Introducing Foundation with Peptides - The B's Botanicals Foundation Line.
This is not how most foundations begin. Most begin with pigment. Ours began with a question.
What would a foundation look like if it was formulated the way a skincare product is?
Not designed to sit on the skin, but to work with it. Not built to hide the complexion, but to refine it, while genuinely supporting the skin’s health with every wear.
That question is the origin of the B’s Botanicals Foundation with Peptides.
A COSMOS NATURAL certified foundation range designed at the precise intersection of modern cosmetic science, botanical formulation and real inclusivity, across 10 shades, from fair to deep, across neutral, warm and cool undertones.
Why we created it?
The foundation category is one of the most scientifically complex in cosmetics, and one of the most historically underserved for two reasons.
First: the dominant formulation model has prioritised coverage over skin compatibility, producing products that feel heavy, look artificial and dehydrate with wear.
Second: shade ranges have routinely failed to represent the full spectrum of human complexion, particularly for medium-to-deep undertones. where poorly matched pigment blends result in foundations that pull orange, sit ashy or fail to honour the undertone dimension of the skin.
We built Foundation with Peptides to address both failures simultaneously.
The formula is built around a core of clinically and scientifically documented actives a peptide, a dual hyaluronic acid system, botanical antioxidants and skin-compatible humectants housed in a lightweight, self-setting base with a velvety semi-matte finish.
The shade range was developed with undertone precision at its centre: 10 shades covering fair, light, medium, tan and deep complexions, each calibrated to either a neutral, warm or cool undertone profile.
The result is a foundation that performs cosmetically and behaves scientifically — coverage that respects the skin, rather than covering it up.
The science behind the formula.
Every ingredient in Foundation with Peptides has been selected with intention. The formulation rationale is grounded in published scientific and clinical literature. Here is what the evidence shows.
Hexapeptide-11 - The Peptide at the Heart of the Range.
Hexapeptide-11 is a synthetic hexapeptide a chain of six amino acids developed for use in cosmetic formulations targeting complexion refinement and surface quality.
Peptides applied topically function as biological communication molecules: they interact with epidermal receptors and influence the biochemical processes that govern skin texture, firmness and renewal.
Gorouhi & Maibach (2009), in a comprehensive review published in the International Journal of Cosmetic Science, documented the mechanism by which synthetic peptides applied topically can modulate collagen synthesis and support visible surface refinement noting measurable improvements in skin texture and smoothness following regular application.
A further review by Ledwoń et al. (2021) in Cosmetics confirmed that short-chain peptides, including hexapeptides, are well tolerated by all skin types, including sensitive skin and exert their effects at the epidermal level without penetrating to deeper systemic tissues.
Dual Hyaluronic Acid System - Hydrolyzed Hyaluronic Acid + Sodium Hyaluronate.
Hyaluronic acid (HA) is one of the most extensively studied molecules in dermatological science a naturally occurring glycosaminoglycan capable of binding up to 1,000 times its own molecular weight in water (Papakonstantinou et al., 2012, Dermato-Endocrinology).
This formula uses two molecular weight forms deliberately:
Hydrolyzed Hyaluronic Acid (low molecular weight) to penetrate the uppermost skin layers, and Sodium Hyaluronate (medium-to-high molecular weight) to form a surface film that locks in moisture throughout wear.
A randomised controlled study by Jegasothy et al. (2014) in the Journal of Clinical and Aesthetic Dermatology demonstrated statistically significant improvements in skin hydration after 8 weeks of topical HA application.
Aloe Barbadensis Leaf Juice - Organic Botanical Conditioning
Aloe vera contains over 75 identified bioactive compounds including polysaccharides, vitamins C and E, proteolytic enzymes and amino acids. Surjushe et al. (2008) in the Indian Journal of Dermatology documented its clinically demonstrated moisturising, anti-inflammatory and barrier-supporting properties.
Dal’Belo et al. (2006) in the Journal of Dermatological Treatment confirmed significant improvements in skin moisture content and elasticity within 30 days of topical application.
In this formula, aloe vera from certified organic farming forms the conditioning base, creating a smooth, comfortable canvas throughout wear.
Glycerin + Sodium PCA - Humectant Moisture Anchors.
Glycerin is one of the most clinically validated humectants in cosmetic chemistry. Fluhr et al. (2008) in the British Journal of Dermatology confirmed its role in reducing transepidermal water loss (TEWL), improving skin elasticity and modulating aquaporin function to facilitate moisture movement within the skin.
Sodium PCA is a naturally occurring component of the skin’s own Natural Moisturising Factor (NMF).
Research by Rawlings & Harding (2004) in Dermatologic Therapy established that topical NMF components significantly support corneocyte hydration and improve the tactile feel of the skin surface.
Blueberry Extract - Antioxidant Botanical Protection.
Blueberry fruit extract is exceptionally rich in anthocyanins polyphenolic flavonoids with among the highest documented antioxidant capacity of any botanical source. Prior et al. (1998) in the Journal of Agricultural and Food Chemistry established blueberry as a top-ranked antioxidant by ORAC measurement.
In a formula worn during daylight hours, antioxidant botanicals provide ongoing environmental defence against oxidative damage from UV exposure, pollution and blue light.
Peony Root Extract - Botanical Anti-Inflammatory Refinement.
Peony root extract contains paeoniflorin as its primary bioactive glycoside. Luo et al. (2022) in Phytomedicine summarised how paeoniflorin modulates inflammatory signalling pathways through inhibition of NF-κB activation making it a clinically relevant inclusion for sensitive or reactive skin types.
Kaolin, Silica & Rice Starch - The Finish System.
Kaolin absorbs excess sebum without compromising the moisture barrier (Draelos, 2006, Journal of Cosmetic Dermatology). Silica diffracts and scatters light at the skin’s surface, visually blurring texture and pores (Voegeli, 2007, Cosmetics & Toiletries).
Rice Starch adds a silky, skin-soft texture. Together they create the velvety semi-matte signature: not flat, not shiny, luminously refined.
Tocopherol - Vitamin E Antioxidant Integrity.
Thiele et al. (2005) in the American Journal of Clinical Nutrition documented tocopherol’s role in protecting cell membrane lipids from peroxidation and supporting the skin barrier.
Within the formula it contributes antioxidant stability and skin-conditioning properties across the full botanical system.
Pure Mineral Pigments - Shade Precision Across 10 Complexions.
The colour system is built entirely from iron oxides (CI 77491, CI 77492, CI 77499) and titanium dioxide (CI 77891). Chemically inert, non-irritating and with a long safety record in cosmetic dermatology, mineral pigments enable smooth, buildable coverage without caking or oxidising.
The pigment ratios for each of the 10 shades are calibrated specifically for their undertone profile not just their depth which is what makes each shade look like skin, rather than sitting over it.
10 Shades. Every Undertone. Every Complexion.
Finding the right foundation is not just about depth it is about undertone.
The warm, cool or neutral dimension running beneath your skin’s surface is what determines whether a foundation looks seamless or sits visibly wrong. Foundation with Peptides was built with that precision from the start.
The full Foundation with Peptides shade range - 05 to 50, fair to deep.
🤍 Light Shades - 05 · 10 · 15
05 Fair Neutral
The lightest shade in the range. A soft, cool-neutral beige for very fair complexions where neither pink nor yellow dominates. Calibrated to read as balanced, authentic skin in natural light without the yellow cast that pulls warm, or the pink that reads artificial.
10 Light Warm
A warm-leaning light shade with golden or peachy undertones. Built for light complexions where a natural warmth runs just beneath the surface complementing that warmth rather than neutralising it.
15 Light Cool
A cool-toned light shade for fair-to-light complexions with pink or blue undertones. One of the most underserved light shades in the market formulated to avoid the orange pull that poorly matched foundations produce on cool light skin.
🤍 Medium Shades - 20 · 25
20 Medium Neutral
A balanced, versatile medium shade for complexions that sit centrally on the undertone spectrum neither definitively warm nor cool. Calibrated to read as undistorted, authentic skin in all lighting conditions.
25 Medium Warm
A richly warm medium shade for golden and olive complexions Mediterranean, South Asian and mixed-heritage skin carrying a natural luminous warmth. Formulated to honour that dimension, not subdue it.
🤍 Tan Shades - 30 · 35
30 Tan Neutral
A versatile tan shade spanning a broader neutral range. Well suited to complexions that shift seasonally or read differently across light conditions a shade designed to adapt rather than restrict.
35 Tan Warm
A warm-toned tan for deeper tan and light-brown complexions with clearly golden undertones. Built to deliver richness and warmth without the orange cast that compromises so many foundations at this depth.
🤍 Deep Shades - 40 · 45 · 50
40 Deep Neutral
A rich, balanced deep brown for deep complexions with neutral undertones. No warmth pull. No ashy drift. A shade calibrated to sit as seamlessly on deep neutral skin as the lightest neutrals sit on fairer complexions.
45 Deep Warm
A warm, golden deep brown for complexions with a rich warmth beneath the surface. Formulated to celebrate the golden depth of dark complexions rather than correct it.
50 Deep Cool
A cool, blue-neutral deep brown for deep complexions with a grey-blue undertone dimension. One of the most precisely calibrated shades in the range for a complexion that has historically been underserved by the beauty industry, and that deserves a foundation that truly sees it.

Frequently Asked Questions.
What makes Foundation with Peptides different from other natural foundations?
Most natural foundations compromise on either performance or skin compatibility. Foundation with Peptides is built around a COSMOS NATURAL certified formula that combines Hexapeptide-11, a dual hyaluronic acid system and botanical antioxidants delivering a velvety semi-matte finish with genuine skincare-grade actives. It does not feel heavy, does not dehydrate with wear, and does not mask the skin’s natural dimension.
What does COSMOS NATURAL certified mean?
COSMOS NATURAL is an internationally recognised third-party certification standard that verifies a cosmetic product’s natural and organic credentials. It requires a minimum percentage of natural-origin ingredients, prohibits certain synthetic ingredients, and mandates transparent traceability of raw materials. Foundation with Peptides is 99% ingredients of natural origin and meets the full COSMOS NATURAL standard.
Is Foundation with Peptides suitable for sensitive skin?
Yes. The formula is dermatologically tested and suitable for all skin types, including sensitive skin. It is free from sulphates, silicones and artificial fragrance three of the most common sensitising agents in conventional foundation formulas. Peony root extract and aloe vera provide additional anti-inflammatory and soothing support within the formula. As with any cosmetic product, a patch test is recommended if your skin is particularly reactive.
How do I choose the right shade?
Start with your depth (fair, light, medium, tan or deep), then determine your undertone. Hold your wrist under natural light: if your veins appear blue or purple, you lean cool; if they appear green, you lean warm; if you see both, you are likely neutral. Each shade description above is written to help you identify your match. If in doubt, browse the full shade range and reach out we are happy to help.
Is Foundation with Peptides full coverage?
It provides buildable coverage from a skin-like, natural everyday finish with one layer, to a more refined and perfected complexion when built up selectively.
