Reviews
The Pre-dissolved solution is excellent. Ferulic Acid is an amazing skincare ingredient (potent antioxidant, protects other sensitive antioxidants from light degradation, UV protection) but is absolutely ineffective if it isn't solubilized correctly. Makes adding to any Serum Base or w/o emulsion easy. Love using it (at 6%; so active 0.5%) with the Resveratrol Fluid (10%; active 1%) and Green Tea Extr for potent nighttime brightening treatment... ...»

This ingredient has done more for my skin than anything else I've ever used. I put it into a spray facial toner and use it morning and night. I noticed the effects immediately, they were that dramatic. I will use this forever, no question... ...»

I've been using Bulkactives green tea EGCG for four years. No complaints, it blends nicely my DIY anti-aging cream. I can feel a bit of toning and definitely notice the anti-inflammatory effects on my skin. Two observations that keep the rating 4 stars instead of 5: (1) A package of green tea contains significantly less weight/volume than the package of grape seed extract that I order from bulkactives. The two are combined in equal amounts in the anti-aging cream, so I find myself running o.. ...»

I ordered the 50 gm after being very pleased with the smaller size. Although it's pricey the quality is outstanding. This is the safest way to add Vit C to your formulations as it's not nearly as fussy as the powder. I've made both serums and creams with this product and have been very pleased with the outcomes! Highly recommend!.. ...»

I am very happy with both the quality and packaging of the Ferulic acid I ordered. It came in foil packets (I ordered two). Will buy from them again as I use the product in my Vitamin C serum to maintain the PH needed... ...»

Buy Carnitine (L-Carnitine) For Skin Care

Carnitine is a naturally occurring substance, necessary for fat and glucose metabolism in human body cells. Primary function of carnitine in pharmacy is the reduction of advanced glycation end products (AGEs). AGEs are proteins, damaged by reactions with sugars, therefore glycation is most prominent in diabetes patients. It also occurs in many other diseases, as well as natural ageing processes. Dermal carnitine applications reduce the level of glycated collagen and promote synthesis of new protein. Since it is involved in lipid metabolism, carnitine is used for acne treatment. It effectively reduces sebum secretion and skin oiliness. Carnitine preparations also improve other aspects of the skin, such as tonicity, and reduce cellulite. Finally, it aids skin regeneration after damage, such as burns, and promotes blood vessel formation.  Regretably, due to Candian law and PayPal regulations, this product may NOT be shipped to Canada.

Key beneftis of Carnitine in skin care:

  • Oil/sebum control [4] [5]
  • Glycation inhibition and repair [1] [3]
  • Increase cellular energy production [1] [3]
  • Anti-acne [5]
  • Restore barrier function [6] [7]
  • Wound-healing support [8]

Carnitine (L-Carnitine)

About L Carnitine in DIY Skin Care

Carnitine (also L-carnitine or CA) is a naturally occurring substance, necessary for the cellular metabolism of glucose, fat and related compounds. Since these metabolic processes occur in most cells of the body, carnitine deficiency is associated with a wide range of diseases, such as muscle weakness, cardiac hypertrophy and accelerated atherosclerosis [1], [2]. Most importantly, carnitine helps to reduce protein glycation levels.

Glycation is a detrimental protein change that occurs in typical ageing processes. It involves a non-specific reaction between various sugars and proteins, especially collagen [3]. The damage brought on by such reactions is irreversible and results in dysfunctional protein aggregates, called advanced glycation end products (AGEs). AGE formation proceeds faster under elevated blood sugar levels, typically caused by diabetes, but they are also involved in the development of other disorders, among them osteoporosis, Alzheimer’s disease and cancer [1]. Carnitine was shown to be successful at inhibiting collagen glycation in rats that were fed on a high-sugar diet [3].

Furthermore, it reduced the AGE levels even more than commercially used antiglycation agent aminoguanidine, and also enhanced glucose metabolism in the diaphragm. Research on humans also confirms this conclusion, indicating that carnitine successfully reduces AGE levels in skin [1]. It is even suggested for management of adverse chemo- and radiotherapy effects. Recent studies have found that carnitine reduces therapy-caused damage to various organs and possibly even fatigue from chemotherapy [2].

In skin care, carnitine is a favored ingredient for several purposes.

Due to its role in lipid metabolism, it is known to inhibit sebum secretion and thus reduce skin oiliness. Applying 2 %-carnitine containing cream for 3 weeks was enough to significantly reduce both lipid content and sebum production in human sebaceous glands [4]. The same effect is utilized in anti-acne preparations with carnitine. In a study of mild to moderately severe acne, volunteers used a face cleanser with carnitine for 8 weeks. Total lesion count, sebum production, bacterial colonization, were all reduced; pustule count decreased 5 times, and general life quality of the subjects (measured by a questionnaire test) was improved [5].

Carnitine can also improve skin appearance in other ways. It is involved in skin cell proliferation, as it was shown to increase epidermal thickness both in healthy skin and during regeneration after wounds [6], [7]. Using a carnitine-containing preparation for 12 weeks resulted in various esthetic improvements of the skin, such as decreased cellulite and improved tonicity [6]. It is also known to promote wound healing, likely due to increased collagen synthesis, skin cell migration or energy release [7]–[9]. This effect is especially important in patients using steroids, as these medications can reduce the activity of immune processes necessary for wound healing [8]. The healing process can also be disrupted by diabetes, but preparations containing carnitine were effective in such models as well, promoting skin regeneration and faster healing [9]. Benefits of carnitine are not limited to simple wounds – larger burns were also investigated. Carnitine successfully reduced tissue necrosis, promoted cell proliferation, and increased the formation of new blood vessels [10], [11]. The positive effects on skin cells is enhanced even more when carnitine is combined with retinol (a form of vitamin A) or vitamin C [6], [10].

Carnitine exists in two forms: L-Carnitine and D-Carnitine.  Only the L-Carnitine form is desirous as the D-Carnitine form is physiologically inactive and can inhibit the uptake and functions of the natural isomer L-Carnitine. BulkActives' Carnitine is L carnitine.
