#2
Best for Hyperpigmentation

- Size: 30 ml
The why
A 15% L-ascorbic acid serum paired with tocopherol and ferulic acid for morning brightening and photoaging support. It suits experienced vitamin-C users chasing stubborn pigmentation, but reactive or oily skin may face stinging, tackiness, breakouts, and rapid oxidation.
One minus
15% strength stings reactive skin and can worsen redness
Good forDry Skin, Sensitive Skin
Both recommended for Hyperpigmentation; discussed alongside Geek & Gorgeous C-Glow in 19 threads.
“Changes: Added CE Ferulic + tretinoin + tinted SPF”

#3
Best for Anti-Aging

- Size: 30 ml
The why
A watery acetyl hexapeptide-8 serum for forehead, brow, and crow’s-feet expression lines, especially if Botox is off the table. Expect cosmetic, temporary smoothing rather than wrinkle reversal; inconsistent use and diminishing results frustrate some routines.
One minus
Results are temporary, not permanent wrinkle correction
Both recommended for Anti-Aging.
“I use the ordinary matrixyl and argireline under my frownies and find that the combo works really well for my fine lines.”
