Sunscreen
SPF, UV filtersThe single highest-return item in any looks routine. Everything else is damage repair; this is damage prevention.
$10 – $40Tretinoin
RxRetin-A, all-trans retinoic acidThe most studied topical for photoaging and acne. Slow, unglamorous, and genuinely effective if you survive the first three months.
$10 – $60Adapalene
DifferinThe over-the-counter retinoid. Meaningfully gentler than tretinoin with most of the acne benefit — the sensible entry point.
$12 – $35GHK-Cu
copper tripeptide-1, copper peptideThe peptide with the most credible cosmetic case. Decent mechanistic work, reasonable small trials, and it is applied to the skin rather than injected.
$20 – $70Isotretinoin
RxAccutane, oral retinoidThe only drug that reliably produces long-term remission of severe acne. Serious enough that it demands a dermatologist, monitoring and genuine informed consent.
$200 – $3kMelanotan II
MT-II, tanning peptideIt genuinely tans you. It is also unapproved, unregulated, and linked to changes in moles that matter a great deal on a site about skin.
$30 – $90Azelaic Acid
Finacea, SkinorenThe quiet all-rounder — acne, rosacea and pigmentation at once, and one of the few actives considered pregnancy-compatible.
$15 – $45Topical Cosmetic Peptides
Matrixyl, palmitoyl pentapeptide-4The peptides you can actually buy in a shop. Mild, safe, and consistently oversold.
$20 – $90Benzoyl Peroxide

$8 – $30Tranexamic Acid
TXAOne of the more effective options for stubborn melasma, available topically and — under supervision — orally.
$20 – $60Hydroquinone
RxHQThe long-standing gold standard for pigmentation. Effective, but designed for defined courses rather than indefinite use.

$10 – $40

$40 – $80
Diet3
Dairy, Sugar & Acne
diet and acne, glycemic index acneOne of the few diet–appearance links with real evidence behind it. Worth testing on yourself; not worth religious adherence.
FreeOmega-3 Fatty Acids

$10 – $40Hydration
water intake, drinking waterNecessary but not magic. Being adequately hydrated matters; drinking four litres a day does not make your skin glow.
