What is COSMOS certification?
COSMOS (Cosmetic Organic and Natural Standard) is an internationally recognized label that guarantees a product’s natural and organic integrity. According to Ecocert’s COSMOS certification page, a product must contain at least 95% plant‑derived ingredients, with a minimum of 20% organic content for rinse‑off items (10% for leave‑on). The label also bans petro‑chemical preservatives (except a short, approved list), GMO ingredients, and mandates recyclable packaging.

Why does this matter? Because COSMOS blends the rigor of organic farming with the transparency of clean‑beauty standards, giving eco‑conscious consumers a trustworthy shortcut.
Some wonder if COSMOS is just a marketing buzzword. The answer? No. The certification involves full ingredient traceability, production audits, and third‑party testing, ensuring the claims are not empty.
Why choose an organic cleanser?
Organic cleansers avoid synthetic surfactants that can disrupt the skin’s microbiome. Instead, they rely on plant‑based surfactants like disodium cocoyl glutamate and lauryl glucoside, which gently lift dirt while preserving moisture.
One Love Organics’ Botanical A Facial Cleanser exemplifies this approach, combining mild plant‑powered cleansers with lactic acid and salicylic acid for a dual‑action foam that “purifies the skin while diminishing the appearance of fine lines and wrinkles”【1】. Users report a “luxurious, cushiony lather” and no tightness after rinsing.
For people with psoriasis or extremely sensitive skin, the National Psoriasis Foundation’s Seal of Recognition highlights products that are non‑irritating and safe【2】. While not every COSMOS product carries this seal, the rigorous testing overlaps significantly, giving extra confidence.
Bolded tip: Pair any organic cleanser with a mineral SPF 30+ to protect the fresh skin cells after gentle exfoliation.
Some might think “organic = less effective.” In reality, the right actives (like AHA/BHA) can be derived from organic sources, delivering the same performance without harsh chemicals.
Some are concerned about price. While COSMOS‑certified items often cost more than mass‑market alternatives, the long‑term benefits—reduced irritation, fewer breakouts, and sustainable sourcing—provide excellent value.
Some wonder if the packaging is truly eco‑friendly. COSMOS requires recyclable or refillable packaging, and many brands (including LULUMINE) use glass or post‑consumer recycled plastic.
Key criteria for the best COSMOS certified organic cleanser
When scouting for the best COSMOS certified organic cleanser, keep these six checkpoints in mind:
- Organic ingredient percentage: Look for ≥95% natural origin and ≥20% organic content for rinse‑off products.
- Surfactant type: Prefer plant‑based surfactants (disodium cocoyl glutamate, lauryl glucoside) over sulfates.
- Active ingredients: AHA (lactic acid) and BHA (salicylic acid) derived from natural sources add exfoliation power.
- Skin‑type suitability: Verify the formula is dermatologist‑tested for sensitive or reactive skin.
- Packaging sustainability: Recyclable, refillable, or biodegradable containers.
- Certifications & seals: COSMOS + any additional seals (e.g., NPF Seal of Recognition).
Cross‑checking these criteria ensures you pick a cleanser that truly lives up to its “organic” promise.
Some ask, “Do I need a cleanser with AHA if I already use a serum?” The answer depends on your skin goals; a gentle AHA cleanser can boost serum absorption by removing dead cells.
Some worry about irritation from acids. Remember that COSMOS‑certified formulas often balance acids with soothing agents like aloe vera leaf juice, as seen in the One Love Organics product.
Ingredient spotlight: AHA, BHA, and plant surfactants
Lactic acid, an alpha‑hydroxy acid (AHA), gently exfoliates while boosting moisture. In the Botanical A Facial Cleanser, lactic acid “helps improve the look of aging skin, including fine lines, while also enhancing the skin’s natural moisture factor”【1】. Because it’s derived from fermented plant sugars, it aligns with COSMOS organic standards.
Salicylic acid, a beta‑hydroxy acid (BHA), penetrates oil‑filled pores to clear congestion. The same cleanser includes salicylic acid for “alleviate clogged pores and blackheads”【1】. When sourced from willow bark or wintergreen (both plant‑based), it meets organic criteria.
Plant‑based surfactants such as disodium cocoyl glutamate and lauryl glucoside are derived from coconut or corn sugars. They create a “luxurious, cushiony lather” without stripping the lipid barrier.
Other supportive ingredients include:
- Aloe barbadensis leaf juice*: Soothes and hydrates.
- Wintergreen extract*: Provides natural menthol freshness.
- Moringa seed oil: Offers antioxidant protection.
*Ingredients marked with an asterisk come from organic farming, a key COSMOS requirement.
Some wonder if these ingredients can cause allergic reactions. Because they are plant‑derived and minimally processed, the irritancy score is often zero, as confirmed by One Love Organics’ “gold standard irritancy score of zero” claim.
Some ask how to store a cleanser with live botanical extracts. Keep it in a cool, dark place and close the lid tightly; most COSMOS‑certified formulas are formulated for stability over 12‑24 months.
How to choose the right cleanser for your skin type
Choosing the perfect cleanser is a personal journey. Below is a quick decision‑tree you can follow:
| Skin Concern | Best Ingredient(s) | Suggested COSMOS Cleanser Feature |
|---|---|---|
| Dry or Sensitive | Aloe vera, glycerin, low‑pH surfactants | Fragrance‑free, soothing actives, no BHA |
| Oily or Acne‑prone | Salicylic acid, tea tree oil, niacinamide | Contains BHA, non‑comedogenic, oil‑absorbing powders (e.g., calcium silicate from Micropowders) |
| Uneven tone / Fine lines | Lactic acid, vitamin E, antioxidant botanicals | AHA‑rich, antioxidant blend, anti‑aging peptides |
| Combination | Balanced surfactants + spot‑treating actives | Dual‑phase formula or two‑step routine |
For oily skin, the Micropowders database lists “ultrafine hybrid powder… for oil absorption”【4】. Including such powders in a cleanser can reduce shine without harsh astringents.
Some may wonder whether a cleanser can replace a toner. While a well‑formulated COSMOS cleanser can balance pH, a separate toner can add extra hydration or targeted actives.
Some ask if they should double‑cleanse. If you wear makeup or sunscreen, start with an oil‑based cleanser (like LULUMINE’s Botanical B Enzyme Cleansing Oil) then follow with a COSMOS‑certified gel cleanser for a thorough yet gentle cleanse.

Some ask if LULUMINE’s cleanser is suitable for acne‑prone skin. The inclusion of salicylic acid and oil‑absorbing hemp seed oil makes it a strong candidate, though those with extremely oily skin may prefer an additional mattifying toner.

Side‑by‑side comparison of top picks
| Product | Organic % | Key Actives | Suitable Skin Types | Price (GBP) |
|---|---|---|---|---|
| LULUMINE Organic Hemp Glow Cleanser | 91% | Lactic acid, Salicylic acid, Hemp seed oil | All, especially combination | £22 |
| One Love Organics Botanical A Facial Cleanser | 53% (99% natural origin) | Lactic acid, Salicylic acid, Aloe vera | Normal to oily, not ultra‑sensitive | £28 |

When comparing, note that LULUMINE’s formula offers the highest organic percentage while still delivering a balanced blend of AHA and BHA. One Love Organics shines with a higher natural origin score but contains fewer organic ingredients overall.
Some wonder which is the “best.” The answer hinges on your priority: highest organic content (LULUMINE), strongest actives (One Love), or budget‑friendly sustainability (Eco‑Certified Green).
Some readers ask if a cleanser can replace a serum. The short answer: not completely. Cleansers prep the skin; serums deliver concentrated actives post‑cleansing.
