TIRTIR's SOS Serum is a fast-absorbing, deeply hydrating serum designed to rescue skin that feels dehydrated, dull, weakened, or lacking glow. Ideal for days when your complexion looks tired or your skin barrier feels compromised, this rich yet lightweight formula delivers an instant moisture boost to restore a smoother, healthier-looking finish. At the core of the serum is Polyglutamic Acid (PGA), a powerful humectant known for its ability to hold even more moisture than hyaluronic acid, helping draw hydration into the skin and keep it locked in for long-lasting comfort. This makes it especially effective for skin that feels tight, rough, or dry from weather changes, over-exfoliation, or daily stress.

As the serum absorbs quickly, it helps visibly plump the skin, making fine lines and dehydration creases appear softer and less noticeable. The result is skin that looks fresher, more elastic, and more radiant, perfect for achieving that bouncy, glass-skin glow. Because it penetrates deeply without leaving a sticky residue, it layers beautifully under moisturizers and sunscreen and also works well as a hydrating base under makeup for smoother application and reduced patchiness.

The TIRTIR SOS Serum is suitable for all skin types, but it’s especially beneficial for dry, sensitive, or barrier-weakened skin, as well as anyone experiencing temporary dehydration or loss of glow. Use it morning and night after toner, then follow with a moisturizer to seal in hydration. With consistent use, skin feels more resilient, looks more supple, and maintains a healthy, hydrated glow throughout the day.
