Clinical Studies Behind Our Skincare Ingredients

Barrier Support Ginseng Cleanser

Gentle cleanser with glycerin and a mild surfactant system. The most directly relevant human evidence supports glycerin as a humectant; clinical evidence for the exact “ginseng stem cell” material in this finished cleanser was not identified.

Relevant published research

• Glycerol moisturizer randomized trial — A placebo-controlled randomized study found a glycerol-containing moisturizer improved measures associated with hydration and barrier function. Study type: randomized, vehicle-controlled.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Tri-Acid Blemish Wash AHA Exfoliating Cleanser

Rinse-off cleanser containing glycolic acid, lactic acid and salicylic acid. Human studies support these acid classes for exfoliation, photoaged appearance and acne-related concerns, but leave-on studies and peels do not prove the performance of this rinse-off formula.

Relevant published research

• Alpha-hydroxy acids on photoaged skin — In a randomized forearm study, lotions containing glycolic, lactic or citric acid produced clinical and histologic changes in photoaged skin versus placebo. Study type: randomized, placebo-controlled.
• Glycolic and salicylic acids in acne-related disorders — A prospective study of a combined glycolic/salicylic acid serum reported improvements in acne, oiliness and texture; the design lacked a placebo control. Study type: prospective, uncontrolled.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Exfoliating Face and Body Cleanser

Rinse-off glycolic- and salicylic-acid cleanser. The studies below support the active ingredient classes; contact time, pH and concentration strongly influence real-world effects.

Relevant published research

• 5% glycolic acid cream and photoaging — A double-blind randomized clinical trial found regular use of an unneutralized 5% glycolic acid cream improved some measures of photoaging. Study type: randomized, double-blind.
• Glycolic and salicylic acids in acne-related disorders — A prospective study of a combined glycolic/salicylic acid serum reported improvements in acne, oiliness and texture; the design lacked a placebo control. Study type: prospective, uncontrolled.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Blemish Pads AHA/BHA Exfoliation Complex

Leave-on pads with glycolic acid, salicylic acid and 1% trichloroacetic acid (TCA). Evidence supports glycolic/salicylic exfoliation. Published TCA evidence often involves professional peels at materially higher strengths, so it should not be used to imply identical results from this product.

Relevant published research

• 5% glycolic acid cream and photoaging — A double-blind randomized clinical trial found regular use of an unneutralized 5% glycolic acid cream improved some measures of photoaging. Study type: randomized, double-blind.
• Glycolic and salicylic acids in acne-related disorders — A prospective study of a combined glycolic/salicylic acid serum reported improvements in acne, oiliness and texture; the design lacked a placebo control. Study type: prospective, uncontrolled.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Blemish Roller Purifying Spot Treatment

Targeted blemish treatment containing benzoyl peroxide and salicylic acid. Benzoyl peroxide has substantial randomized evidence for acne vulgaris; results depend on strength, vehicle, use and tolerance.

Relevant published research

• Benzoyl peroxide gel for acne vulgaris — A 12-week multicenter randomized trial in 609 participants found 2.5% and 5% benzoyl peroxide reduced inflammatory lesion counts more than placebo; adverse events were generally mild or moderate. Study type: phase II/III randomized, double-blind, placebo-controlled.
• Topical benzoyl peroxide for acne — A systematic review concluded benzoyl peroxide alone or as add-on therapy may improve acne more than placebo or no treatment, while noting uncertainty in parts of the evidence base. Study type: systematic review.
• Glycolic and salicylic acids in acne-related disorders — A prospective study of a combined glycolic/salicylic acid serum reported improvements in acne, oiliness and texture; the design lacked a placebo control. Study type: prospective, uncontrolled.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Dual Hyaluronic + B Rehydration Serum

Four-ingredient serum containing hyaluronic acid, sodium hyaluronate and panthenol. Human evidence supports topical HA for hydration and elasticity and panthenol for barrier-supportive hydration.

Relevant published research

• Hyaluronic acid formulations and skin quality — In a clinical study, topical 0.1% hyaluronic acid formulations improved skin hydration and elasticity; lower-molecular-weight HA was also associated with reduced wrinkle depth. Study type: clinical formulation study.
• Dexpanthenol and skin barrier repair — In an experimentally irritated-skin model, dexpanthenol cream accelerated barrier repair and improved hydration and roughness compared with vehicle or untreated skin. Study type: controlled human study.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Ferulic C20 20% L-Ascorbic Acid Serum

Antioxidant serum containing 20% L-ascorbic acid, ferulic acid and vitamin E. Controlled studies support topical vitamin C for visible photodamage. Those trials used different concentrations and vehicles, so they support the ingredient rationale—not a claim that this finished serum produced the same outcomes.

Relevant published research

• Topical ascorbic acid on photoaged skin — A six-month double-blind randomized trial found a 5% vitamin C cream improved clinical and skin-surface measures of photodamage compared with vehicle. Study type: randomized, double-blind, vehicle-controlled.
• Topical vitamin C and facial photodamage — A double-blind half-face study reported improvement in photoaging scores and biopsy evidence consistent with new collagen formation on the vitamin C-treated side. Study type: double-blind, controlled pilot.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Coconut Milk with Hyaluronic Acid Moisturizer

Moisturizer featuring coconut milk, sodium hyaluronate, vitamin E and ellagic acid. The most directly transferable human evidence is for topical hyaluronic acid hydration; evidence for coconut milk in this exact cosmetic use is limited.

Relevant published research

• Hyaluronic acid formulations and skin quality — In a clinical study, topical 0.1% hyaluronic acid formulations improved skin hydration and elasticity; lower-molecular-weight HA was also associated with reduced wrinkle depth. Study type: clinical formulation study.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Daily Collagen + B Moisturizer

Multi-ingredient moisturizer with glycolic acid, hydrolyzed hyaluronic acid, niacinamide and oligopeptide-1. Human evidence supports niacinamide, HA and glycolic acid, while direct clinical evidence for this exact combination was not identified.

Relevant published research

• Topical niacinamide and aging facial skin — A 12-week double-blind, split-face trial of 5% niacinamide reported improvements in fine lines, hyperpigmented spots, texture, red blotchiness and elasticity versus vehicle. Study type: randomized, double-blind, vehicle-controlled.
• Hyaluronic acid formulations and skin quality — In a clinical study, topical 0.1% hyaluronic acid formulations improved skin hydration and elasticity; lower-molecular-weight HA was also associated with reduced wrinkle depth. Study type: clinical formulation study.
• 5% glycolic acid cream and photoaging — A double-blind randomized clinical trial found regular use of an unneutralized 5% glycolic acid cream improved some measures of photoaging. Study type: randomized, double-blind.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Peptide C35 Moisturizer

Multi-active formula containing acetyl hexapeptide-8, palmitoyl tripeptide-1/palmitoyl tetrapeptide-7, a vitamin C derivative, HA and antioxidants. Peptide studies are formulation-specific, so the evidence supports plausibility rather than equivalence to this finished formula.

Relevant published research

• Acetyl hexapeptide-8 anti-wrinkle study — A clinical study reported a significant reduction in facial wrinkle measurements with topical acetyl hexapeptide-8; results apply to the tested formulation and concentration. Study type: clinical study.
• Topical palmitoyl pentapeptide trial — A 12-week randomized split-face trial found a palmitoyl pentapeptide moisturizer improved quantitative measures of fine lines and wrinkles versus the control moisturizer. Study type: randomized, double-blind, placebo-controlled.
• Hyaluronic acid formulations and skin quality — In a clinical study, topical 0.1% hyaluronic acid formulations improved skin hydration and elasticity; lower-molecular-weight HA was also associated with reduced wrinkle depth. Study type: clinical formulation study.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Retinol + K Anti-Aging Eye Cream

Eye-area formula containing all-trans retinol, vitamin K1 and antioxidant ingredients. Randomized human studies support topical retinol for visible fine lines and photoaged appearance. Evidence for vitamin K is more context-specific and should not be used to promise correction of dark circles.

Relevant published research

• Retinol and naturally aged skin — In a randomized vehicle-controlled study, topical retinol improved fine wrinkles in naturally aged skin and increased markers associated with matrix repair. Study type: randomized, vehicle-controlled.
• Retinol and photoaged facial skin — A 26-week randomized study found greater improvement in fine and deep wrinkling on the retinol-treated side than on the vehicle-treated side. Study type: randomized, vehicle-controlled.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Active Restoration Retexturizing Contour Cream

Body treatment with lactic acid, glycolic acid, niacinamide, TCA, arbutin, panthenol and sodium hyaluronate. Evidence supports AHAs, niacinamide and panthenol; arbutin evidence is often from combination regimens, and professional TCA-peel data are not equivalent to this formula.

Relevant published research

• Alpha-hydroxy acids on photoaged skin — In a randomized forearm study, lotions containing glycolic, lactic or citric acid produced clinical and histologic changes in photoaged skin versus placebo. Study type: randomized, placebo-controlled.
• Topical niacinamide and aging facial skin — A 12-week double-blind, split-face trial of 5% niacinamide reported improvements in fine lines, hyperpigmented spots, texture, red blotchiness and elasticity versus vehicle. Study type: randomized, double-blind, vehicle-controlled.
• Dexpanthenol and skin barrier repair — In an experimentally irritated-skin model, dexpanthenol cream accelerated barrier repair and improved hydration and roughness compared with vehicle or untreated skin. Study type: controlled human study.
• Alpha-arbutin regimen for pigmentary spots — A 90-day clinical study of a regimen containing 2% alpha-arbutin plus another brightening ingredient and sunscreen reported reduced melanin and melasma severity; the effect cannot be assigned to arbutin alone. Study type: multi-ingredient clinical regimen.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Clear Mineral SPF 40 Brush On Mineral Powder

Powder sunscreen listing zinc oxide 25% as the active ingredient. FDA’s assessment supports zinc oxide up to 25% under applicable sunscreen requirements, and randomized evidence supports daily sunscreen use in slowing visible photoaging. SPF and broad-spectrum claims must rely on the finished product’s required testing and Drug Facts labeling.

Relevant published research

• FDA sunscreen active-ingredient assessment — FDA states that available evidence supports proposed GRASE status for zinc oxide in sunscreens at concentrations up to 25%, when applicable requirements are met. Study type: regulatory evidence assessment.
• Sunscreen and prevention of skin aging — In a randomized trial, daily sunscreen use was associated with less progression of skin aging over 4.5 years than discretionary use. Study type: randomized controlled trial.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

Evidence note: These sources concern ingredients or other tested formulations. They should not be presented as trials of this Equestra Beauty product.

EB Blemish Control Kit

This regimen bundles blemish-focused products. Use the evidence for benzoyl peroxide and glycolic/salicylic acids while avoiding a claim that the complete Equestra regimen has been clinically tested unless finished-regimen data exist.

Relevant published research

• Benzoyl peroxide gel for acne vulgaris — A 12-week multicenter randomized trial in 609 participants found 2.5% and 5% benzoyl peroxide reduced inflammatory lesion counts more than placebo; adverse events were generally mild or moderate. Study type: phase II/III randomized, double-blind, placebo-controlled.
• Topical benzoyl peroxide for acne — A systematic review concluded benzoyl peroxide alone or as add-on therapy may improve acne more than placebo or no treatment, while noting uncertainty in parts of the evidence base. Study type: systematic review.
