The Evening Wind-Down: A Restorative PM Routine
Night is when skin repairs itself. A considered PM routine leans into retinoids, recovery and barrier rebuild, and the layering logic matters as much as the ingredients. A senior guide to the evening wind-down.
Why night matters
Skin follows a circadian rhythm. Overnight, cell turnover peaks, repair processes accelerate, and transepidermal water loss rises, making the skin both more receptive to active treatment and more vulnerable to dehydration. A PM routine should lean into repair, not repeat the morning's defence brief.
Step 1: Double cleanse
If you wore SPF (and you did), a single cleanse is rarely enough. First, an oil or balm cleanser dissolves SPF, sebum and the day's accumulation; second, a gentle water-based cleanser cleans the skin itself. This is not indulgence, it is preparation, ensuring actives that follow reach the skin rather than a residue.
Step 2: Treat
This is the evening's core step. Retinoids, exfoliating acids or targeted treatments go here, applied to dry skin. The golden rule: do not stack retinoids and acids in the same evening. Alternate nights, 'retinoid one evening, acid the next', to maximise efficacy while protecting the barrier.
Step 3: Hydrate and buffer
A lightweight humectant serum (hyaluronic acid, glycerin) applied to damp skin adds the water retinoids and acids can deplete. For reactive skin, this is also the buffering layer that makes strong actives tolerable.
Step 4: Seal and rebuild
A ceramide-rich moisturiser is the final step and the most important overnight. Ceramides, cholesterol and fatty acids in a ~3:1:1 ratio rebuild the lipid barrier, lock in hydration, and let the actives work without compromising the skin's defences.
The sandwich, for sensitive skin
Moisturiser → retinoid → moisturiser. This slows retinoid penetration, reduces erythema and flaking, and preserves efficacy. It is not a compromise for weak skin, it is good practice for any skin building tolerance.
FAQ
Frequently Asked Questions
Do I really need to double cleanse?+
If you wore SPF, yes. SPF is designed to adhere, and a single water-based cleanser often leaves residue that blocks actives from penetrating. An oil or balm first step dissolves SPF and sebum; a second gentle cleanser cleans the skin. Without SPF, a single thorough cleanse is fine.
Can I use retinol and acids on the same night?+
Generally no. Both are strong actives and layering them overwhelms the barrier, causing irritation and rebound dryness. Alternate nights — retinoid one evening, acid the next. This preserves efficacy while protecting the skin.
What is the sandwich method?+
Apply moisturiser, then retinoid, then moisturiser again. It slows retinoid penetration, reduces stinging and flaking, and preserves the active's efficacy. Ideal when building tolerance or for reactive skin — and good practice generally.
Do I need a different moisturiser at night?+
Often yes. A night moisturiser can be richer and more reparative than your day one, focusing on ceramides, peptides and lipids rather than SPF and antioxidants. The barrier does its rebuilding overnight, so this is when reparative ingredients matter most.
When should I apply eye cream?+
Eye cream belongs in the evening, after treatment and before face moisturiser, applied with the ring finger in light tapping motions. The eye area is thin and prone to dehydration; a dedicated formula with peptides and hydrators is more appropriate than face product here.
