However, the formula does include a trace amount of salicylic acid (used as a preservative\/pH adjuster at well below exfoliant concentration). Most dermatologists consider topical salicylic acid at preservative levels safe, but some OB-GYNs prefer to avoid all salicylic acid during pregnancy as a precaution. We recommend confirming with your healthcare provider before use. The marine actives, amino acids, glycerin, and algae extracts are all considered safe in pregnancy.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq2\"\u003e\n\u003clabel for=\"faq2\"\u003eIs The Ordinary Marine Hyaluronics fungal acne (malassezia) safe?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eNo. Marine Hyaluronics is NOT considered fungal acne safe. The formula contains Polysorbate 20, an emulsifier that is known to feed Malassezia yeast — the organism responsible for pityrosporum folliculitis (fungal acne). If you have confirmed fungal acne, you should avoid this serum and consider alternatives such as The Ordinary Hyaluronic Acid 2% + B5, which contains a Polysorbate-20-free formula, or Good Molecules Hyaluronic Acid Serum. The trace salicylic acid in the formula is at far too low a concentration to counterbalance the Polysorbate 20 concern.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq3\"\u003e\n\u003clabel for=\"faq3\"\u003eCan I use Marine Hyaluronics with retinol, vitamin C, or AHA\/BHA?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eYes — Marine Hyaluronics is highly compatible with all of these actives and this is actually one of the serum's biggest strengths. Apply Marine Hyaluronics to clean, damp skin first, allow it to absorb (it absorbs within seconds), then apply your vitamin C, niacinamide, retinol, or AHA\/BHA serum on top. For retinol in particular, applying Marine Hyaluronics first as a hydrating base helps buffer dryness and irritation that retinoids can cause. The only product conflict noted by The Ordinary is with their 100% Niacinamide Powder (not standard niacinamide serums).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq4\"\u003e\n\u003clabel for=\"faq4\"\u003eWhat skin type is Marine Hyaluronics best for?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eMarine Hyaluronics is best suited for oily, combination, and dehydrated skin types. Its ultra-lightweight, zero-tacky texture makes it ideal for oily skin that needs hydration without greasiness, and for combination skin where some zones are oily and others are tight or flaky. It works well for any skin type experiencing dehydration (lack of water, distinct from dryness\/lack of oil). Sensitive skin types generally tolerate it very well given the fragrance-free, essential-oil-free formula. Those with severely dry (alipidic) skin may find it insufficient as a standalone hydrator and should layer it under a richer moisturizer or oil.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq5\"\u003e\n\u003clabel for=\"faq5\"\u003eHow long until I see results from Marine Hyaluronics?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eYou will notice an immediate effect from the very first application — skin feels softer, more supple, and less tight within minutes. This is due to the marine polysaccharides forming an instant moisture film. For lasting structural changes (reduced dehydration lines, improved overall glow and plumpness), consistent twice-daily use for 2–4 weeks produces visible results that most users notice. After 4–8 weeks, approximately 64% of users in the Deciem community report a visible improvement in skin hydration and appearance. For best results, apply to damp skin and always seal with a moisturizer.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq6\"\u003e\n\u003clabel for=\"faq6\"\u003eWhere does Marine Hyaluronics go in my skincare routine?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eMarine Hyaluronics goes in the early-to-middle treatment step of your routine: after cleansing and toning, and before heavier actives, eye cream, moisturizer, oil, and SPF. The \"lightest to heaviest\" layering principle places this serum — being water-thin — as one of the very first serums applied. A typical order: Cleanser → Toner → Marine Hyaluronics → Vitamin C or Niacinamide → Retinol (PM) → Moisturizer → Sunscreen (AM). The Ordinary recommends applying it in the \"Treat\" stage of their morning and evening regimens, specifically before creams and heavier treatments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq7\"\u003e\n\u003clabel for=\"faq7\"\u003eIs Marine Hyaluronics comedogenic \/ will it clog pores?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eNo — Marine Hyaluronics has a comedogenic rating of 1\/5, making it effectively non-comedogenic. The formula contains no oils, no waxes, and no fatty acids that could clog pores. All primary active ingredients (marine polysaccharides, amino acids, glycerin, PCA, sodium PCA, sodium lactate) score 0\/5 on the comedogenic scale. The formula is fully oil-free and has been used successfully by thousands of acne-prone users without triggering breakouts. Note that if you have fungal acne, the Polysorbate 20 may be problematic, but this is a fungal (not bacterial) acne concern, distinct from comedogenicity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq8\"\u003e\n\u003clabel for=\"faq8\"\u003eHow long does Marine Hyaluronics last after opening?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eMarine Hyaluronics has a PAO (Period After Opening) of 12 months, meaning the formula remains effective and stable for 12 months once the seal is broken. With twice-daily use of 3–5 drops per application, one 30ml bottle typically lasts 3–4 months — well within the PAO window. If used once daily or with fewer drops, it can stretch to 5–6 months.

At under $11 for a 23%-active formula combining Antarctic marine exopolysaccharides, Hawaiian red algae, micro-filtered blue-green algae, and eleven skin-identical NMF amino acids, it delivers a compelling, science-backed alternative to hyaluronic acid — particularly for oily, combination, and dehydrated skin types who find standard HA serums too tacky or heavy. The zero-pilling, water-thin texture makes it uniquely suitable for multi-step routines and actives stacking. The primary drawbacks are the difficult-to-apply watery formula, the Polysorbate 20 that excludes fungal-acne sufferers, and the 30ml bottle that some users find too small. For those without fungal acne concerns, this is a near-essential addition to any skin-type routine at an unbeatable price-to-performance ratio.\n\u003c\/p\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\n\n\n\n  \u003cbutton class=\"pp-back-to-top\" aria-label=\"Back to top\" type=\"button\" style=\"position:fixed;bottom:24px;right:24px;width:44px;height:44px;border-radius:50%;background:var(--pp-accent);color:#fff;border:none;display:none;cursor:pointer;z-index:50;box-shadow:0 4px 16px rgba(13,31,45,0.2)\"\u003e↑\u003c\/button\u003e\n  \u003cscript\u003e\n  (function () {\n    var btt = document.querySelector('.pp-back-to-top');\n    if (!btt) return;\n    var ticking = false;\n    function onScroll () {\n      if (!ticking) {\n        requestAnimationFrame(function () {\n          btt.style.display = window.scrollY \u003e 600 ?
