PRODUCT DETAILS

A focused retinoid step with a lighter touch. Hyper Retinol Ex 1.0 Serum is designed to help soften the appearance of fine lines and wrinkles, pairing its visible-smoothing focus with a milky texture that feels easy to layer.

The “1.0” refers to the complete Retinol EX blend, not pure retinol alone. The formula contains 0.1% retinol, 0.3% retinyl palmitate and 0.6% bakuchiol. Niacinamide, five forms of ceramide, peptides, panthenol and allantoin round out the formula with useful supporting care.

Its lightweight, milky texture absorbs quickly without a greasy residue. That finish may be especially appealing if you have normal or oily skin and prefer lighter hydration. As a leave-on serum, it stays in your routine with that fast-absorbing, non-greasy feel.

Key Ingredients

Three open mauve, apricot and auburn grooves arc across one warm-ivory matte plaster surface beside a tiny coral point.

Retinol

May help soften the look of fine lines and uneven texture with consistent, carefully introduced leave-on use.

Translucent muted-rose abstract sculpture with flowing ridges, softly lit on a seamless warm peach surface.

Bakuchiol

A defined cosmetic ingredient with emerging formula-specific evidence for smoother-looking fine lines and more even-looking tone—not a retinoid or a pregnancy-safety shortcut.

Niacinamide

Helps visibly brighten uneven tone and support the skin barrier.

Overlapping ivory wax-like layers on a warm blush background, representing ceramide barrier lipids.

Ceramides

Barrier-supporting lipids that help reduce moisture loss and ease visible dryness.

A blush paper ribbon curves across an ivory platform with a pale lavender panel behind.

Peptides

Some exact peptide forms may support smoother, firmer-looking skin; evidence varies by peptide and formula.

Panthenol

Pro-vitamin B5 that helps skin hold moisture and feel softer and more comfortable.
