2. Format

Size: 30 ml. Many listings show 30 ml for Nigeria, global stock.

Form: Serum/ampoule style treated product — lightweight liquid/gel texture typically. E.g., one listing: “lightweight texture that absorbs effortlessly into the skin.”

Usage frequency: Intended as a treatment serum, used after cleansing/toning and before moisturizer/SPF (morning) or before night cream.

3. Actives & Sensory Profile

Key Actives & Concentration:

Kojic Acid 1% (≈10,000 ppm) — main brightening agent.

Niacinamide 10% — supports skin barrier, brightening, oil control.

Tranexamic Acid 2% — targets stubborn pigmentation and melasma.

Supporting ingredients: peptides (Hexapeptide-9, etc), glutathione, tocopherol, botanical extracts.

Texture & Feel:

Described as lightweight and rapidly absorbed: one listing “lightweight texture that absorbs effortlessly into the skin.”

Some user commentary:

“I was only half way through the bottle… It’s okay, hydrating and a small glow but don’t notice much difference in PIH especially in more stubborn areas.”

“The niacinamide is too high for me … I only finished one bottle and then moved on…”

Considerations (for Lagos climate):

Because of active brightening ingredients, the skin may become more sensitive to sun — hence strong emphasis on SPF.

In hot/humid climate: lightweight formatting helps, but pigmentation treatments may need consistent use since sun/heat accelerate pigment formation.

With 10% niacinamide + peptides + kojic acid, layering sensibly is important — avoid layering too many strong actives in one go to avoid irritation especially in humid skin.

4. Use & Suggestions (How to Use & Who It Suits)

Who it suits:

Those with dark spots, post‐acne marks, uneven skin tone, sun/hyperpigmentation issues.

Skin types: Normal, oily/combination, even some sensitive if introduced slowly (the product lists “formulated for all skin types including sensitive”).

Especially suitable if you live in sun-intense region (like Lagos) and want to invest in a brightening serum with multiple actives.

How to integrate:

After cleansing and toning: apply “a small amount” (2-3 drops) of the serum to face (and neck if desired). One listing says: “apply 3-4 drops … massage gently until absorption.”

Follow with your moisturizer; in the morning always follow with broad-spectrum sunscreen (essential).

At night, you can pair with light moisturizer; if you already use a retinol/strong exfoliant, consider alternation to minimise irritation.

Start slowly: if new to brightening actives, use every other night for first week or two, then increase to nightly if skin tolerates.

Because the serum includes kojic acid, niacinamide, tranexamic acid — strong set of actives — watch for any irritation, especially around sun or if your skin barrier is weak.

Pairing & layering tips:

Use this serum on its own or followed by a gentle hydrating/soothing moisturizer (important especially in hot/humid climates to maintain barrier).

Avoid layering other strong brightening/acid treatments (e.g., high % AHAs, other potent serums) on the same night unless you know your skin tolerates.

Use sunscreen every day; especially in Lagos where UVA/UVB exposure is high. Even with treatment, without sun protection pigment will recur.

If your skin becomes sensitive or you notice redness after use, reduce frequency or alternate nights.

5. Helpful Tips & Considerations

Buying & Price Info (Nigeria):

Nigerian retailers list price around: ₦13,400 → ₦20,950 for 30 ml. Example: 24Eleven lists ₦13,400 for 30 ml version.
24eleven Beauty Store

Another listing: ₦18,300 for 30 ml.

When purchasing: ensure the packaging shows “B-Boost 1% Kojic Acid Serum 30ml”, check batch/expiry date and seller reliability.

For heat/humidity shipping: ensure seller ships quickly and product is stored properly (avoid sun/heat exposure which may degrade formula).

Storage & Maintenance:

Store in a cool, dry place away from direct sunlight. In Lagos/Ifako where temperatures can be high, avoid leaving bottle in car/near window.

Ensure dropper/pump is clean to avoid contamination (important for active serums).

Use within the recommended period after opening (check symbol – e.g., “12M” for 12 months) to ensure actives are still effective.

Potential Issues / What to Watch:

Sun sensitivity: Brightening serums (kojic acid, tranexamic acid) may increase sun sensitivity; failing to use SPF may cause pigment rebound.

Irritation risk: Although formulated for all skin types, some users have reported irritation or sensory issues:

“Too greasy, doesn’t work.”

Stacking actives: Because it contains 10% niacinamide plus kojic acid + peptides, if you already use other high-strength serums you might overload — monitor your skin.

Results timeline: Brightening and fade of melanin takes time; user review: “I only finished one bottle … don’t notice much difference in PIH especially in more stubborn areas.”

What to Expect vs Reality:

You can expect improved tone, gradual fade of dark spots, smoother complexion if used consistently plus good sun protection.

However, avoid expecting overnight miracles — marks from sun/acne may need weeks to months of consistent use.

Because of the mix of actives, good value compared to using multiple serums separately.

✅ Summary

If you’re looking for a potent multi-active brightening serum—targeting dark spots, uneven tone, and wanting more than just “basic hydration”—the NINE LESS B-Boost 1% Kojic Acid Serum (30 ml) is a solid option.
