When layering,
let each product
absorb for two or
three minutes so
it’s not counteracted
or diluted by the
next one you put on.
—Neil Sadick
Ninety percent of fine
lines are caused by
sun exposure, which
makes sunscreen the
ultimate ingredient
for younger-looking
skin. Use an SPF 30 or
higher daily. —Day
Weekly chemical
peels help healthy
bacteria grow. Gritty
scrubs have the
opposite effect,
triggering collagen-
destroying enzymes.
—Whitney Bowe
New to chemical
peels? Try glycolic
acid for normal skin,
salicylic acid for
oily or combination
skin, and gentle
lactic acid for dry or
sensitive skin. —Day
Use brighteners (we
like vitamin C) within
six months of seeing
a dark spot. Melanin
goes deeper into
skin over time, so it’s
harder to reach.
—Jessica Wu
If you’re breaking out
along your hairline, it
could be from the oil
in your hair products.
A foaming face wash
cuts through the oil
without being harsh.
—Patricia Wexler
Sheet masks push
hydrating ingredients
into the skin.
Put one on over your
moisturizer for 10
minutes at night, and
your skin will be dewy
the next day. —Day
Using retinol is a
marathon, not a
sprint. It stimulates
collagen but can
irritate. Start using it
once per week,
over a moisturizer.
—Joshua Zeichner
Layer oils over creams—
oil can penetrate moisturizers,
but not vice versa.
Salicylic acid is
really only ideal for
blackheads and
whiteheads. If it dries
you out, look for it in a
face wash (let it sit on
your skin for 30
seconds). —Zeichner
Your skin uses omega
fatty acids to produce
lipids (moisturizing
oils), and studies
show that omega-3
supplements improve
skin’s lipid levels and
hydration. —Wu
Don’t forget
sunscreen on your
ears, hairline, neck,
hands, and chest.
Dermatologists can
look at your décolleté
to see how old you
are. —Ranella Hirsch
Benzoyl peroxide kills
P. acnes bacteria; use
it all over to prevent
breakouts. A 2.5 or
5.5 percent formula
works without flaky
side effects.
—William James
If you wake up to
puffy eyes, add an
extra pillow under
your head while
you sleep—gravity
drains enough fluid to
help with next-day
puffiness. —Zeichner
Glycolic acid treats
lines and dark spots.
It’s most effective in
individually wrapped
peel pads—the pH
of glycolic acid can
change when it’s
exposed to air. —Wu
If your skin is ashy,
make one easy
change: Don’t dry it
completely before
moisturizing. Creams
seal in hydration and
work best with a little
water. —Hirsch
Treat dark spots
using antioxidants
during the day. At
night, apply
topical retinoids to
enhance cell turnover
to shed pigment.
—Zeichner
Dryness, redness,
and tight skin are
signs that you may
need to switch to a
higher SPF. Try a new
sunscreen and see if
the issues go away in
a few days. —Sadick
