Medik8 is an industry leader when it comes to retinol – the brand offers a whole host of effective options. The stand-out Crystal Retinal line, however, manages to balance swift results with minimal irritation, which is no easy feat. Initially, begin using it a couple of times a week in smaller doses. As you start to see results and less irritation, you can steadily increase the percentage – but this has to be done over time (reading more on best practice retinol usage is recommended). Overuse of retinol can cause redness, sensitivity and peeling, so, do keep in mind that whilst using any product containing retinol you'll need to apply daily sunscreen. Diamond dusted surgical instruments can leave behind large superficial glistening opacities when used in vitrectomy for epiretinal membrane peel. Originally described in diamond coated silicone cannula; the Tano surgical blade was also reported to shed diamond dust on the retinal surface. The crystals are inert and cause no retinal dysfunction. Similar to our Intelligent Retinol range, we always advise phasing in the use of Crystal Retinal - using twice a week for the first 2 weeks, every other night for the next 2 weeks, and then every night.

Hyaluronic Acid – With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion feeling both nourished and supple Infantile nephropathic cystinosis is the most common (95%) and severe presenting within the first year of life with failure to thrive, growth retardation and renal tubular acidosis leading to renal failure within the first decade of life.
WHAT WE RECOMMEND WITH THIS...
Since introducing the cream into our beauty regimen, we’ve noticed fine lines plump out for a more youthful appearance, whilst the depth and volume of crow’s feet has become less noticeable. Methoxyflurane is, now rarely used, volatile inhalation anesthetic that causes dose-dependent renal tubular damage due to deposition of calcium oxalate crystals resulting in secondary hyperoxalosis. At cumulative doses >16g, calcium oxalate crystals can cause retinopathy during prolonged anesthesia (greater than 4 hours) and in situations of abuse. [56] [55] [78] Risk factors include mild renal insufficiency and hypertension in addition to exposure. [79] [80] Other causes of secondary oxalosis were discussed in the PH section. Deposition of retinal crystals are presumably due to elevated serum levels during prolonged anesthesia. Oxalate crystals have also been noted in the epicardium, bronchus, thyroid, and epididymis. [79] Crystals have been noted in pigment epithelium of the ciliary body and the inner retinal layers. [80] Intermediate nephropathic cystinosis has milder renal impairment, cornea and conjunctival crystals without retinopathy and presents at an older age. They do not develop growth retardation or renal failure. Utilising the powers of our unique double stabilisation system, Crystal Retinal was born. We protected the powerful yet fragile molecule with a crystal encapsulation, to both blanket the retinal and time-release it onto our skin gradually throughout the night to minimise any potential for irritation. We then reinforced this with a patent-pending stabilisation formula complex, which is unique to Medik8, to ensure the retinal is stabilised throughout its whole life cycle - from raw material, all the way onto our skin. This means that your Crystal Retinal remains powerful from the first application, to the very last. Multimodal imaging may support the diagnosis, primarily detecting telangiectasia manifestations rather than the crystals. [3] [56] [30] SD-OCT and AO can identify crystals within the nerve fiber layer. Foveal atrophy, cystic foveal cavitation, and foveal and parafoveal retinal thinning are not always evident on SD-OCT. [153] [154] Red free and confocal blue light photography can aid in detection of crystals. FA can reveal leakage from the telangiectasias however neither FA or ICG reveal crystalline deposits. [86] OCTA can show dilated vessels in the temporal parafoveal deep capillary plexus early in the disease course and eventual juxtafoveal capillary network with anastomoses and subretinal neovascularization with disease progression. [150] [155]
Yellow oxalate crystals are typically found in all retinal layers, though predominantly in the outer plexiform and outer nuclear layers, of the perifoveal or periarterial regions of the macula. [53] [50] [54] Intraarterial oxalate crystals are associated with secondary hyperoxaluria caused by renal failure from the following causes: methoxyflurane anesthesia, ascorbic acid supplementation, pyridoxine deficiency and ileal resection. [55] Stage 2 BCD: progressive RPE atrophy extending beyond the posterior pole with associated chorioretinal atrophy with crystals diminishing in the posterior pole but remaining mid-periphery The first sign of cystinosis is cystine deposits in the cornea and conjunctiva during the first year of life resulting in symptoms of photophobia and blepharospasm. [27] [34] [33] [35] [36] The infantile nephropathic cystinosis is the only from having fine, yellow refractile deposits throughout all the retinal layers, RPE and choroid, especially in the periphery of the posterior pole. [3] Diffuse RPE mottling is the most common posterior segment finding that results in a golden-brownish reflex. [37] Pigmentary retinopathy, when present, precedes the appearance of the corneal crystals and can be observed as early as 5 weeks of age. [35] [38] With age the retina can display bone spicule pigment migration that resembles retinitis pigmentosa. Progressive retinal degeneration causes decreased visual acuity, constricted visual fields, and decreased cone-rode function. [35] Simultaneously, when photophobia manifests patients with infantile nephropathic cystinosis will have fluid and electrolyte loss, aminoaciduria, glucosuria, phosphaturia, hypercalciuria and hypochloremic acidosis. These patients can present with growth retardation and hypothyroidism. [7] Currently, there are no FDA-approved treatments for drusen or GA. AREDS/AREDS2 showed supplementation of specific nutrients to reduce the risk of choroidal neovascular membrane formation and subsequent vision loss. [115] Red-free fundus photography is superior in visualizing crystals compared to conventional color fundus photography. [110]So the best practice is to remain patient – you won't see results instantly, but stay loyal to it and a softer and brighter complexion will soon come. Diagnosis is made by clinical history of intravitreal triamcinolone injection(s) and posterior pole exam showing large extravascular white to yellow-green iridescent crystals deposits clustered in the fovea or perifovea. Crystals can collect on the retinal surface or in the premacular bursa of the posterior hyaloid. [98] [100] Deposition of crystals along the retinal vasculature can simulate frosted-branch angiitis due to their reabsorption by perivascular macrophages. [101] Imaging includes SD-OCT reveals hyperreflective lesions within the dome-shaped RPE elevations and regions of fibrosis and atrophy. FAF shows hyperautofluorescent dots and ring-like areas of hyperautofluorescence surrounding a central hypoautofluorescent area that corresponds to crystalline deposits. [57] EDI-OCT shows the presence of hyperreflective deposits from the retina, subretinal tissue, and choroid. [58] FA reveals a ring of transmitted hyperfluorescence associated with the crystals. [53] ERG may show decreased photopic and scotopic amplitudes of a- and b-waves; other studies show no retinal toxicity on full-field and focal ERG. [56] [94] After two weeks of usage, or once skin has acclimatised to Medik8 Crystal Retinal 20, application can be increased to 2 pumps of Medik8 Crystal Retinal 20, applied in the same way as above and followed with Medik8 Advanced Night Restore.
Vitamin A and its retinoid forms stimulate skin cell renewal by increasing the rate of cell division, thereby encouraging new cell growth. This helps keep your skin soft and smooth.' Vitamin A or ‘retinoids’ is the family term for all vitamin A molecules and their derivative forms, including retinol and retinal, or derivatives like retinyl palmitate. Medik8 has a large range of vitamin A products to suit every skin type and need, and as a science-led brand, we focus all our attention on the forms of vitamin A that are clinically proven to provide great results; retinol, retinaldehyde and retinyl retinoate. THE VITAMIN PATHWAY OCT imaging shows refractile deposits on the retinal surface; no angiographic abnormality is typically apparent.Diagnosis is made when the following triad of symptoms are present: progressive nyctalopia, reduced visual acuity, and visual field loss in the third decade of life. [6] [10] Slit-lamp exam can reveal crystals in the perilimbal anterior corneal stroma. [11] On dilated fundus exam (DFE), numerous prominent small, glistening yellow-white crystals are seen scattered throughout the posterior pole extending to the midperiphery. These crystalline deposits may tend to diminish with advanced disease. The yellow-white intraretinal crystals are found at the level of RPE-choriocapillaris complex and lead to RPE pigment clumping and choriocapillaris atrophy. The classic triad of symptoms is also appreciated in diseases on spectrum of retinitis pigmentosa and should be considered in the differential diagnosis. [12] With few ocular diseases sharing common findings of the typical crystalline deposits in the cornea and retina, diagnosis can be made with high degree of certainty from clinical exam alone. [8] There are three stages described by Yuzawa et al [13]:
Unfortunately, retinol does come with some side effects, though these can be reduced by choosing the right formula for your skin type and applying it properly. You should always introduce retinol tentatively into your skincare routine at first, then build it up slowly as your skin becomes more tolerant.As goes with all active skincare, you should start slow and work your way up. Going too hard and fast with retinol use can lead to negative side effects, like flakiness and irritation. Yuzawa M, Mae Y, Matsui M. Bietti’s crystalline retinopathy.
