Here it is:
EVENING Reboot Serum 1.52%
A retinoid night oil that works the way your skin does, no conversion steps, this is straight up retinoic acid.
1.52% HPR · Anhydrous · Small Batch · San Francisco
Renewal without the harsh awakening.
Most retinol products ask your skin to do the work — converting retinol through multiple enzymatic steps before a single receptor is activated. Evening Reset No. 1 takes a different path entirely. Formulated with 0.5% Hydroxypinacolone Retinoate (HPR), a retinoic acid ester that binds directly to retinoid receptors without any conversion, it delivers clinical-level renewal from the first drop. No waiting. No irritation cascade. No dryness.
Suspended in a water-free oil matrix with bakuchiol, squalane, and four nourishing botanicals, this is the retinoid your skin has been waiting for.
The Science
Direct retinoid activity. Genuine gentleness.
Tretinoin is retinoic acid itself — direct, powerful, and often too aggressive for daily use. Traditional retinol works more gently only because it must convert through two enzymatic steps before reaching those same receptors, and much is lost along the way. HPR is different: it is a retinoic acid ester that binds directly, skipping the conversion entirely, but with a gentler receptor affinity. The result is true retinoid activity — collagen stimulation, accelerated cell turnover, refined texture — delivered without the inflammation, peeling, or dryness associated with either retinol or tretinoin.
At 0.5% in an anhydrous environment, HPR remains fully stable and potent from the day you open it to the last drop.
What's Inside
1.52% HPR (Hydroxypinacolone Retinoate)
A direct retinoic acid ester that activates retinoid receptors without conversion. Clinical renewal, genuine tolerance.
Squalane
Biomimetic hydration that penetrates deeply while sealing in overnight moisture. Your skin recognizes both as its own.
Jojoba Oil
Technically a liquid wax, not an oil — it mirrors your skin's natural sebum to balance without congesting.
Vitamin E
Antioxidant protection for your skin and the formula itself — preserving HPR's potency through every use.
Who It's For
Dry & Mature Skin
Traditional retinoids strip what dry skin can least afford to lose. This formula floods skin with moisture while the HPR works — no tightness, no flaking.
Sensitive Skin
HPR's gentler receptor affinity plus bakuchiol's calming properties make this suitable for reactive skin types who've struggled with every other retinoid.
Retinoid Beginners
Start with real retinoid activity — not a compromise. The nourishing oil base minimizes any adjustment period while delivering visible results from early on.
Experienced Users
Even those well-acquainted with retinoids will find something new here: results without any of the harshness, in a texture that feels like a ritual rather than a regimen.
The Experience
This is not the clinical, slightly-anxious experience of applying a traditional retinoid. Evening Reset No. 1 glides on like silk, absorbs without residue, and works while you sleep — so you wake to visibly smoother, more luminous skin that feels exactly as good as it looks. Handcrafted in small batches in San Francisco.
