TIRTIR SOS Serum – Polyglutamic Acid Hydrating Face Serum, Fragrance-Free 1.69 fl oz – Plumping & Smooth Finish

TIRTIR SOS Serum is a fragrance-free, polyglutamic-acid powered face serum that deeply hydrates, supports collagen, and delivers a dewy, smooth finish suitable for all skin types.

Designed as a daily hydration booster, this lightweight serum centers on polyglutamic acid (PGA)—a powerful humectant with superior water-retention versus hyaluronic acid—alongside soothing botanicals and a peptide to support collagen. The result is plumper-looking skin with reduced surface dryness and a subtle, healthy glow without sticky residue or added fragrance. Its gentle, vegan formula fits into both morning and evening routines and layers well under makeup to enhance a dewy complexion.

How does this serum hydrate differently from other moisturizers?

TIRTIR SOS Serum uses polyglutamic acid (PGA), which can hold several times more moisture than many standard humectants. Because PGA forms an effective moisture barrier on the skin’s surface, it helps skin stay supple longer and supports a visibly plumper texture.

• Contains high-concentration PGA for extended water retention
• Lightweight, non-greasy feel that absorbs quickly
• Helps smooth dry patches and reduce tightness
• Works well under creams or makeup without pilling

Will this serum help with firmness or anti-aging concerns?

The formula includes Acetyl Hexapeptide-8, a peptide shown to support the appearance of skin elasticity and a smoother surface. While not a replacement for professional treatments, regular use can help skin look more resilient and refined by supporting collagen-related processes.

• Peptide blend to complement collagen-supporting routines
• Targets fine lines with improved hydration and bounce
• Pairs with sunscreen and retinoids in anti-aging regimens

Is this serum suitable for sensitive or acne-prone skin?

TIRTIR formulated this serum fragrance-free and with gentle, vegan ingredients to minimize irritation. Soothing extracts like witch hazel and chamomile help calm redness and surface irritation while maintaining pore clarity when used as directed.

• Fragrance-free and non-sticky for fewer irritation triggers
• Witch hazel helps soothe and refine pores
• Chamomile provides calming antioxidant support
• Safe for daily AM and PM use for most skin types

How do I use the SOS Serum for best results?

Apply to clean, slightly damp skin to maximize moisture binding; follow with moisturizer or sunscreen in the morning. It layers smoothly under makeup and can be gently blended into base products to create a luminous, dewy finish.

• Use 2–3 drops after cleansing and toning, morning and night
• Pat gently into face and neck until absorbed
• Seal with moisturizer and daytime SPF for protection
• Blend during makeup base for a natural glow-enhancing effect

Who is this for? TIRTIR SOS Serum is ideal for anyone seeking deeper, longer-lasting hydration and a plumper-looking complexion without fragrance or heavy oils. It suits sensitive, dry, combination, and aging skin types who want a lightweight, daily serum that layers well under other skincare or makeup. If you want a straightforward, hydration-first product with supportive peptides and calming botanicals, this serum is a practical addition to both AM and PM routines.
