Retinol Rules: How To Use Retinol Safely With Perfec-Tone
The Retinol Rules.
Simple, strict, non-negotiable. Follow these and retinol works. Break them and it doesn't.
The core rules — memorise these
01
Never layer two retinoids within 24 hours
If you're on prescription tretinoin, do not use any Perfec-Tone retinol product on the same night. Two retinoids in 24 hours = guaranteed irritation.
02
Tretinoin nights = tretinoin + plain moisturizer only
On tretinoin nights, use only tretinoin and a plain non-comedogenic moisturizer. Nothing active. Nothing extra.
03
Non-tret nights = one Perfec-Tone retinol product only
On nights without tretinoin, use one Perfec-Tone retinol product. Not two. Not stacked with an acid.
04
SPF 30+ every morning — no exceptions
Retinol makes skin photosensitive. Without SPF every morning, you're undoing the treatment and risking worsening hyperpigmentation.
05
Peeling and purging are expected. Burning is not.
Mild flaking and initial purging (weeks 1–3) are completely normal. Persistent burning or open skin is not. Wash it off, contact us.
06
Start slow — every other night for 2 weeks
Begin every other night. If skin tolerates it well, move to nightly. Pushing too fast causes setbacks that reset your progress.
Retinol and melanin-rich skin
Retinol works exceptionally well on melanin-rich skin — but only when used correctly. PIH means any irritation can leave a dark mark. The rules above exist to prevent that, not slow you down.

Perfec-Tone retinol products — specific rules
RC
Resurfacing Crème
Nighttime use only. Start 2x per week. Do not layer with acids or vitamin C on the same night. Expect mild tingling and some peeling in weeks 1–3 — this is normal. Pair with SPF 30+ every morning.
RF
Refining Crème
Can be used nightly once skin is acclimated. If you're new to retinol, start every other night for 2 weeks then move to nightly. Do not use same night as Resurfacing Crème.
RS
Revitalizing Serum
PM use only. Start 2–3x per week. Pairs well with the Refining Crème on non-tret nights, but use one or the other — not both on the same application.
