Everything about GLASS EFFECT, our face and neck sheet mask set — how it works, how to apply it, and what to know about ingredients and compatibility.

<h2 id="what-is-glass-effect">What is GLASS EFFECT?</h2><p>Your skin&apos;s reset button. GLASS EFFECT is CLEARSTEM&apos;s face and neck sheet mask set. It&apos;s formulated to deliver instant hydration, visible soothing, and that coveted glass-skin plump look, without a single pore-clogging ingredient.</p><p>Many hydrating sheet masks rely on heavy, pore-clogging ingredients to create that plump feeling, which can trigger breakouts for acne-prone skin. GLASS EFFECT delivers all of the juicy hydration through 8 forms of Hyaluronic Acid and Bakuchiol, with Allantoin to soothe and calm. Zero compromise.</p><p>Each box contains 3 individually packaged face masks and 3 neck masks, because neck skin is delicate and often the most neglected.</p><h2 id="how-do-i-use-it">How do I use it?</h2><ul><li>Remove the mask from the sachet and apply to clean, dry skin with the jelly side facing down. &quot;ME TIME&quot; will appear reversed when viewed in the mirror, that means it&apos;s on correctly.</li><li>Leave on for 15 to 25 minutes.</li><li>Gently remove the mask and massage any remaining serum essence into the skin. No rinsing needed.</li><li>Apply your regular skincare routine on top afterward.</li><li>Use the face mask on your face and neck mask on your neck. Any remaining serum from either mask can be pressed into the decolletage and hands.</li><li>Use anytime, day or night, whenever skin feels dry or dull. Do not use it on any area currently affected by an active skin condition.</li></ul><h2 id="when-should-i-use-it-in-my-routine">When should I use it in my routine?</h2><p>GLASS EFFECT can be used as often as you like. Apply on clean, dry skin before your regular skincare routine or before makeup application. It preps and primes the skin beautifully. There is no ramp up schedule needed.</p><h2 id="what-makes-glass-effect-different-from-other-sheet-masks">What makes GLASS EFFECT different from other sheet masks?</h2><ul><li><strong>8 forms of Hyaluronic Acid:</strong> multi weight hydration for plump, dewy looking skin.</li><li><strong>No pore-clogging ingredients, ever:</strong> many sheet masks are off limits for acne-prone skin. GLASS EFFECT is made for it.</li><li><strong>Includes a neck mask:</strong> most sheet masks only cover the face. Neck skin is delicate and deserves the same care.</li><li><strong>Bakuchiol:</strong> the plant based retinol alternative, included for its gentle profile.</li><li><strong>Cooling effect:</strong> instantly refreshes the feel of overheated, stressed skin.</li></ul><h2 id="what-are-the-8-forms-of-hyaluronic-acid">What are the 8 forms of Hyaluronic Acid?</h2><p>GLASS EFFECT contains: Sodium Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Acetylated Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, and Potassium Hyaluronate. These forms vary in molecular weight, delivering multi weight hydration that leaves skin looking plump and dewy.</p><h2 id="is-it-safe-for-blemish-prone-skin">Is it safe for blemish-prone skin?</h2><p>Yes. GLASS EFFECT was specifically designed with acne-prone and congestion-prone skin in mind, and it&apos;s formulated without any pore-clogging ingredients. Breaking out right now? It&apos;s still a gentle way to hydrate and comfort your skin.</p><h2 id="is-there-a-fragrance">Is there a fragrance?</h2><p>No added fragrance. The masks contain Blueberry Fruit and other botanical extracts, which give them a slight, natural, pleasant aroma, not a synthetic fragrance.</p><h2 id="can-i-use-it-with-prescription-products-or-acids">Can I use it with prescription products or acids?</h2><p>Yes. Use GLASS EFFECT before applying acids. It&apos;s a great prep step that sets the skin up with hydration before your actives go on. If you use a prescription product, check with your dermatologist first.</p><h2 id="is-it-safe-while-pregnant">Is it safe while pregnant?</h2><p>We recommend consulting your doctor about your current skincare products before making any changes during pregnancy or while breastfeeding.</p><h2 id="frequently-asked-questions">Frequently Asked Questions</h2><p><strong>Is it gluten-free?</strong> Yes.</p><p><strong>Does it contain nuts?</strong> No.</p><p><strong>Is the packaging BPA-free?</strong> Yes, confirmed BPA-free.</p><p><strong>Is it recyclable?</strong> The fabric is a single use product and is difficult to recycle. Check your local guidelines to see whether the outer packaging can be recycled where you live.</p><p><strong>How long does it last once opened?</strong> Use immediately after opening the sachet. The mask can dry out if left open.</p><p><strong>Is it vegan?</strong> Yes! Completely vegan.</p><p><em>*Individual results may vary. For external use only. Discontinue use if irritation occurs and consult a healthcare professional.</em></p>
