• The Ingredients & Benefits

| Clinique Fresh Pressed Daily Booster with Pure Vitamin C 10%

This booster works as a daily treatment to help visibly rejuvenate skin from the outside, giving your de-aging a simple and seamless reinvigoration. From the first application, it helps brighten skin. Over time it helps reduce the appearance of age spots and the look of line and wrinkles. Pure vitamin C naturally degrades when exposed to oxygen, so it's most powerful when fresh. This stay-fresh packaging isolates the pure vitamin C until activation so it maintains its freshness and full power for maximum results.

| Kiehl's Powerful-Strength Line-Reducing Concentrate

Kiehl's original formula, infused with 10.5% pure vitamin C, now has an additional 2% of vitamin Cg for increased potency. Vitamin Cg is a vitamin C derivative that activates once absorbed into the upper layers of the skin's surface and is used in anti-wrinkle skin care products to help reduce facial lines over time. Fragmented hyaluronic acid has also been added to this formula to help instantly smooth skin. 

Through clinical studies, this serum has been shown to help decrease the appearance of fine lines and wrinkles and improve skin radiance and texture, even helping to reduce the appearance of forehead lines, marionette lines and deep-set wrinkles after four weeks of regular use.

| Drunk Elephant C-Firma Day Serum

This revolutionary vitamin C serum contains 15% pure L-ascorbic acid (a potent form of vitamin C), 0.5% ferulic acid and 1% vitamin E - supported by a host of antioxidants and enzymes - which work to neutralise aggressors and replenish precious lipids to diminish visibility of lines and pigment patches. 

Potently formulated with pumpkin ferment extract and sodium hyaluronate crosspolymer, C-Firma™ helps to enzymatically dissolve surface dead skin cells as it intensely hydrates. The result is a noticeably diminished appearance of photodamage and aging, replaced by incredible radiance and luminosity.

• Reviews

Freshness is particularly important with an ingredient like Vitamin C — due, of course, to its instability in the presence of light, air, and a multitude of other ingredients used in skin care. Clinique wisely packages Fresh Pressed in a set of four to assure fresh activation, potency and stability. It's a really well-rounded, well-formulated serum. Honestly, it's the perfect boost for stepping up your game. 

Kiehl's has done a fantastic job formulating their Powerful-Strength Line-Reducing Concentrate; it feels amazing on the skin and you can notice visible results practically after one-two weeks of using it. It is a great product for those of you who are 30+ and are on a hunt for effective and potent Vitamin C products, those that will not burn your skin off or cover it in blackheads or pustule. 

When it comes to serum, especially active ingredients, please invest a bit more in. Drunk Elephant C-Firma Day Serum is a good value for money because the formula is really excellent quality. No ingredients were used randomly and you can definitely feel it! The packaging is also excellent, it's such a nice bottle that also preserves the formula very well. Yes, it's $80 but also it's going to do so much for your priceless skin.
