Good Genes All-In-One Lactic Acid Treatment

Good Genes contains lactic acid, an alpha hydroxy acid (AHA). While topical lactic acid is not on the same restriction list as retinoids or hydroquinone, AHA use during pregnancy is considered a "use with caution" category. The product contains no retinoids, hydroquinone, salicylic acid, or chemical sunscreens. However, since no product is definitively FDA-approved for use during pregnancy, you should always consult your OB-GYN or midwife before incorporating any active treatment — including this one — into your routine while pregnant or nursing. Some dermatologists advise limiting AHA use to occasional, low-concentration applications during pregnancy.

Good Genes is NOT definitively fungal acne safe. The formula contains two ingredients of concern for Malassezia: (1) Saccharomyces Cerevisiae (Yeast) Extract — a fermented ingredient that may feed Malassezia yeast, and (2) Caprylic/Capric Triglyceride — a fatty acid ester that is known to be a Malassezia food source. It also contains Leuconostoc/Radish Root Ferment Filtrate. If you have active fungal acne (malassezia folliculitis), do a patch test on a non-face area first and monitor closely. During a fungal acne flare, consider a FA-safe lactic acid alternative such as The Ordinary Lactic Acid 10% + HA, which has a simpler, FA-safer formula.

Yes, but with care and good layering strategy. With Vitamin C: Many users layer Good Genes first, followed by a Vitamin C serum (such as Sunday Riley CEO 15% Vitamin C) — this is even recommended in Sunday Riley's own AM routine. Both are compatible when applied separately and allowed to absorb. With Retinol: Do NOT use in the same routine step. AHAs can increase skin sensitivity and may destabilize retinol formulas. Alternate evenings (AHA one night, retinol the next) or apply retinol after Good Genes has fully absorbed (PM only). With other AHAs/BHAs: Avoid doubling up in the same application — this dramatically increases irritation risk and can compromise the skin barrier. Use Good Genes alone as your exfoliant for the routine.

Good Genes is formulated for all skin types and this is backed by clinical testing. It performs best on oily, combination, dry, and mature skin types. The 5% lactic acid is gentle enough for near-daily use, and the soothing botanical blend makes it one of the more tolerable AHA treatments for sensitive skin when introduced gradually. It is particularly recommended for those targeting fine lines, dullness, dark spots, uneven texture, and congested pores. The only exceptions are those with active fungal acne (see above) or extremely reactive/compromised skin barriers — those groups should patch test carefully and potentially seek an alternative.

Results vary by concern. For an immediate glow and temporary plumping: you will see and feel results within the first 3 minutes of application — this is a clinically validated claim. For texture improvement and pore clarity: expect visible changes within 1–2 weeks of consistent use (2–3x per week initially). For dark spot fading and brightening: noticeable improvement typically appears at the 3–4 week mark. For fine line reduction and anti-aging benefits: cumulative results develop over 6–12 weeks of regular use. The brand recommends using consistently for 8 weeks to fully evaluate anti-aging outcomes. Skipping SPF will counteract brightening results.

Good Genes is applied early in your routine — after cleansing (and toner if used), but before heavier serums, oils, and moisturizer. The recommended order is: (1) Cleanser → (2) Toner (optional) → (3) Good Genes → (4) Additional serum / Vitamin C → (5) Moisturizer → (6) SPF (AM). Sunday Riley specifically recommends applying it before a treatment oil, then moisturizer. It can also be layered after a treatment oil if skin is very dry. It is a leave-on treatment — do not rinse off. Use AM or PM (beginners should start PM to minimize SPF dependency risks).

Good Genes has a comedogenic rating of 1 out of 5 — considered very low-risk for pore clogging. The key emollient ingredients, squalane (rating 1) and caprylic/capric triglyceride (rating 1), are both lightweight and well-tolerated by oily and acne-prone skin. The lactic acid itself actively helps clear pores by dissolving dead skin cell buildup and excess sebum. The formula is verified as non-comedogenic. Some users with very pore-sensitive or acne-prone skin may experience an initial adjustment period (sometimes called "purging"), where pre-existing congestion is cleared before the skin fully acclimates — this is typically temporary.

Good Genes has a Period After Opening (PAO) of 12 months. The PAO symbol is printed on the packaging (an open jar icon with "12M"). The locking pump design helps minimize contamination and oxidation. Once opened, store in a cool, dry place away from direct sunlight. If you notice any change in color, texture, or scent before 12 months, discontinue use. For the 1 oz (30 ml) size used daily (1–2 pumps), expect it to last approximately 2–3 months. The 1.7 oz (50 ml) lasts approximately 3–5 months with daily use.
