Brightening & Tone Correcting

10% L-Ascorbic Acid inhibits melanin production, fading dark spots and evening skin tone for a visibly radiant complexion.

Antioxidant Shield

Ferulic Acid stabilizes Vitamin C and doubles photoprotection, shielding skin from UV damage and environmental stressors.

Multi-Layer Hydration

4 types of Hyaluronic Acid target different skin layers, creating a 3D moisture network that plumps and hydrates from within.

Anti-Aging & Collagen Boost

Clinically proven to stimulate collagen synthesis at 10% concentration, reducing fine lines and improving skin firmness over time.

Botanical Soothing Complex

Green Tea Extract, Licorice Root, and Willow Bark provide additional antioxidant, anti-inflammatory, and calming benefits.

Prebiotic Skin Support

Alpha-Glucan Oligosaccharide nourishes beneficial skin microbiome, strengthening the natural barrier and resilience.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding

Contains Salix Purpurea (Willow) Bark Extract, a natural salicin source related to salicylic acid. While Vitamin C and Ferulic Acid are generally safe, consult your OB-GYN before use during pregnancy or nursing due to the willow bark content.

Fungal Acne (Malassezia) Safe

Formula is free of oils, fatty acids, esters, and polysorbates that feed malassezia yeast. Safe for fungal acne-prone skin.

Low Comedogenic Risk (1/5)

Oil-free, silicone-free water-based formula with non-comedogenic ingredients. Very unlikely to clog pores or trigger breakouts.

Contains Fragrance

Includes Parfum along with fragrance allergens Limonene, Linalool, and Benzyl Salicylate. Patch test first if you have fragrance sensitivities.

Sunscreen Reminder

Vitamin C boosts UV protection but does not replace sunscreen. Always apply SPF 30+ as the last step of your morning routine.

Sensitivity Note

L-Ascorbic Acid at 10% may cause mild tingling on first use, especially on sensitive skin. This is normal and usually subsides within minutes. Introduce gradually if new to Vitamin C serums.

Ingredient breakdown

INGREDIENTS

Ascorbic Acid (Vitamin C) 10%Proven

The gold-standard, pure form of Vitamin C (L-Ascorbic Acid). A powerful antioxidant clinically proven to brighten skin, boost collagen synthesis, inhibit melanin production, and protect against UV-induced free radical damage.

  • Efficacy: Clinically effective at 5–20% concentration; this serum's 10% sits in the ideal range for both efficacy and tolerability.
  • Collagen: Stimulates fibroblasts to produce collagen types I and III, improving skin firmness and reducing fine lines.
  • Brightening: Inhibits tyrosinase enzyme, reducing melanin production and fading hyperpigmentation over time.
  • Synergy: Ferulic Acid in this formula stabilizes Vitamin C and enhances its photoprotective effects (Lin et al., 2005).
Pure L-Ascorbic Acid is inherently unstable and can oxidize when exposed to light and air. Discard if the serum turns dark orange or brown. Store in a cool, dark place.

Ferulic Acid 0.5%Proven

A plant-derived antioxidant found naturally in rice, wheat, and oat bran. Renowned for stabilizing Vitamin C and dramatically boosting its photoprotective power.

  • Landmark Study: A 2005 study by Lin et al. found that 0.5% Ferulic Acid added to a Vitamin C + E solution doubled the formula's photoprotection against UV damage.
  • Stabilizer: Helps prevent the rapid oxidation of L-Ascorbic Acid, extending the effective life of the serum.
  • Anti-aging: Independently fights free radicals, reduces fine lines, and helps prevent UV-caused cell damage.
Easily absorbed by the skin and pairs synergistically with Vitamin C for enhanced results. The 0.5% concentration matches the clinically studied dosage.

4-Type Hyaluronic Acid Complex Multi-weightProven

A multi-molecular weight blend of Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate, Sodium Acetylated Hyaluronate, and Hydrolyzed Sodium Hyaluronate. Targets different skin layers for comprehensive hydration.

  • Crosspolymer: Claims 5x the water-binding capacity of standard HA; provides long-lasting surface moisture and acts as an antioxidant.
  • Standard HA: High molecular weight for surface hydration and barrier protection.
  • Acetylated HA: Enhanced skin adhesion for prolonged moisturizing effects.
  • Hydrolyzed HA: Low molecular weight fragments that penetrate deeper skin layers for internal plumping.

Camellia Sinensis Leaf Extract (Green Tea)Proven

Rich in catechins, particularly EGCG—one of the most potent natural antioxidants. Provides UV protection, anti-inflammatory benefits, and helps neutralize free radicals alongside Vitamin C.

  • Antioxidant: EGCG has been shown to protect skin cells from UV radiation and environmental pollution.
  • Anti-inflammatory: Calms irritation and redness, making it beneficial for sensitive skin types.

Glycyrrhiza Glabra Root Extract (Licorice)Proven

A well-researched botanical brightener containing glabridin. Works synergistically with Vitamin C to inhibit melanin production and calm inflammation.

  • Brightening: Glabridin inhibits tyrosinase activity, complementing Vitamin C's melanin-reducing effects.
  • Soothing: Anti-inflammatory properties help reduce redness and irritation from active ingredients.

Alpha-Glucan Oligosaccharide (Prebiotic)Promising

A prebiotic sugar that selectively feeds beneficial skin bacteria, helping strengthen the microbiome barrier and improve skin resilience against environmental stressors.

  • Microbiome: Promotes growth of beneficial flora while discouraging harmful bacteria, supporting skin barrier function.
  • Defense: Enhances the skin's innate immune response for stronger natural protection.

Who is it for?

WHO

Perfect for you if:

  • You have dull, tired-looking skin that needs a radiance boost

Frequently asked questions

FAQ

Use with caution. While Vitamin C (Ascorbic Acid) and Ferulic Acid are generally considered safe during pregnancy, this formula contains Salix Purpurea (Willow) Bark Extract, which is a natural source of salicin—a compound related to salicylic acid. Most dermatologists advise avoiding salicylate-containing products during pregnancy. Consult your OB-GYN or dermatologist before incorporating this serum into your routine while pregnant or breastfeeding.

Yes. This serum is fungal acne safe. The formula does not contain oils, fatty acids, fatty acid esters, or polysorbates that feed malassezia yeast. The water-based formula with glycerin, hyaluronic acid, and plant extracts is compatible with fungal acne-prone skin.

Yes, but with care. Vitamin C works at a low pH, and layering it with other actives like retinol, AHA, or BHA can increase irritation risk. For best results, use Vitamin C in the morning and retinol at night. If using AHA/BHA, apply them on alternate evenings or wait 15–20 minutes between applications to let pH levels normalize. Never combine with benzoyl peroxide, which can deactivate Vitamin C.

This serum is formulated for all skin types. It works especially well for normal, oily, and combination skin due to its lightweight, oil-free texture. Dry skin types will benefit from the 4-type HA complex but may need an additional moisturizer. Sensitive skin types should patch test first, as the 10% L-Ascorbic Acid and fragrance may cause irritation—start with every other day use and build up tolerance.

Many users report an immediate glow and hydration boost from the first application. Visible brightening and tone evening typically appear within 2–4 weeks of consistent daily use. Significant improvements in dark spots, hyperpigmentation, and fine lines generally require 8–12 weeks of regular application. Consistency is key—use daily for best results.

Apply after cleansing and toning, but before moisturizer and sunscreen. The general rule is thinnest to thickest texture. This serum fits at step 3 in your routine: Cleanser → Toner → This Serum → Moisturizer → Sunscreen (AM). You can use it in both morning and evening routines. In the morning, always follow with SPF 30+ sunscreen as your final step.

This serum has a comedogenic rating of 1 out of 5, meaning it is very unlikely to clog pores. The formula is oil-free, silicone-free, and water-based. Key ingredients like Glycerin (comedogenic rating 0), Hyaluronic Acid (rating 0), and Ascorbic Acid are all non-comedogenic. It is also fungal acne safe. However, everyone's skin is different—if you are extremely acne-prone, do a patch test on a small area first.

This serum has a PAO (Period After Opening) of approximately 6 months. However, because L-Ascorbic Acid is inherently unstable, the actual effective life depends on storage conditions. Store in a cool, dark place (refrigerator is ideal) and close the dropper tightly after each use. If the serum changes color from clear/light yellow to dark orange or brown, it has oxidized and should be discarded. At 1–2 drops per day, the 30ml bottle typically lasts about 30 days.

— Skincarisma verdict
4.0 / 5 ★★★★☆

Verdict: The Purest Solutions Vitamin C Serum delivers solid brightening and antioxidant performance at a very competitive price point. The 10% L-Ascorbic Acid with 0.5% Ferulic Acid combination is clinically grounded, and the addition of a 4-type Hyaluronic Acid complex and prebiotics adds meaningful hydration and skin barrier support. It's an excellent entry-level Vitamin C serum for those new to active ingredients. The main drawbacks are the absence of Vitamin E (which would complete the legendary C+E+Ferulic trio), the inclusion of fragrance, and the dropper packaging that exposes the unstable formula to air. For the price, it punches above its weight—but experienced Vitamin C users seeking maximum potency may want to look at higher-concentration, fragrance-free alternatives.

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.

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.
