Séra na riasy sa líšia predovšetkým v jednom: či obsahujú analóg prostaglandínu. Od toho závisí účinok, možné vedľajšie účinky aj to, ktoré sérum sa hodí práve vám.

Najdôležitejší rozdiel
Séra na riasy bez analógov prostaglandínov a s nimi
Bez prostaglandínov
S analógmi prostaglandínov
Princíp účinku
Peptidy, kofeín a rastlinné extrakty riasy ošetrujú a podporujú
Predlžujú rastovú fázu rias (skupina látok z liekov na glaukóm)
Efekt
Jemnejší, chce trpezlivosť
Výraznejší, doložený
Možné vedľajšie účinky
Zriedkavé, väčšinou podráždenie pri neznášanlivosti
Podráždenie očí, tmavšia koža viečok, zriedka zmena farby dúhovky
Tehotenstvo
Len po konzultácii
Nepoužívať
Ako ich spoznať
V zložení nie je žiadna z látok uvedených vpravo
Napr. Isopropyl Cloprostenate, Ethyl Tafluprostamide, Bimatoprost, Norbimatoprost, Cloprostenol Ethyl Amide
Pozor na reklamné tvrdenia: „bez hormónov“ ešte neznamená „bez prostaglandínov“. Viaceré značky sa hlásia k tomu, že sú „bez hormónov“, hoci obsahujú analóg prostaglandínu. Spoľahnúť sa dá len na zloženie.

Odporúčame – bez prostaglandínov
Lazru sérum na riasy a obočie
Jedno sérum na riasy aj obočie, bez prostaglandínov a bez hormónov. Zverejnené zloženie uvádza účinné látky Procapil™ a AnaGain™, k tomu kofeín, ženšen, biotín a kyselinu hyalurónovú. Znášanlivosť s pokožkou ohodnotil Dermatest známkou „veľmi dobrá“ (06/2022). Podľa výrobcu sa prvé zmeny ukážu po niekoľkých týždňoch, výraznejšie po dvoch až štyroch mesiacoch – u každého inak.

Bez analógov prostaglandínov a bez hormónov – zloženie je verejné
Jedno z najznámejších sér na svete. Výrobca sám označuje účinnú látku ako analóg prostaglandínu (Cloprostenol Ethyl Amide). Účinkuje výrazne – s typickými možnými vedľajšími účinkami tejto skupiny. Viac v našej recenzii RevitaLash.
V nemeckých drogériách rozšírené a často vyhľadávané. Podľa zloženia obsahuje Ethyl Tafluprostamide, analóg prostaglandínu. Výrazný účinok je možný, platia však rovnaké upozornenia ako pri všetkých sérach tejto skupiny.
Od rakúskej značky, ktorú poznáte zo štúdií na farbenie rias a obočia. Sérum stavia na peptidoch, biotíne a rastlinných extraktoch a zaobíde sa bez analógov prostaglandínov. Hodí sa na riasy aj obočie.

Údaje výrobcu o účinku vychádzajú z vlastných testov používateľov
Známe sérum z internetového predaja. Podľa zloženia s Ethyl Tafluprostamide, analógom prostaglandínu – výrazný efekt je možný, s typickými upozorneniami tejto skupiny.
Podľa výrobcu bez analógov prostaglandínov, s extraktmi z kôry magnólie, klíčkov fazule mungo a ďateliny lúčnej. Jemná ošetrujúca možnosť pre riasy aj obočie.
Známe sérum s vzorcom FX5. Zloženie v e-shope výrobcu uvádza Bimatoprost, analóg prostaglandínu. Všetko o zložení a vedľajších účinkoch nájdete v našej recenzii Long4Lashes.
Skontrolujte v zložení (INCI), či neobsahuje analógy prostaglandínov. Seriózni výrobcovia zverejňujú celý zoznam.
Znášanlivosť
Pri očiach platí znášanlivosť dvojnásobne. Dermatologický test znášanlivosti s pokožkou je plus – účinok však nedokazuje.
Očakávania
Riasy rastú v cykloch, ktoré trvajú niekoľko týždňov. Seriózni výrobcovia hovoria o mesiacoch, nie o dňoch. Sľuby typu „za 15 dní dvakrát dlhšie“ sú varovným signálom.
Nanášanie
Jemný štetček ako pri očných linkách uľahčuje presné nanesenie na líniu rias.
Riasy aj obočie
Niektoré séra sú určené na oboje. Ak vám preriedlo aj obočie, ušetríte druhý produkt.
Záleží na tom, čo ste ochotní podstúpiť. Najvýraznejšie účinkujú séra s analógmi prostaglandínov – s možnými vedľajšími účinkami. Na šetrnú starostlivosť bez prostaglandínov odporúčame Lazru.
Fungujú séra na riasy naozaj?
Séra s analógmi prostaglandínov majú doložený vplyv na rast rias. Pri sérach bez týchto látok vychádzajú údaje väčšinou zo štúdií výrobcov účinných látok alebo z testov používateľov; účinok je jemnejší a u každého iný.
Ako dlho trvá, kým sérum na riasy zaberie?
Počítajte s niekoľkými týždňami až mesiacmi. Výrobcovia serióznych sér uvádzajú prvé zmeny po niekoľkých týždňoch a výraznejšie po dvoch až štyroch mesiacoch.
Sú séra na riasy bezpečné?
Séra s analógmi prostaglandínov ohodnotil vedecký výbor EÚ (SCCS) v roku 2026 ako nebezpečné v kozmetike; právne obmedzenie zatiaľ neplatí. Séra bez týchto látok sa považujú za znášanlivejšie. Pri ochoreniach očí a v tehotenstve sa vopred poraďte s lekárom.
Môžem sérum na riasy použiť aj na obočie?
Len ak to výrobca tak určuje. Lazru a RefectoCil Lash & Brow Booster sú určené na riasy aj obočie.
