Product Details

Claro Que C is a fragrance-free vitamin C glow serum formulated with 15% pure vitamin C across three clinically active forms: Tetrahexyldecyl Ascorbate (THD), Ethyl Ascorbic Acid, and DP-C. Unlike traditional vitamin C serums, the formula delivers vitamin C through both the water and oil phases, helping maximize absorption and performance. The result is visibly brighter, more even skin with reduced dark spots, faded hyperpigmentation, and improved tone over time. Non-sticky, non-greasy, and clinically tested with 742 verified reviews. Finished with Dezi Youth Juice, a proprietary antioxidant blend of eight fruit extracts responsibly sourced in Mexico.

What’s inside

Key Ingredients:

  • Tetrahexyldecyl Ascorbate (THD): An oil-soluble form of vitamin C that penetrates deeper into skin to improve collagen synthesis, brighten, and even skin tone. One of the most stable and effective forms available.
  • Ethyl Ascorbic Acid (99%+ purity): A highly stable, water-soluble form of vitamin C proven to brighten sun-damaged skin, fade dark spots, and deliver powerful antioxidant and anti-aging effects.
  • DP-C (Ascorbic Acid & Glutathione): Ascorbic acid and glutathione conjugated to gold submicroparticles that synergistically enhance skin penetration for dramatically deeper vitamin C delivery.
  • Green Plum: Energizes dull looking skin, induces skin brightening, reduces the appearance of skin redness, and improves overall skin tone evenness. 
  • Dezi Youth Juice: Proprietary blend of eight antioxidant-rich fruit extracts responsibly sourced in Mexico, including plum, dragon fruit, açaí, tamarind, mango, soursop, guava, and avocado.
  • Fragrance-free, paraben-free, triclosan-free, mineral oil-free, cruelty-free, gluten-free, and vegan.

How To Use It

Apply 1-2 pumps to clean, dry skin immediately after cleansing, before moisturizer and sunscreen. Use morning or night. Shake well before each use.

For best results, use daily. Morning use is ideal since vitamin C helps protect skin from environmental stressors like sun and pollution throughout the day. Always follow with sunscreen in the morning.

If you have sensitive skin, patch test first. Apply a small amount to your jawline, wait 10-12 hours, and if there's no reaction, start with once a week and build up from there. Avoid layering with retinol or AHAs/BHAs.

For external use only. Avoid contact with eyes. Discontinue use if irritation occurs.

Recommended For

All skin types including sensitive skin. Patch test recommended for sensitive skin before first use.

FAQ’s

Is it fragrance-free? Yes, completely fragrance-free.

Does it help with dark spots and hyperpigmentation? Yes. All three forms of vitamin C in this formula target dark spots and uneven skin tone with consistent use.

Is it sticky or greasy? Nope. Non-sticky, lightweight, and absorbs quickly under moisturizer and SPF.

Is it suitable for sensitive skin? Yes, with a caveat. It's formulated to be well-tolerated, but because it's a potent 15% vitamin C formula, sensitive skin should patch test first. Apply a small amount to your jawline, wait 10-12 hours, and if there's no reaction, start using it once a week and build from there.

When in my routine do I use it? Apply immediately after cleansing, before moisturizer and SPF. Morning use is ideal since vitamin C helps protect against environmental stressors throughout the day.

Can I use it with other actives? Vitamin C plays well with most ingredients including niacinamide, vitamin E, and ferulic acid. If you experience irritation, avoid using it on the same days you use retinol or AHAs/BHAs.

What makes this different from other vitamin C serums? Most vitamin C serums use a single form. Claro Que C uses three: one oil-soluble (THD), one water-soluble (Ethyl Ascorbic Acid), and one that uses gold particles to enhance skin penetration (DP-C). That multi-form approach means vitamin C is absorbed at more levels of the skin.

Does it oxidize or expire? The serum should appear white or light yellow. If it turns significantly darker it may be oxidized. Store in a cool, dark place and shake well before each use.

Is it oil-free? Yes, there are no animal, vegetable, or mineral oils in the formula.

Is it vegan? Yes, fully vegan and cruelty-free.

Is it good for acne-prone skin? Yes. Vitamin C helps fade post-acne dark spots and hyperpigmentation, and the non-comedogenic formula won't clog pores.

    Skin Reaction

    My friend gifted me the travel set to test out before purchasing the full size. I ended up having no reaction and went with purchasing the full size items. I broke out in a rash on my chin, continued the cleanser and stopped the claro que C. I reintroduced it, and it broke me out again. It's strange that only the full size item gave me a reaction. Bummer! I really wanted to like and support your brand.

    Pump doesn’t work

    I am in the first couple weeks of using this product and while I can’t fully speak on how well the formula is quite yet, my issue is the pump on this component. It never works . Every time I go to use this product, the pump spits out a tiny bit and then nothing. I’ll be constantly pumping it for more and it doesn’t work. So I’ve been unscrewing the top to scoop some out. The component is stunning and heavy. But the pump is horrible. Maybe I got a faulty one. But at this price, I’m not willing to repurchase to hope a new one is better.
