One minus

Good forSensitive Skin, Dry Skin

Both recommended for Hyperpigmentation.

#2

Best Cheaper Alternative

  • Size: 5 ml
  • Price per ml: $0.40/ml (original $1.35/ml)

The why

A lightweight 5% niacinamide serum for dark marks, uneven tone, and a quick glow. Reddit users describe fast absorption and occasional impressive fading, though others saw nothing after months or experienced worsening skin.

One minus

Does nothing for some users, even after four months

Both recommended for Hyperpigmentation.

“To treat the red/purple marks that remain for ages after you get rid of the initial pimples, i recommend the axis-y dark spot correcting serum!”

— Reddit, r/acne

#3

Best for Hyperpigmentation

  • Size: 30 ml
  • Price per ml: $4.93/ml (original $1.35/ml)

The why

A 15% L-ascorbic acid serum paired with 1% tocopherol and 0.5% ferulic acid for morning antioxidant support and visible tone work. It suits experienced vitamin-C users chasing pigmentation and glow, but sensitive skin may sting and oxidized bottles turn orange.

One minus

Mind-bogglingly expensive for 30 mL

Good forDry Skin, Sensitive Skin

Both recommended for Hyperpigmentation.

“Changes: Added CE Ferulic + tretinoin + tinted SPF”

— Reddit, r/40plusskincare

#4

Best for Brightening

  • Size: 30 ml
  • Price per ml: $0.84/ml (original $1.35/ml)

The why

A high-strength L-ascorbic acid serum paired with Alpha Tocopherol and Ferulic Acid for morning antioxidant and pigment work. It suits experienced active users chasing glow and sun-spot fading, but reactive or tret-irritated skin may burn, peel, or break out.

One minus

20% strength can burn, redden, or damage a fragile barrier

Both recommended for Hyperpigmentation.

“It completely erased my sun spots in three months.”
