My Signature Vita B5 Toner
My Signature Vita B5 Toner
Product Description
Product overview
Tia'm My Signature Vita B5 Toner is a lightweight, low-pH hydrating toner from a sister brand of COSRX, formulated with a clinical-strength 10,000 ppm (1%) of Panthenol (Pro-Vitamin B5), three peptides, hydrolyzed collagen, sodium hyaluronate, and three fermented extracts. This fragrance-free, alcohol-free, essential-oil-free K-beauty toner delivers instant moisture, strengthens a compromised skin barrier, and preps skin for serums — perfect for the 7-skin method and sensitive, dehydrated, barrier-damaged complexions.
Clinical-Dose Panthenol
A full 10,000 ppm (1%) of Pro-Vitamin B5 delivers deep hydration and calms redness at a concentration shown in studies to visibly strengthen the skin barrier.
Texture & feel
SENSORYClinical-Dose Panthenol
A full 10,000 ppm (1%) of Pro-Vitamin B5 delivers deep hydration and calms redness at a concentration shown in studies to visibly strengthen the skin barrier.
Triple Peptide Complex
Palmitoyl Pentapeptide-4 (Matrixyl) and Acetyl Hexapeptide-8 (Argireline-like) work together to soften the appearance of fine lines.
Fermented Extracts
Three Saccharomyces and Lactobacillus ferments nourish skin, boost ingredient absorption, and add a subtle glow-boosting effect.
Low pH Barrier Support
pH of 5.0–6.0 matches the skin's natural acid mantle, making it ideal prep before acids (AHA/BHA) and actives without disrupting barrier function.
Perfect for 7-Skin Method
Thin, non-tacky texture layers up to 7 times without pilling — a favorite for reviewers practicing the viral Korean hydration-layering technique.
Generous 180 ml Size
Nearly 20% larger than the standard 150 ml toner bottle and priced under $15 — among the most affordable-per-ml hydrating toners from Korea.
Safety & compatibility
SAFEContains no retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters. Panthenol and peptides are considered safe during pregnancy.
No fatty acids, esters, oils, or polysorbates. The Saccharomyces/Lactobacillus ferments are considered safe for fungal-acne-prone skin.
Every ingredient in the INCI rates 0–1 on the comedogenic scale. Very low risk of clogged pores or breakouts.
Works beautifully under vitamin C, retinol, AHAs, BHAs, and niacinamide. Actually buffers and soothes the skin when using harsh actives.
All ingredients are plant-derived or synthetic. Note: Tia'm as a brand does not hold official cruelty-free certification.
Contains Chlorphenesin (preservative) and trace Citric Acid. A small percentage of very sensitive users may experience mild tingling — patch-test first.
Ingredient breakdown
INGREDIENTSPanthenol (Pro-Vitamin B5) 1% (10,000 ppm)Proven
The hero ingredient and namesake of this toner. Panthenol is a humectant that attracts and holds water in the upper layers of skin, while also acting as an anti-inflammatory and barrier-repair agent. A clinical concentration of 1% — listed 4th on the INCI — is far higher than the token amounts used in most hydrating toners.
- Estimated concentration: 2.7–4.1% (per WhatsInMyJar ingredient modeling), well above the 2% threshold considered clinically effective.
- CIR Safety Assessment: Panthenol is rated safe as used in cosmetics at typical concentrations.
- Function: Humectant, soothing, barrier-repair, anti-inflammatory, wound-healing support.
Palmitoyl Pentapeptide-4 (Matrixyl) ~0.85–1.25%Promising
Also known as Matrixyl, this is a signal peptide that communicates with skin cells to encourage collagen synthesis. It's one of the most well-studied anti-aging peptides in cosmetic literature, and its placement as the 10th ingredient here suggests a realistic functional dose.
- Mechanism: Stimulates fibroblasts to produce collagen types I, III, and IV plus fibronectin.
- Research: In a 12-week study, 3 ppm Matrixyl reduced wrinkle depth by roughly 17%.
- Function: Anti-aging, collagen-boosting, firming, fine-line softening.
Acetyl Hexapeptide-8 (Argireline) ~0.5–1.15%Promising
Often marketed as a "topical Botox alternative," Acetyl Hexapeptide-8 is a neurotransmitter-inhibiting peptide that may reduce the depth of expression lines over time. Effects are modest and cumulative — not comparable to injectables — but it pairs well with Matrixyl for a layered anti-aging approach.
- Mechanism: Competes with SNAP-25 protein to limit catecholamine release at muscle-nerve junctions.
- Evidence: Studies show mild reduction in the appearance of forehead and eye-area lines after 4–8 weeks of regular use.
- Function: Expression-line smoothing, skin-conditioning.
Sodium Hyaluronate ~0.4–0.95%Proven
The smaller-molecular-weight salt form of hyaluronic acid. It absorbs faster and penetrates more effectively than the raw acid form, holding up to 1,000 times its weight in water and plumping the skin's surface layer from within.
- Function: Deep humectant, plumping, barrier-support.
- Skin-identical: Hyaluronic acid is naturally present in skin and loss of it is a key driver of aging.
Hydrolyzed Collagen ~1.7–2.6%Promising
Collagen cleaved into smaller, water-soluble fragments. At this size, it can't penetrate deeply to boost your own collagen, but it works beautifully as a surface film-former, giving skin an instantly smoother, more supple feel.
- Function: Humectant, skin-conditioning, film-forming.
- Note: Tiam lists this as fish-derived — this toner is not strictly pescatarian-free.
Triple Ferment Complex ~3–5% combinedPromising
Saccharomyces/Viscum Album (Mistletoe) Ferment, Saccharomyces/Imperata Cylindrica Root Ferment, and Lactobacillus/Soybean Ferment. Fermentation breaks botanicals into smaller bioavailable molecules rich in amino acids, peptides, and antioxidants that feed both skin and its microbiome.
- Viscum Album (Mistletoe): Antioxidant and anti-inflammatory polysaccharides.
- Imperata Cylindrica: Known as a long-duration hydration ingredient (sometimes called the "72-hour hydration root").
- Soybean Ferment: Rich in isoflavones and amino acids that condition the skin barrier.
Betaine & Glycerin ~3.5–5.2%Proven
Two classic, skin-identical humectants. Betaine (trimethylglycine) is an osmolyte that regulates cellular water balance, while glycerin is the gold standard of hydration — safe for nearly every skin type and a reliable workhorse moisturizer.
- Betaine: Sugar-beet-derived, supports cell-water homeostasis.
- Glycerin: Studied for decades as one of the most effective topical humectants.

Where it fits in your routine
ROUTINEApply right after cleansing on damp skin. Ideal for the 7-skin method — layer up to 7 times for a plumping hydration surge. Fits in both AM and PM routines.
How to use
HOW TO USECleanse & Pat Dry
After double-cleansing, gently pat skin with a clean towel — leave it slightly damp for better toner absorption.
Dispense & Warm
Pour a nickel-sized amount (about 2–3 ml) into your palms. Warm between hands for 2 seconds to activate the humectants.
Press Into Skin
Press and pat evenly across face and neck — do not rub. For dry patches, concentrate extra product on cheeks, forehead, and chin.
Layer (Optional)
For extra-dehydrated or winter skin, repeat 3–7 times (the 7-skin method). Wait ~10 seconds between layers for full absorption.
Lock It In
Follow immediately with your essence, serum, and moisturizer while skin is still slightly tacky to trap the hydration.

Skin type compatibility
SKIN TYPESPanthenol, glycerin, betaine, and HA deliver deep hydration — one of the most recommended Korean toners for dryness and post-menopausal skin.
Fragrance-free, alcohol-free, essential-oil-free. WhatsInMyJar rates its irritation potential as low.
Lightweight enough for the T-zone, hydrating enough for cheeks — balances both zones without imbalance.
Non-comedogenic and oil-free, but some oily-skin users find it slightly rich for summer. Works well as a lightweight AM layer.
Fungal-acne safe, non-comedogenic, and the Panthenol actively supports healing post-breakout — ideal alongside BHAs and retinol.
Two anti-aging peptides (Matrixyl & Argireline-style) plus collagen make this one of the most peptide-loaded budget toners available.

Budget-friendly alternatives (dupes)
DUPESSerum-format rather than toner, with more peptides but no Panthenol spotlight. Similar anti-aging payload; lacks ferments and low-pH acid-mantle support.
From Tiam's sister brand. Uses Panthenol, Allantoin, and HA — very similar barrier philosophy. Slightly richer feel but fewer peptides and no ferments.
Ultra-minimalist 9-ingredient formula with Astragalus root. Thicker, more essence-like. Lacks peptides and ferments but excellent for ultra-reactive skin.
Hyaluronic-acid focused with 5 molecular weights of HA. Heavier in texture, best for very dry skin. Less emphasis on Panthenol/peptides.

Frequently asked questions
FAQYes. The formula contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters — the main categories typically restricted during pregnancy and breastfeeding. The stars of this toner (Panthenol, peptides, hyaluronic acid, glycerin, and ferments) are all considered safe during both pregnancy and lactation. As always, consult your OB/GYN or dermatologist if you have concerns specific to your situation.
Yes, this toner is generally considered fungal-acne safe. It contains no fatty acids longer than 10 carbons, no fatty esters, no oils, and no polysorbates — the main ingredient categories that feed Malassezia yeast. The fermented extracts it does contain (Saccharomyces and Lactobacillus ferments) are from different fungal/bacterial strains than Malassezia and are widely tolerated by fungal-acne-prone users. As always, individual reactions vary — patch-test first.
Absolutely — in fact, it's an ideal partner for all of them. Because it has a low pH (5.0–6.0) that matches the skin's acid mantle and contains soothing Panthenol at 1%, it preps and buffers the skin before actives, reducing stinging and irritation. Apply this toner first on damp skin, wait ~30 seconds, then layer your active serum. Many users use it as a nightly "post-active calming step" on top of retinol or AHAs.
It's best-suited to dry, dehydrated, sensitive, mature, and barrier-damaged skin — this is where the 1% Panthenol and peptide complex shine. Combination and acne-prone skin also do well with it, given the fungal-acne-safe, non-comedogenic formula. Very oily skin types may find it slightly rich for summer but still appreciate it as a lightweight AM layer or under actives.
Instant hydration and redness reduction are visible within the first application — that's the Panthenol at work. Barrier improvements (less tightness, less stinging with actives) typically show by week 1–2. Texture smoothing and improved moisture retention arrive by weeks 2–3. Subtle peptide-driven firmness and fine-line softening require 8–12 weeks of consistent daily use.
Step 2 of your routine — immediately after cleansing and before essence, serum, and moisturizer. Apply to damp skin for maximum absorption. It can be used both morning and evening. For the viral "7-skin method," apply 3–7 thin layers in succession, waiting a few seconds between each.
No. Every ingredient in the 16-ingredient INCI rates 0 or 1 on the comedogenic scale, and the overall formula is rated 0/5 — the lowest possible pore-clogging risk. It is oil-free, silicone-free, and contains no butters or waxes. User reviews from acne-prone, rosacea-prone, and oily-skin communities consistently confirm no breakouts or clogged pores with regular use.
The standard PAO (Period After Opening) is 12 months, though some users and batch labels note 6 months — always check the small jar icon on your individual bottle. To preserve the peptides and ferments, store it upright in a cool, dry place away from direct sunlight, and avoid leaving it in a steamy bathroom or on a sunny windowsill. Decanting into a smaller container for daily use can extend the life of the main bottle.
Verdict: Tia'm My Signature Vita B5 Toner is one of the best-dosed, best-priced Panthenol toners in K-beauty today. Backed by a clinical 1% Panthenol concentration, three peptides, three ferments, and a supporting cast of classic humectants, it delivers barrier-repair and anti-aging performance typically found in $25–40 formulas for under $15. Its fragrance-free, low-pH, fungal-acne-safe, pregnancy-safe formula makes it one of the most universally recommendable toners available — especially for sensitive, reactive, dehydrated, or active-heavy routines. A no-brainer for anyone practicing the 7-skin method or rebuilding a compromised barrier.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
