If you’ve been missing out on Spanish brand Niche Beauty Lab and the gems tucked under their umbrella, consider this your nudge to start exploring. One standout worth your immediate attention is the THERAMID C-Tetra EF Serum, a product I’ve genuinely loved and fully intend to keep in rotation.
What is it?
THERAMID C-Tetra EF Serum is a brightening, antioxidant serum which helps tackle dark spots, dullness and uneven skin tone.
What Do I Think?
This is not just another antioxidant serum. It’s a powerhouse of Vitamin C (a hefty 20%), paired with 1% Vitamin E and 0.5% Ferulic Acid—the ultimate dream team for tackling free radicals, brightening skin, and softening pigmentation. It also stimulates collagen production, making it an excellent daytime ally for anyone looking to protect and perfect their skin in equal measure.
What really sets this serum apart is its texture. A silky gel-cream that absorbs beautifully without a hint of stickiness, it plays nicely with everything from light moisturisers to richer SPF formulas. There’s no peeling or pilling here – just a seamless addition to your morning routine.
The results? Glowing, brighter skin with noticeably softened dark spots. For me, it was especially effective at fading those stubborn post-pimple marks and delivering an overall youthful luminosity. It’s the kind of product that makes you look in the mirror and think, ah, there it is—the glow I’ve been missing.
If you’re on the hunt for a hardworking, no-nonsense antioxidant serum that delivers visible results without fuss, THERAMID C-Tetra E.F. Serum is one to have on your radar. Consider yourself officially awakened.
Would I recommend?
Yes! I saw good results from it.

Key Ingredients
- 20% Vitamin C
- Vitamin C Tetra: A fat soluble derivative of Vitamin C. Gentler and kinder to the skin than the pure form Ascorbic Acid. It stimulates collagen production, provides antioxidant protection against free radicals, has an ability to visibly improve wrinkles and fine lines, and improve skin tone and brightness.
- Ascorbosilane: A stable, water-soluble form of Vitamin C derivative. It acts to protect the skin from external aggressions thanks to its antioxidant properties and role in collagen synthesis for firmer, more protected skin.
- Ascorbyl Glucoside: A stable and water-soluble derivative of Vitamin C. In addition to the antioxidant benefits of Vitamin C, it visibly improves radiance and skin tone for healthy, younger-looking skin.
- 1% Vitamin E: An antioxidant, which is naturally present in the skin and acts by neutralizing free radicals. It acts in synergy with vitamin C, enhancing its antioxidant effect to keep skin protected throughout the day.
- 0.5% Ferulic Acid: Plant-derived antioxidant that helps protect the skin from damage caused by free radicals and sun exposure, preventing premature skin aging. It also acts in synergy with Vitamin C and E, improving the stability and efficacy of the formula.
How I Use It
I use this in my morning routine, after a hydrating or exfoliating toner and before moisturiser and sunscreen.
