Transderma Vitamin A Retinol Serum — Minimalist Retinoid Formula, 15 ml
Transderma Vitamin A is a pure four-ingredient professional retinoid serum designed for skincare specialists and advanced home users. Formulated by Japan Natural Laboratories, it pairs Retinyl Palmitate — the gentlest ester form of Vitamin A — with ultra-moisturising Squalane, deep-penetration enhancer Dimethyl Isosorbide, and protective Vitamin E Acetate. The result is a stable, fragrance-free, alcohol-free night serum that delivers retinoid renewal with minimal irritation risk. Part of the Transderma trilogy alongside Transderma C (Vitamin C) and Transderma R (Resveratrol).

Key Benefits
- ✓ Retinyl Palmitate (Vitamin A ester) — stimulates cell turnover to help soften fine lines and improve skin texture over time
- ✓ Squalane base — lightweight, skin-identical oil that moisturises without clogging pores (comedogenicity: 1)
- ✓ Dimethyl Isosorbide penetration enhancer — carrier that drives actives deeper into the epidermis for improved efficacy
- ✓ Alpha-Tocopheryl Acetate (Vitamin E) — antioxidant protection stabilising the retinoid and neutralising free radicals
- ✓ Fragrance-free & alcohol-free — suitable for sensitive skin beginning a retinoid regimen
- ✓ Beginner-friendly retinoid strength — Retinyl Palmitate requires metabolic conversion, making it gentler than retinol or tretinoin

Cautions
- ⚠️ Do not use during pregnancy or breastfeeding — retinoids (including Retinyl Palmitate) are generally avoided during pregnancy as a precaution.
- ⚠️ Apply SPF the following morning — retinoids increase photosensitivity.
- ⚠️ Avoid contact with eyes and lips.
- ⚠️ Do not combine with strong AHAs, BHAs, or other retinoids in the same application step.
- ⚠️ Initial redness or dryness may occur as skin adjusts — reduce frequency if irritation persists.
- ⚠️ Patch-test recommended before first use.
- Store away from heat and direct light. Keep out of reach of children.
- Discontinue and consult a dermatologist if irritation or allergic reaction occurs.

Frequently Asked Questions
What is the difference between Retinyl Palmitate and regular Retinol?
Retinyl Palmitate is an ester form of Vitamin A that must be converted by skin enzymes into retinol, then into retinaldehyde, and finally into retinoic acid (the active form). This three-step conversion makes it gentler and slower-acting than retinol, making it a good starting point for retinoid beginners or those with sensitive skin.
Can I use Transderma Vitamin A with Transderma C and Transderma R?
Yes. The Transderma trilogy (A / C / R) is designed to be layered. A recommended approach: use Transderma C in the morning with SPF, and alternate Transderma A and Transderma R in the evening on different nights. This avoids potential pH conflicts and gives each active its optimal conditions.
Why does the formula only have 4 ingredients?
Transderma's professional philosophy is minimum necessary ingredients at effective concentrations — no fillers, no fragrance, no preservative cocktails. Squalane serves as the vehicle, Dimethyl Isosorbide boosts penetration, Vitamin E stabilises the retinoid, and Retinyl Palmitate is the active. That's all that's needed.
Is this suitable for daytime use?
No. Retinyl Palmitate and other retinoids should be used at night only. UV light can degrade the active and potentially cause photosensitivity. Always apply broad-spectrum SPF 30+ the following morning.
How long before I see results from Retinyl Palmitate?
Due to the multi-step conversion to retinoic acid, results typically take longer than with pure retinol — expect 8–12 weeks of consistent use before visible improvements in fine lines and skin texture. Patience and consistency are key.
