phytosphingosine. Long-chain, complex fatty alcohol that functions as a water-binding agent and also has preservative qualities. Its name is derived from the term sphingoid, coined in 1884 by chemist J. L. W. Thudichum because the way the molecules of this substance lined up reminded him of the riddle of the Sphinx. Research shows it is effective in regulating damaged or diseased epithelial cells. It seems this ingredient can also be a cell-communicating ingredient, albeit one that is best for compromised skin (Source: Journal of Investigative Dermatology, October 2003, pages 11351137).
vitaminas PP dar vadinamas nikotino rūgštimi:
niacinamide. Also called vitamin B3, niacin, and nicotinic acid, this water-soluble ingredient is stable in the presence of heat and light. Topical application of niacinamide has been shown to increase ceramide and free fatty acid levels in skin, prevent skin from losing water content, and stimulate microcirculation in the dermis (Sources: British Journal of Dermatology, September 2000, pages 524531; and Journal of Cosmetic Dermatology, April 2004, page 88). One small study showed that 2% niacinamide was more effective than petrolatum (Vaseline) at reducing water loss from skin and increasing its hydration levels (Source: International Journal of Dermatology, March 2005, pages 197202). Procter & Gamble, whose Olay skin-care line sells several products with niacinamide, published a double-blind study involving 50 women. The subjects used a product containing 5% niacinamide (whether that amount is included in Olays niacinamide products was not mentioned) for a period of 12 weeks. Results included an improvement in the appearance of wrinkles, a decrease in skin discolorations, less redness, a reduction in sallowness, and improved elasticity (Source: Dermatologic Surgery, July 2005, pages 860865). Another study seconded P&Gs findings that niacinamide is a helpful ingredient for addressing skin discolorations. It appears that topical niacinamide has an inhibitory effect on the transfer of melanosomes to skin cells, thus it interrupts the process that causes irregular pigmentation to form (Source: Experimental Dermatology, July 2005, pages 498508).
Kaip matome, jūsų įvardintos medžiagos nieko bendra su aknės gydymu neturi ir AHA pakeisti gali net nesvajoti. Tai nežinau, ar pati čia tuos ingredientus atrinkot nežinodama ką jie daro, ar kažkas jums prikabino makaronus ir dabar bandot kabint mums

O dėl rūgščių, tai aš jas naudoju kiaurus metus, kaip ir dienai kremą su SPF
