Barrier Support & Hydration
Hyaluronic Acid and Tremella Fuciformis Extract deliver deep hydration, while Ectoin and Pro-Xylane support skin barrier repair and resilience.
Safety & compatibility
SAFEContains Tranexamic Acid and Alpha-Arbutin. While topical use is generally low-risk, consult your healthcare provider before use during pregnancy or breastfeeding.
Free of ferments, fatty acids, esters, and polysorbates. No ingredients known to feed the malassezia yeast that causes fungal acne.
Oil-free, silicone-free formula with a comedogenic rating of 1/5. Extremely unlikely to clog pores or cause breakouts.
The 15% L-Ascorbic Acid concentration at a low pH (2.5–3.5) may cause mild tingling on very sensitive or compromised skin. Patch test recommended before first use.

Vitamin C provides antioxidant photoprotection but does not replace SPF. Always apply broad-spectrum sunscreen (SPF 30+) after this serum during daytime use.
Ingredient breakdown
INGREDIENTSL-Ascorbic Acid (Vitamin C) 15%Proven
The gold-standard form of Vitamin C. A pure, potent antioxidant that brightens skin, stimulates collagen synthesis, and provides photoprotection. Most effective at concentrations between 10–20% and a pH below 3.5.
- Research: Pinnell et al. (2001) demonstrated that 15% L-Ascorbic Acid at pH 3.5 provides optimal skin penetration and efficacy.
- Benefit: Reduces appearance of fine lines, hyperpigmentation, and sun damage while boosting collagen production.
- Synergy: Combined with Vitamin E and Ferulic Acid, photoprotective capacity doubles (Lin et al., 2005).
Ferulic Acid 0.5%Proven
A plant-derived antioxidant naturally found in rice, wheat, and oats. Stabilizes Vitamins C and E and enhances their photoprotective effects. Also provides independent UV protection benefits.
- Research: Lin et al. (2005) showed that adding 0.5% Ferulic Acid to a 15% C + 1% E formula doubles sun protection and improves stability.
- Benefit: Fights free radical damage, reduces inflammation, and helps prevent UV-induced skin aging.
Tocopherol (Vitamin E) 1%Proven
A lipid-soluble antioxidant that protects cell membranes from oxidative damage. Works synergistically with Vitamin C — each regenerates the other, creating a continuous cycle of antioxidant defense.
- Research: 1% alpha-tocopherol is the clinically validated concentration in the C+E+Ferulic trio.
- Benefit: Moisturizes, soothes inflammation, and enhances the UV-protective capacity of Vitamin C.
Tranexamic AcidProven
A synthetic amino acid derivative clinically shown to inhibit melanin production and reduce hyperpigmentation. Particularly effective against melasma and post-inflammatory dark spots.
- Research: Multiple studies confirm topical Tranexamic Acid reduces melanin synthesis by inhibiting plasminogen activation in keratinocytes.
- Benefit: Fades dark spots, evens skin tone, and reduces UV-triggered inflammation.
Niacinamide (Vitamin B3)Proven
A multi-functional superstar that strengthens the skin barrier, reduces pore appearance, controls oil production, and fades hyperpigmentation. Works well with Vitamin C at the formula's low pH.
- Research: Shown to increase ceramide synthesis, improve skin barrier function, and reduce melanin transfer to skin cells.
- Benefit: Smooths texture, evens tone, and helps manage oiliness and enlarged pores.
EctoinPromising
A natural extremolyte produced by microorganisms living in extreme environments. Acts as a molecular shield that protects skin cells from UV radiation, blue light, pollution, and dehydration.
- Research: Studies show Ectoin protects Langerhans cells from UV-induced damage and reduces skin aging markers caused by environmental stress.
- Benefit: Stabilizes cell membranes, prevents moisture loss, and calms irritation — making high-potency Vitamin C more comfortable.
Alpha-ArbutinProven
A biosynthesized brightening agent that gently inhibits tyrosinase activity, slowing melanin production without the irritation risks associated with hydroquinone.
- Research: Demonstrated to reduce melanin synthesis more effectively and with less irritation than beta-arbutin or kojic acid.
- Benefit: Gradually lightens dark spots, sun damage, and post-acne marks for a more even complexion.

Where it fits in your routine
ROUTINEBest used in the AM routine for daytime antioxidant protection. Apply to clean, dry skin before moisturizer and sunscreen. Can also be used in PM if not using retinol the same evening.
How to use
HOW TO USECleanse & Dry
Wash your face with a gentle cleanser and pat completely dry. L-Ascorbic Acid absorbs best on dry skin — applying to damp skin may cause extra tingling.
Apply 2–3 Drops
Dispense 2–3 drops onto clean fingertips. Gently press and pat the serum across your face and neck, avoiding the eye area. Do not rub vigorously.
Wait & Absorb
Allow 60–90 seconds for the serum to fully absorb before moving to the next step. The lightweight texture sinks in quickly with no sticky residue.
Follow with Moisturizer + SPF
Layer your moisturizer on top, then apply broad-spectrum SPF 30+ sunscreen as the final step. Vitamin C enhances sun protection but never replaces it.
Who is it for?
WHOPerfect for you if:
- You want to brighten dull, uneven skin tone
- You have dark spots, sun damage, or hyperpigmentation
- You're looking to reduce fine lines and boost firmness
- You want professional-grade antioxidant protection at an affordable price
- You prefer a clean, fragrance-free, oil-free formula
- You want a SkinCeuticals C E Ferulic alternative without the premium price tag
Consider alternatives if:
- You have extremely sensitive or easily irritated skin (start with 10% Vitamin C instead)
- You have active rosacea flare-ups — high-dose Ascorbic Acid may worsen redness
- You dislike the natural metallic/iron scent of pure L-Ascorbic Acid
- You prefer a thicker cream or gel-cream texture over a thin liquid serum
- You need a Vitamin C derivative that is stable at room temperature for longer periods
Skin type compatibility
SKIN TYPESOil-free, water-light formula absorbs instantly with zero greasiness. Niacinamide helps regulate sebum production and minimize pore appearance.
Hyaluronic Acid and Glycerin provide hydration, but dry skin types will benefit from layering a richer moisturizer on top for added nourishment.
Lightweight enough for oily zones, hydrating enough for dry patches. Balances well across all face zones without pilling or congestion.
The 15% concentration and low pH may cause initial tingling. Patch test first and introduce gradually. Ectoin helps calm irritation, but very reactive skin may prefer a lower concentration.
Non-comedogenic, oil-free, and fungal-acne safe. Niacinamide and Vitamin C help fade post-acne marks while the clean formula won't trigger breakouts.
Ideal choice — collagen-boosting Vitamin C combined with Pro-Xylane and Glutathione to address fine lines, firmness loss, and age spots simultaneously.

Budget-friendly alternatives (dupes)
DUPESNearly identical C+E+F formula with 20% L-Ascorbic Acid (slightly higher). Simpler ingredient list without the extra brightening agents (no Tranexamic Acid, Alpha-Arbutin, or Niacinamide). Comes in a pump bottle for better stability.
Award-winning formula with 15% L-Ascorbic Acid, Vitamin E, Ferulic Acid, and Hyaluronic Acid. Clean, straightforward ingredient list. Lacks the advanced brightening complex (no Tranexamic Acid or Alpha-Arbutin) found in the Lanmeri formula.
Popular Amazon best-seller with Vitamin C, E, and Hyaluronic Acid. Uses a blend of Vitamin C forms rather than pure L-Ascorbic Acid. No Ferulic Acid included, so less antioxidant synergy. Contains plant extracts some may find sensitizing.

Storage & shelf life
6 MONTHS6 months after opening. L-Ascorbic Acid oxidizes when exposed to air — use promptly for best results. Discard if serum turns dark orange or brown.
Store in a cool, dark place away from direct sunlight and heat. Refrigeration recommended to extend potency and slow oxidation. Keep the cap tightly closed after each use.
Amber glass dropper bottle (30ml). The dark glass helps protect from UV-induced degradation. Ensure dropper is sealed after each application to minimize air exposure.
Yes — 30ml is well under the 100ml / 3.4oz TSA carry-on liquid limit. Glass bottle requires careful packing to prevent breakage.
Frequently asked questions
FAQUse with caution. The main actives (Vitamin C, Vitamin E, Ferulic Acid) are generally considered safe during pregnancy. However, this formula also contains Tranexamic Acid and Alpha-Arbutin, which have limited safety data for use during pregnancy and breastfeeding. Consult your OB-GYN or dermatologist before incorporating this serum into your routine while pregnant or nursing.
Yes. According to ingredient analysis on SkinSort, this formula is fungal acne (malassezia) safe. It contains no fermented ingredients, fatty acids, esters, polysorbates, or other components known to feed the malassezia yeast responsible for fungal acne. This makes it one of the few C+E+Ferulic serums suitable for fungal acne-prone skin.
This serum already contains 15% Vitamin C, so there is no need to layer additional Vitamin C products on top. You can use it with AHAs/BHAs, but introduce them on alternate nights to avoid over-exfoliation. For retinol, use this serum in the morning and retinol at night — they complement each other well when separated. Avoid using Benzoyl Peroxide at the same time, as it can inactivate Vitamin C.
This serum is excellent for normal, oily, combination, acne-prone, and mature skin types. Its lightweight, oil-free formula absorbs quickly without greasiness. Dry skin types can use it but should follow with a richer moisturizer. Sensitive skin should approach with caution — the 15% concentration and low pH may cause tingling. Patch test first and consider starting with a lower-concentration Vitamin C serum.
Many users report an immediate brightening glow within the first 1–2 weeks. More significant results like improved texture, fading dark spots, and reduced fine lines typically become noticeable after 4–8 weeks of consistent daily use. Maximum anti-aging and collagen-building benefits develop over 3–6 months. Consistency is key — daily morning application paired with sunscreen delivers the best outcomes.
Apply this serum after cleansing and toning, but before your moisturizer and sunscreen. It works best on clean, dry skin in the morning as part of your AM routine. The order is: Cleanser → Toner (optional) → This Serum → Moisturizer → Sunscreen SPF 30+. It can also be used in your PM routine if you are not using retinol or strong exfoliating acids that same evening.
No — this serum has a comedogenic rating of 1 out of 5, meaning it is very unlikely to clog pores. The formula is completely oil-free and silicone-free, with no ingredients known to be comedogenic. It is also fungal acne safe. Users with acne-prone skin consistently report no breakouts from this product, and Niacinamide in the formula actually helps minimize pore appearance.
For best results, use within 6 months of opening. L-Ascorbic Acid is inherently unstable and begins to oxidize once exposed to air, light, and heat. Refrigeration can help extend potency. If the serum turns from its original light color to a dark orange or brown, it has oxidized and should be replaced. With daily use (2–3 drops), a 30ml bottle typically lasts 2–3 months.
Verdict: Lanmeri Pure Radiance 15% C E + Ferulic delivers the clinically proven gold-standard antioxidant trio (Vitamin C + E + Ferulic Acid) at roughly one-ninth the price of SkinCeuticals — and then goes further by including Tranexamic Acid, Alpha-Arbutin, Niacinamide, and Ectoin for enhanced brightening and barrier support. The formula is clean, fungal-acne safe, and impressively loaded with 19 purposeful ingredients. The main trade-offs are a shorter effective shelf life compared to patented formulations and limited brand transparency. If you want professional-grade antioxidant protection and visible brightening on a budget, this is one of the best value propositions in the Vitamin C serum market.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
