Good Molecules Discoloration Correcting Serum (30ml) 1. Description

This is a brightening serum from Good Molecules formulated to fade skin discoloration and even out skin tone.

It combines cetyl tranexamate mesylate (a skin-friendly form of tranexamic acid) with 4% niacinamide to target hyperpigmentation, acne scars, age spots, and sun damage.

The formula is vegan, cruelty-free, fragrance-free, and designed for daily use.

According to Good Molecules, its pH is about 5.5.

2. Format

Size / Volume: 30 ml / 1 fl oz.

Texture: Lightweight, fluid serum (some users describe a slightly soapy feel that disappears when rubbed in).

Packaging: Usually in a dropper-style bottle (standard for serums).

3. Wears & Suggestions (Usage)

When to Use: Morning and night. Good Molecules recommends daily use.

How to Apply:

Use on clean, slightly damp skin. Several users say applying when skin is still a little damp helps with absorption.

Put a few drops (2–4) on your face and neck, then tap or gently massage in until absorbed.

Follow with your moisturizer or oils. In the morning, finish with sunscreen.

Skin Types: According to the brand and retailers, it’s suitable for all skin types, including oily, dry, sensitive, and acne-prone skin.

4. Key Ingredients & How They Work

Cetyl Tranexamate Mesylate (Tranexamic Acid) (~2-3% depending on source): Helps correct spots, age-related discoloration, sun damage, and stubborn pigmentation.

4% Niacinamide (Vitamin B3): Improves uneven skin texture, reduces dullness, and helps minimize the look of enlarged pores.

Humectants: Water, glycerin, propanediol — help hydrate the skin and make the formula lightweight and easy to layer.

5. Helpful Tips

Patch Test First: Because of active ingredients like tranexamic acid + niacinamide, test on a small skin patch (behind ear or jaw) for a few days.

Introduce Slowly: If you’re new to active brightening serums, start with once a day, and if well tolerated, move to twice daily.

Use Sunscreen Religiously: When using brightening serums, especially ones targeting hyperpigmentation, a broad-spectrum SPF is very important to prevent further pigmentation.

Layer Wisely:

After the serum, follow with a moisturizer or facial oil; don’t skip that step.

Be cautious mixing with very strong acids (like high-percentage AHAs/BHAs) or potent retinoids — some users report irritation or “pilling” when layering too many actives.

Be Patient: Improving discoloration takes time — consistent use for several weeks (often 8–12 weeks or more) is usually needed to see noticeable fading.

Monitor for Irritation: If you notice persistent redness, stinging, or bumps, reduce usage or pause and reintroduce slowly.

6. Real-User Feedback / Sensory Notes

Some users describe the serum as “liquid gold” for their hyperpigmentation.

Others note a “soapy consistency” when applying, which goes away if tapped into the skin and not rubbed too hard.

A few users with sensitive skin or who are using retinoids said they applied the discoloration serum before their retinoid at night.

But not everyone saw dramatic results quickly — one said they didn’t notice major change, though it “helps keep up results” when used between more aggressive treatments.

Bottom Line

The Good Molecules Discoloration Correcting Serum is a very good, affordable option for targeting hyperpigmentation, dark spots, and uneven skin tone. Its formulation strikes a balance — powerful but relatively gentle — making it usable daily. With consistent use and proper sun protection, many people see a gradual improvement in discoloration.
