acne and skin infections without disrupting pH or triggering antibiotic resistance.
Hair Care
Promotes Hair Growth
Scalp massage increases follicle circulation while ricinoleic acid may inhibit the enzyme linked to androgenic hair loss. Users report noticeably thicker, longer hair within 4–8 weeks.
Hair Care
Conditions & Strengthens
Omega fatty acids coat the hair shaft, smoothing the cuticle to dramatically reduce frizz and breakage. Regular use fortifies hair, reduces split ends, and adds a visible, natural shine.
Multi-Use
Brow & Lash Serum
Applied nightly with a clean spoolie, castor oil nourishes follicles at the root of each brow and lash — leading to visibly fuller brows and longer, stronger lashes.
Proven by Science

Six things you should know about castor oil.

Castor oil's benefits are not folklore — they are supported by chemistry, clinical research, and thousands of years of documented use across cultures worldwide.

01
Ricinoleic Acid Is Exceptionally Rare
Castor oil contains 85–92% ricinoleic acid — an omega-9 fatty acid found in virtually no other natural source. This compound is directly responsible for most of castor oil's anti-inflammatory, analgesic, and moisturizing capabilities.
02
Deeply Penetrating Viscosity
Castor oil's high molecular viscosity enables it to penetrate deeper into the dermis than most plant oils — reaching layers that surface products cannot, making it more effective for intensive moisturization and follicle nourishment.
03
Dual-Action Humectant
Unlike occlusives that merely seal the surface, ricinoleic acid actively draws water molecules from the environment into the epidermis and retains them there — producing sustained hydration rather than a temporary surface effect.
04
Scalp Health & DHT Inhibition
Research suggests ricinoleic acid may inhibit prostaglandin D2 synthase — an enzyme linked to androgenic hair loss — while simultaneously balancing the scalp microbiome and reducing Malassezia fungi.
05
Collagen & Elastin Stimulation
The fatty acids in castor oil stimulate production of collagen and elastin — proteins responsible for skin firmness and elasticity. Consistent application may reduce fine lines and improve skin texture over time.
06
Clinically Proven Antimicrobial
Peer-reviewed studies confirm castor oil's efficacy against Staphylococcus aureus and Candida albicans — fighting acne-causing bacteria and skin fungi with no antibiotic resistance risk.

Simple steps.
Profound
results.

A few drops of PRESSÈRA go a long way. Castor oil is one of the most concentrated natural oils available — its viscosity means a small amount delivers significant coverage. Consistency is everything.

01
Cleanse First
Begin with clean skin or slightly damp hair. Cleansing removes surface barriers so the oil can penetrate fully. For hair, slightly damp strands absorb oil more evenly than completely dry hair.
02
Warm Between Palms
Dispense 3–5 drops and rub hands together gently. Warming lowers castor oil's natural viscosity, making it easier to apply and dramatically improving absorption into skin and follicles.
03
Apply with Intention
For skin: massage into face, lips, cuticles, or dry patches using upward circular strokes. For scalp: part hair and work directly in with fingertips. For brows and lashes: use a clean spoolie for precise application.
04
Allow Time to Work
For best results, leave on overnight. For scalp treatments, wrap hair in a warm towel for 30 minutes before washing. The longer the contact time, the deeper the penetration and the more profound the benefit.
05
Stay Consistent
Visible hair growth results typically appear after 4–6 weeks of consistent nightly use. Skin softness improvements are often noticed within the first week. Textural improvements develop over 4–8 weeks.

"I've used dozens of hair growth serums and treatments. Nothing came close to three weeks with PRESSÈRA. My brows are fuller, my hair is thicker, and my skin has never felt this hydrated."
