Botanicals are plant-derived actives, and they range from genuinely well-studied (centella, green tea, licorice) to mostly marketing. The category is where hype concentrates, so it is also where honest evidence-flagging matters most. Many are excellent soothing antioxidants; few are the miracle their packaging implies.
The strongest botanicals tend to be anti-inflammatory antioxidants. Centella asiatica supports barrier repair and calming; green tea (EGCG) is a well-studied antioxidant; licorice root helps fade pigment. Newer soothing actives like ectoin, beta-glucan and heartleaf have growing support for sensitive skin.
This group also includes microbiome ingredients — pre-, pro- and postbiotics, and ferment filtrates like galactomyces — an active research area where enthusiasm currently outpaces hard clinical proof. We include them because they are legitimate and interesting, while being clear that "emerging" means the jury is still out.
Every botanical we cover, with what it does and the concerns it is most often used for. Each name links to its full glossary entry.
| Ingredient | What it is | Most used for |
|---|---|---|
| Centella Asiatica | One of the most clinically validated plant-based actives. | Redness, Aging |
| Green Tea Extract | Rich in catechins, primarily EGCG — a potent free-radical scavenger, anti-inflammatory, and mild androgen receptor inhibitor relevant to sebum reduction. | Aging, Acne, Oiliness |
| Resveratrol | A polyphenol from grape skin, red wine and blueberries. | Aging, Redness |
| Licorice Root Extract | A well-studied plant-derived brightener. | Pigmentation, Redness, Dullness |
| Rosehip Seed Oil | Cold-pressed oil rich in linoleic acid (36–45%), alpha-linolenic acid (19–30%) and naturally occurring trace retinoic acid. | Aging, Pigmentation, Dryness |
| Aloe Vera | Contains polysaccharides, glycoproteins, aloesin, anthraquinones and minerals with proven wound-healing, anti-inflammatory, moisturising and mild brightening properties. | Redness, Dryness, Pigmentation |
| Neem Extract | Ayurvedic botanical with potent antibacterial, antifungal and anti-inflammatory properties. | Acne, Oiliness, Redness |
| Turmeric Extract | Curcumin is a potent anti-inflammatory, antioxidant and tyrosinase-inhibiting brightener. | Redness, Pigmentation, Acne |
| Ectoin | A natural extremolyte produced by extremophilic bacteria to protect cellular structures from environmental stress. | Redness, Aging, Dryness |
| Colloidal Oatmeal | FDA-approved as an OTC skin protectant. | Redness, Dryness |
| Sulforaphane | An isothiocyanate from cruciferous vegetables — one of the most potent activators of NRF2, the master regulator of the body's own antioxidant enzyme system. | Aging, Redness |
| Beta-Glucan | A polysaccharide drawn from oats, barley, yeast, mushrooms or algae. | Dryness, Redness, Aging |
| Galactomyces Ferment Filtrate | The filtered liquid left after culturing the yeast Galactomyces — the fermentation active popularised by Japanese essences. | Dullness, Texture, Pigmentation |
| Heartleaf Extract | An extract of Houttuynia cordata, a herb long used in East Asian medicine and now a staple of Korean "cica-adjacent" soothing products. | Redness, Acne |
| Postbiotics | The beneficial by-products of microbial fermentation — and the inactivated microbes themselves — used to support the skin's microbiome without the instability of live bacteria. | Redness, Dryness |
| Prebiotics | Non-living ingredients — typically sugars, oligosaccharides and polyols — that act as selective food for the beneficial microbes on your skin, helping a balanced microbiome flourish. | Redness, Dryness |
Across the catalogue, the botanicals here are most often used for these concerns — each links to its evidence-led concern hub with a full routine:
Redness (13), Aging (7), Dryness (7), Pigmentation (5), Acne (4), Oiliness (2), Dullness (2), Texture (1).
These commonly pair well with: Niacinamide, Centella Asiatica, Hyaluronic Acid, Vitamin C, Panthenol, Ceramides. Pairing is about getting more from a routine without adding irritation — humectants, barrier lipids and niacinamide are frequent partners here.
Nothing in this category carries a hard "avoid combining" flag in our catalogue — these are generally cooperative actives. Always introduce one new product at a time regardless.
Not inherently. "Natural" is a marketing term, not a measure of safety or efficacy — some botanicals are potent and well-evidenced, others do little, and a few are common irritants (essential oils, for instance). What matters is the specific ingredient and the evidence behind it, not whether it came from a plant.
Centella asiatica and green tea (EGCG) are among the best-supported for soothing and antioxidant benefits, and licorice root has reasonable evidence for brightening. These have real clinical backing, whereas many trendier extracts are supported mainly by lab or in-vitro data rather than results on actual skin.
It is a genuinely promising but still-emerging area. There is early evidence that supporting the skin microbiome can help barrier function and calm reactive skin, but the clinical proof is thinner than the marketing suggests. Reasonable to try for sensitivity; too soon to treat as established.
Often, but not always. Soothing botanicals like centella, oat and beta-glucan are excellent for sensitivity, while fragrant plant extracts and essential oils are among the more common triggers. Read for the specific extract, patch test, and be wary of products that lean on "botanical" as a selling point without naming what is doing the work.
