Skin-Nomad's Take — At a Glance
- Retinal 0.1%, Collagen 1% and Peptide 1% in one evening serum
- Lightweight, cooling gel-cream texture that layers easily under moisturiser
- For normal, dry and combination skin ready to step up from retinol
Retinal is the retinoid one step closer to the form skin actually uses, which is why 0.1% of it does real work on fine lines and texture. THOME, a Seoul brand bringing professional-grade formulas into home routines, pairs it with 1% collagen and 1% peptide in the CPR Triple Synergy Wrinkle Care Serum, so hydration and firmness arrive with the retinoid rather than after it. On THOME's clinical testing, smile lines looked 15% softer after two weeks.*
Key Benefits
- Retinal speeds cell turnover and collagen production. At THOME's stated 0.1%, it smooths fine lines and evens out rough texture over weeks of use, and it is the active behind the serum's clinical results.
- Collagen at 1% plumps the surface. Hydrolysed collagen holds water in the upper layers of the skin, so the serum leaves skin looking smoother and fuller from the first application.
- Palmitoyl Tripeptide-5 anchors the peptide complex. It is a signal peptide studied for prompting the skin's own collagen production, and THOME uses it for the look of firmness and elasticity.
- Hyaluronic acid, polyglutamic acid and allantoin keep the retinoid comfortable. Two forms of hyaluronic acid and polyglutamic acid hold water, while allantoin and hollyhock extract calm the skin, which matters most in the first weeks of any retinoid.
Texture & Finish
A light, watery gel-cream that feels cool as it goes on and absorbs quickly. It layers easily into a routine and leaves skin hydrated rather than tight.
Note: Retinal is a retinoid, so this is an evening serum your skin builds up to rather than uses nightly from the start. We don't recommend retinoids during pregnancy or while breastfeeding.
Ideal For
- Skin types: Normal, dry, combination and oily skin; reactive skin will want to start slowly.
- Skin concerns: Fine lines, uneven texture, loss of firmness and dehydration.
- Best used by: Someone moving on from a first retinol who wants a stronger retinoid without giving up hydration.
FAQ
Q: How does retinal compare with retinol?
A: Both are converted by the skin into retinoic acid, the form that acts on cells. Retinol needs two conversions to get there and retinal needs one, so retinal works faster at the same strength. That makes 0.1% retinal a meaningful step up from an entry-level retinol, and it is why the serum pairs it with hydrating and calming ingredients.
Q: Do retinoids thin the skin?
A: No. The flaking some people see in the first weeks is faster surface turnover, not thinning. Over time, topical retinoids thicken the outer layer of the skin and increase collagen in the layer beneath, which is where the smoothing effect comes from.
Q: Can I use CPR with vitamin C, niacinamide or exfoliating acids?
A: CPR is an evening serum, so vitamin C sits naturally in the morning half of the same routine. Niacinamide layers alongside it without any issue. Keep strong exfoliating acids to different evenings while your skin adjusts, and wear sunscreen every morning as the last step of your skincare.
A retinoid is only as good as the weeks you keep using it, and CPR is built around making the first of those weeks comfortable.
* THOME clinical study carried out by P&K Skin Research Center on 32 women after two weeks of use: eye wrinkles reduced 13.27%, smile lines reduced 14.73%, frown lines reduced 10.22%. Brand-commissioned testing rather than an independent trial. Results vary between individuals.
