The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other anti-aging skincare: serums, night creams, facial peels, wrinkle patches and anti-aging devices we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
Tirtir has built real momentum in the K-beauty market, and this serum's numbers reflect that clearly. Over 20,000 units sold in a single month is a remarkable volume figure for any serum in this category, and the 4.8-star average from 62 reviews suggests buyers are genuinely satisfied rather than simply purchasing out of curiosity.
The formula is built around hyaluronic acid, a well-studied humectant that draws moisture into the skin and may help with the appearance of plumpness and the look of fine lines associated with dehydration. The listed benefits include anti-wrinkle, brightening, and redness reduction, targeting multiple visible concerns in one product. The 50 ml size at $29 works out to a competitive cost per ml for a serum with confirmed actives.
It is suitable for all skin types and is intended for use after cleansing and before makeup, fitting naturally into both morning and evening routines. No fragrance or alcohol status is confirmed in the spec data, which is worth checking if you have sensitive or reactive skin.

Performance notes
Hyaluronic acid is the confirmed key ingredient. It is a well-established humectant that attracts and retains water in the skin, supporting the appearance of hydration, plumpness, and reduced visibility of fine lines caused by dryness. The listed benefits include anti-wrinkle, brightening, and redness removal. Brightening and redness support are not typically attributed to hyaluronic acid alone, suggesting the formula likely contains additional ingredients not disclosed in the spec listing. Buyers targeting those specific benefits should confirm the full ingredient list.
What buyers say
The gap between 20,000 monthly purchases and only 62 written reviews is notable and suggests this product is being heavily repurchased or gifted without buyers leaving written feedback. Among those who did leave a rating, 4.8 stars is exceptional. This pattern is common with viral K-beauty products that spread through social media before review volume catches up. The high purchase rate is arguably a stronger demand signal than the review count alone.

Frequently asked questions
Why does this serum have so many monthly sales but so few reviews?
A mismatch between high purchase volume and low review count often happens when a product goes viral through social media, word of mouth, or influencer coverage. Buyers purchase quickly based on recommendations rather than written reviews, and review volume catches up over time. For Tirtir, the 4.8-star average among those who did review is a positive signal, and the 20,000 monthly purchases suggest strong repeat or referral-driven demand.
What does hyaluronic acid actually do in a serum?
Hyaluronic acid is a humectant, meaning it draws water molecules toward the skin's surface and helps retain them there. This can support the appearance of hydrated, plumper-looking skin and may help reduce the visible effect of fine lines that are caused by dehydration rather than structural changes. It is generally well tolerated across skin types, including sensitive skin, and works well layered under moisturizer.
Can this serum be used as part of a morning routine?
Yes. The spec data explicitly lists 'after cleansing, before makeup' as a usage context, which fits a morning routine. Hyaluronic acid works well in both AM and PM use. If using in the morning, follow with an SPF moisturizer, as serums alone do not provide sun protection and UV exposure is a primary factor in visible skin aging.
