DAY POWER OPTIMIZER - Protection + Repair Serum


Antioxidants are essential for skin health and beauty. But not all are created equal. 

Did you know that close to 90% of visible skin damage is the result of sun+environmental exposure & only about 10% of visible skin aging is due to genetics? Because the majority of skin aging is environmental, this may be the most important skin serum you will use to ensure the future health of your skin.


You may have heard of antioxidants, particularly Vitamin C....but not all antioxidant Vitamin C products are created equal. Many are not formulated properly to make the ingredient stable long-term and even those that are, do not penetrate the stratum corneum due to hydrophilic (water-loving) and lipophilic (fat-loving) characteristics of ingredients. What's more, improperly formulated products can increase free radical activities on skin to cause more harm than good.

DAY POWER OPTIMIZER goes beyond conventional antioxidant Vitamin C formulas & combines scientifically proven effective concentrations of pure & potent complex of 15% Vitamin C, Vitamin E, Ferulic Acid, Pro-Vitamin B5 & Hyaluronic Acid & breakthrough line smoothing Octapeptide complex - all intensified and ultra-stabilized in a patented carrier system that allows ingredients to penetrate through multiple pathways and decrease irritation potential often associated with vitamin C treatments. This allows the ingredients to work efficiently on different levels to help hydrate, firm, and neutralize free radical damage plus oxidative stress that break down different layers of your skin. Ingredients are kept potent and targeted to provide protection and repair when and where it matters most. 

Our potent Vitamin C accumulates in the skin, so you get enhanced collagen production benefits without the need to reapply at night. What's more, tests show it can stay in your skin for 72 hours so even though, theoretically, you could use your C+ Skin Defender™ every 3 days, your best results of are obtained with daily use for optimum protection & repair. 

Clinical results show

  • A reduction of sunburned & sun-damaged cells by 96%
  • 92% reduction in human melanocyte cells
  • An almost 10 fold increase in photo-protection against UV damage, elevated anti-oxidant protection, and 8-fold increase in collagen synthesis for firmer-looking and feeling skin. 

  • Deep wrinkles are visibly reduced by 63% in approximately 1 month.

  • Hyperpigmentation is visibly reduced with advanced tyrosinase inhibiting activities by 73%.

  • Luminosity of skin is noticeably improved.

  • Skin is more refined with less visible large pores.
  • Skin’s defenses, barrier strength & hydration are measurably boosted.

  • Inflammation is significantly reduced along with hyperpigmentation from inflammatory flare-ups. 

With each use, you start to forgive the past and improve the future for smoother, firmer-feeling, more even-toned, radiant-looking skin.


After cleansing, smooth over face and neck, avoiding the eye area. Use as your first step in your daytime skincare regimen after cleansing. For external use only. Keep out of eyes. 


Anti-Irritation & Skin Strengthening Rescue for Stressed Skin

We go beyond “clean” to also be free from naturally-derived & synthetic fragrances, essential oils, and other commonly-used "natural" or synthetic skin irritants and sensitizers.


  • Aqua/water  improves the performance of hydrophilic ingredients
  • L-Ascorbic Acid - the most powerful and most well-studied form of vitamin C shown to provide results. However, it is also known to be extremely unstable, oxidize rapidly, and not suitable for sensitive skin. Our proprietary stabilization and delivery technology address these concerns allowing its powders to help repair and improve the look and feel of photo-damaged skin in terms of lines, pigmentation, and elasticity without the side effects (and the stickiness) often experienced with the leading vitamin C formulas. 
  • Ethoxydiglycol - solvent allowing for uniform blending of ingredients
  • dL-Tocopherol (Vitamin E antioxidant) 1% -  based on available research so far, skin scientists believe these have numerous benefits and are essential to skin cells due to their ability to delay damage from free radical activities. These antioxidants have the power to reduce inflammation and attack specific free radicals that cause inflammation. Their antioxidant powers may help reverse damage due to free radicals and potentially prevent wrinkles while making the skin appear more youthful.
  • Glycerin  plant-derived hydration booster that is one of the most effective humectants available to draw moisture deep into skin, protecting it from loss of water other harsh products, and helping it look smoother. 
  • SNAP-8™ - an octapeptide that reduces visible wrinkle depth by destabilizing the SNARE complex in skin that's involved neuronal excitability and facial muscles contractions. tests show that wrinkle depth is visibly reduced by up to 63% within one month of treatment. The face looks smoother as the look of fine lines and expression wrinkles fade. It offers an effective topical alternative for those who do not prefer or invasive procedures.
  • Ferulic Acid (antioxidant) 0.5%  helps reduce the effects of damaging free radicals on the skin and helps in skin’s repair and regeneration activities from environmental damage. It also works to enhance stability and efficacy of other antioxidants such as vitamins C and E.
  • Panthenol - also known as pro-vitamin B5, it's a humectant that attracts moisture to the skin and also acts as a skin moisturizer. It helps to soothe and soften skin while helping to promote a stronger barrier to defend against irritation and moisture loss.
  • Sodium Hyaluronate  - a form of hyaluronic acid that acts as a humectant to attract moisture to the deeper layers of skin helping to reduce dryness, inflammation, and the appearance of lines. Skin looks plumper and smoother.
  • PPG/Buteth-26 - used to restore and improve suppleness with conditioning properties that help reduce flakiness and other visible texture irregularities of skin. 
  • PEG-40 Castor Oil -  an emollient to help keep skin soft and help prevent moisture loss from skin.
  • Phenoxyethanol - one of the most effective broad-spectrum preservatives to help prevent the growth of fungi, bacteria, yeast, and mold.
  • Triethanolamine - used to help balance pH levels so ingredients can work at most ideal pH levels and helps the formula to work best with the natural pH of the skin.
  • Sodium Pyrosulfite - a preservative that helps enhance the effectiveness of other preservatives to allow for the most broad-spectrum protection and safety.

So good that I'm ordering a second bottle

For context: 30s + Combination Skin. This has been by far the best Vitamin C I have used due to its effects, absorption, and texture. It just WORKS. After pregnancy, the skin tone of my face changed quite drastically. I had areas that were darker and redder, especially near my nose. This product corrected those areas and evened out the skin tone. I have used product Vitamin C in the past, but they did not work well due to my skin sensitivity. The texture of this product feels closer to an essence (a thicker toner) than that of a traditional serum. It goes on smooth and absorbs quickly & easily. There is no oiliness! This product pairs well with the other Lex & Jong products (I use Synergist, Day Potion, and Night Potion). Smells light and pleasant. Use consistently and results will appear.

Gail Gross
The Best Vitamin C

I have used numerous vitamin C products over the years and Ideal Light Serum has been the most effective and the easiest on my very sensitive skin. I have had absolutely no issues with irritation using Ideal Light and have been using it ever since Brendan sent a generous sample with my purchase of the Synergist serum in October. I was more than delighted to receive a promotional complimentary full bottle with a recent purchase. I love everything I have tried from Lex & Jong and it is hard to chose a favorite, but I have found that Ideal Light Serum has become a necessity for my daily skin care routine. It reduces pore size, leaving my skin calmed, refined with a new glow and lift. Thank you, Brendan, for another great product.

Super supplement for your skin!

I have had such bad reactions to vitamin C products in the past, but WOW! I'm so happy to have met Brendan and tried his fabulous products. I was so hesitant to purchase yet another vitamin C product, but this is like nothing else I've used. I urge you to try this wonderful serum! Such a lovely, light texture, and no stinging or irritation. I feel like I'm doing something super healthy for myself and my skin's long term wellness.
