Description

Cos De BAHA TN Serum is formulated around two headline actives:

Tranexamic Acid – 5%

Niacinamide – 5%.

The brand positions Tranexamic Acid primarily for:

• uneven-looking skin tone,
• dark spots,
• visible discoloration,
• and post-acne pigmentation.

Niacinamide provides complementary support by helping:

• brighten uneven-looking skin,
• strengthen the skin barrier,
• support balanced sebum production,
• and improve overall skin clarity.

The current official formula has a clear, watery texture that absorbs quickly rather than a heavy oil or cream consistency.

It also contains:

• Glycereth-26
• Betaine
• Propanediol
• Aloe Barbadensis Leaf Extract
• Sodium Hyaluronate
• Allantoin
• Green Tea Leaf Extract
• Elder Flower Extract
• Bitter Melon Fruit Extract
• Edelweiss Extract.

These supporting ingredients make the formula more than a simple two-active solution by adding hydration and soothing care.

Key Ingredients & Their Benefits

Current Official Ingredient List

Cos De BAHA’s current official product page lists:

Water/Aqua, Tranexamic Acid, Niacinamide, Glycereth-26, Betaine, Propanediol, 1,2-Hexanediol, Aloe Barbadensis Leaf Extract, Sodium Hyaluronate, Allantoin, Xanthan Gum, Citric Acid, Camellia Sinensis Leaf Extract, Sambucus Nigra Flower Extract, Momordica Charantia Fruit Extract, Leontopodium Alpinum Extract.

Important Formula-Version Note

Another Cos De BAHA commerce page still displays an older or alternate ingredient list beginning with:

Aloe Barbadensis Leaf Extract, Tranexamic Acid, Niacinamide…

rather than Water/Aqua first.

Current newer product records also show the Water/Aqua-first formula, matching Cos De BAHA’s dedicated current official page.

Therefore, Infinity Skincare Solutions should follow the ingredient panel printed on the physical TN 30ml bottle or box when publishing final inventory data.

How to Use

Cos De BAHA’s current official directions are to apply an appropriate amount after cleansing and toning and gently pat it into the skin.

Cos De BAHA specifically warns that its concentrated products may cause allergic reactions or burning in sensitive users and recommends testing a small area under the chin before regular use.

Product Specifications

Important Active Concentrations

The current official formula clearly confirms:

Tranexamic Acid – 5%

Niacinamide – 5%.

These are separate active concentrations.

Do not describe the product as:

“10% Tranexamic Acid”

or

“10% Niacinamide.”

The correct wording is:

“5% Tranexamic Acid + 5% Niacinamide.”

What Does Tranexamic Acid Do in Skincare?

Topical Tranexamic Acid is used in cosmetic brightening products to help reduce the appearance of uneven pigmentation and discoloration.

Cos De BAHA specifically positions its 5% concentration for:

• hyperpigmentation,
• dark spots,
• visible discoloration,
• uneven skin tone.

It should not be described as permanently curing melasma or medically treating every form of pigmentation.

A responsible claim is:

“Helps visibly improve dark spots and uneven-looking pigmentation with consistent use.”

Is Tranexamic Acid an Exfoliating Acid?

No.

Despite the word “acid,” Tranexamic Acid is not an AHA or BHA exfoliant.

It does not function like:

• Glycolic Acid,
• Lactic Acid,
• Mandelic Acid,
• or Salicylic Acid.

This makes TN Serum useful for customers who want pigmentation-focused care without adding another dedicated chemical exfoliant.

What Does 5% Niacinamide Do?

Cos De BAHA uses 5% Niacinamide to support:

• brighter-looking skin,
• barrier strength,
• improved skin tone,
• balanced sebum,
• and skin comfort.

Five percent is also lower than the brand’s separate 10% and 20% Niacinamide serums, making TN Serum more focused on combined pigmentation care rather than maximum-strength Niacinamide.

Does It Contain Hyaluronic Acid?

Yes.

The formula contains:

Sodium Hyaluronate

which is a salt form of Hyaluronic Acid.

Cos De BAHA describes it as providing deep hydration and supporting skin elasticity.

Does It Contain Aloe Vera?

Yes.

The current Water-first formula contains:

Aloe Barbadensis Leaf Extract.

Cos De BAHA highlights Aloe for its soothing and moisturizing role.

Does It Contain Fragrance?

The current official INCI does not list:

• Parfum
• Fragrance
• essential oils
• Limonene
• Linalool
• Citral.

Therefore, the current formula can accurately be described as having no added fragrance identified in the official ingredient list.

This is more precise than making an unsupported universal hypoallergenic claim.

Does It Contain Alcohol?

The current official ingredient list does not contain:

Alcohol Denat.

or

Ethanol.

1,2-Hexanediol is present, but this is a multifunctional humectant/preservative-support ingredient and should not be confused with drying ethanol.

Does It Contain Retinol or Exfoliating Acids?

No current official ingredient list shows:

• Retinol
• Retinal
• Adapalene
• Glycolic Acid
• Lactic Acid
• Salicylic Acid.

Citric Acid is included in the formulation, but there is no evidence that this product is designed as a dedicated AHA exfoliating serum.

Can It Be Used With Vitamin C?

Generally, yes.

Tranexamic Acid and Niacinamide can both be incorporated into routines containing Vitamin C.

For example:

AM:
Cleanser → TN Serum → Moisturizer → Sunscreen

PM:
Cleanser → Vitamin C or another compatible treatment → Moisturizer

or the order can be adjusted based on texture and tolerance.

If your skin is sensitive, introduce one active product at a time rather than layering several new products immediately.

Can It Be Used With Retinol?

There is no retinoid in TN Serum.

Tranexamic Acid and Niacinamide can generally coexist in a routine with Retinol, but users prone to irritation may prefer:

TN Serum in the morning

and

Retinol at night.

This is primarily a tolerance strategy rather than a strict incompatibility rule.

Can It Be Used With AHA/BHA?

Yes, but sensitive users should be cautious.

TN Serum itself is not a chemical exfoliant.

If using:

• Glycolic Acid,
• Lactic Acid,
• Salicylic Acid,
• or a peel

in the same routine, monitor for excessive:

• burning,
• dryness,
• redness,
• or barrier irritation.

Using the exfoliant and TN Serum at different times may be more comfortable.

Is It Good for Post-Acne Marks?

Yes, this is one of the most logical uses for the formula.

The combination of:

5% Tranexamic Acid + 5% Niacinamide

is designed to improve the appearance of uneven pigmentation and discoloration left after blemishes.

However, distinguish:

post-acne marks / discoloration

from:

indented or raised acne scars.

This serum may support color correction but will not reconstruct deep atrophic scars.

Is It Good for Melasma?

Cos De BAHA markets the product toward visible hyperpigmentation, and some brand commerce copy explicitly references the appearance of melasma.

However, melasma is a complex pigmentation disorder.

Infinity Skincare Solutions should avoid promising that TN Serum will:

“cure melasma”

or

“permanently remove melasma.”

A better description is:

“May help improve the appearance of uneven pigmentation, including stubborn discoloration, as part of a consistent sun-protected skincare routine.”

Sunscreen Is Essential for Dark-Spot Care

TN Serum has:

no SPF.

When treating:

• dark spots,
• post-acne marks,
• uneven skin tone,
• or pigmentation,

daily sunscreen is important because UV exposure can contribute to ongoing pigmentation.

A practical AM routine is:

Cleanser → TN Serum → Moisturizer → Broad-Spectrum Sunscreen.

Current Formula vs Older Aloe-First Formula

There is a live formula-list discrepancy across Cos De BAHA’s own commerce presence.

Current Dedicated Official Page

Begins with:

Water/Aqua → Tranexamic Acid → Niacinamide → Glycereth-26 → Betaine…

Older / Alternate Official Commerce Listing

Begins with:

Aloe Barbadensis Leaf Extract → Tranexamic Acid → Niacinamide → Glycereth-26… and displays an N.O.I.P. 78% notation.

Current European retail records exist with both versions as well, while newer records show the Water-first formula.

For Infinity Skincare Solutions:

the physical product ingredient panel should be the final authority.

The important headline concentrations remain:

5% Tranexamic Acid + 5% Niacinamide.

TN 5% vs Cos De BAHA TT Tranexamic Acid 10%

Cos De BAHA also sells a separate higher-strength product commonly identified as:

TT Tranexamic Acid 10% Serum.

That is not the same product as this TN Serum.

TN Serum

• Tranexamic Acid 5%
• Niacinamide 5%
• balanced brightening/barrier approach
• 30ml and 60ml formats.

TT Serum

• separate higher-strength Tranexamic Acid product
• different formula and positioning.

Customers should not confuse the two when comparing percentages.
