Kinky, kupi Diacneal. Ima visok odstotek retinala (0,1%), stabilen je, edina primerna embalaža za r. pa še glikolna kislina pripomore k boljši penetraciji. Z Diacnealom so na miših dobili boljše rezultate kot s tistimi na recept. Prek neta bo težko, ker zakonodaja ne dopušča uvoza zdravil na recept in nobena spletna lekarna tega ne pošilja k nam. Jaz bom tudi naslednjič kupila D., ker se mi zdi boljši.
Diacneal is a mixture of 6.4% glycolic acid (topical exfoliant) and 0.1% retinaldehyde. For an OTC product, it is a fairly powerful anti-aging/acne/hyperpigmentation treatment. The use of glycolic acid in conjunction with retinaldehyde increases the 'bioavailability' of the retinoid in the skin (ie increases the effective 'strength' of the retinaldehyde by allowing it to penetrate more deeply and efficiently and also eliciting a modest increase in the activity of the enzyme that converts retinaldehyde to the active form). Of all the avene retinaldehyde products, I would say this one packs the most 'punch' for the dollar. However, please note that diacneal is mildly fragranced, unlike some other avene retinaldehyde products.
Frčica, to je super in ugodna verzija. Edino zahteva malo več dela, ker nima dolge življenjske dobe. Približno na tri dni moraš to delat, ampak ti ne vzame več kot 5 minut. Vit. C v prahu dobiš v DM-u za manj kot 2€, glicerin pa v lekarni.

Na hitro en manjši sestavek o delovanju retinojske kisline:
Among just a *few* of the things they do: even out the complexion by interfering with excess melanin production, increase collagen production and deposition, protect collagen from degradation by down-regulating the enzymes that 'chew it up', normalize keratin production by keratinocytes so that excess keratin doesn't clog the pores (giving p acnes a nice place to grow), they are anti-inflammatory in most cases, they may be involved in DNA repair (that's right...keeps your skin young by keeping your DNA young...we may even find that they have tumor-supressor activity because of this), comedolytic (clears clogged pores you already have), they also down-regulate certain enzymes that are responsible for mediating UV-damage so that using a retinoid in the night may protect you (above and beyond what sunscreen can do) from UV damage the next day, they exfoliate the skin by increasing the rate at which new cells surface, they treat rosacea (at least retinaldehyde and differin do), etc etc etc.
No age is too young to begin using retinoids =). The medical community counsels that teens and 20s is a good age. In some instances, doctors even recommend treatment in very early life for certain ethnicities that are at high risk for UV damage accumulation at early ages (such as pale skinned red heads, etc). You can do a board search for posts by me or beethovengirl to find the exact info quoted if you'd like to know more about that =).
However, it is a commitment because you have to: 1) figure out which one is right for you and figure out what frequency works for you. This can be a tough process of trial and error because retinoids can be highly irritating when not used judiciously 2) use them continuously. The benfits go away when the drug goes away 3) use sunscreen regliously to prevent sun damage. Some retinoids thin the outermost layer of skin (stratum corneum) but they thicken and strengthen the layer underneath (epidermis). However, the stratum corneum is the first layer of protection against the sun, so thinning of this layer is going to make you more sun-sensitive.
Pa ze. : D
