Part of our guide to Skincare Ingredients Explained.
Neither source wins. A plant active can be gentle or irritating, well evidenced or barely studied, and the same is true of a lab made one. What decides whether an ingredient works on your skin is its stability, the concentration it's used at, and whether anyone has tested it properly on human faces. Where it came from tells you almost nothing.
What the two words actually mean
Plant derived means the compound was extracted from a botanical source. Bakuchiol comes from the seeds and leaves of Psoralea corylifolia. Alpha arbutin comes from bearberry. Licorice root, chamomile, green tea extract, cold pressed oils: all plant derived, all wildly different in how they behave on skin.
Synthetic means the molecule was built in a lab. Some synthetics are nature identical, meaning the molecule is chemically the same as the one a plant or your own body makes. Hyaluronic acid is hyaluronic acid whether it was fermented in a tank or extracted from tissue. Your skin cannot tell the difference, because there isn't one.
The word that gets misused is natural. Poison ivy is natural. So is nickel, which is one of the most common contact allergens there is. Natural describes an origin, not a safety profile.
The third category nobody puts on the front of the bottle
Most of the interesting ingredients now sit between the two. Fermentation uses bacteria or yeast to produce a compound, which means you get the exact molecule without harvesting a plant for it.
Squalane is the clearest example. It used to come from shark liver. Now most of it is fermented from sugarcane, which is purer, more consistent, and doesn't involve a shark. The prebiotics and postbiotics in PURIFY are produced the same way. Our piece on what prebiotics and postbiotics do covers why that matters for the barrier.
Call it natural and you're stretching the word. Call it synthetic and you've buried what's good about it.
What actually decides whether an active works
Stability. An active that degrades in the bottle is doing nothing by week three, whatever the label claims. Vitamin C is the standing example: L ascorbic acid oxidises fast in heat and humidity, which describes every bathroom in Singapore. That's why ILLUMINATE uses magnesium ascorbyl phosphate instead, and we've set out the case for the gentler form separately. Bakuchiol, a plant active, happens to be unusually stable. Retinol, a synthetic, is not. The pattern doesn't follow the source.
Concentration you can actually name. This is where whole plant extracts get vague. Rosehip oil contains trace retinoids, so a formula with 10% rosehip oil is not a 10% retinoid product, and nobody selling it will tell you what the actual figure is. A synthetic lets a formulator say 5% niacinamide and mean it. Standardised plant extracts solve the same problem, and cost more.
Evidence on human skin. Far more clinical work exists on synthetics, largely because pharmaceutical money went there first. That gap is closing. Bakuchiol has now been through a randomised double blind trial against retinol, published by Dhaliwal and colleagues in the British Journal of Dermatology in 2019, which found comparable improvement in wrinkling and pigmentation with fewer reports of stinging and peeling.
Whether your skin tolerates it. Essential oils are entirely natural and sit near the top of most contact allergen lists. PURIFY, ILLUMINATE and REJUVENATE contain naturally derived essential oils at low levels. We say so plainly, because natural and gentle are not the same word, and anyone who has reacted to essential oils before deserves to know before they buy rather than after. If your skin has become reactive in the last few years, what causes sensitive skin goes through the usual culprits.
Where plant actives genuinely win
When you need the result without the reaction. Bakuchiol reaches collagen production through a different pathway than retinol, without the peeling and sun sensitivity that make people quietly abandon a retinoid by week five. For anyone over 40 whose skin has become less forgiving, that difference decides whether a product gets used at all. It sits in REJUVENATE for exactly that reason, alongside magnesium, and our side by side comparison covers who should choose which.
The other advantage is complexity. A whole extract carries a range of compounds that developed together rather than one isolated molecule doing one job. Green tea is not just EGCG. Marine extracts carry minerals alongside their polysaccharides, which is why they behave differently from a single isolated hydrator, and we've written about what marine actives do in more detail.
Whether that complexity helps depends on the extract. Sometimes the other compounds are inert passengers.
Where synthetics genuinely win
Precision and consistency. A peptide can be built to signal one specific cellular process. Niacinamide arrives at the same purity in every batch, which matters when the clinical evidence was gathered at 5% and you need the product to contain 5%.
Plant material varies by harvest, soil and season. That variation is charming in wine and unhelpful in a serum you're judging over 12 weeks.
Nature identical synthetics also solve a sourcing problem. Fermented hyaluronic acid is purer than extracted, and no animal or field is involved in making it.
How we actually choose
We pick per function, not per category.
ILLUMINATE pairs alpha arbutin, a plant derived melanin inhibitor from bearberry, with niacinamide and a stabilised vitamin C. Three routes to the same result, and the serum is proven to reduce melanin production by 25%.
REJUVENATE pairs bakuchiol with multi weight hyaluronic acid and magnesium, and reduces cellular aging by 70%. One plant active, one fermented, one mineral.
MERACLE uses red algae, oarweed and deep sea water with a gentle AHA and BHA complex, and increases how much of your next step your skin absorbs by 25%.
SATURATE puts snow mushroom, a plant humectant with molecules smaller than hyaluronic acid, next to hexapeptide 8, a peptide built in a lab to support collagen.
Every one of those is EWG Verified. Byra is the only skincare brand in Singapore that holds it, and the verification applies to the ingredient, not to its origin story. What it doesn't do is tell you whether the formula works, which is a separate question and the one worth asking. We've set out how to judge that in what makes a serum clinical grade.
The three claims to stop believing
Natural is gentler. Essential oils, citrus extracts and some fruit acids say otherwise. Niacinamide and hyaluronic acid, both usually synthetic, are among the best tolerated ingredients in skincare.
Synthetic means harsh chemicals. Synthetic means made in a lab. Water is a chemical. The question is which molecule, at what concentration, in what formula.
Clean beauty is a standard. It isn't. There's no legal definition, which is why the term gets used so freely. What you can check is whether a brand publishes its full ingredient list, holds third party verification, and can point to evidence for its actives. Our guide to checking a clean skincare claim in Singapore shows you how, label claim by label claim.
Questions we get asked
Are plant derived actives more effective than synthetic ones? Not automatically, and any brand claiming otherwise is selling you a story. Some synthetics outperform their plant equivalents on stability and consistency. What plant actives offer is complexity: a single extract carries a range of antioxidants, vitamins and phytonutrients rather than one isolated compound doing one job.
Is synthetic skincare bad for your skin? No. Synthetic is not a safety category. Plenty of synthetics are gentle, well studied and barrier supporting, and plenty of plant ingredients cause irritation. Essential oils are entirely natural and among the more common causes of reactions.
Why do plant derived actives cost more? Extraction is targeted and the raw material is more expensive than synthesising the equivalent molecule. Different parts of a plant concentrate different compounds, so sourcing has to be specific rather than bulk.
What does clean beauty actually mean? Nothing legally. There is no regulated definition, which is why the term gets used loosely. What is checkable is whether a brand publishes its full ingredient list, holds third party verification, and can point to evidence for its actives.
Does skin know the difference between a plant and lab version of the same molecule? For an identical molecule, no. Hyaluronic acid is hyaluronic acid. The difference shows up with whole plant extracts, where you are getting a matrix of compounds rather than one isolated molecule, and that matrix can behave differently from its lead ingredient alone.
Is bakuchiol as good as retinol? For most people over 40 it is the better option, because tolerability decides whether anything gets used long enough to work. A 2019 British Journal of Dermatology trial by Dhaliwal and colleagues found comparable improvement in wrinkling and pigmentation with fewer side effects. If your skin already tolerates retinol, there is no reason to switch.
Where to go from here
Stop sorting your shelf by origin and start asking two questions of each product: what's the active, and at what concentration. Most labels won't answer the second one, and that tells you something in itself.
If you're deciding between a retinoid and a gentler route, the bakuchiol comparison is the place to start.
If you'd rather see the approach across a whole routine, the Complete Skin Transformation Set has all five.
