3% Stable Vitamin C

Uses 3-O-Ethyl Ascorbic Acid — a highly stable, light- and heat-resistant form of Vitamin C that brightens skin and evens tone without oxidizing quickly.

Ferulic Acid Synergy

Ferulic Acid boosts Vitamin C stability up to 8x and adds its own depigmenting and correcting benefits for visibly improved skin tone.

Turmeric Extract

Curcuma Longa Root Extract revitalizes, brightens, smooths, and softens the epidermis with multi-directional antioxidant care.

Humectant-Rich Hydration

Propanediol, Glycerin, and Panthenol work together to deeply hydrate, soothe, and strengthen the skin barrier.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding Safe

Contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Topical Vitamin C derivatives like Ethyl Ascorbic Acid are widely considered safe during pregnancy. Always consult your doctor.

Fungal Acne (Malassezia) Safe

Free from ferments, fatty acids, esters, polysorbates, and oils that feed malassezia yeast. This clean, water-based formula is safe for fungal acne–prone skin.

Non-Comedogenic (0/5)

Oil-free, lightweight gel formula with no known pore-clogging ingredients. Comedogenic rating of 0 — extremely unlikely to cause breakouts.

No Known Allergens

Fragrance-free (no parfum or essential oils). Free from common sensitizers like alcohol denat., SLS, and parabens.

Contains CI 19140 (Yellow Dye)

This is a cosmetic colorant used to give the serum its yellow hue. Rarely, it may cause sensitivity in individuals allergic to tartrazine. Patch test if concerned.

Daily SPF Required

Vitamin C increases photosensitivity. The brand recommends using SPF 50 daily while using this serum to protect skin and maximize brightening results.

Ingredient breakdown

INGREDIENTS

3-O-Ethyl Ascorbic Acid 3%Promising

A highly stable Vitamin C derivative that is resistant to light and temperature degradation. It dissolves in both water and oil, penetrates skin efficiently, and converts to pure ascorbic acid within the skin (with 86.4% Vitamin C content — higher than most derivatives).

  • Brightening: Clinical in-vivo data shows 2% EAC can improve skin tone and reduce pigmentation.
  • Antioxidant: Provides free-radical protection and anti-inflammatory benefits.
  • Stability: Remains effective far longer than pure L-Ascorbic Acid without turning brown.
At 3%, this is above the clinically studied threshold of 2%, making it an effective concentration for brightening.

Ferulic Acid ~0.5%Proven

A potent plant-derived antioxidant that works synergistically with Vitamin C. It is well-documented for stabilizing and enhancing the performance of ascorbic acid formulations.

  • Stability Booster: Can increase Vitamin C stability up to 8x according to research.
  • Depigmenting: Has its own skin-brightening and correcting properties.
  • Photoprotection: Helps neutralize UV-induced free radicals when paired with Vitamin C.

Curcuma Longa (Turmeric) Root Extract ~1%Promising

A traditional botanical extract known for its anti-inflammatory and antioxidant curcuminoid compounds. Turmeric has been used for centuries in Ayurvedic skincare for its brightening properties.

  • Anti-Inflammatory: Curcumin helps calm redness and irritation.
  • Brightening: Inhibits tyrosinase activity to help even skin tone.
  • Anti-Aging: Antioxidant properties protect against environmental stress.

Panthenol (Provitamin B5) ~1%Proven

A well-researched humectant and skin-soothing ingredient that penetrates deep into skin layers. Converts to Vitamin B5 in the skin, supporting barrier repair and moisture retention.

  • Hydration: Attracts and holds moisture in the skin for lasting hydration.
  • Barrier Repair: Supports the skin's natural healing and repair processes.
  • Soothing: Reduces irritation and redness, ideal alongside active ingredients.

Propanediol & Glycerin ~6% / ~2%Proven

Two powerful humectants that form the hydrating backbone of this serum. Propanediol is a plant-derived alternative to propylene glycol, while Glycerin is one of the most studied and effective moisturizing ingredients in skincare.

  • Humectancy: Combined humectant rating of 9.3/10 according to CreamScan analysis.
  • Skin Feel: Propanediol provides a silky, non-sticky finish.
  • Compatibility: Glycerin is effective from 3% and has a comedogenicity rating of 0.
This is a purely humectant serum (no occlusives). Follow with a moisturizer to seal in hydration and prevent transepidermal water loss.

Frequently asked questions

FAQ

Yes. This serum contains no retinoids, salicylic acid, hydroquinone, or any other ingredients commonly flagged as unsafe during pregnancy or breastfeeding. The key active, 3-O-Ethyl Ascorbic Acid, is a Vitamin C derivative widely considered safe for topical use during pregnancy. However, always consult your OB-GYN or healthcare provider before adding new skincare products to your routine during pregnancy.

Yes. This formula is free from ferments, fatty acids, esters, polysorbates, and oils that are known to feed malassezia yeast. The water-based gel formula with only 17 ingredients is one of the cleanest Vitamin C serums available for fungal acne–prone skin.

Yes, but with care. Since this serum is designed for morning use, a simple approach is to use this Vitamin C serum in the morning and your retinol or AHA/BHA products in the evening. Combining Vitamin C with acids in the same routine can increase irritation for sensitive skin. If layering, apply the Vitamin C serum first, wait a few minutes, then follow with your other actives.

This serum works for all skin types but is especially well-suited for oily, combination, and acne-prone skin due to its lightweight, oil-free, non-comedogenic gel formula. Dry skin types will benefit from adding a richer moisturizer on top, since the formula is purely humectant with no occlusive ingredients.

According to the brand and user reviews: immediate hydration and freshness from the first use; visible brightening and lightening of fresh acne marks after about 2 weeks; and noticeable smoothing, evening of skin color, illumination and nourishment after 1 month of consistent daily use.

Apply in the morning after cleansing and toning (if you use a toner). Massage onto face, neck, and décolleté, avoiding the eye area. Wait for it to absorb, then follow with your moisturizer and SPF 50 sunscreen. This is a morning-only serum — the brand specifically recommends AM use.

No. This serum has a comedogenic rating of 0 out of 5. It contains no oils, silicones, or heavy emollients. The formula is water-based with humectants (Propanediol and Glycerin) that have a comedogenicity rating of 0. It is one of the safest options for acne-prone and breakout-prone skin.

The recommended period after opening (PAO) is 6 months. The Ethyl Ascorbic Acid used in this serum is significantly more stable than pure L-Ascorbic Acid, so the product is resistant to oxidation and browning. Store in a cool, dry place with the cap tightly sealed. Discard if the color or smell changes significantly.

— Skincarisma verdict
4.2 / 5 ★★★★☆

Verdict: The Bielenda Skin Clinic Professional Vitamin C Serum is an excellent value-for-money brightening serum that punches above its price point. With a clean 17-ingredient formula featuring 3% stable Vitamin C boosted by Ferulic Acid and Turmeric, it delivers visible brightening and hydration within weeks. Its standout advantages are its fungal acne safety, pregnancy compatibility, and non-comedogenic profile — making it one of the safest Vitamin C serums available. The trade-off is a lower Vitamin C concentration compared to premium competitors, and the lack of Vitamin E in the formula. Best suited for those seeking a gentle, daily brightening serum at a budget-friendly price — especially if you have oily, combination, or acne-prone skin.

question
lightbulb What are Notable Effects & Ingredients?

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.

muscle Pro Tip Alert!

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.

lightbulb What is the Ingredient Safety Breakdown?

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.

muscle Pro Tip Alert!

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.
