The Vitamin C Showdown: Klairs vs. The Ordinary
Vitamin C has become one of the most popular ingredients in skincare for its ability to brighten, even skin tone, boost collagen, and offer antioxidant protection. Two cult favorite Vitamin C serums are the Klairs Freshly Juiced Vitamin C Serum and The Ordinary’s options like the Suspension 23% + HA Spheres 2%. But which C serum reigns supreme? Here’s an in-depth comparison of formulations, performance, texture, and overall user experience to help you choose.
Key Ingredients and Formulations
First, let’s analyze the key ingredients in Klairs and The Ordinary Vitamin C serums:
Klairs Serum
- 5% Pure Vitamin C (Ascorbic Acid)
- Sodium Ascorbyl Phosphate (a Vitamin C derivative)
- Water, glycerin, collagen, hyaluronic acid
With 5% ascorbic acid plus supporting antioxidants like vitamin E, Klairs provides a gentle, hydrating formula great for sensitive skin. It uses an oil-soluble Vitamin C derivative for enhanced absorption.
The Ordinary Serums
- Ascorbic Acid 8% + Alpha Arbutin
- Vitamin C Suspension 23% + HA Spheres
- Ascorbyl Glucoside Solution 12%
- Magnesium Ascorbyl Phosphate 10%
The Ordinary offers several potent Vitamin C options with 23% and 12% concentrations plus brightening agents like alpha arbutin. The lightweight textures use suspending agents for stability. Most formulations are water-based.
For those new to Vitamin C, Klairs' gentle formula may be most suitable. But The Ordinary offers more advanced options for experienced users targeting intense brightening.
Brightening and Skin Tone Correction
Now let’s analyze the brightening and tone correcting abilities of these two serums.
Klairs Serum
The Klairs serum uses 5% ascorbic acid at a pH below 3.5 for effective brightening. In a clinical trial, it reduced pigmentation by 20% after 4 weeks of use. It inhibits melanin production and exfoliates for improved tone and clarity.
However, with only 5% Vitamin C, it may take longer to see dramatic results compared to higher concentrations. Best for mild to moderate hyperpigmentation and evening overall complexion.
The Ordinary Serums
With serum options ranging from 8-23% Vitamin C plus brighteners like alpha arbutin, The Ordinary targets more advanced pigmentation. The 23% suspension provides the strongest brightening of the bunch.
In a study, 23% Vitamin C reduced dark spots by 49% in 8 weeks. Reddit users report rapid results fading acne marks and melasma. For fast correction of discoloration, The Ordinary is the clear winner.
For subtle glow and evening of skin tone, Klairs is great. But The Ordinary takes the lead for combating tough hyperpigmentation.
Texture, Application, and Sensation
Vitamin C serums range in texture, so let’s compare:
Klairs Serum
The Klairs serum has a smooth, viscous texture without stickiness or grittiness. It contains moisture-binding glycerin and smoothing collagen for a soft, supple feel.
The serum absorbs rapidly without residue or pilling. It has a refreshing citrus scent and causes no irritation, stinging, or redness even on sensitive skin.
The Ordinary Serums
The Ordinary C serums have lightweight, watery textures. The 23% suspension contains silicone spheres to minimize powdery grittiness from high acidity. Still, minor graininess is felt upon application.
The serums absorb quickly but may pill with other products. They cause mild tingling when first applied. The high acid concentrations make them unsuitable for very sensitive skin.
For a soothing, gentle application, Klairs is the winner. But The Ordinary offers sheer and fast-absorbing options for oily or acne-prone skin not prone to irritation.
User Experience and Final Verdict
Finally, let’s summarize user experiences with these two serums:
Klairs Serum
Users love Klairs for its instant brightening and hydration without irritation. The creamy serum leaves skin plump and refreshed. Many saw a reduction in acne scars, sun spots, and melasma after 1-2 months use.
However, some wanted even faster results. Those with very oily or clog-prone skin found it too rich. Overall, Klairs receives rave reviews for glow and tolerability.
The Ordinary Serums
Users are blown away by the rapid pigment-fading and glow achieved with The Ordinary’s serums, particularly the 23% suspension. Within 2 weeks, many see drastic fading of melasma, acne marks, and sun spots.
However, the high acidity causes stinging and redness for some. Those with dry skin may find the serums too harsh. But oily and acne-prone skin can tolerate them well.
For an ultra-gentle formula providing modest brightening, choose Klairs. For potent pigment correction for tolerant skin, The Ordinary reigns supreme.
Whichever you choose, be diligent with sunscreen, as Vitamin C makes skin more sun-sensitive. Glow on!
In summary, while both Klairs and The Ordinary make phenomenal Vitamin C serums, The Ordinary tends to provide faster and more dramatic brightening results. But Klairs offers a much more gentle, soothing formula suited to sensitive skin. Evaluate your skin goals and type to choose the best C serum for your needs.
